40 GEO. H. HORN. M. D. 



H. Ulllerii Horn. — Form rather slender, rufo-testaceous, moderately shining, 

 si^arsely clothed with short yellowi.sh hairs. Antennae slender, half the length 

 of the body. Head convex, rather coarsely and closely punctured in front. Thorax 

 longer than wide, apex distinctly narro\\ er than base, sides moderately arcuate, 

 hind angles not divergent, basal plicse small but distinct, disc convex, punctuation 

 fine, not dense and uniform in degree. Elytra as wide at base as the thorax, 

 humeri distinct, sides gradually narrowing from the humeri to the apex, moder- 

 ately deeply striate, strife coarsely punctured, intervals slightly convex at base, 

 near apex costiform, the intervals 2-3-5-7-9 entire and more elevated, the surface 

 sparsely punctulate with a single series on each of somewhat larger punctures. 

 Body beneath shining, not closely punctulate, the punctures intermixed but not 

 conspicuously difierent. Claws cleft at tip, the tooth being very near the apex. 

 Length .24 inch ; 6 mm. 



This species is related to a small group associated by Candeze iu his 

 synoptic table (Elat. iii, p. 246) consisting of exoletus parmeiioides, at- 

 tenuatus and acutipennis, all of which occur on the Pacific slope of South 

 America. Of these exoletns is known to me by a type sent by Dr. Can- 

 deze in which I find the claws as stated above. There is, however, no 

 mention of this character in any of the descriptions but which is so evi- 

 dent as to indicate the propriety of a division of the genus into three 

 series instead of two. It is possible that some other species without 

 costiform intervals should be included in this third series. 



Occurs in Florida and Georgia. 



H. mitis n. sp. — Pale rufo-testaceous, moderately shining, sparsely clothed 

 with short cinereous pubescence. Antennse slender, extending beyond the hind 

 angles of the thorax. Head not closely punctate, vertex with a short longitudinal 

 impression each side. Thorax scarcelj' longer than wide, apex scarcely narrower 

 than base, sides feebly arcuate, disc convex, with very indistinct coarse and fine 

 punctuation not closely placed, basal plicte very small. Elytra slightly wider than 

 the thorax, humeri distinct, sides graduall}^ narrowing to base, disc striate, the 

 striae coarsely punctured, becoming rapidly finer to apex, intervals slightly convex 

 at base, flat at apex, sparsely punctulate. Body beneath closely finely punctulate 

 with coarse punctures intermixed, the punctuation finer on the abdomen than on 

 the sides of the prothorax beneath. Claws cleft at tip. Length .24 incli ; 6 mm. 



Easily distinguished from either of the pi'ecediug species by its nearly 

 square thoi'ax and the flat interstices at apex.
