AMERICAN COLEOPTERA. 7!l 



ACMSODERA, Esch. 



A. quadrivittata, n. sp. 



^Similar in form to A. tiihidus and agrees with that species in the 

 absence of any transverse carina and marginal groove to the last abdo- 

 minal segment, differing in the following particular : — 



Thorax slightly more elongate, median sulcus more distinct. Elytra striat*', 

 striae coarsely punctured, intervals flat or feebly convex, and with a single 

 row of fine punctures, each bearing a very short yellowish hair; color piceous, 

 with two yellow strijjcs on each elytron, the inner occupying the third, fourth 

 and fifth intervals, the outer the ninth and tenth, the two stripes united at 

 apex. Body beneath black, with a slight greenish tinge, sparsely punctured, 

 each puncture bearing a short pale hair. Length .22 inch ; 5.5 mm. 



One specimen collected in Utah by Dr. Palmer, placed at my dis- 

 posal by Mr. Townend Glover. 



CORYMBITES, Latr. 

 C. longicornis, n. sp. — Form slender, elongate. Head piceous, coarsely 

 punctured; antennae ^ equalling four-fifths the length of body. Thorax moder- 

 ately convex, piceous, shining, coarsely not very densely punctured, more 

 densely at the hind angles ; form elongate, nearly twice as broad as long, sides 

 straight, slightly converging in front, hind angles slightly divergent, sub- 

 acute and tipped with yellow. Elytra elongate, slightly narrower behind, 

 moderately convex and shining, brownish, with broad discal yellow stripe ; 

 surface moderately striate, striae punctured, intervals moderately convex, 

 punctured and more rugose at scutellar region. Body beneath piceous, abdo- 

 men and legs paler. Entire surface very sparsely clothed with greyish hairs, 

 rather dense beneath. Length .54 inch ; 13.5 mm. 



Allied to C. hivlttatus, Mels., differing in the much less dens!e!y 

 puuctured and more shining thorax, and the less acute and less diver- 

 gent hind angles. The antennae are also much longer. 



For the unique in my cabinet I am indebted to Mr. Townend 

 Glover, of Washington. Collected by Dr. Parry in the mountains of 

 North Carolina. 



COLLOPS, Erichs. 



Uur species of C'oUops have become quite numerous and it has been 

 thought useful to present to the American students the results of a 

 short study of our species, and without desiring to prolong the present 

 paper unnecessarily, neither bibliography or description of each species 

 will be given except when found necessary to carry out the object of 

 the present sketch which is to present a table by which our species 

 may be readily determined without recourse to the various publications 

 in which they are now scattered. 



In examining the antennae of our largest species (valuhis) there 

 will be found a curious articulated appendage arising from near the
