NORTH AMERICAN COLEOPTERA. 20 



Utah ; quite different from our other species by the coarsely sculptured 

 thorax, which has also four shallow discoidal impressions. The third 

 joint of the antennae is a little longer than the fourth, whereby it differs 

 from Trirhabda, which it greatly resembles in form. 



HYPOL,AMPSIS Clark. 



H. gllttatilS. — Fuscous, densely clothed with fine short pubescence, legs and 

 elytra paler, the latter are twice as wide as the prothorax, impressed behind the 

 base ; strife well impressed finely punctured, each with three dark spots, the first 

 and third near the suture. Prothorax a little wider than long, alutaceous. Length 

 2 mm. 



Louisiana, Mr. A. C. Reisig; easily distinguished from H. Mellyi by 

 the wider, spotted elytra. 



CAEPORIS Clark. 



C liauula. — Greenish or bluish, bronzed. Antennae and legs fusco- testaceous, 

 the former with a very deep transverse impression near the base, the latter finely 

 but strongly punctured. Length 1-5 ram. 



South Carolina, Zimmerraann ; Texas, Schwarz. To this genus is 

 also referable Haltica Burgessi Crotch. They resemble, in miniature, 

 Haltica (Graptodera). 



DIRC.£A Muls. 



D. Riversi. —Cuneiform, less arched than usual, piceous, very finely and 

 densely punctulate, finely inconspicuously pubescent. Head convex, not im- 

 pressed. Prothorax as long as wide, narrowed almost from the base to the apex, 

 which is only half as wide as the base; sides not strongly rounded, hind angles 

 rectangular not sharply defined, base scarcely sinuate, feebly depressed transversely 

 in front of the base. Elytra not striate, with faint traces of two or three obsolete 

 elevated lines. Beneath colored and punctured as above; last joint as long as the 

 two preceding, but not much wider; third antennal joint as long as the two pre- 

 ceding, slightly shorter than the fourth. Length 11 mm. 



Collected at Sylvania, Sonoma Co., Cala., by Messrs. Rivers and Rick- 

 secker, in a decayed Madrone stump. This is the first appearance of the 

 group Dircaeae on our Pacific slope. 



ACRISIUS Desbr. 



On further examination of the insect which I referred to this genus 

 (Class. Col. 473), it seems to be distinct by the 3d and 4th ventral seg- 

 ments being of usual length. I cannot say at present to what genus it 

 should be placed. 



PACHYLOBIUS Lee. 



P. picivorus Germ. A typical specimen from the Dejeanian col- 

 lection kindly sent me by Mr. Roelofs shows that Hylohins stupidus Boh. 

 is the same species.
