longer than the others, joints 3-7 obconical ; clul) oval. Eyes roimd. 

 Thorax cyUndrical, sides feebly arcuate, narrowed in front. Scutelluninot 

 visible. Elytra broadlj^ oval, convex. Intercoxal process broad, truncate. 

 Second segment of abdomen as long as the two following united, separated 

 from the first by a strongly arcuate suture. Tibiae not inucronate. Claws 

 connate. Body scaly and with erect setoe. 



This genus is closely allied to Peritelas. It differs at first sight in tlie 

 vestiture of the body. The scrobes are much shorter and very decidedly 

 convergent above, the alee not divergent, antennae, especially the scape, 

 shorter. The genus is also allied to Mylacus in which, however, the sur- 

 face is pubescent. 



Two species are known to me, both Western. 



T. inornata, n. sp. 



Form oval, moderately robust. Head and rostrum longer than the 

 thorax, surface sparsely punctured and not densely scaly. Antennae rufo- 

 testaceous, sparsely llair}^ Thorax cylindrical slightly wider than long, 

 apex and base truncate, sides feebly arcuate, slightly narrower in front and 

 very feebly constricted at the. sides behind the apex ; surface coarsely and 

 deeply punctured, sparsely scalj^ and with erect hairs. Elytra nearly three 

 times as long as the thorax, oval, slightly inflated, Avitli rows of moderately 

 coaree, closely placed punctures, intervals flat, moderately densely scaly 

 and with a row of short black erect setae. Body beneath sparsely scaly, 

 abdomen sparsely punctured and very sparsely hairy. Legs rufo-testa- 

 ceous or slightly darker, sparsely hairy. Length .14 inch ; 3.5 mm. 



The scales covering the body are of pearly lustre and very easily re- 

 moved, and beneath them the surface is black and shining. The elytra 

 are not striate, the punctures merely form regular rows and are of large 

 size and rather closely placed. In some specimens of narrower form, and 

 which are probably males, the striie of the disc are slightly impressed near 

 the base. Specimens occur of slightly larger and smaller size than the 

 measurement given. 



Occurs from northern California to Utah. , 



T. simulator, n. sp. 



Form oval, moderately robust. Head and rostrum longer than the 

 thorax, surface very densely scaly and with very short set*. Antennae 

 pale rufous, slightly hairy, scape sparsely scaly. Thorax wider than long, 

 sub-cylindrical, slightly narrowed in front, base and apex truncate, sides 

 feebly arcuate, modertely convex, surface coarsely and rather deeply jDunc- 

 tured, densely scaly, scales cinereous and with a broad median space 

 darker. Elytra oval, slightly inflated, surfiice finely striate and with 

 rather small punctures distantly placed, intervals flat, densely covered with 

 cinereous scales, with fuscous spots irregularly placed, a sinuous baud of 

 the same color at the posterior declivity and with very short erect setae in 

 a single row on each interval. Body beneath moderately densely scaly. 

 Legs rufous, moderately densely seal 3' and with short hairs. Length .13 

 inch ; 3 mm.
