whitish. E3"es very prominent, entire. Antennse brown, 8-jointed ; first 

 joint is large, globular, 2-G small, longer than wide, 7-8 forming the club, 

 longer than wide, equal, together not making up quite one-half the entire 

 antenna. Thorax covered with scales, brown at disc, yellow and white at 

 the sides and base. Scutellum hardly seen. Elytra brown, covered, not 

 densely, with brown and white scales, marked by three irregular indistinct 

 siuuous bands and humeral spot of white. Body beneath brown, covered 

 with small, triangular, cinereous scales, a row of black spots on each side 

 of abdomen, no naked hollows on the first segment, and a faint median 

 black spot on the last. Legs brown, femora clothed with whitish scales. 

 Length .OG-.IO inch ; 1.5^-2.5 mm. (Fig. 72.) 



This species can be recognized by the entire eye.s, the 8-jointed antennae, 

 and small triangular sparse scales. 



A. claviger Er. Ovate, convex, black, clothed Avith black, moderately 

 large, triangular scales. Elytra ornamented with three faint, sinuous 

 bands and humeral spot of j'ellow scales. Head black, coarsely punctate, 

 scales black and yellowish. Eyes prominent, entire. Antennae 5-jointed ; 

 joints 1-2 large, globular, sub-equal, 3-4 very small and compressed, the 

 last more than three times as long as the other joints united ; rufous, last 

 joint darker. Thorax coarsely punctate, scales black at middle, yellow at 

 sides. Elytra black and piceous, very coarsely punctured, clothed with 

 black scales and with three equally separated, indistinct, interrupted, sin- 

 uous bands, and humeral spot of small yelloAv scales. Body beneath 

 black, covered with small sparse cinereous scales. Legs rufous. Length 

 .07 inch; 3.7 mm. (Fig. 73.) 



The smallest, darkest, and least conspicuously ornamented of any of 

 our species. The distinguishing characters are the 5-jointed antennae' 

 with its 1 -jointed club, the entire eyes, the small sparse scales, and the 

 almost uniform jColor of the elytra. 



Occurs in' Pennsylvania. 



APSECTUS Lee. 



The one species upon which this genus is established, is the smallest" 

 form found among our DermesticlcB ; the head is wide, the epistoma short, 

 the ocellus distinct, the mouth parts protected by the prosternum. Eyes 

 very large, prominent, rounded, entire. Antennae as long as the thorax, 

 11-jointed, terminated by a slender, elongated, 3-jointed club. Thorax 

 twice as wide as long, sides flattened, lateral margins arcuate, hind angles 

 prominent ; base bisinuate, slightly lobed posteriorly at middle. Scutel- 

 lum quite large. Elytra as wide as long, sides regularly oval, apical angles 

 not separately rounded. Antennal fossae not sharply defined, sub-marginal. 

 Prosternum lobed in front, narrow, moderately long, produced behind 

 between the anterior coxaj, separating them w-idely, but broadly truncate 

 at tip, reaching the mesosternum which is short, three times as wide as 

 long and rounded in front. Mesocoxae very widely separated. Posterior
