ANTHICU8 TOBIAS MARSEUL,ANOTHER TRAMP SPECIES

(COLEOPTERA ANTHICIDAE)

BY F. G. WERNERUniversity o Arizona, Tucson

Among the rather numerous collections o Anthicidae examineclby the author during th past ten years there have been small numberso an unidentified species o tnthicus rom a truly amazing variety olocalities. In the United States, which yielded the qrst examples seen,specimens have turned up rom the Atlantic to the Pacific and romNew England to Florida, including such places as Catarina, Texas andthe Sierra _A_ncha Mountains o Arizona. The author must admit thathe held these specimens to represent an undescribed species and hadprepared a description or publication and designated types. Thena specimen was sent rom Guam, in the Marianas, othersrom Oahuidentified as ztnthic,us mundulus Sharp, and, most recently, otherstrom Jamaica and Venezuela. By this time it had become apparentthat the species must have been introduced into part of the localities.Structurally, it is quite unlike any other species in the New World,especially in the details ot the very elaborate structure surrounding themale primary gonopore. So an Old World source was likely.The true identity of the species was revealed in the British Museum

collection, which the author was privileged to study recently. Speci-mens identified as ztnthicus tobias Marseul trom Aden, India andJava are the same as those previously seen. The type specimen oftobias has not been examined but the specimens at hand agree per-tectly with the original description. Both 3nthicus mundulus Sharpand z/. cervinus LaFertd, under whose names most specimens havebeen misidentited, are quite different.

In the United States, at least, this is not a very abundant species.In most cases only one or a very few specimens have been seen fromany one locality. It may be more abundant on Oahu, if one can judgetrom the number of specimens that have accumulated in collections.In order to help prevent further misidentification in any new areaswhere the species may be found, a brief description and figure aregiven here. The male genitalia are very distinctive. In most cases anexamination of the tip of the tegmen will suffice for the identi(ication

of the species; none other has been seen with a similar conformation.A quick perusal of the British Museum collection and the Pic collec-tion in Paris failed to disclose any species that might be likely close

relatives, at least on external features. However, the author is not

thoroughly familiar with the Old World fauna and may havemissed some species.

dnthicus Tobias Marseul, 1879, L’Abeille 17" 125. Pie, 1911, Coleop. Cat.,pars 3;: 77.Rufous, the antennae, palpi and legs luteous; elytra with a terru-

gineous to piceous area that extends from the basal 2/5 to I/4 to theapex, with the suture pale anteriorly, and with a very pale spot oneach elytron at about I/5 trom the apex. Prothorax and elytraflattened.Head subquadrate, but base rounded and slightly notched at the

middle. Surface smooth, with dense, rather small punctures through-out, even on the midline. Pubescence moderately dense and short,fine, decumbent. Eyes moderately large, prominent. Antennae slenderbut slightly thickened apicaIly. Prothorax widest at apical third,flattened, with punctures and pubescence similar to those of head.Elytra subparallel, flattened; omoplates slightly elevated; suture

elevated on apical halt:. Surface smooth, moderately densely punctured,the punctures on the basal portion slightly larger and feebly asperate,those behind fine and small. Pubescence golden in the pale zone,brown over the dark markings, decumbent, fine, directed obliquelylaterally in the basal fourth, not conspicuous. Tactile setae veryshort but erect. Male pygidium flattened, with truncate apex; hypopy-

glum with a shallow, V-shaped notch. Aedeagus with a dorsal ridgeand subapical notch on the tegmen; gonopore armature very large andcomplex, not inverted.The total length of the specimens examined ranges, from 2.6 to 3.I

ram. Both the pale area at the base of the elytra and the subapicalspots vary somewhat in size. The most similar-looking species in theNorth American tauna is ztnthic,us cervinus, which has curved pubes-cence on the elytra in most parts of its range, elytra that are not

flattened, and very different male genitalia.
