TYLOPTERUS n. g. 



This genus is established upon two small species from Texas, clothed 

 with remarkably dense sericeous pubescence, and having small tufts of hair 

 and very prominent elytral callus. The beak is slender and curved ; the 

 eyes large; the front narrow (about one-third as wide as the beak). The 

 antennse are inserted about one-fourth from the end of the beak, slender; the 

 scape reaches the eyes; funiculus 7-jointed, first joint as long as the two fol. 

 lowing; second joint a little longer than the third; club elongate-oval, annu- 

 lated. Prothorax wider than long, narrowed in front, broadly rounded on 

 the sides, convex. Elytra suddenly more than one-third wider than the 

 prothorax, humeri prominent, "elevated, rounded, sides converging a little 

 behind; posterior callus very prominent. Ventral segments subequal, ex- 

 cept the fifth, which is as long as the two preceding united; first ventral 

 suture straight, others angulated at the sides, but the second more so than 

 the third, so that the angles of the second segment project over the third 

 nearly to the fourth segment. Pygidium of 9 nearly covered by the elytra; 

 anal segment of J^ large, deflexed, and convex. Legs rather long, thighs 

 clavate, not armed, front tibite longer, more slender, and slightly sinuate in 

 (^■, terminal hook very small; claws with a large tooth near the tip. 



1. T. pallidus, n. sp. 



Densely clothed with pale ashy hair, with golden reflexions, which con- 

 ceals the sculpture; front channeled. Elytra with the posterior callus in the 

 form of a large obtuse tubercle, causing the declivity to appear broadly con- 

 cave; marked with two irregular transverse bands of brown hair, the pos- 

 terior one in front of the callus, and nan-owed at the suture; the front one 

 commencing at the middle on the sides, and running obliquely backwards 

 to the suture, where there is a narrow tuft of black hair occupying the first 

 interspace for one seventh of its length; small pencils of black hair are also 

 seen on the third, fifth and seventh interspaces where the bands cross them; 

 there is also a little tuft on the third interspace near the base. Antenna; 

 and legs ferruginous yellow. Beak naked, polished, sparsely punctured at 

 the base. Length 4 mm.; .16 inch. 



One 9. Texas, given me by Mr. W. Jiilich. 



2. T. varius, n. sp. 



Pubescence beneath white; above on head, prothorax and base of elytra 

 brownish -yellow; dorsal line of prothorax and scutellum, and main surface 

 of elytra pale cinereous, suture mostly yellow; two broad dark brown bands 

 as in the preceding, but separated only by a narrow oblique cinereous line; 

 interspaces with scattered small dots of longer white hairs; posterior callus
