above; the subspiracular stripe light sulphur-yellow ; 

 the belly arid veutral legs rather paler green than the 

 back ; the tubercular dots whitish-buff, with minute 

 blackish centre ; the spiracles dark brownish-red, finely 

 outlined with black ; the hairs of all the dots exceed- 

 ingly fine and soft. These larvae disliked being exposed, 

 and were only quiet when they could get on the under 

 side of a leaf. The anterior legs black on their outer 

 surfaces, or else entirely, and shining. The surface 

 of the second segment shining. One larva died, and 

 one spun up between two elm leaves in a thin silken 

 cocoon scarcely to be so called. The pupa rather over 

 half an inch long, thick and stumpy in figure, rather 

 rounded in character anteriorly, and tapering suddenly 

 to the anal tip, which ends in two curly-topped spines, 

 which are fixed or held fast in a rather dense patch of 

 silk spun on the leaf in the cavity or rounded-over 

 chamber formed by spinning the leaves together ; the 

 chamber is not otherwise lined; the surface of the 

 pupa appears of a violet tint and dull from being 

 covered with a bloom or dust. The moth emerged on 

 the 1st of August. (W. B., 1875, Note Book II, 194, 

 199.) 



COSMIA ARFINIS. 



Plate LXXXVI, fig. 5. 



On the 5th June, 1886, I received three larvae of 

 this species from the Rev. G. H. Raynor, of Cambridge. 

 They were feeding on elm, and two days later I de- 

 scribed them as follows : 



Length rather over an inch, and of average propor- 

 tionate bulk ; head glossy, the lobes rounded, about the 

 same width as the second, but narrower than the third 

 and following segments ; body cylindrical, but has an 

 uneven appearance, owing to the clearly-cut segmental 

 divisions ; it tapers from the fifth segment to the head, 

 and the thirteenth segment shelves off abruptly from
