164 THE CANADIAN ENTOMOLOGIST 



Lathrobium shermani, n. sp. 



Form moderate; reddish brown, shining, pubescent. Antennse 

 rather stout, scarcely reaching the bases of the prothorax, outer 

 joints moniliform. Head as wide as long, a little wider behind, 

 the angles broadly rounded, surface rather sparsely punctate. 

 Eyes wanting, but in their place a small, nearly smooth, whitish 

 spot of about the size of the second antenna! joint; beneath sparsely, 

 punctate, the gular sutures rather widely separated, most ap- 

 proximate at about the middle of their length, where they are dis- 

 tant by about the width of the penultimate joint of the maxillary 

 palpi. Neck one-half as wide as the prothorax, the latter oblong 

 oval, narrower than the head, longer than wide, just perceptibly 

 narrowed behind, the angles all rounded, the posterior ones a little 

 more broadly so, surface, finely rather sparsely .confusedly punctate, 

 with narrow, ill-defined, smoother median line. Elytra distinctly 

 shorter than the prothorax, humeri small, sides divergent, the 

 width at the apex equal to that of the prothorax, punctures with- 

 out serial arrangement, coarser than those of the prothorax, 

 mutually distant by their own diameters or a little more; wings 

 undoubtedly vestigial or wanting. Abdomen gradually a little 

 widened to the fifth segment, punctuation finer, not close. Legs 

 concolorous; front thighs stout, broadly angulate subapically be- 

 neath; front tarsi broadly dilated, hind tarsi three-fifths as long as 

 the tibiae, basal joint short, terminal joint longer than the two pre- 

 ceding. Length 6.3 mm.; width L15 mm. North Carolina, 

 Grandfather's Mt.. 4.000-5,000 ft., September. (F. Sherman 

 collector.) 



The unique type is a male, having the sixth ventral segment 

 broadly, rather deeply, arcuately emarginate, the segment bearing 

 about the middle of its length on either side of the median line a 

 short, transverse comb of closely placed, porrect, black spinules, 

 about eight in number. 



This species is remarkable in being the first blind — or virtually 

 blind — Lathrobiid to be discovered in our fauna. In the European 

 fauna the members of the subgenus Glyptomerus are similarly de- 

 prived of normal eyes, but the characters of Glyptomerus, as given 

 by Casey in his Revision of the American Paederini do not well fit 

 our species. L. shermani is perhaps nearest to Abletohium pallescens
