dark grey cross stripes, so arranged as to divide the surface 

 of the wings into a delicate network of grey lines and white 

 interspaces. Cilia extending round the apex some distance 

 along the costal margin, white, broadly chequered with 

 broad grey spots which throw out delicate rays. The wings 

 hardly possess a fixed pattern of markings, the cross lines are 

 eometimes perpendicular to the costal and dorsal margins, at 

 others rather oblique ; moreover, they do not follow each other 

 at regular distances, nor at the same distances in different 

 specimens, nor indeed in the wings on the two sides of the 

 same specimen, so that hardly any are accurately symmetrical. 

 Underside similar to the upper, but a little whiter ; legs 

 whitish grey. 



Female without legs or antennas — a mere maggot — but 

 having in the curious brown mask, which does duty for a 

 head, two blackish hollows in the place of the eyes, a black 

 spot where the mouth should be, and slight curved ridges at 

 the side, which seem to suggest antenna-cases. Body red- 

 brown, excessively wrinkled (in the dry specimen), segments 

 deeply divided, anal segment abruptly cut off, but having in 

 the middle a protruding ovipositor in three abrupt telescopic 

 divisions, the final one being a mere point. For the sight of 

 this dried and shrivelled specimen, which is only one- 

 twentieth of an inch in length, I am indebted to Mr. B. A. 

 Bower. It was reared from one of two cases, the sole result 

 of long search by himself and Mr. Geo. Bird. A similar and 

 most exhaustive search last spring, for the purposes of this 

 book, by Mr. F. G. Whittle, was wholly without result so far as 

 this species was concerned. I think, however, that when 

 fresh the female would be about one-third of an inch long, 

 with rather ridged segments, abruptly cut off anal segment, 

 and protruded ovipositor. The present specimen seems to 

 have forced itself out of its case after laying its eggs. 



(It has been necessary to exercise especial care in obtaining 

 authentic females of this and the last species for description, 

 from the circumstance that in some of our best collections
