of which the larva exclusively feeds, concealing itself gene- 

 rally on the under side of the leaf. Head prone, subglobose, 

 shghtly notched on the crown, of the same width as the 2nd 

 segment : body obese, velvety, rather attenuated towards 

 both extremities, having the incisions of the segments 

 strongly marked and the dorsal area transversely wrinkled ; 

 the anal claspers are slightly divergent, and the entire surface 

 of the body has here and there a feeble bristle or hair. 

 Colour of the head and body dingy sienna-brown, with a 

 very narrow medio-dorsal black stripe, in close proximity 

 with which is a black dot on each side of each segment, and 

 a second black dot behind this and rather more distant ; the 

 spiracles are also black, and the entire dorsal and lateral 

 ■areas are delicately reticulated with black ; the legs, claspers, 

 and ventral area are somewhat paler than the dorsal area, and 

 entirely without markings : this larva is full-fed in October, 

 and, spinning a slight web, hybernates while yet unchanged ; 

 the pupa state is assumed in the spring, and the moth 

 appears on the wing in June. I am indebted to Mr. Machin 

 for a pair of the full-fed larvae of this species, and the 

 information respecting its habits. — Edivard Newman. 



Description of the Larva of Pionea margaritalis. — The 

 eggs are laid amongst the flowers of Sinapis alba (white 

 mustard), and, according to my kind correspondent, Mr. 

 Brown, of Cambridge, also on Sinapis arvensis (charlock), in 

 July: the young larvae emerge from the 1st to the 11th of 

 August, and, as soon as hatched, commence spinning a web 

 or tent, under which they conceal themselves by day, three 

 or four under one tent ; but come abroad by night, and feed 

 on the seed-pods, first gnawing a hole in the pod just above 

 the seed : they are full-fed at the end of August, but still 

 remain in their tents by day ; when disturbed they fall out 

 and hang by a thread, but never roll in a ring. Head nar- 

 rower than the 2nd segment, into which it can be partially 

 received, slightly notched on the crown, and very glabrous: 

 body attenuated towards the anal extremity, each segment 

 dorsally divided into two sections by a transverse fold : body 

 slightlj' warty, each wart emitting a bristle. Colour of the 

 head black and very glabrous, the labrum and antennal 

 papillae white ; a narrow ring round the neck and tlie medio- 

 dorsal surface of the 2nd segment pure white : colotir of the
