124 GEO. H. HORN, M. D. 



Very distinct by the characters given in the table and is more 

 sleuder than is usual in the broad headed group of the genus. 

 Its geographical distribution corresponds with the preceding. 



A. melaiiopterus, Erichs. (Anthocomus),'Entoraog.i.,p. 110. — Head, tho- 

 rax and abdomen pale rufous. Elytra and body beneath black. Legs pale 

 rufous, hind femora at tip piceous. Surface shining and scarcely pubescent. 

 Length .10 inch; 2.5 mm. 



A very distinct species of which I have seen but one specimen in 

 the Cabinet of Mr. Ulke. 



Occurs in Tennessee. 



A. liumeralis, Lee. New Species, p. 94. — Pale rufous. Antennae brown- 

 ish at tip. Elytra with small humeral black spot. Pectus piceous. Anterior 

 and middle legs pale rufous, hind legs piceo-testaceous. Length .12 inch ; 

 3 mm. 



The above characters will readily distinguish this from any known 

 species. 



One specimen from Illinois. 



A. parallelus, n. sp. — Form parallel, sub-cylindrical, sparsely pubes- 

 cent. Head rufous, front slightly impressed, shining. Antennae piceous, 

 under side of basal joints paler. Thorax rufous with small black spot at mid- 

 dle of anterior margin, one-third broader than long, sides and hind angles 

 broadly rounded, surface shining. Scutellum rufous. Elytra parallel, scarcely 

 broader at base than thorax, surface sub-opaque, rufous, with humeral and sub- 

 apical spot black. Body beneath rufous, metasternum piceous. Legs black, 

 under side of anterior and base of hinder femora pale testaceous. Length .12 

 inch; 3 mm. 



This species is readily known by its coloration and its parallel form, 

 all our other species being more or less dilated behind. 



One specimen collected in central Texas, by Mr. Belfrage. 



A. I*ettiti, n. sp. — Head rufous shining, front slightly impressed. An- 

 tennae piceous, basal joints paler. Thorax rufous, shining, broader than Ions;, 

 sides and base conjointly arcuate. Elytra broader at base than thorax, dilated 

 behind, rufous, shining and with humeral and large apical spot black. Body 

 beneath pale rufous, metasternum black. Legs pale rufo-testaceous, hind 

 femora, except at tips, piceous. Length .08 inch; 2 mm. 



A species recalling trimaculatus. The elytra are more black than 

 rufous and might be described as "black with suture, apical margin 

 and transverse band in front of middle rufous." 



It may be known from the preceding species by the more shining 

 surface and the elytra dilated behind as is usual in the genus. 



One specimen in my cabinet from Canada, presented by Mr. John- 

 son Pettit.
