Longicornia of Mexico and Central America. 273 



Ilab. Panama, Cliiriqui {Tr'jtsch). 



Head black, with the front, the cheeks, a short vitta behind 

 each eye, and a median dorsal vitta fulvous. Prothorax black, 

 with a broad fiilvous vitta on each side. Elytra with their sides 

 straight and parallel to about the end of the anterior third, and 

 thence strongly diverging to enclose the posterior flattened and 

 laterally rounded expansion, which occupies about the hinder 

 two-thirds of the elytra. The upper surface exhibits scarcely any 

 indication of raised lines, and is crossed by two fulvous bands — 

 one at the base, the other somewhat broader and with a strongly 

 indented posterior margin — placed just behind the middle. Between 

 the latter band and the apex the elytra are dark blue, with a some- 

 what metallic tint. Body underneath black, with the middle of 

 the metasteruum and the hind part of the prosternum yellowish 

 testaceous. Last abdominal ventral segment strongly convex, its 

 hind margin angtdarly incised in the middle. 



In this species the lateral expansion of the elytra 

 commences farther back from the base than in the other 

 members of the genus, and this character, together with 

 the almost complete absence of raised lines from the 

 elytra, will serve for its recognition. 



Note. — Dr. Horn has directed my attention to an error 

 in synonymy, which occurs in Bates's last paper {ante, 

 p. 161). Bates places Cyllene rohinice, Forst., and 

 C. jnctiis, Drury, as synonyms of the same species, 

 having evidently overlooked Horn's paper (Trans. Amer. 

 Soc, viii., 1880, p. 136), in which the two forms are 

 shown to be quite distinct. The species which Bates 

 had in view, and which is to be recorded as occurring in 

 Mexico is Cyllene pictiis.
