Long, slender, cylindrical, smooth, and with the surface 

 destitute of tubercles and spines. The head oval, simple. 

 The antennse short, not reaching beyond half the length 

 of the fore femora ; the basal joint very broad, oval and 

 flattened. The segments of the thorax and abdomen are 

 simple ; the eighth segment of the latter the shortest ; the 

 ninth with its hinder angles prominent, and its hind mar- 

 gin slightly notched in the middle. The operculum is 

 long, but does not extend beyond the extremity of the 

 terminal segment of the abdomen ; it is convex towards its 

 apex. The legs are long and slender ; the femora of the 

 fore legs denticulated along the whole of the upper edge ; 

 the tibiae long and slender ; the middle legs shorter and 

 rather thicker than the rest, the femora with three (some- 

 times two, rarely one) small foliaceous lobes near the base 

 on the upper edge, and a more or less distinct spine on the 

 under edge near the tip ; the hind femora have a spine near 

 the base on the upper edge, and another smaller on the 

 under edge near the tip.

I am not satisfied as to the specific distinction between 

 this and Ph. Cuniculus, depending as it does on the exist- 

 ence of horns on the head, and want of spines at the base 

 of the middle legs in the latter, and vice versd in the 

 former. 



The Entomological Society of London has received an 

 Indian specimen of this species from Mrs. Hamilton, which 

 appears still further to connect the present species with the 

 preceding ; having two diverging spines between the eyes ; 

 the mesothorax granulated ; the middle femur on the right 

 side with three foliaceous spines towards the base on the 

 upper side, whilst there is only one on the left femur; 

 the middle tibia on the right side is also three-spined on 

 the upper edge, whilst the left one is only 1-spined ; the 

 hind femur has also one spine on the upper edge near the 

 base. The proportions are as follow : —

Entirely smooth, and of an olivaceous-brown colour, with 

 a slender pale luteous line down each side of the body ; 

 long, narrow, cylindrical. Head longer than wide, gradually 

 narrowed from the eyes to the base, which is slightly ele- 

 vated and divided into four parts or small tubercles. The 

 antennse are scarcely one and a half time longer than the 

 head ; the basal joint is oval and flattened ; the remainder, 

 twenty-three or twenty-four in number, are short and fili- 

 form. The mesothorax is slightly dilated above the base of 

 the middle feet. The mctathorax is long, its hinder division 

 rather short. The six basal segments of the abdomen are 

 cylindrical and simple ; the three terminal segments are 

 broken off in the unique specimen before me, so that I am 

 unable to determine the sex. The fore legs are also want- 

 ing ; the middle legs are comparatively short ; the femora 

 have two small lobes on the under side near the base on the 

 opposite angles of the limb, and near the tip they have a 

 minute spine on the under edge ; the tibiae are slender, 

 with a few very minute and slender spines ; the basal joint 

 of the tarsi is about as long as the second and third joints 

 together. The hind legs are rather longer and simple, ex- 

 cept that the femora are armed with a minute spine on the 

 under side near the tip. 



This species seems to approach nearly to B. Hyphereon 

 in its general characters.
