subparallel behind the middle ; hind angles acute, prolonged backwards and 

 strongly carinate; disc moderately convex sj)arsely punctured. Elytra as 

 broad as thorax, sides feebly rounded and gradually narrower to apex j disc 

 moderately convex feebly striate coarsely punctured becoming obsolete at apex, 

 intervals flat rugosely punctured. Body beneath black, moderately shining 

 rather densely i)unctulate and sparsely pubescent. Legs black. Length .28 

 inch : 7 mm. 



The antennte arc longer than half the length of bi)dj. The elytra 

 scarcely longer than twice the thorax while the litter is but little 

 longer than the width at base. This species resembles in form a very 

 diminutive Ludhis afcr, Cand. 



'J'he unique before me was kindly loaned by Mr. Ulke, by whom it 

 ■was obtained from " California," without more precise locality. 



DRASTERIUS, Esch. 

 D. grandicollis, n. sp. pi. IV, fig. S. — Pale rufo-testaeeous, sub-opaque, sur- 

 face sparsely, clothed with short yellowish pubescence. Head with distant 

 coarse punctures, and fine punctuation densely placed in the intervals. Thorax 

 moderately convex and doubly punctured like the head, longer than broad and 

 narrower behind, sides strongly rounded, and with the hind angles parallel, 

 unicarinate, carina very close to margin. Scutellum very convex. Elytra 

 narrower than thorax, slightly broader behind the middle, at apex obtuse ; sur- 

 face moderately convex, finely striate, striae with coarse punctures ;_intorvals 

 flat with few sparsely placed fine punctures. Under surface punctured as 

 above, "^sparsely iJubescent. Legs somewhat paler. Tarsi siini)le. Length .24 

 inch ; 6 mm. 



This species may be known among our Drasferinx, by the'^double 

 punctuation of the thorax. The thorax is unusually large and with 

 the head nearly equals the area of the elytra. The sides of the 

 thorax are strongly rounded and the hind angles project backwards 

 with their outer margins parallel. The carina is strong and placed 

 close to the margin so that when seen from above the hind angles ap- 

 pear not to be carinate. According to the classification of Candeze 

 this species should be referred to IJeteroderes, a genus founded on the 

 peculiar surface sculpture, to the exclusion of more important organic 

 characters and therefore like Aeolus rather heterogeneous. 



One specimen in the cabinet of Dr. ]jeconte with no special desig- 

 nation of locality except California. 



D. marginicollis, n.sp.— Pioeous black, moderately shining, thorax piceo-testa- 

 ceous with very narrow space at side, and large discal spot piceous black, an- 

 tennae and legs testaceous. Surface sparsely clothed with yellowish hairs. 

 Head and thorax coarsely punctured the former more densely. Thorax slightly 

 longer than broad, sides moderately rounded and gradually narrowing in front, 

 hind angles acute carinate and prolonged backwards; disc moderately convex. 

 Elytra as broad as thorax feebly narrowed behind, surface moderately convex.
