spots on abdomen are the characters upon wliich to rely for a correct 

 diagnosis. Dennestes mannerJieimi hoc., appears to be only a variety in 

 which the basal elytral spots are shorter and more confluent, while the 

 transverse spots at middle and apex are wider and more distinct. 

 Occurs in the "Western and Pacific States. 



D. fasciatuB Lee. Elongate, black, convex, quite densely clothed with 

 black and cinereous pubescence. Elytra with a moderateh'' broad sub- 

 basal band, fine transverse mottlings of cinereous pubescence. Head 

 moderately coarsely, densely punctate, pubescence semi-erect, dense, 

 variegated fulvous and black. Antennae piceous, club fuscous.. Thorax 

 very convex, lateral margins not visible from above, sides arcuate, densely 

 and finely punctate, only a very slight depression at the middle of the 

 base ; pubescence dense, variegated, brown, black and cinereous. Scutel- 

 lum covered with long, falvo-cinereous, recumbent hairs. Elytra finely 

 and densely punctate, strise hardly apparent, pubescence black, mar- 

 morated with small, cinereous, transverse spots ; a broad transverse band 

 which does not reach the base also cinereous. Body beneath clothed with 

 dense yellowish- white, recumbent pubescence, a single series of lateral 

 black spots on abdomen, last segment black, except three white spots at 

 base. Legs covered with dense brown hairs, femora annulated at middle. 

 Length .32 inch ; 8 mm. (Fig. 11.) 



No diflSculty will be encountered in recognizing this species ; the broad, 

 distinctly limited, transverse elytral cinereous band, which never attains 

 the base, is characteristic. 



Occurs in Colorado. 



D. murinus Linn. Elongate, black, clothed with fine black and cine- 

 reous pubescence. Elytra black, covered with marmorate black and cine- 

 reous hairs. Head densely and moderately coarsely punctate, clothed with 

 dense variegated hairs. Antennae piceous, club fuscous. Thorax very con- 

 vex in front, lateral margins not visible from above, sides arcuate ; finely 

 but densely punctate, a faint median basal depression, pubescence dense, 

 variegated, a small white spot at middle. Scutellum clothed with cin- 

 erous hairs. Elytra black, densely and finely punctate, strite indistinct, 

 marmorate with fine sparse black, and coarser cinereous pubescence, the 

 latter more dense at base. Body beneath black, clothed with long, dense, 

 whitish yellow pubescence, abdomen with a row of black spots on each 

 side, last segment black, marked with two white spots at base. Legs 

 brown, femora annulated at middle with white. Length .22 inch ; 8 mm. 

 (Figs. 12, 13.) 



This species is to be distinguished from tlie preceding by the irregularly 

 mottled cinereous and black pubescence on the elytra, there being no dis- 

 tinct basal or sub-basai band. Two varieties can be recognized. 



Variety a. In this the cinereous spots at the sides of the base of the 

 elytra are confluent, the entire basal half appearing yellowish-white, ex 

 cept some black marking near the suture. (Citiiinus Germ.)
