DERMESTID.E i8y 



Eyes not sinuate; antennae (c?) less serrate, the third joint very small. 



Trogoderma plagifera n. sp. Oblong, rather convex and moderately 

 shining, black, the elytra with the usual pattern of irregular pale lines 

 and spots, except that in fully anterior half the pale color is nearly solid 

 except near the sides, and also in two basal black spots on each; pu- 

 bescence coarse, abundant, ashy and fulvous on the pale areas, obscure 

 and finer on the black spots; head two-fifths as wide as the prothorax, 

 rather convex, the ocellus not very sharply defined, the sculpture con- 

 sisting of large shallow punctures, polygonally crowded throughout; 

 antennae (cT) rufous, moderately long, stout and serrate, the joints ec- 

 centrically joined, but scarcely so markedly so as in the preceding division; 

 joints five to eight gradually larger, transverse; prothorax not more than 

 twice as wide as the median length, the sides strongly converging but 

 only very slightly arcuate from base to apex; pubescence coarse, unevenly 

 and loosely condensed; basal lobe strong as usual, its surface feebly 

 impressed transversely; punctures fine but deep and rather close-set; 

 elytra fully as wide as the prothorax and not over three times as long, 

 parallel, very obtusely rounded at apex, the punctures small but strong 

 and rather close-set, not evidently larger than those of the prothorax; 

 under surface closely punctured, the sterna more strongly than the more 

 shining abdomen; hind tarsi (cf) but very little shorter than the tibiae. 

 Length (cf 1 9 ) 2.3-2.5 mm.; width 1.2-1.25 mm - Colorado (Boulder 

 Co.). Three examples. 



Rather more closely allied to oblongula Csy., from El Paso, Texas, 

 than to any other species known to me, though easily separable by 

 the more solidly pale elytra in anterior half, more elongate-oblong 

 elytra and less coarse, elongate or abundant erect pubescence of the 

 latter. The sculpture of the head is altogether different from that 

 of procera or parvula. 



Trogoderma cylindrella n. sp. Parallel, strongly and subcylindrically 

 convex, very small in size, rather shining, the elytra dull and solidly 

 ochraceous in color, each with a large rounded blackish spot just behind 

 the middle and truncated by the suture, and a smaller, more nubilous 

 dark spot near the scutellum; anterior parts and under surface black to 

 piceous, the legs pale; head (9) fully half as wide as the prothorax, 

 convex, the punctures coarse, shallow and umbilicate, close-set but not 

 crowded; antennae (9) short, with the usual 4-jointed club; prothorax 

 barely twice as wide as long, the converging sides from base to apex only 

 feebly arcuate; punctures very fine but deep and rather well separated; 

 pubescence slightly condensed unevenly; elytra as wide as the prothorax 

 and three times as long, parallel and straight at the sides, rapidly very 

 obtuse at apex; punctures relatively coarse and close-set, with the surface 

 somewhat rugose, having two to three times the diameter of the pronotal 

 punctures; pubescence coarse, suberect, not notably long or dense, 

 evenly ashy on the pale parts and blackish on the dark spots; under sur- 

 face shining, the pubescence rather sparse. Length (9) 1.8 mm.; 

 width 0.9 mm. New Mexico (Jemez Springs), Woodgate.
