HlSTERID^E 26l 



an impressed series of punctures extending almost to the apex; outer 

 subhumeral short, basal and close to the lateral stria, the inner very short 

 and medial; pygidia strongly and densely punctate; prosternal striae 

 parallel, not widely distant, diverging at base, slightly converging anteri- 

 orly, ending at apical fourth, the included surface distinctly convex; 

 apical edge finely beaded; mesosternum strongly, rather closely punctate; 

 anterior tibiae much dilated and with rounded outline distally, having 

 seven or eight short and very stout external spinules. Length 3.0 mm.; 

 width 2.0 mm. Massachusetts (Framingham), Frost. One example. 



Not closely allied to any other species; from p&minosus, near 

 which it should stand, it is distinguishable at once by its strong 

 close punctuation and shorter elytral striae. 



Saprinus obsoletus n. sp. Oval, convex, the form, size, color and 

 brilliant lustre almost as in moniliatus; head finely, rather sparsely punc- 

 tate, with a small occipital fovea and two fine feeble oblique anterior 

 striae; prothorax distinctly less than twice as wide as long, the sides 

 strongly converging from the base, barely at all arcuate, gradually round- 

 ing anteriorly, the marginal line fine, almost entire; surface with remote 

 and extremely minute punctulation, which gradually becomes distinct, 

 though rather fine and well separated punctures, broadly toward the 

 sides, the confused punctures along the base coarser medially; impres- 

 sions all wanting; elytra one-half longer than the prothorax, barely 

 visibly inflated subbasally, punctate only in apical three-fifths suturally 

 and two-fifths in line with the second stria, outside of which the surface 

 is very smooth and polished, without trace of inner or outer subhumeral 

 striae, the oblique humeral distinct; four discal striae strong, punctate, 

 somewhat hooked at base, the first extending two-thirds, the others to 

 distinctly behind the middle, the fourth arching at base and joining an 

 extremely short basal remnant of the sutural. which is entirely obsolete 

 except from just before the middle nearly to the apex; punctures sparse 

 and coarse, becoming finer and closer toward tip; propygidium coarsely, 

 densely punctate, gradually finely so toward base, the pygidium convex, 

 coarsely and densely punctate basally, gradually almost punctureless api- 

 cally; prosternal striae extending almost to the apex, but not to the base, 

 which region is smooth and punctureless, the striae most approximate 

 slightly behind the middle, the included surface convex and punctate; 

 anterior tibiae with seven or eight small external serrules. Length 2.8 

 mm.; width 1.9 mm. New York (Peekskill), Sherman. 



This species also is widely distinct from any other, but may be 

 associated with the California!! pceminosus, differing however in 

 many ways, as may be inferred. 



Group V (lugens). 



In this group the prosternal striae diverge in front but do not 

 end in evident foveae, as they do in the next group. A few un- 

 described species are at hand as follows:
