302 G. II. HORN, M. D. 



obtuse not carinate ; surface convex, densely, finely and equally punctured, 

 basal impression moderate. Elytra as broad as thorax at base, gradually nar- 

 rowed to apex, surface striate, strioe punctured, intervals flat, densely and fine- 

 ly punctulate. Body beneath aeneous, more shining than the upper surface, 

 densely punctulate. Legs black with very distinct aeneous tinge. Claws not 

 toothed. Length .28 — .32 inch ; 7 — 8 mm. 



Two specimens collected in California, south of San Francisco. 

 Differs from all the species known to me by its bright aeneous lustre 

 and grey pubescence. The thorax although finely punctured is more 

 coarsely so than is usual in the genus or at least among our species. 



HOEISTONOTUS, Eand. 



H. definitus, n. sp. — Robust, sub-opaque, color variable from rufo-testaeeous 

 to brownish, surface rather densely clothed with yellowish pubescence, longer 

 on the head and thorax. Head coarsely punctured. Thorax longer than 

 broad, very convex, sides strongly rounded and near the hind angles feebly sin- 

 uate, angles short, acute ; surface punctured rather closely with minute punc- 

 tulations densely intermixed; lateral margin distinct in its posterior half. 

 Elytra as broad as thorax, sides feebly rounded, surface convex, rather deeply 

 striate, strife punctured; intervals flat, very sparsely punctulate. Body be- 

 neath very convex, more shining than the upper surface, sparsely punctulate 

 and pubescent, color similar to the upper surlace. Tarsal claws feebly dentate 

 at base. Length .30 — .32 inch; 7.5 — 8 mm. 



A very distinct species. The thorax is usually darker in color than 

 the elytra. 



Collected by myself in Owen's Valley, California. 



H. Uhlerii, n. sp. — Brownish or ferruginous, sparsely clothed with greyish 

 l)ube3cence. Head finely punctulate, antennce brownish testaceous sometimes 

 jialer. Thorax one-fourth longer than broad, slightly narrower in front; sides 

 anteriorly slightly arcuate, posteriorly straight subparallel and very feebly 

 sinuate in front of hind angles which are subacute ; surface moderately convex, 

 very finely punctulate. Elytra slightly broader at base than thorax and more 

 than twice as long, gradually attenuate behind ; surface deeply striate, stripe 

 punctured, intervals convex and costiforna at apex, the intervals 2 — 4 — fi more 

 strongly elevated and the eighth still more so. Body beneath densely punctu- 

 late an<l clothed with greyish pubescence. Legs testaceous. Outer angles of 

 coxal plate broadly rounded. Length .2-1 — ,28 inch; 6 — 7 mm. 



Two varieties occur. Three specimens from Florida are smaller 

 paler and more shining. Two from Maryland are darker, the thorax 

 being darker than the elytra, less shining and larger. I cannot find 

 any other characters than these on which to separate them and these I 

 deem insufficient. 



Through the kindness of Dr. Candcze, I have been enabled to com- 

 pare this species with 11. exoletus. The principal differences are 

 found in the greater elevation of the intervals, especially the eighth,
