HlSTERIDJE 275 



punctate at the base of the occiput; prothorax long, barely more than 

 one-half wider than long, the long sides moderately converging and 

 broadly, subevenly arcuate from base to apex, but little more rounded 

 apically; surface strongly convex, with close-set ruguliform punctuation, 

 becoming rather strong very broadly toward the sides, the basal confused 

 punctures rather indistinct, becoming obsolete medially; the transverse 

 smoother subbasal area is not definite and has some very minute punc- 

 tulation; elytra only a third or fourth longer than the prothorax, 

 rather strongly inflated subbasally, finely, sparsely and subevenly punc- 

 tured throughout, the punctures apically becoming slightly strigilate; 

 striae one to four gradually a little longer, the first extending to the 

 middle, the fourth distinctly beyond, arched at base, joining the sutural, 

 which is entire though very fine and feeble throughout; all the striae 

 very fine, the short outer subhumeral distinct, diverging slightly from 

 the lateral, the inner a short oblique median line, the basal part of the 

 oblique humeral and first dorsal lying in a slight depression; pygidium 

 not finely but shallowly, loosely punctate, convex; prosternum com- 

 pressed and cariniform anteriorly and without medial striae, flat posteri- 

 orly and with two fine striae, not extending to the middle and gradually 

 feebly converging from the base; lateral lines strongly cariniform, 

 parallel, the concavity within each terminating in an anterior fovea; 

 mesosternum finely, sparsely punctate; hypomera flat, sparsely punc- 

 tate, glabrous, excepting a loose line of short lateral cilia; anterior tibiae 

 with about five short and broad obtuse denticles. Length 2.7 mm.; 

 width 1.8 mm. Nevada (Elko), Wickham. 



The type of this species was sent to me under the name ciliaius 

 Lee., to which however it bears little resemblance; the apical 

 marginal stria of the elytra is entire, but it is said to be obsolete in 

 ciliatus and the frontal line is there said to be only visible at the 

 sides; here there is a very strongly elevated equal carina from side 

 to side; ciliatus is from California. This is one of the species out 

 of harmony with the grouping of Marseul, LeConte and Horn; if it 

 were not for the strong entire frontal carina, it would be an 

 aberrant member of either Group VI or VII of Horn, its pro- 

 sternal characters tending to unite the two. 



Saprinus laciniatus n. sp. Rather narrowly oblong-oval, moderately 

 convex, pale ferruginous throughout; head strongly but not very densely 

 rugose, the occiput with a small smooth spot at the middle; frontal 

 carina thin, even and entire; eyes nearly flat, very finely faceted; large 

 basal joint of the antennae bearing a long tuft of very coarse yellowish 

 setae; prothorax large, three-fourths wider than long, the sides almost 

 evenly arcuate, becoming subparallel basally; apical angles rather nar- 

 rowly rounded; surface shining, the punctures laterally not very strong, 

 well spaced transversely, and in the form of feebly lunuliform longi- 

 tudinal lines, very fine, sparse and subobsolete medially; basal punctures 

 not evident; sides bristling with very long erect yellow hairs; elytra a
