two spines, the prothorax with several pairs of smaller 

 spines, and the mesothorax with numerous spines placed 

 irregularly ; the sides of the metathorax in the female are 

 also spined, as well as the under side of all the femora in 

 the male and female. The male has the three terminal seg- 

 ments of the body thicker than the preceding ; the female 

 has the sixth abdominal segment rounded, and rather di- 

 lated at the sides ; and the operculum of the same sex ex- 

 tends nearly an inch beyond the extremity of the abdomen.

The male of this species is quite slender and subcylin- 

 dric, with a glossy surface, and in its dried state of a 

 light brightish brown colour, with the sides of the head 

 and of the terminal segments of the abdomen white. The 

 head is oblong, very convex, with two strong short horns 

 in the middle of the crown, that on the right side being 



the larger ; they are tipped with a short acute black point ; 

 there are also two small black granules on the hind part of 

 the crown of the head. The antennas are long and slender ; 

 the joints are about twice as long as thick, there being 

 sixty-four joints in each antenna. The prothorax is fur- 

 nished near its fore margin with two black points ; and the 

 mesothorax has four pairs of similar points, the hinder part 

 being quite smooth. The tegmina are about two-thirds of 

 the length of the mesothorax, oval, with a strongly elevated 

 protuberance in the middle ; they are of a dirty glaucous- 

 grey, with the edges varied with white markings. The 

 wings are about half the length of the entire body, milk- 

 white, with a slight rosy-brownish tinge ; the anterior part 

 dull glaucous-grey, darker at the base, with white markings, 

 especially on the fore margin. The abdomen is very long 

 and slender ; the sixth segment with a small lobe on each 

 side ; the three terminal segments rather wider than the 

 rest, and short ; the terminal ventral segment not extending 

 beyond the eighth dorsal segment, and considerably dilated 

 at its base ; the two terminal styles porrected and obtuse. 

 Legs short and strong ; the anterior pair simple ; the four 

 posterior femora slightly spined along the under edge ; 

 basal joint of the tarsi about as long as the three following 

 joints. Meso- and metasterna with a few black points. 



The female is of an opake dirty glaucous-white colour. 

 The horns of the head of unequal size, as in the male. The 

 pro- and mesothorax much more thickly marked with 

 small points, black at the tip. The tegmina are short and 

 nearly rounded, thickly reticulated with paler nervures, and 

 with a moderately raised tubercle beyond the middle. The 

 wings are nearly equal in length to the tegmina ; their an- 

 terior portion is dirty greenish-brown ; the hind part 

 thickly reticulated with black veins. The abdomen is very 

 long and gradually attenuated to the tip ; the oviduct is 

 very long and boat-shaped, the exserted portion being 

 nearly equal to the four preceding segments in length.
