STAPHYLINID.E. 141 



ish-piceous and the abdomen with a cloud of the same color involving the 

 third and fourth tergites; head small but transverse, parallel at the sides, 

 the eyes well developed and at less than their own length from the base; 

 antennae moderate, rather more rapidly incrassate distally than usual, pale, 

 the second joint but little longer though stouter than the third and almost as 

 long though more slender than the first, the fourth distinctly longer than wide, 

 five to ten from as long as wide to distinctly wider than long, rapidly in- 

 creasing in size, the last a little longer than the two preceding; prothorax 

 strongly transverse, the sides subparallel and nearly straight, rounding 

 strongly in about apical two-fifths, the basal angles obtuse but not in the 

 least blunt, the punctures a little sparser than in the preceding, the rounded 

 impression near the base evident; elytra large, only moderately transverse, 

 equal in width to the prothorax, the suture one-half longer than the latter; 

 abdomen at base nearly as wide as the elytra, gradually and moderately 

 tapering, with feebly arcuate sides, thence to the tip, the asperate punctures 

 numerous as usual. Length 1.65 mm.; width 0.42 mm. Iowa (Cedar Rapids). 



The reticulation of the abdomen is coarse, irregular and distinct. 

 The disposition of the abdominal micro-reticulation is peculiar 

 throughout this genus, the fine lines radiating transversely from 

 each of the asperate punctures. The present species differs from 

 the two preceding in its still more developed elytra and shorter 

 prothorax, with the obtuse basal angles not bluntly rounded as 

 they are in the latter. 



II Head with large shallow umbilicate punctures. 



In this section the antennae are somewhat shorter, more or less 

 rapidly though very moderately incrassate distally and the bristling 

 setae are shorter and less conspicuous than in the preceding. The 

 species are rather closely allied among themselves. 



Luteola Er., may belong here but is larger than any known to me 

 and may possibly be the same asflaveola Mels., which belongs to a 

 very different genus. 



Dolosota lacertina n. sp. Parallel, moderately convex and shining, the 

 punctures fine and close-set, asperate, rather close and asperate on the shining 

 abdomen, where the reticulation is obsolete; color pale testaceous, the head 

 piceous, the abdomen with a large indefinite subapical blackish cloud ; head 

 somewhat large in size, transverse, the eyes convex, slightly longer and less 

 prominent than the tempora, which are also rounded ; antennae rather short, 

 pale, the second joint as long as the first but thinner, distinctly longer than 

 the third, the fourth as long as wide, fifth to tenth wider than long, increasing 

 rapidly in size and width, the last a little longer than the two preceding; 

 prothorax large, strongly transverse, nearly one-half wider than the head and 

 evidently wider than any part of the elytra, rounded at the sides and more
