CEDIONYCHIS. 415 



second and third joints of the antennae as nearly equal ; the latter is, however, at least 

 one half longer than the second joint, as is the case with nearly all the species of the 

 genus before me. From (E. virgata the present species differs in the entirely black 

 head, with the exception of the frontal elevations, which are testaceous ; in the nearly 

 black underside and entirely black legs, and in the position and shape of the marginal 

 black vitta of the elytra — the marginal vitta in (E. chevrolati being placed close to 

 the lateral margin, leaving the anterior portion of it, as well as the elytral epipleurse, 

 testaceous, and after extending round the apex uniting with the sutural band ; whilst 

 in (E. virgata the lateral black band is placed further from the lateral margin and does 

 not join the sutural vitta. After comparing Mr. Baly's type with that of (E. qiiinque- 

 vittata, Jac, I find that, although the latter differs in the much narrower elytral 

 stripes, which resemble those of (E. virgata, yet it agrees so closely in all other respects 

 that it would not be wise to look upon it as anything else but a variety ; the colour 

 of the underside and legs, as well as that of the head, also agree with Baly's species. 

 In the species from Guatemala the legs and underside are dark fulvous, while the 

 other characters agree with the type.

 Hob. Guatemala, Capetillo 1 (Champion). 



This species approaches (E. chevrolati in the position of the elytral bands, the outer 

 and sutural ones being joined at the apex; these bands, however, are very narrow and 

 regular, and leave no trace of a yellow elytral margin ; the latter, as well as the 

 epipleurse, are entirely of a bluish colour. (E. ornata is of a very convex shape, but 

 varies in size ; all the specimens have a small piceous spot on the vertex (the latter 

 being generally of a more reddish-fulvous colour), and the thorax seven or five more or 

 less distinct piceous small spots ; the antennae have the third and fourth joints of 

 nearly equal length ; the shape of (E. ornata is quite different from that of (E. quadri- 

 lineata, being very convex instead of flattened.

Hah. Panama (Boucard). — Colombia x 2 . 



A specimen from Panama before me does not differ from the Colombian insects in 

 my collection ; the size is small and the discoidal band of the elytra double the width 

 of the sutural one. Von Harold has given a renewed description of this species, to 

 which I must. here refer.
