LeConte as i — B (Rhynchophora, p. 239), and by the 

 moderate length of beak, which is strongly striate, and 

 by the protuberant mesosternum, is allied to posticatiis. 

 It resembles the latter species in the vestiture, and differs 

 especially in the very coarse sculpture of the thorax, 

 which approaches that of cribricollis. 

 One specimen. San Jose del Cabo. 



CONOTRACHELUS ECHINATUS n. sp. 



Form of erinaceus, piceous, clothed with luteous and 

 dark brown scales, indiscriminately intermixed on the 

 thorax, on the elytra at declivity an indefinite band of the 

 paler color, on the intervals are moderately long black 

 hairs, in the punctures of the striae a slender pale hair. 

 Beak longer than head and thorax, sulcate at the sides, 

 in front rather densely scaly and with erect hairs, antennae 

 inserted close to the tip. Thorax wider than long, not 

 greatly constricted in front, sides feebly arcuate, disc con- 

 vex, coarsely, deeply and not closely punctate. Elytra 

 nearly twice as wide at base as the thorax, one-third longer 

 than wide, humeri prominent but not dentiform, disc striate, 

 stri« punctate, intervals flat. Abdomen coarsely and 

 deeply punctate. Legs piceous, tibi« and tarsi paler, 

 densely scaly and with whitish hairs. Femora not toothed. 

 Claws cleft. Length, .10 inch; 2.5 mm. 



This species belongs to a small group containing but 

 two species, characterized by the cleft claws and the 

 presence of erect setae on the intervals. It differs from 

 either of the two at present known by the style of vesti- 

 ture, the longer erect hairs and the entire absence of 

 femoral tooth. As is usual with species of bicolored 

 scales the surface is variegated in color and not purely 

 piceous. 



Two specimens. Southern Arizona.
