Testaceous, more or less clouded, or marked with black, or 

 piceous black. Head conically produced, and recurved like 

 a sow's snout ; rugosely punctate, ^the edges and front with 

 a reflexed black margin ; two tubercules, united by a curved 

 ridge between the eyes, making a slight separation between 

 the front and back of the head ; these tubercules and ridges, 

 the vertex and the reflexed margins of the head, are all more 

 or less distinctly marked with black or dark brown. Mandibles 

 black, protruding, tapering, recurved ; but not reaching so far 

 as the end of the snout. Palpi and antennae blackish-brown ; 

 antennae with ten joints. Thorax, with two or three depres- 

 sions or irregularities in the surface on each side of the disk ; 

 more or less clouded with black or dark brown, often inclosing 

 two testaceous spaces on the disk ; smooth and shining sparingly 

 punctate, at its widest narrower than the elytra ; when seen 

 in profile, not rising in a curve from the base, but proceeding 

 straight forward, and rounding down towards the apex ; mar- 

 gin with a raised edging along the sides in front and a short 

 part of the base, next the angles, but not on the middle of 

 the base, which is slightly bisinuate ; sides rounded, slightly 

 oblique behind, widest a little before the middle, rapidly con- 

 tracted in front ; anterior angles slightly projecting ; poste- 

 rior angles rounded. Scutellum triangular ; lateral sides very 

 slightly sinuate ; sparingly and faintly punctate ; testaceous, 

 with a larger or smaller black or dark patch, which is more 

 or less interrupted with testaceous. Elytra shining, of rather 

 a coarse texture, more or less clouded with black, the ex- 

 tent of the black varying much. The testaceous portions 

 are usually a space around the scutellum, extending a short 

 distance along the suture and along the base, sending down 

 for a short distance about the middle an arm parallel to 



iii., 399), who disallows this genus, and retains it as a portion of the Genus 

 Cyclocephala, I agree with Erichson in holding that the characters he has given ? 

 more especially the recurved mandibles, are sufficient to justify its being re- 

 tained as a distinct genus, although they may not be of equal value with those 

 of the great genus from which he has separated it.
