 Length .48 inch ; 12 mm. 



Occurs at Enterprise, Fk)rida.

Dark brown or ]iiceous, moderately shining, the pubescence short, 

 sparse and indistinct. Similar in form to lituratus. Length .82 — .44 

 inch ; 8 — 11 mm. 



In this species the punctuation of tlie thorax is coarser than in any 

 other, although })reserving its simple and distinct character. On 

 the elytra the punctuation at base is somewhat intermixed, but not 

 to the extent observed in lituratus. 



Occurs in California, Sylvania. A number of specimens have 



been sent me by Mr. Rivers, the males three times more numerous 



than the females. 



H. bicinctiis n. sp. — Elougate. scarcely narrowed behind, moderately con- 

 vex, pioeous, niod(M-ately shining, very finely and sparsely pubescent, thorax 

 margined at base and apex with yellow, elytra with two yellow bands. An- 

 tennre slender, piceo-testaceous. Head vertical, not visible from above, densely 

 and finely punctured. Thorax not longer than wide, narrower in front, sides 

 regularly arcuate, base truncate and slightly narrower, siirfa<te moderately 

 densely and finely punctured, the basal impressions absent. Elytra finely and 

 closely punctate, the punctures less distinct toward the apex, color pioeous, a 

 broad yellow band on each elytron arcuate, convex in front, not reaching the 

 suture, one-third from base, a second narrow sigmoid band one-third from apex 

 ci'ossing thfe suture. Body beneath finely, but moderately punctate. Legs 

 brownish. Length .14 inch; 3. .5 mm. 



This species is the smallest known to me. It is the second of the 

 group discovered on the Pacific coast, and is rather of the tyj)e of 

 some of the European species. The lateral margin of the thorax is 

 distinct near the base only, and the marginal line does not extend in 

 front of the middle. This structure is also observed in the two pre- 

 ceding species. 



Occurs at Sylvania, California. L. E. Ricksecker.

 ately shining, sparsely pubescent. Antennae uniformly brown. Thorax with 

 apical border pale, surface moderately closely and finely x»unctate, not rugulose, 

 the marginal line entire. Elytra moderately closely punctate, somewhat smoother 

 posteriorly, the punctures near the base unequal, color brown, with a yellow spot 

 behind the humeri somewhat in shape like the letter H with the transverse bar 

 broad, posteriorly a sinuous band one-third from apex interrupted at the suture. 

 Body beneath densely and finely punctured, the abdomen similarly punctured in 

 the sexes. Length .30 — .44 inch ; 7.5 — 11 mm.
