inwards like an isosceles triangle, with the apex pointing back- 

 wards, and reaching back to the fore legs, and nearly to the pos- 

 terior termination of that segment. Abdomen flattish, with ten 

 segments, all arranged telescopically, each fitting into that before 

 it, slightly convex above, concave below, perliaps from shrinkage ; 

 marginal separation between the upper- and underside distinct ; 

 anal segment small and open at the apex. A depressed line runs 

 down the middle of the back of the whole larva ; and there are 

 hairs along the sides. Stigmata apparently angular in shape, and 

 eight pairs in number : there are none on the last two segments ; 

 and the appearance of those in the first two segments is not so 

 distinct as in the six that follow. Legs not very short, termi- 

 nating in a single pointed article. 



The colour is pale fawn, except the head, which is brownish. 



For convenience of reference and provisionally, until the 

 perfect form of this insect be known, I have named it Astraptor 

 illuminator, from aarpuir.), a flash of lightning.
