AMERICAN COLEOPTERA. HI 



The genus Trophimm is the representative in our fauna of the 

 European Troghps and Homceodipnus, but resembles more nearly 

 Cephalagonia Wollast. as well in form as in most of its characters, it 

 differs from the latter, however, in the third joint of the antenna? 

 being shorter than the fourth and the first tarsal joint long. This 

 genus and the following are the only ones with 11-jointed antenna?, 

 in which the anterior tarsi differ in the sexes in the number of their 

 joints. 



TEMtf OPSOPHUS, n. g. 

 Head short obtuse in front. Eyes prominent. Antenna? nearly as 

 long as the entire body, eleven-jointed; first joint longer than the two 

 following together, stout, very slender at base 

 and with a short process from the anterior 

 margin projecting inwardly; joints 2-10 equal, 

 joint eleven longer than the tenth ; insertion 

 at the anterior margin of front. Maxillary 

 palpi moderately long, first joint slender, sec- 

 ond globular, emarginate on the proximal 

 side to receive the third which is triaugular 

 and thick. Anterior tarsi four-jointed in the 

 male. Elytra entire. 



This represents in our fttuna the genus 

 Colotes of Europe, from which it may readily 

 be distinguished by the form of the basal 

 joint of the antennae and the form of the 

 palpi. 



T. bimaculatus, n. sp. — Piceous, shining. 

 Head piceous, anterior margin of front yellowish, 

 vertex with slight linear impression, surface sparselv 

 punctulate and finely alutaceous. Antennae pale yellowish, tip darker. Thorax 

 oval, in front broadly rounded, apex truncate, sides rounded in front and con- 

 verging to apex, color piceous, shining, apex paler, surface punctulate and 

 finely alutaceous. Elytra piceous with large yellow spot behind the humerus 

 joining the margin which is also narrowly margined with yellow, apex pale 

 testaceous gradually joining the darker color of the rest of the surface; form 

 oval, rapidly widening behind; surface rather coarsely but sparsely punctured. 

 Body beneath piceous. Legs pale brownish- testaceous, femora at base paler. 

 Body winged. Length .08 inch; 2 mm. 



The elytra are broadest near the apical three-fourths and are 

 nearly twice as broad at this point as at base. The thorax resembles 

 in form that of Endeodes. 



One specimen % in the cabinet of Mr. H. Ulke from Louisiana.
