which, however, does not reach far outwards. IMeta- 

 sternum quite short. Hind body small and slender, but 

 dissimilar in the two sexes ; in the male placed on a very 

 different level to the metasternum, but a good deal 

 arched; in the female larger, and at the base much less 

 discontinuous with the metasternum — in this sex with 

 exsei'ted elongate membranous apical segments. Elytra" 

 of peculiar form, with truncate base and well-marked 

 shoulders, Avith their sides much deflexed, nai-rowed to- 

 Avards the apex so that they are there acuminate: they are 

 produced beyond the extremity of the hind body, and at 

 their termination have a divergence or opening between 

 them, beyond which the wings project as a slender con- 

 tinuation, simxilating a short ovipositor of some orthop- 

 terous insect. Anterior legs short; middle and hind ones 

 elongate, the latter remarkably so, the thighs slender at 

 their extreme base, but with an elongate ajncal thick 

 part, wdiich is more developed in the male than in the 

 female; tibife laterally compressed, so as to be very 

 slender viewed from behind, and yet appearing rather 

 stout when looked at laterally, thinner at the knee than 

 at the apex, a little sinuate when their inner face is 

 looked at. Hind tarsi with elongate and slender basal 

 joint, it being tAvice or three times as long as the tAvo 

 folloAving together; 3rd joint very deeply bilobed, the 

 lobes quite slender ; the clothing of the under side of the 

 basal joint the same as the upper side, but that of the two 

 folloAving joints remaining as usual in the family.
