DERMESTID/E 185 



minutely, loosely punctate, the ocellus prominent and well developed; 

 eyes prominent, the antennae very pale throughout, the last joint not 

 at all darker, long, parallel and apically obtuse; prothorax barely twice 

 as wide as long, the sides strongly converging and evenly arcuate from 

 base to apex; basal lobe moderate, prominent; surface broadly, feebly 

 impressed at base at each side of the middle; punctures minute and very 

 remote, rather less sparse and somewhat stronger near the sides; scutellum 

 triangular as usual; elytra scarcely one-half longer than wide, as wide as 

 the prothorax and fully three times as long, parallel, rounding in about 

 apical third, each apex somewhat broadly rounded; punctures minute and 

 sparse throughout, the black hairs long and bristling; legs slender; hind 

 tarsi fully as long as the tibiae. Length (c?) 3.8 mm.; width 2.0 mm. 

 New Mexico (Jemez Springs), -Woodgate. 



There is no species described thus far that seems to come any- 

 where near this; it is notably distinct because of the sparse erect 

 blackish hairs, and also the sparse sculpture and vestiture of the 

 under surface. The epipleura are flat as usual, but only extend 

 through basal third of the elytra. 



Trogoderma Latr. 



This is a large genus, particularly in the neostibarctic faunal 

 regions. The various species sometimes resemble each other rather 

 closely, but fortunately the eyes and male antennae furnish very 

 convenient and positive means of segregating them into groups, 

 within which the species may generally be easily recognized by 

 their form, sculpture and ornamentation. Obsolescent Csy., de- 

 scribed from a single female from an unrecorded locality, I have 

 since found at St. Louis, Missouri; it comes near inclusa Lee., but 

 differs in its smaller average size and distinctly more slender form. 

 The considerable number of undescribed species which have accu- 

 mulated since my review of the genus may be known as follows : 



Eyes not sinuate; antenna (cf) strongly serrate, joints three and four 



subequal. 



Trogoderma procera n. sp. Form elongate-oval, strongly convex, 

 shining, black, the elytra with transverse, sinuous and very irregular 

 rufous bands, the one at the middle at an unusually long distance from 

 the next posterior, which is the second from the tip and close to the apical, 

 the bands having ashy to yellowish pubescence, the general pubescence 

 short and fuscous; head two-fifths as wide as the prothorax, finely, rather 

 sparsely but deeply punctate, the eyes strongly setose; antennae ( 9 ) short, 

 with the usual 4-jointed club; prothorax slightly more than twice as wide 

 as long, the sides converging and evenly, rather strongly arcuate from
