and a single long and fine hair, these almost or quite hide the green 

 ground of the upper surface of skin, the spiracles are black, the smooth 

 naked belly is of a green, rather less dark than that of the back, the 

 anterior legs are black and shining with light green joints on the outer 

 side and light green inner surface, the ventral and anal legs are of a 

 lighter green than that of the belly and semi-transparent. 



The cocoon is about 7 or 8 lines in length, and from 3i to 4 lines 

 in width, somewhat fusiform, rising convexly in the middle, bluntly 

 rounded off and rather flattened at each end to the surface on which 

 it is spun (generally some rock or stone) ; it is usually very smooth, 

 though sometimes a few slight longitudinal wrinkles are towards the 

 front or roundest end ; it is of a light pearly-greyish tint having more 

 or less of a silvery lustre, and after the moth has escaped is 

 semi-transparent. 



The pupa, is from 5^ to 6| lines long, and sometimes works its 

 way quite out of the cocoon before the moth is disclosed ; it is of the 

 usual Zygcena form, with long antenna- and leg-cases free nearly their 

 whole length, the shortish wing-covers with nervures in strong relief 

 have their margins prominent from the body, the abdomen tapers just 

 towards the rounded-off tip, and across the back of each ring anteriorly 

 is a narrow ridge thickly set with most minute hooks pointed backward ; 

 the colour is blackish-green on the abdomen and all the other parts 

 black, and with rather a dull surface.

DESCRIPTION OF THE LARVA OF CR AMBUS INQUINATELLUS. 

 BT G. T. PORRITT, F.L.S. 



At the end of April last, Mr. W. H. B. Fletcher sent me about 

 two dozen larva? of a Cramhus he had found about grass-roots, at 

 Worthing, but the species he did not know. I placed them in a pot 

 of growing grass, where they formed slight silken galleries near the 

 roots on the surface of the soil, in which they lived during the day, 

 and apparently coming out and feeding on the grass stems only at 

 night. During May, I lost sight of them, and judged they had all 

 gone below the soil to pupate. Through June and July, I anxiously 

 awaited the emei'gence of the images, but none appearing, I quite 

 gave them up as all dead, and was, therefore, very agreeably surprised 

 at quite the end of August and early in September, to breed from them 

 a nice and varied series of C. inquinatellus. 



Length, about three-quarters of an iiicli, and fairly stout in proj)ortion ; head 

 uarrower than the second segment, the lobes full and rounded, and botli it and the
