Described from a similarly coloured ))air, the (^ without 

 dcHiiitc locality. The exam pics with partly infuscate legs 

 and antcuuje, the <$ with thickened posterior femora, seem to 

 belong to the same specie^, the genital armature being similar 

 in the two forms. 1. femorata is closely related to /. (jurhami., 

 Pic, as here restrictetl, differing from it in the strongly 

 incrassatc posterior femora in ^ , the simple terminal dorsal 

 segment in both sexes, and the slightly dilated antcnnic. 

 The median and lateral lobes are much shorter than in 

 the two males of /. yorhami dissected. The type, cJ , of the 

 present species was presented to the British Museum many 

 years ago.

'l"he dissection of two males from the Nilgiri Hills shows 

 that /. yorhanii is a Ibrm of /. dimeUena, Walk., with infus- 

 cate, submctallic elytra, the variety diversipennis being 

 intermediate. The two insects are common in the Nilgiri 

 Hills, but as /. gorhami does not appear to extend to Ceylon 

 it is here given specific rank. The anterior portion of the 

 head, the antennae, scutelhnn, legs, and under surface are 

 testaceous, as in I. dimeUfna, and the terminal dorsal abdo- 

 minal segment is similarly cleft at the tip in the two sexes, 

 the apex appearing bilobed.
