ing the apex of the one following it. This variety, 

 too, has the head black, and the mandibles dark sienna- 

 brown. The ventral surface is dingy olive-green. 



The larva spins small silken webs about the tops of 

 its food-plant, Salsola kali ; and when full-fed descends 

 below the surface of the sand and forms a small 

 oval cocoon composed of grains of sand completely 

 woven together with silk. 



The pupa is of very ordinary shape, about two-fifths 

 of an inch long, evenly rounded, broadest at the 

 thorax, and tapering gradually to the anal point. 

 The whole surface is semi-translucent and polished, 

 and all the parts are well defined. The eye-, leg-, and 

 wing-cases are bright green, the thorax and abdominal 

 segments yellow, the abdominal divisions brown, and 

 a distinct green line which shows through the trans- 

 lucent covering extends through the dorsal area. 



The imagos emerged at the end of July and the 

 beginning of August. (George T. Porritt, 3rd April, 

 1884; Entom., May, 1884, XVII, 111—113.)

On the 16th of August, 1874, I received from Mr. 

 John H. "Wood a spruce fir-cone containing a larva, 

 whose ravages were plainly perceptible by the ex- 

 truded particles of light fawn-coloured frass from 

 some of the scales, which still adhered by a thread or 

 two of silk to the cone. It was not till the 26th that 

 I was able to secure this individual to figure and de- 

 scribe, although on two previous occasions I obtained 

 a transient glimpse of it as it left one part of the cone 

 and entered another part ; but on this occasion I 

 caught it on the calico cover of the glass vessel that 

 contained the cone, and then took the following de- 

 scription :
