116 CHOEROOAMPA PORCELLTJS. 



Chcerocampa POROELLUS. 

 Plate XXVI, fig. 1. 



Mr. Buckler figured a larva July 29th, 1861, food 

 Galium verum and mollugo ; a green larva on Galium 

 verum and palustre August 2nd, 1866; and one on 

 Galium verum August 26th, 1869. I bred the moth, 

 June 16th, 1867, and on July 1st — 7th, 1886, from 

 pupae sent to me by Mr. W. H. Harwood. On July 

 20th, 1886, I received from Mr. Gr. T. Porritt some 

 young larvse, which had been hatched on the journey 

 from him. These moulted four times, July 25th and 

 31st, and August 6th and 11th, and seemed to thrive 

 well until they were all but full grown, and then they 

 all sickened and died. 



However, on August 6th, a full-grown larva was 

 found by my daughter in Arundel Park, Sussex, feed- 

 ing on Galium verum, and this soon spun up and 

 became a pupa. The newly-hatched larvse seemed to 

 like the flowers of Galium verum, but very soon altered 

 their taste and showed a preference for the leaves, appa- 

 rently not caring to touch the flowers when a fresh 

 supply of food was given to them. 



The egg is very broad oval in form, 1*2 mm. long 

 and 1 m. wide, the shell thin and shining, in colour I 

 suppose light green. The young larva is a little over 

 3 mm. long ; on segment 12 (no horn) but a raised 

 wart set with two clubbed bristles (as if the horn had 

 been absorbed, leaving no more than its tip), the places 

 of the usual tubercular dots marked by tiny short 

 knobbed black bristles ; the head and segment 13 set 

 with short black hairs ; the colour pale grey-green on 

 the back, on the front of each segment a band of 

 deeper tint than that on the hinder part, the side 

 greyer, the spiracular region almost whitish, the head 

 and belly pale yellower green ; in a day or two a
