128 TROCHILITJM TIPULIFORME. 



Trochilium TIPULIFORME. 



Plate XXVIII, fig. 3 (see ante, p. 49). 



Mr. Buckler's notes are, " March 9th, 1861, in pith 

 of currant ; in stems of black and red currant, March 

 22nd, 1869." I have several times captured the moths, 

 apparently just emerged, in the second and third weeks 

 of June. (J. H., 25, 11, 86.) 



Troohilium myop^forme. 

 Plate XXIX, fig. 1. 



Mr. Buckler figured this species March 5th, 1867, 

 from larvso in bark of apple trees. In 1886 Mr. G. T. 

 Porritt gave me some larvae sent to him from Wicken, 

 on May 21st, and again on June 26th, but most of 

 them had been injured in being extracted from the 

 apple-bark ; however, one of the first batch had 

 become a pupa by June 26th, and one of the second 

 batch also came to full growth, and from it I bred the 

 moth on August 10th. 



The larva I described was 15 mm. long, of even bulk, 

 rather flattened, the head with rounded sides, retractile ; 

 segment 2 wider than the others, the skin thin, 

 wrinkled ; the segments distinctly cut, the hinder side 

 of each being higher than the front of the next ; the 

 usual dots inconspicuous, but slightly raised and placed 

 on horny spots, each with a short bristle ; the whole 

 of the back of segment 2 is covered with a horny plate, 

 the hinder curve of which spreads partly over 3 ; the 

 colour dirty white, with a pinkish pulsating dorsal 

 vessel, and an internal purplish pink tinge from 5 to 8 ; 

 the head shining red-brown, the plate on 2 slightly 

 tinged with bright brown ; the ventral prolegs very 

 little developed.
