Coleopterological Notices, V. 297 



visibly narrower ; sides subparallel and feebly arcuate ; humeri wholly con- 

 cealed ; disk feebly, transversely convex. Abdomen fully one-half longer than 

 the anterior parts, at base nearly as wide, and at the apex of the fifth segment 

 two-thirds as wide, as the elytra ; sides straight ; border rather thick ; fifth 

 segment two-thirds longer than the fourth. Legs rather short and thick, the 

 hind tarsi much shorter than the tibiae, with the first joint a little longer than 

 the next two. Length 2.0 mm. ; width 0.45 mm. 



Rhode Island (Boston Neck). 



Readily separable from minuta Sachse, by the pale prothorax and 

 dark elytra. The antennae are unusually short. 



O. lilieata* — Narrow and sublinear, convex, black, tlie pronotum piceous- 

 blatk, the elytra feebly rufescent; antennae pale at base; legs pale flavo- 

 testaceous throughout; integuments feebly shining, the pronotum and abdo- 

 men extremely minutely and excessively densely punctate, the elytra equally 

 densely but rather more strongly and subasperately, the head a little less 

 finely and more sparsely ; pubescence extremely minute, dense, the abdomen 

 as usual with an apical fringe of longer hairs on each tergite, but having only 

 a very few longer set« toward apex. Head as long as wide, evenly convex, 

 fully three-fourths as wide as the prothorax ; eyes moderate, at more than 

 their length from the base ; antennae rather long, loose, feebly iucrassate, 

 extending to basal third of the elytra, the third joint elongate, only slightly 

 though visibly shorter than the second, joints increasing only very slightly in 

 width toward apex, six to ten quite distinctly wider than long, the eleventh 

 rather large, ogival at tip, fully as long as the two preceding. Protliorux — from 

 above — only one-third wider than long, the sides parallel and evenly, broadly 

 arcuate, widest at the middle; base and apex equal, feebly arcuate, the former 

 fitted rather closely to the elytral depression ; basal angles obtuse and blunt 

 l)Ut very evident ; disk not distinctly imi^ressed. Elytra short and transverse, 

 quite distinctly shorter than the prothorax, at base as wide as the prothorax, 

 and, at apex, just visibly wider ; sides perceptibly divergent and straight from 

 base to apex ; humeri not exposed ; disk broadly, feebly impressed along the 

 suture in more than basal half. Abdomen nearly one-half longer than the 

 anterior parts, at base distinctly narrower than the elytra; sides subparallel, 

 narrowed toward apex; border moderate; fifth segment one-half longer than 

 the fourth ; sixth greatly visible, a little narrowed and parabolic but as long 

 as the fifth. Leys moderate in length, slender, the hind tarsi but slightly 

 sliorter than the tibiae, with the first joint a little longer than the next two. 

 Length 2.1 mm. ; width rather more than 0.4 mm.

Rhode Island. 



This species is rather aberrant, not only in the subquadrate form 

 of the prothorax, but in the total absence of the infralateral carina 

 of the head. I cannot see, however, that it differs otherwise from 

 Oxypoda.
