Head : frons moderately wide, with a small but perceptible 

 gibbosity above the antennae ; the eyes pubescent, narrowly 

 separated below. Proboscis short, with large hairy labella ; palpi 

 comparatively long, 4th joint longer than the 3rd but generally 

 shorter than the 2nd and 3rd together. Antennsa l(J-jointed, 

 short, a little longer than the head ; scape normal ; the flagellum, 

 which is sometimes incrassated at base, has the joints often almost 

 coalescent, tapering and slender towards the tip ; in some species 

 the joints are well separated, without any incrassation at base ; 

 the upperside of the antennae with longer verticillate hairs, the 

 lower side with close short pubescence. Thorax normal, neck 

 moderate, suture distinct. Abdomen rather long, sometimes 

 narrow at base, and more or less club-shaped towards the tip. 

 Male genitalia with the first stout conical joint of the claspers 

 of a coriaceous nature, the second joint bearing a bifid horny 



* The tip of the abdomen is bent over the back, and the geuitalia twisted 

 round, so that it is very difficult to make out the structure.
