Eumolpus, Fabr. 



1. E. longipes. Fuscous, clothed with a dense ashy-pubescence ; feet long, 

 2 1. long. Pennsylvania. 



Brown, densely ashy-pubescent: head dark brown, densely and deeply 

 punctured, ashy-pubescent; a longitudinal impressed frontal line: labrum 

 piceous : antenna; slender, long, rather filiform, fuscous, with three or four 

 basal joints testaceous ; eyes deep black ; palpi dull testaceous : thoraxlonger 

 than wide, much narrower than the elytra, slightly wider behind than before, 

 subcylindric, with the sides obtusely rounded ; densely and profundly punc- 

 tured : scutellum small, densely ashy-pubescent : elytra with shallow punc- 

 tured strias, punctures close-set; interstices transversely wrinkled, minutely 

 punctured : outer basal angles prominent; apex rounded ; beneath and feet 

 blackish-brown, ashy-sericeous or finely ashy-pubescent ; the feet more than 

 ordinary long; posterior and intermediate femora at base, testaceous. 



2. E. villosulus. Ferruginous, pubescent ; antenna;, palpi and feet, testa- 

 ceous-yellow. If 1. long. Pennsylvania. 



Eumolpus villosus, Melsh. Catal. 



Ferruginous : very minutely and densely rugose, clothed with minute, short 

 hairs, with an obtuse, longitudinal frontal indentation ; antenna as in the 

 preceding species ; yellowish ; labrum and palpi similarly colored ; eyes deep 

 black : thorax transverse, wider at base than at apex, with the sides rounded, 

 middle of anterior edge raised ; rugulose and clothed like the head ; obtusely 

 indented on the middle of each lateral margin and in front of the scutel : 

 elytra lighter and less pruinose than the bead and thorax ; pilose like the 

 thorax, with the hairs more distinct ; with fine and somewhat obsolete punc- 

 tured striae ; interstices fine, convex ; exterior basal angles moderately promi- 

 nent; apex acutely rounded: feet testaceous, or testaceous-yellow. It be- 

 longs perhaps to Chevrolat's subgenus 3Iyochrous. 



Var. ? a. Smaller; head, thorax and elytra light rust-red, the last with 

 a common, indeterminate black spot on the middle. Eumolpus plagiatus, 

 Melsh. MS. 



3. E. pubescens. Cupreous, sparsely asby-pubescent ; head with a pro- 

 found frontal indentation. 1| 2 1. long. Pennsylvania. 



Eumolpus pubescens, Melsh. Catal. 



Dull cupreous, or brassy-brown, sparsely ashy-pubescent: head densely 

 punctured, with a large, profound indentation on the front; labrum and 

 palpi, black-piceous; eyes and antenna; black, the latter moderately long, 

 with five terminal joints thicker than the preceding ones, which are brassy ; 

 second joint robust; joints third till sixth inclusive, equal ; thorax trans- 

 verse, feebly waved behind, with the front slightly advanced in the middle ; 

 sides rounded; rather wider behind than before: minutely punctured, 

 densely transversely wrinkled : scutellum obtuse-triangular: elytra wider 

 at base than the thorax, narrowed to the apex, which is rounded; with ob- 

 scure and irregular series of small punctures ; transversely rugulose ; 

 humeral tubercles prominent : beneath rugosely punctured : feet dull 

 cupreous, tinted with greenish.
