There are five males and three females of this species in 

 the Museum, including a ? from Abyssinia received in 1855. 

 A hairy, elongate insect, black or piceous, with the pro- 

 thorax and tarsal claws, and usually the scutellum also, 

 testaceous, the elytra with a faint bluish tinge ; the antennal 

 joints 3-10 elongated and slightly widened, 11 curved, 

 hollowed on its inner face, much longer than 10 in ^ . 

 The faintly indicated elytral costse are exaggerated in 

 Reiche's figure. I. fulvicoUis has the antennae less widened 

 than in 1. dlmidiata, both species occurring at the same 

 locality in Abyssinia. /. henonii, Fairm., from Choa (1883), 

 may be a form of the ? with an infuscate prothorax ? The 

 genital armature is very like that of /. dimidiata and 

 /. plectrophora.

 more of their length) nigro-cyaneous. Head long, narrow,
