230 GEO. H. HORN, M. D. 



This species has rather the habitus of a Chfetocnema than Haltica 

 in general. The nearly square thorax, together with the pale antennae 

 and legs will enable it to be distinguished from pollta and all the 

 others of the genus. 



Occurs from Massachusetts to Georgia. 



21. H. opulenta n. sp. — Oval, slightly oblong, moderately robust, cupreo- 

 violaceous. antennee and legs rufotestaceous. Anteunie half as long as the body, 

 joints 2-3-4 gradually increasing. Head shining, a few scattered, very fine 

 punctures, others coarser near the eyes, frontal carina moderately prominent, 

 tubercles small. Thorax nearly twice as wide at base as long, narrowed in front, 

 sides regularly arcuate, margin extremely narrow, slightly thickened at the 

 front angles, disc convex, ante-basal impression almost entirely obliterated, 

 surface very finely, sparsely punctulate. Elytra not wider at base than the 

 thornx, humeri very broadly rounded, umbone feebly distinct, surface shining, 

 finely, not closely punctulate Body beneath piceous, without metallic lustre ; 

 abdomen sparsely punctate. Legs entirely rufotestaceous. Length .16 inch. ; 

 4 mm. 



Two female specimens only have been seen. The form is some- 

 what that of obliterata, but a little shorter, while the surface color is 

 that of some of the darker forms of carinata. 



The very feeble transverse impression of the thorax as well as the 

 form will serve to distinguish this species from any of those with 

 pale antennae and legs in our fauna. 



Occurs in southern Arizona. 



22. H. floridana n. sp. — Oval, depressed, moderately shining, head, thorax, 

 body beneath and legs reddish yellow, abdomen brown, elytra bluish green. 

 Anttnnge half as long as the body, rufotestaceous, the outer joints darker, joints 

 2-3-4 about equal in length. Head finely alutaceous, a few coarse punctures 

 near the eyes, frontal carina very obtuse, tubercles indistinct. Thorax one-half 

 wider than long, not narrower in front, sides feebly arcuate, anterior angles ob- 

 liquely truncate, disc feebly convex, ante basal impression very feeble, surface 

 finely alutaceous, sparsely, finely punctate, an oblique series of coarser punctures 

 7iear the front angles. Elytra not wider at base than the thorax, humeri ob- 

 liquely rounded, umbone scarcely prominent, smooth ; surface alutaceous, 

 sparsely, indistinctly, but relatively coarsely punctate, smoother near the apex. 

 Body beneath reddish yellow, metasternum rather coarsely punctate ; abdomen 

 brownish, sparsely punctate. Length .12 inch. ; 3 mm. 



A small species resembling at first sight some of the smaller forms 

 of Dison. collata. It is easily known among our species by its color. 

 The front angles of the thorax are more distinctly obliquely truncate 

 than in any other in our fauna. 



Collected at Biscayne, Florida, by E. A. Schwarz, to whom I am 

 indebted for the female in my possession.
