ADEPHAGA. 



much less rapidly narrowed behind. 

 Inner claw on front tarsi of male 

 about two-thirds as long as the 

 outer, wider and more strongly- 

 curved ...... 



bf . Elytral interstices in the female 

 punctate across the apex and 

 sometimes along the distal half of 

 the suture. Similar to H. ruji- 

 collis, but scarcely so wide at the 

 shoulders and more gradually nar- 

 rowed behind. Dark red-yellow in 

 colour with the black markings on 

 the elytra more pronounced . 

 b*. Elytral interstices in the female 

 without punctuation, generally 

 smaller than H. ruJicoHis, compara- 

 tively wider at the shoulders and 

 more rapidly narrowed behind. Claws 

 on front tarsi of male subsimilar . 

 b. Thorax not more than twice as 

 broad as long, the sides moderately 

 convergent in front. Elytra widest 

 in the middle, with an oblique pale 

 band from the shoulder to the suture, 

 followed by another oblique band of 

 approximately equal width, but com- 

 posed of short, black, longitudinal 

 lines ...... 



B. Elytra with the dark lines 1-4 of 

 uniform width throughout, 5-7 less 

 decidedly, or not at all, interrupted. 



a. Sides of elytra usually sub-parallel, 

 as in II. lineatocollis. Elytral inter- 

 stices of the female punctate through- 

 out. Left side-lobe of fedeagus sub- 

 falcate, without a fringe on its 

 concave edge ..... 



b. Sides of elytra continuously curved. 

 a*. Elytral interstices of female punc- 

 tate on the apical half, the punctua- 

 tion becoming gradually evanescent 

 about the middle. Left side-lobe of 

 the sedeagus with a fi'inge of long, 

 more or less coherent, hair-like 

 strips of delicate membrane on the 

 distal half of its concave edge.
