86 MEMOIRS ON THE COLEOPTERA. 



antennae long and very slender, all the joints elongate, the second and third 

 long, equal; prothorax rather small, only slightly transverse, distinctly 

 wider than the head and very much narrower than the elytra, widest and 

 with the sides subprominently rounded before the middle, not definitely 

 impressed; elytra slightly transverse, the punctures very fine and dense but 

 not conspicuous, the suture much longer than the prothorax, the sinus of the 

 elytral apices obsolescent; abdomen much narrower than the elytra, paral- 

 lel, narrowing slightly apically, the fifth tergite (c?) with a slender tubercle 

 at the centre, the sixth with characters almost exactly as in perdita, the 

 sterna similar, the hind tarsi slender, with the first joint much longer than 

 the second and following. Length 3.2 mm.; width 0.65 mm. Central New 

 York. 



Differs from perdita in its more slender form but it is completely 

 congeneric. The original type of this species, which was a female, 

 was lost, but fortunately I found a male which serves for the above 

 description. 



Aloconota (Terasota) intecta n. sp. Slender but more parallel than the 

 last, similar in coloration, lustre and pubescence, the close punctuation very 

 fine; head very well developed, distinctly transverse, the eyes very convex 

 and prominent, a little longer and decidedly more prominent than the tem- 

 pora; central short canaliculation similar to that of the two preceding, the 

 carinse fine but strong and completely entire; antennae rather long, very 

 slender, dusky, paler basally, not incrassate but filiform, all the joints elon- 

 gate, the tenth almost one-half longer than wide, the last equally slender, 

 much shorter than the two preceding, the second and third relatively moder- 

 ately more elongate, equal; prothorax larger, more transverse, slightly wider 

 than the head and a little narrower than the elytra, the sides parallel, sub- 

 evenly and very moderately arcuate, the median line feebly impressed basally; 

 elytra distinctly shorter than wide though a third longer than the prothorax, 

 the apices as in the preceding; abdomen narrower than the elytra, parallel, 

 not narrowing toward tip of the fifth tergite, the sixth (9) very large, semi- 

 circular; sterna nearly as in the preceding, the basal joint of the hind tarsi, 

 however, not longer than the second. Length 3.4 mm.; width 0.65 mm. 

 North Carolina (Asheville). 



Described from a single female, which represents a species almost 

 undoubtedly congeneric with the two pieceding, but differing re- 

 markably in having well developed infra-lateral cephalic carinae 

 and a basal joint of the hind taisi not longer than the second; the 

 notably prominent and well developed eyes are also distinctive. 



Hydrosmecta Thorns. 



The following small frail insects are assigned to this genus, having, 

 as in longula,the middle coxae contiguous, the mesosternum short 

 and the metasternum transverse and not projecting anteriorly;
