144 MEMOIRS ON THE COLEOPTERA. 



prothorax convex, transverse, rounded at the sides, only slightly narrowed 

 apically, much wider than the head but equal in width to theelytral apex, the 

 basal fovea small and scarcely traceable; elytra short and transverse, with 

 evidently diverging sides, the suture not quite as long as the prothorax; ab- 

 domen very feebly tapering to subparallel, almost as wide as the elytra, the 

 border rather thick. Length 1.6 mm.; width 0.35 mm. Rhode Island 

 (Boston Neck), Pennsylvania (Philadelphia), District of Columbia and North 

 Carolina (Asheville). 



To be known by the short elytra. The prothorax is relatively 

 not so wide as in the other Atlantic coast forms, such as lacertina 

 and euphonia. It does not seem to vary notably in the several 

 local environments mentioned. 



Dolosota serva n. sp. Fusoid, rather convex and shining, having the usual 

 rather close-set asperate punctures, rufo-piceous in color, the head and abdo- 

 men blackish, the latter pale basally and barely so at apex; head relatively 

 small, transverse, the eyes prominent, at a little less than their own length 

 from the base, the tempora not at all prominent, at first parallel, then round- 

 ing to the base; antennae pale throughout, rather short, gradually and very 

 sensibly incrassate distally, of the usual type; prothorax transverse, convex, 

 broadly rounded at the sides and narrowing anteriorly, much wider than the 

 head, fully as wide as the elytral base but scarcely so wide as the apex, 

 unimpressed ; elytra rather large, only moderately short, the sides somewhat 

 strongly diverging, the suture fully a third longer than the prothorax, abdo- 

 men very feebly tapering and with feebly arcuate sides throughout, distinctly 

 narrower than the elytra. Length 1.7 mm. ; width 0.37 mm. Massachusetts, 

 Blanchard. 



The only other species in which the elytra approach the develop- 

 ment that they have here is alumna, and there they are narrower, 

 being overreached at the sides by the prothorax; serva also has the 

 coloration more sombre than usual and the general facies quite 

 distinctive. 



Microlia n. subgen. 



In this group the sterna, tarsi, fully developed and entire cephalic 

 carinse and greatly inflexed hypomera are nearly as in Dolosota, 

 but the antennae are quite different, being very short, with the outer 

 joints rapidly very stout, transverse and compact. The type is 

 the following: 



Dolosota (Microlia) pernix n. sp. Rather stout, fusiform and convex, shin- 

 ing, very finely and not densely or asperately punctate, the abdomen feebly 

 so and with the reticulation unusually large and irregular, without trace of the 

 peculiar radiating arrangement of the preceding group; color pale flavo-tes- 

 taceous, the head not darker, the abdomen blackish, pale basally and at apex,
