56 MEMOIRS ON THE COLEOPTERA. 



Atheta (Crephalia) testata n. sp. Subparallel, somewhat convex, shining, 

 the punctures minute and rather sparse, moderately close though scarcely 

 distinct on the elytra, the abdomen coarsely but feebly micro-reticulate, 

 the vestiture fine, not very close; pale brownish-testaceous, the abdomen 

 feebly clouded posteriorly, except at apex, the legs pale; head as long as wide, 

 suboval, the tempora nearly one-half longer than the eyes and more inflated, 

 the carinae wholly obsolete except at the base; antennae pale testaceous, 

 rather short and stout, gradually though moderately incrassate and compact 

 distally, the outer joints strongly transverse, the last longer than the two 

 preceding, the second and third moderately elongate, mutually similar 

 in form, the latter much the shorter; pro thorax only slightly transverse, 

 large and convex, much wider than the head and as wide as the elytral base, 

 somewhat widest before the middle but with the sides distinctly and almost 

 evenly arcuate, the basal angles obtusely rounded, unimpressed; elytra 

 short and transverse, the sides straight and diverging, the suture equal in 

 length to the prothorax; abdomen wide, only slightly narrower than the 

 elytra, parallel, the tergites subequal and short. Length 1.38 mm.; width 

 0.38 mm. Pennsylvania (Philadelphia). 



This species is one of our smallest of the true Athetids; it is 

 probably fungivorous in habits. 



Nemota n. subgen. 



The form is here rather stout, the elytra greatly developed, the 

 middle coxae slightly separated, the mesosternal process extending 

 to their middle, the tip very acute, subaciculate and separated from 

 the transverse and feebly, medially and obtusely cuspid metaster- 

 num, by a very long sunken acute ridge. The hind tarsi are slender, 

 with the first three joints decreasing rather rapidly in length, the 

 first much longer than the second, and the apices of the elytra are 

 not definitely sinuate laterally. Male sexual marks are very feeble. 



Atheta (Nemota) paganella n. sp. Moderately stout and convex, rather 

 shining, the abdomen with coarse reticulation posteriorly, obsolescent basally, 

 the punctures throughout very fine, moderately close on the elytra, the 

 pubescence not dense, rather coarse; body, legs and antennae deep black 

 throughout; head slightly transverse, parallel, the eyes prominent, at evi- 

 dently more than their own length from the base, the rounded tempora 

 barely perceptibly more laterally prominent, the carinae obsolete except at 

 the extreme base; antennae rather thin, moderate in length, gradually feebly 

 incrassate, the outer joints slightly transverse, the last rather stouter, grad- 

 ually acutely pointed, fully as long as the two preceding, the second and 

 third elongate, the former barely visibly the longer; prothorax rather small, 

 moderately transverse, distinctly wider than the head and narrower than 

 the elytra, slightly widest anteriorly, the sides moderately rounded, straighter 

 basally, the basal impression distinct; elytra large, parallel, nearly as long 

 as wide, very much longer as well as wider than the prothorax; abdomen
