Rostrum about the length of the head, sometimes distinctly- 

 hairy ; nasus wanting ; palpi with the first three joints of about 

 equal length, the second thickened towards the apex ; terminal 

 joint equal in length to the two preceding joints in H. cinerascens 

 and H. ornatipes, the length of the three preceding joints in H. 

 reinota. Antennae long, more or less distinctly covered with dense 

 erect hairs ; first joint of the scapus obconical, twice the length 

 of the second, the latter cyathiform ; flagellar joints progressively 

 decreasing in length and thickness; ^ antennte 11-jointed, more 

 or less the length of the entire body ; 2 13-jointed, more or less 

 the length of the thorax (PI. vi., fig. 34, H. cinerascens^. Front 

 broad ; rather convex. Collare short. ^ forceps narrower than the 

 preceding segment, of simple structure (PI. vi., fig. 33, H. cineras- 

 cens); 5 ovipositor with straight valves ; the latter long in S. orna- 

 tipes, the upper and lower being about equal in length, short in H. 

 cinerascens, the lower a little shorter than the upper. Legs long and 

 slender; in H. remota very long and very slender; tibiae with minute
