 small central ridge. Pronotum with a granular surface, truncate 

 in front, acute angled behind, compressed centrally on the sides, 

 and above on each side of median carina ; this last with one notch ; 

 lateral carinae jjrominent only in the middle. Wing covers extend- 

 ing considerably beyoud the end of the abdomen. 



The species may be separated as follows : — 



( Base of the wings, pale j'ellowish rugosiis. 



I Base of the wings, I'ed tuberculattis. 



Hippiscus rugosus. Scudder. 



Head and thorax, dark brown ; two yellowish bands run from 

 behind the eye backwards and inwards, nearly or quite meeting 

 one another a little in advance of the middle of the pronotum, 

 where they diverge and strike the hinder edge of the pronotum at 

 the outer angles ; there are two yellowish spots, one below the 

 other, on the sides of the pronotum ; wing covers marked with 

 large dark blotches, generally occupying the larger portion of the 

 wing ; the tip of the wing cover pellucid, nearly free from spots ; 

 wings with the basal color, pale yellowish, and the apical portion 

 dusky. Length of body, from one inch to one and one-fourth. 



Hippiscus tuberculatus. Palisot de Beau vols.

Antennae of female rather short and stout ; pronotum granu- 

 lated, scarcely spotted, plain above ; median carina of uniform 

 height throughout. Wing covers spotted with brown ; base of 

 wings red, costa and outer margin fuscous. 



■ This species has been generally cvWed phoenicopterus ; but Saus- 

 sure has shown that they are distinct species.

Head prominent, vertex elevated and tumid ; antennae of the 

 male not thickened before, nor tapering at, the tip ; posterior lobe
