width throughout; it is about equally broad at the distal ex- 

 tremity and in the region of the eyes, slightly contracted in the 

 space between the antennae and the eyes, and more distinctly 

 contracted behind : the eyes of moderate size, but little convex, 

 round, and placed nearly midway between the opposite extremities 

 of the head. On the fore part of the head is a faint longitudinal 

 groove, and there are some fine punctures scattered on this part : 

 the hinder part of the head is smooth. 



Thorax distinctly longer than broad ; about one-third shorter 

 than the elytra, but equalling the body in width. The posterior 

 half of this segment is nearly cylindrical, and exhibits a few in- 

 distinct longitudinal rugae, and some scattered punctures on the 

 upper surface. The fore half of the thorax is compressed, so that 

 the dorsal surface presents an obtuse keel, and on this keel are 

 two transverse indentations, as well as a longitudinal groove. 

 The hinder part of the keel is most raised, and forms a hump. 



Body nearly cylindrical, but the elytra are slightly depressed 

 on the fore part: they are crenato-striated. Near the apex of 

 the elytra the suture is raised. 



Femora and tibiae deep and compressed ; the hinder femora 

 long and stout, and swollen in the middle (vide wood-cut) ; the 

 tibiae equal in length to the femora, equally stout, and most broad 

 at the distal extremity. The hinder tarsi are likewise very stout. 



The antennae are equal to the thorax in length, moderately 

 thick at the base, and becoming gradually broader to the apex : 

 the nine basal joints are nearly spherical ; the three terminal 

 joints are distinctly larger than the rest and somewhat com- 

 pressed ; two of them present a nearly square outline, whilst the 

 last joint is longer than broad and somewhat pointed. 



This insect approaches to the species of Taphroderes in many 

 of its characters, but differs in having the head much broader in 

 front of the eyes, and more especially in the elongated form of 

 the hinder femora. On account of these differences, I have de- 

 scribed it under a new generic title ; and 1 may here observe, 

 that the insect described by Mr. Westwood under the name Ta- 

 jihroderes IVhitei, possessing all the essential characters of the 

 Ci/p/iagogus JVestwoodli, should be arranged under the same sec- 

 tional name. The former insect differs from the C. JVestwoodii in 

 having the thorax distinctly punctured, and in wanting the con- 

 striction in the middle of the hinder femora ; it is moreover much 

 smaller, and has the tip of the rostrum, as well as the legs and 

 antennae, pitchy red, whereas in the C IVeslrvoodii all these parts 

 are black.
