The cvack across the whig resulted in a small imperfection in the 

 costa of the left foi-e wing, but tlie rest of the wing under the outer 

 portion of the crack was unaffected. The condition of the palpi and first 

 and second pairs of legs pointed to the injury having seriously affected all 

 these parts, and especially to its liiiving caused the loss and displace- 

 ment of tissues, probably, at the date of the injury, of almost fluid 

 consistence. 



The most curious result and evidence of this was that the palpi, or 

 what represented them, and that had apparently developed no scaled 

 surface, had their extremities widely separated and ending behind the 

 femora of the first legs, and were organically fixed to the tissues behind 

 them and to the tops of the first femora. These femora were, in fact, 

 difficult to distinguish, except the inner margin of the left one, and were

solidly soldered to the thorax behind them (I speak as viewing the parts 

 from their ventral aspect, as in the diagram). The second femoi-a were 

 in similar case, and in all four the tibiae were also so far soldered to the 

 representatives of the femoi-a that they were immovable. In the middle 

 line the coxae, or sternal pieces, were represented by irregular and asym- 

 metrical nodules. On the right side the first two femora, or the tibio- 

 femoral articulations, were connected by a loop of tissue, without any 

 scaling. Two processes of similar tissue protruded from the first tibio- 

 femoral articulation on the left side. 



The third pair of legs were apparently normal, being safe beneath 

 the wings, but of the first two pairs of legs only tibiae and tarsi could 

 be recognised. They possess scaling of a fairly normal character. The
