HYLODROMUS.— CLEOPHES. 475 



HYLODJROMUS. 



Hylodromus, Clark, Cat. of Halticidse, p. 143 (1860). 



Hylodromus was established on a species (H. dilaticomis, from the Amazons 

 having the third to the sixth joint of the antennae dilated and compressed, and a 

 double spur to the hinder tibiae: both these characters are present in an insect 

 obtained in the State of Panama, a species which agrees also in most other structural 

 characters described by the author ; in its general appearance and shape, however, our 

 insect agrees with Omammatus, and the elytra are entirely glabrous and without 

 pubescence. 



1. Hylodromus basalis. 



Fulvous ; the seven lower joints of the antennae, the head, and thorax, piceous ; the terminal joints of the 

 antennas, the anterior legs, and the posterior tibiae, flavous ; elytra with a deep basal depression, their 

 basal half piceous, the rest fulvous. 



Length 2 lines. 



Head impunctate, glabrous ; the frontal tubercles very strongly developed ; the basal part of the clypeus very 

 convex and greatly deflexed ; the labrum testaceous ; the maxillary palpi strongly incrassate ; antennae 

 half the length of the body, the second joint short and rounded, the three following joints very robust and 

 thickened, the sixth joint also stout but more elongate, the four apical joints short, flavous ; thorax about 

 twice as broad as long, the sides concave at the middle, the angles acute and thickened, the anterior ones 

 furnished with a single seta, the surface rather depressed across the basal portion, very remotely but rather 

 distinctlv punctured, of a piceous or very dark fulvous colour, the angles and the extreme basal margin of 

 a more flavous tint ; scutellum rather broad, impunctate ; elytra but slightly convex, deeply transversely 

 depressed below the base, the latter raised and strongly punctate-striate, the punctuation finer towards the 

 apices, rather more than the posterior half of the elytra fulvous, the basal portion piceous, very shining 

 and glabrous ; posterior femora dilated at the middle into a triangular tooth, piceous, their apices, together 

 with the other legs, flavous ; posterior tibiae strongly curved at the base, and armed with a very long 

 double spur. 



Hah. Panama, Bugaba (Champion). 



The triangularly dilated posterior femora, in connection with the shape of the antennae,, 

 will help in the recognition of this species. 



CLEOPHES. 



Body oblong-ovate, glabrous ; maxillary palpi filiform ; antennae filiform, the terminal joints slightly thickened, 

 the third joint twice the length of the second ; thorax transverse ; posterior tibiae serrate, armed with a 

 single spur. 

 I am unable to find a place amongst the genera of Clark's monograph for the insect 

 described here, on account of the very distinct serration of the posterior tibiae in con- 

 nection with their single spur. Ptinomorpha, Harold, possesses these characters, but 

 differs in the incrassate maxillary palpi, the different structure of the antennae, and the 

 subquadrate thorax.
