HlPPARCHIA HyPERANTHUS. 



Plate V, fig. 3. 



In 1861, July 27th, I received eggs from Dr. Knaggs, 

 the larvae from which hatched August 18th, and I must 

 have carried them through the winter, and sent some 

 to Mr. Buckler in the spring of 1862, but I made no 

 further notes. On July 28th, 1885, I captured a 

 butterfly, and confined her with plenty of growing 

 grass, Dactylis glomerata, Poa annua and others ; next 

 day, July 29th, she laid a great many eggs, but without 

 attaching them to anything ; they were simply dropped 

 and I found them on the bottom of the cage. The 

 larvae hatched August 19th, and moulted about the 

 end of September ; they are now about 5 \ mm. long, 

 sluggish, but feeding a little on Triticum repens. This 

 species hibernates in the larva stage, and feeds up in 

 May. 



The egg is dumpy, conical in shape, with rounded 

 top, about "7 mm. high, more than *8 mm. at its 

 widest, and about *6 mm. over the top; the shell 

 shining, faintly reticulated (or pitted) in rows ; this 

 ornamentation is so slight that it cannot be compared 

 to ribs. The colour at first yellowish- white ; this soon 

 turns to pale brownish, but the shell remains clear and 

 shining, and in about three weeks time the head of the 

 larva shows brown with two small black dots of eyes. 

 The young larva has a large head, and a stumpy body 

 tapering to the tail, about 1*7 mm. long, the usual dots 

 large, and each bearing a stiff, curved, ragged bristle ; 

 there are no anal points till after a moult ; colour pale 

 drab, the head horny, warm brownish, the dorsal and 

 subdorsal lines yellowish-brown, the dots slightly 

 darker than the ground. When between 5 and 6 mm.
