SPHEOIA APIFORMIS. 125 



the pupa ; the tongue-case straight with the tip free ; 

 the wing-cases small but distinct, and at their lower 

 ends free for 3 mm. ; each of the first five segments of 

 the abdomen has two transverse rows of sharp points, 

 one at the beginning of the segment, reaching across 

 the back and below the spiracles, the other about the 

 middle of the segment and not so long ; the next three 

 segments have one row each, but of stouter points. 

 The tail is rounded off underneath, with no spike but 

 a rough scutcheon. The back of the thorax is rounded, 

 and falls in a little at the waist. The back of the 

 abdomen goes on in a long slight curve, the outline of 

 the belly straighter; the skin glossy, the colonr rich 

 brown. Before the emergence of the moth the pupa 

 works its way out of the cocoon. (J. H., 24, 11, 86.)

Mr. Buckler has two dates for this species ; " taken 

 from the pith of a sallow stem of 1J inches diameter, 

 May 1st, 1861, and from poplar June 5th, 1861." I 

 give his words in full, because of the two kinds of wood 

 being mentioned; I know nothing of this species at 

 large from my own observation, but have understood 

 that its food is the wood of sallow stems. 



In 1886, March 27th, Mr. F. Norgate, of Downham, 

 Suffolk, sent me some larvse ; others were sent on 

 March 31st by Mr. A. Houghton, of Wicken, and on 

 May 21st by Mr. G. T. Porritt ; some of these larvae 

 had been extracted from their galleries, but most of 

 them were sent in their galleries bored lengthwise 

 through sallow stems, which varied in diameter from 

 half an inch to two inches or more. Mr. Norgate in- 

 forms me that he finds the larvaa all through the 

 winter, and up to the first week of July, in their 

 galleries in the wood of Salix caprcea from about the
