150 MEMOIRS ON THE COLEOPTERA 



Differs from dissensa, which occurs in the same locality, in its 

 larger head, very much less apically incrassate antennae, with far less 

 unequal ninth and tenth joints and in the narrower, still more 

 apically narrowed abdomen; in coloration, in the rather loose 

 feeble punctuation and coarse vestiture the two are, however, 

 rather similar. 



Pseudota clienta n. sp. Parallel, moderately convex, shining; head 

 dark, the prothorax paler, rufo-piceous, the elytra still paler and brown- 

 ish-flavate, broadly blackish about the scutellum, the abdomen black, 

 palish at apex, the legs very pale; punctures fine and feeble though close, 

 sparser on the head and sparser, though numerous, on the more polished 

 abdomen, the vestiture very short, fine and inconspicuous; head rather 

 transverse, barely two-thirds as wide as the prothorax, the eyes at two- 

 thirds their length from the base, the tempora not quite so prominent, 

 parallel and nearly straight, gradually rounding to the base, the carinae 

 fine, entire; antennae blackish, moderately short, thick, slender and 

 testaceous basally, the second and third joints long and equal, fourth 

 broader, rather transverse, five to ten subsimilar though gradually in- 

 creasing, short, about two-thirds wider than long, the last ogival, a little 

 longer than the two preceding; prothorax well developed, one-half wider 

 than long, parallel and evenly, distinctly rounded at the sides, the 

 median line very finely and faintly impressed and with a rounded shallow 

 ante-scutellar impression; elytra rather short and transverse, with 

 slightly diverging and nearly straight sides, at base equal in width to the 

 prothorax, the suture only about a fifth longer than the latter; abdomen 

 distinctly narrower than the elytra, perfectly parallel, with almost 

 straight sides, the fifth tergite but little longer than the fourth, the first 

 three impressed at base as usual. Length 2.2 mm.; width 0.48 mm. 

 Mississippi (Vicksburg). 



Distinguishable from any of the other eastern species by the 

 relatively larger prothorax and noticeably short elytra. The middle 

 coxae are rather widely separated, the mesosternal process long, 

 gradually acute but not at all aciculate or prolonged, the meta- 

 sternal projection very short and broadly, obtusely angulate, the 

 longitudinal ridge not much sunken and broadly, feebly convex 

 transversely. 



Pseudota vana n. sp. Moderately stout, feebly convex, rather dull 

 in lustre, the punctures very close throughout and unusually strongly 

 asperate, numerous but smaller on the more shining abdomen, becoming 

 gradually sparse posteriorly, the pubescence short; color piceous-black, 

 the head and abdomen deep black, the legs nearly black, short; head 

 transverse, more than three-fourths as wide as the prothorax, the eyes 

 prominent, at two-thirds their length from the base, the less prominent 

 tempora converging and arcuate to the base, the carinae fine, subentire;
