CRIOPROSOPUS. 75 
sexes similarly grooved joints. There is no difference of colour between the sexes of 
C. rimosus. 
5. Crioprosopus basileus. 
Oblongus, valde elongatus, rufo-castaneus, infra ,griseo-sericeus, elytris splendide viridi-eneis subtilissime 
sparsim punctatis, hic illic transverse rugatis; thorace valde transverso, lateribus post medium tubere 
magno subconico, dorso creberrime punctato, linea lata dorsali levi, antice dilatata et post dilatationem 
iterum angustata, juxta basin dilatata; mesosterno declivi.

Hab. Mexico, Oaxaca (Fenochio). 
_ Very closely allied to C. iridescens?. It differs very little in colour, the red under 
surface and femora only being of a duller, castaneous hue, scarcely differing from the 
slightly darker tibize and sides of the mesosternum, and the elytra being greener and less 
golden, as well as very much less punctured and wrinkled. In form there are well- 
marked and important differences in the thorax and mesosternum. The sides of the 
former instead of being obtusely rounded are produced into a large and nearly conical 
tubercle ; and the smooth dorsal line is narrowed instead of widened (as well described by 
White) behind the anterior dilatation. The mesosternum (between the legs) gradually 
slopes forward, and is not produced into a large tubercle with vertical anterior face as 
in C. iridescens. 
6. Crioprosopus tricolor. 
Callona tricolor, Waterhouse, Trans. Ent. Soc. 11. p. 228 (1840)}. 
Hab. Panama, Obispo (Salvin).— VENEZUELA ? 
The specimen taken by Mr. Salvin differs from that described by Waterhouse only 
by the amount of red colour on the sides and under surface of the thorax, the separate 
spots, as described, being united into a large lateral spot reaching nearly to the front 
margin and prolonged in a ring underneath the prothorax. The mesosternum is pro- 
duced: into a conical projecting tubercle. 
7. Crioprosopus thoracicus. 
Stenaspis thoracicus, White, Cat. Col. Long. B. M. i. p. 78°. 
Hab. Honpvras (Dyson). 
According to White, perhaps only a variety of C. tricolor. 
8. Crioprosopus rutilans. (Tab. VI. fig. 3.) 
Crioprosopus rutilans, Bates, Trans. Ent. Soc. 1869, p. 384, 2*, et 1872, p. 192. 
Hab. Nicaraaua, Chontales (Belt 1, Janson). 
In the private collection of Mr. Belt (since acquired by Mr. Godman) there is a male 
specimen of this species. It is of the same colour as the female, except the narrower
