 No. 79-- . 



No. 2470 is the nomotype. 



This species closely resembles H. nigrorufa. Burr, from New 

 Guinea, but differs in the sculpture of the last dorsal segment ; 

 in that species the pairs of minute black tubercles along its 

 posterior margin are wanting, the margin itself is incrassate and 

 depressed in the middle : the pygidium also in that species has a 

 minute spine at each angle : H. feae is smaller, quite differently 

 coloured, and the structure of the last dorsal segment is also 

 different. H. dohertyi, Burr, and H. semihiteus, Burr, are probabh^ 

 only colour varieties of H. feae, or H. nigrorufa. 



All but one of the males are macrolabious ; one (No. 2311, 

 Janakmukh) is c\-clolabious ; the branches are robust, shorter and 

 arcuate, with a pair of sharp teeth.

This is the third known specimen of this curious and rare 

 species. The other two are the type from Bhamo in Burma, and 

 a male from Assam, recorded by me, in the Indian Museum. 



The forceps are contiguous, straight, slender, elongate, and 

 unarmed. Their length is 3*5 mm.
