HARPALIKLE 165 



but here, in addition, the hind femora are inflated and strongly 

 dentate beneath and the anterior tarsi are rather broadly dilated 

 and clothed beneath with conspicuous squamules. The type 

 species is Trichopselaphus subiridescens Chd., of southern Brazil. 

 Its relationship with Gynandropus and Stenomorphus is distinctly 

 indicated by the form of the female anterior tarsus, where the basal 

 joint is conspicuously larger than any of the following joints. La- 

 cordaire does not say whether the elytra are triseriately punctate 

 as in Discoderus, but in the single Mexican species described by 

 Bates, T. minor Bates, the second, fifth and seventh striae are said 

 to be inconspicuously punctured in series. Mr. Bates states (Biol. 

 Cent.-Amer., I, i, p. 62) that the Venezuelan genus Anisocnemus 

 Chd., belongs in this vicinity, being especially allied to Discoderus , 

 but, according to the description of Lacordaire, this affinity could 

 only be surmised from the dilatation of the hind femora; in the very 

 acute basal angles of the prothorax it departs widely from Disco- 

 derus; there may however be a closer affinity with Trichopselaphus, 

 though this seems to be unsuspected by the author of the "Genera," 

 who places the genus just before Harpalus.

That so conspicuous and aberrant a generic type should, in the 

 thickly settled state of Illinois, so long have remained undiscovered, 

 is merely a reminder that our Coleoptera are still only known in 

 comparatively small part ; the peculiar pallid coloration of the body 

 gives an appearance of immaturity, which may however possibly 

 have led many a collector to reject it as undesirable material 

 always an unsafe procedure. The body is oblong, subparallel and 

 strongly convex, with broadly rounded basal angles of the pro- 

 thorax, so that in every way except color it closely resembles a very 

 large Discoderus, but the middle tibiae of the male are straight and 

 unmodified and the anterior and middle tarsi of that sex broadly 

 dilated and strongly biseriately squamose beneath, exactly as in 

 the genus Harpalus, from which it differs in having three series of 

 substrial elytral punctures as in Discoderus and Selenophorus. The 

 ligula is broadest and rectilinearly truncate at apex and equal in 

 length to the moderate, apically obtuse paraglossae, and the mentum 

 has a broad and sharply triangular tooth, all of which features are
