HYMENOPTERA. 445 



This animal lives much under ground, and, like the beetle, lays its 

 eggs in some moist place under ground to hatch. Its legs are very 

 strong, more especially its fore-legs, for digging. Its head is in some 

 degree covered by the back scale of the fore-legs, like the armadillo, 

 which probably fits it better for burrowing. 



The oesophagus begins just between the roots of the two pincers, 

 behind the anterior flap that covers the parts about the mouth, and 

 above the root of the tongue ; which is composed of different parts. It 

 passes through the head in a kind of horny case; then through the 

 neck and chest to the abdomen. It then opens laterally into a bag or 

 crop, but it appears to go to an oblong or pyramidal body or cavity, 

 which I suppose to be a gizzard. The internal structure of this is very 

 curious ; full of cells placed in rows parallel to the axis of the body or 

 cavity ; but whether they are covered with a thick cuticle or not, I do 

 not know. 



This is similar to the gizzard of the large green, small-eyed grass- 

 hopper 1 . 



From the apex of this passes a duct which dilates into a bag, which 

 I suppose to be the stomach. This stomach, as it were, encloses the 

 gizzard on the fore and back part, like two cseca, as in the grasshopper. 

 From this bag passes out the intestine somewhat straight ; but, at its 

 lower part, it becomes convoluted or twisted upon itself, where it 

 receives the ducts of the liver ; it then forms the rectum and goes to the 

 anus. On each side of the rectum is a white bag, which I believe opens 

 at the anus. The ducts of the liver appear to begin from a round bag, 

 which lies in among them 2 . 



In a small one, which I suspected to be a male, I found the air-ducts 

 of a dark colour, very regular, one on each side of the abdomen, com- 

 municating across ; a good deal like the silk-worm when it is casting 

 its coat. Was this a young one ? and do they grow after they are per- 

 fect ? I rather suspect it was a young one, because it had no wings, 

 only small flaps, which were hollow, somewhat like those in the chry- 

 salis-beetle. 



From the intestine, this animal should be classed with the grass- 

 hopper 3 .
