92 MEMOIRS ON THE COLEOPTERA. 



the head and evidently narrower than the elytra, parallel, the sides rather 

 more arcuate near apical third, where it is evidently widest, unimpressed; 

 elytra moderately transverse, evidently longer than the prothorax; abdomen 

 nearly as in the preceding, except that the margin ends before the middle of 

 the fifth tergite in a very exceptional manner; tarsi almost similar. Length 

 2.0 mm; width 0.3 mm. Texas (Del Rio), Wickham. 



The antennae, form of the prothorax and abdominal structiue 

 separate this species from decora veiy clearly, although the colora- 

 tion and sculpture are almost identical. 



Noverota personata n. sp. Rather slender, moderately convex, shining, 

 the reticulation very feeble, the ground sculpture of the abdomen coarsely 

 but feebly micro-reticulate; punctures very fine throughout and not dense, 

 the abdomen almost punctureless; color pale yellow-brown, the abdomen 

 black, except the two basal segments, the legs very pale; head parallel, 

 transverse, convex, nearly smooth, the eyes rather convex, shorter than 

 the tempora but equally prominent, the facets moderate though strongly 

 convex and contiguous, the carinse wholly obsolete; antenna? gradually in- 

 crassate and very thick, the outer joints mutually similar and distinctly 

 transverse, the last stouter, obtusely, ogivally pointed, fully as long as the 

 two preceding, the second and third much elongated and equal; prothorax 

 moderately transverse, much wider than the head and narrrower than the 

 elytra, widest but with the sides broadly rounded near apical third, the 

 basal impression extremely small and feeble; elytra a little shorter than wide, 

 much longer than the prothorax; abdomen much narrower than the elytra, 

 parallel, the fifth tergite barely as long as the fourth. Length 1.9 mm.; 

 width 0.35 mm. Virginia (Norfolk). 



This species is at least subgenerically different from the three 

 preceding, but to name all the groups which occur in our fauna 

 would necessitate more than a hundred separate genera and sub- 

 genera. 



Noverota Clemens n. sp. Slender, more depressed, less shining, the micro- 

 reticulation distinct, that of the abdomen much finer than in personata; head 

 and abdomen blackish-piceous, the latter pale basally and at apex, the pro- 

 thorax red-brown, the elytra and legs wholly pale flavate; head slightly 

 transverse, the eyes rather convex, finely but strongly, densely faceted, at 

 much more than their own length from the base, the tempora parallel, rounded 

 and a little more prominent, the carinse fine, extending to the middle; an- 

 tennae piceous, paler basally, rather slender, feebly and very gradually in- 

 crassate, rather long, the outer joints mutually similar in form, obviously 

 transverse, the last rapidly pointed, not stouter, nearly as long as the two 

 preceding, the second and third elongate, the latter slightly the shorter; 

 prothorax rather transverse, almost similar in outline to that of the pre- 

 ceding but less convex and with a distinctly impressed median line extending 

 anteriorly slightly beyond the middle, distinctly wider than the head and 

 slightly narrower than the elytra, the latter slightly shorter than wide, much
