HlSTERID^ 263 



than one-half longer than the prothorax, very feebly inflated basally, 

 the surface very smooth but with some fine sparse punctures inwardly 

 toward apex; four discal striae very long, subequal, extending to apical 

 sixth, the two outer feebly, the inner more, arcuate, the fourth arched 

 and uniting with the deep sutural, which extends very nearly to the 

 apex; in the space between the fourth and sutural striae there is a long 

 straight stria, extending from basal to apical third and slightly oblique; 

 outer subhumeral wanting, the inner very long and, like the first dorsal, 

 extending from near the base to near the apex; all the striae are punctate, 

 excepting the oblique humeral, which extends between the inner sub- 

 humeral and the first dorsal and is obsolescent basally; pygidium finely, 

 not densely punctate, bitumorose at apical third, thence flat and more 

 strongly punctate to the rounded apex, which is paralleled at some 

 distance internally by an arcuate stria; sterna normal for this group, 

 the side-pieces of the hind body not coarsely but extremely densely 

 punctate; anterior tibiae with the last three or four serrules larger than 

 the others. Length 3.6 mm.; width 2.4 mm. Florida (Funiak). 



The formation of the lateral striae, very elongate discal striae 

 and the isolated stria between the fourth and sutural, are very 

 remarkable characters of this species, not suggested in any other 

 known to me; perhaps the singular pygidial structure in the unique 

 type may be sexual in character. 



Saprinus insolitus n. sp. Form, convexity and general characters 

 somewhat as in the preceding, rather smaller, strongly convex, blackish- 

 piceous, the pygidium and legs rufous; head as in repens; prothorax 

 shorter, though less than twice as wide as long, the sides moderately 

 converging and feebly arcuate, more rounded apically; marginal groove 

 fine, entire; surface smooth, gradually becoming finely, sparsely punc- 

 tulate toward the sides, and again nearly smooth along the edge, these 

 more visible punctures in the form of fine and longitudinal sublunuliform 

 lines; base and fovea as in repens, the elytra similar in form, striation 

 and sculpture, except that the punctures toward the inner apical angles 

 are still finer and sparser; discal striae all equally arcuate, long as in repens 

 and punctate, the fourth, sutural and also the isolated intermediate 

 stria similar, but, between the isolated stria and the sutural, there is 

 another, shorter and more oblique isolated stria; outer subhumeral 

 wanting, the inner beginning at the end of the oblique humeral and 

 extending to apical fifth; pygidium convex, with very feeble and moder- 

 ately close scratch-like punctures, the surface tumid apically in the form 

 of a compressed longitudinal umbo; sterna normal, the tibiae nearly as 

 in repens. Length 2.8 mm.; width 1.9 mm. Florida (Clearwater). 



Although agreeing with repens in most of its characters, this 

 species differs radically in the form of the pygidium and in the 

 position and extent of the inner subhumeral stria; it also differs 

 in the much feebler punctuation, smaller size, shorter prothorax 

 and sparser punctuation of the sternal side-pieces.
