New Genera and Species of Neotropical Curc^ihmiidae. 195 



excavated ; the epistome with an angulated margin. Antennae 

 with the scape slightly exceeding the hind margin of the eye, stout, 

 gradually dilated from base to apex, clothed with very dense narrow 

 overlapping scales, and set with stout suberect setae; the funicle 

 with joint 2 slightly longer than 1, 3 distinctly longer than 4, and 

 4-7 subequal and a little longer than broad. Prothorax as long as 

 broad, widest at the base and slightly' narrowing anteriorly, the 

 sides almost straight; the dorsum very coarsely and remotely 

 punctate and somewhat wrinkled, but without any flattening; 

 the anterior margin sublobate behind the eyes. Scuiellum elongate 

 pear-shaped, broadest behind the middle, with a deep transvei'se 

 impression before the middle, and densely covered wth narrow- 

 overlapping scales. Ehjira broadly ovate, the shoulders very 

 prominent and almost rectangular, the sides not sinuate behind the 

 shoulders but gradually narrowing posteriorly, the apices each 

 produced into a long sharp process ; the dorsal outline rising for a 

 very short distance from the base, then flat to the top of the declivity, 

 v/hich has a slope of 60° ; the striae shallow and some of them rather 

 irregular, the punctures in stria 1 smaller and more numerous than 

 those in 2, stria 4 strongly sinuate before the middle, two accessory 

 stiiae between 3 and 4 behind the middle, and stria 5 irregular 

 and subinterrupted not far from the base ; interval 3 sharply carinatc, 

 without tubercles and produced at the top of the declivity into a 

 long sharp horizontal process like that at the apex; ints. 5 and 7 

 also carinate, the former not rcachmg the base but curving outwards 

 to join 7 at some distance behind the shoulder and ending in a small 

 tubercle on the declivity; the white scales broad and strongly 

 overlapping, the brown ones narrower; the setae small, irregular 

 and recumbent, being much longer and slightlj^ raised on the apical 

 processes. Legs with rather stout raised white setae ; the tibiae not 

 denticulate internally, the apical mucros comparatively short and 

 concealed ; the second joint of the front tarsi a little broader than 

 long, the claws with a lateral seta. 



Length, 15-20 mm. ; breadth, 5-5-8 mm. 



Brazil : S. Paulo. 



Described from six specimens. 



Very similar in both form and colouring to C. niveus F., 

 but in that species the head is much less constricted behind 

 the eyes ; the front margin of the prothorax is not lobate 

 laterally; on the elytra the raised intervals all bear small 

 tubercles and interval 5 is continued normally to the base, 

 the striae are all quite regular and there are no accessory 

 ones, and the setae are distinctly finer and longer.
