ANTHROCERA TRIFOLII. 97 



I measured were about 2 mm. shorter than those of 

 filipenduke, but I could see no other difference. (J. H., 

 20, 10, 86.) 



AnTHROCEEA FILIPENDUL^l. 



Plate XIX, fig. 4. 



This species was figured by Mr. Buckler many times ; 

 Fig. 4 was taken some time in the spring of 1865, but 

 I have not the exact date ; the full-grown larva was 

 figured in several years at dates varying from May 

 13th to June 29th, and the imago also was bred by him 

 on various days from June 1 1th to August 1st ; sain- 

 foin, Trifolium, clover, and bird's foot trefoil are the 

 food-plants recorded by him. I have myself in former 

 years taken the larva much oftener than I noted its 

 capture. Dr. Knaggs sent me larvee on July 5th, 1861 ; 

 in 1869 I found pupge from which I bred the perfect 

 insects August 14th — 24th. In 1886 I received larvae 

 from Mr. G. C . Bignell on June 8th ; from Mr. F. N. Pierce, 

 of Liverpool, June 17th ; from Mr. G. T. Porritt, June 

 18th. The first spun up on June 14th ; I bred the per- 

 fect insects July 10th, 14th, 16th, and a few days later ; 

 on July 11th Mr. G. C. Bignell sent me eggs ; in 1869 

 I had larvae hatching on September 7th, but this was 

 late for them. Thus we have the imago in flight in 

 May, June, July, and August; the larvae hatched in 

 less than three weeks from the egg-laying, then hiber- 

 nating when quite small, and feeding up in early 

 summer, the pupa stage lasting about three weeks. 



I have examined the egg under the microscope, but 

 can only say that it is much like that of trifolii, perhaps 

 a trifle shorter and stouter ; my memory, assisted by 

 figures given me by Mr. Buckler, recalls the young 

 larva as always greener than that of trifolii ; the full- 

 fed larva I have tried to describe most carefully, that 

 is to say, one variety of it like fig. 4, a ; of the other 

 varieties I cannot speak.
