a marked, slightly inwardly directed, cone-like process on each side, imbricated 

 and with two minute hairs. Two stiff hairs also project from the vertex. Eyes 

 large, red to dark red. Proboscis pale, apex slightly darkened ; reaching to or just 

 beyond the third coxae, narrow ; apical segment a little narrower and longer than 

 penultimate. Legs of same colour as body, except the tarsi which are darkened ; 

 very short stiff hairs on the tibiae. Cornicles of same colour as body, moderately 

 long, but shorter than the fourth antennal segment, slightly swollen from the middle 

 onwards ; faintly imbricated, sometimes slightly expanded at the base. Cauda pale, 

 short, bluntly triangulate, spinose, with two short hairs on each side ; projecting 

 well beyond the cornicles. Anal plate slightly darkened, narrow, spinose, with
