64 COLEOPTERA RHYNCHOPHORA. 



Alycodes dubiiis Dietz. 

 Ellesclius angustatus Dietz. 



As suspected by Casey, both these species belong to the 

 genus Dorytomus. The former is very like and probably 

 identical with brevicollis Lee, the latter is close to sgiiafuosiis 

 Lee, and quite likely no more than a slight variety of that 

 species. It seems to be a bit narrower than the type of sgtia- 

 mosus, the elytral scales more uniform in width, the tessella- 

 tion more feebly marked. 



Orcliestes armatulus Dietz. 



An examination of the type shows it to be a specimen of 

 Psomus PolitusC^y., in which the elytra are transversely frac- 

 tured each side behind the humeri — presumably by being 

 grasped too tightly with forceps — the posterior edge of the 

 fracture being more prominent and simulating an anteriorly 

 projecting spine when viewed from above. The error is a 

 remarkable and scarcely excusable one, since one would 

 expect the most careful verification of appearances by the 

 describer before announcing so singular and unexpected a 

 character. The true state of affairs is not very difficult to 

 make out on close inspection, and such inspection should 

 have revealed the very approximate eyes, pectoral channel 

 and other features quite impossible in an Orchestes. 



ORCHESTES 111. 

 O. illiiioisensis n. sp. — Black, lustre dull ; pubescence whitish, 

 rather long and conspicuous, recumbent, dense on the scutellum. 

 Antennal funicle 7-jointed, in great part rufotestaceous, club piceous, 

 Prothorax one-half as wide as the elytra, sides parallel in basal two- 

 fifths, hind angles nearly rectangular, punctuation dense but only 

 moderately coarse. Elytra elongate oval, scarcely impressed, striae 

 distinctly impressed, intervals somewhat rugose. Length, 2.35 mm. ; 

 width, 1.2 mm. 



Type. — From Algonquin, Illinois (Nason). A second 

 specimen also from northern Illinois in Mr. Blanchard's col- 

 lection. 



By Dietz's table this falls neoiX parvicollis, which is a some- 

 what stouter species with more evidently impressed elytra 

 and shorter blackish pubescence. The resemblance to pa Hi-
