LIST OP LEPIDOPTERA OCCURRING IN THE COUNTY 



OF SUFFOLK. 



BY THE REV. JOSEPH GREENE, M.A., ASSISTED BY THE REV. H. HARPUR CREWE, M.A., 



AND C. R. BREE, ESQ. 



[The portions of these papers contributed by Mr. Crewe and Mr. Bree, are signed with the 

 initials C and B respectively. N.B. at the head of a paragraph signifies that the remarks 

 are made after those of Mr. Greene.] 



( Continued from page 60.) 



48. P. lacertula. — Rare. A few specimens by beating. 



N.B. — This moth is double-brooded, appearing in May and June, and again 

 in August. The larva may be beaten from birch in July, and again in 

 September and October. I have taken it both in the woods near Ipswich 

 and in this neighbourhood. When full-fed it unites the edges of a leaf by 

 a very strong web, and turns to a pale red pupa covered with a white bloom, 

 like that of C. diffinis. (C.) 



49. P. falcula. — Common. The larva feeds on birch and alder, and the 

 insect is double-brooded. 



N.B. — The larva of this insect is pale green, with a broad reddish dorsal 

 stripe, and is studded with small tubercles, or rather spiculse. Like that of 

 Lacertula it spins the edges of a leaf together with a strong web, and turns 

 to a dark chesnut brown pupa, somewhat similar to that of C. duplaris. (C.) 



50. P. hamula. — One beaten from oak. 



N.B. — Taken at Ringshall and Battisford, by Mr. W. Baker. It is double- 

 brooded, appearing at the same time as P. lacertula. (C.) 



51. P. unguicula. — Taken by Mr. W. Baker, at Ringshall and Battisford. 

 (C.) 



52 and 53. C. farcula and bifida. — Not very common, that is, not very 

 commonly found, though empty cocoons were in profusion. 



N.B. — Mr. W. D. Crotch, in his amusing paper at page 52, No. 59, of the 

 "Intelligencer," says that he found the cocoons of both these insects on 

 poplar. Now I have been in the habit of taking both egg and larva of 

 both species for some years past, and have found furcula upon every species 

 of willow and sallow, and vice versa, bifida upon poplar, but I never found 

 the former upon any species of poplar, or the latter upon willow and sallow, 

 and I no more believe that they ever desert their respective trees, than I 

 do that the larva of N. dictcea ever feeds upon birch, or N. dictceoides upon 

 poplar. I have not unfrequently found the cocoons of C. vinula upon the 

 trunk of an oak, but I never for a moment supposed that the larva had 

 fed upon that tree, and have always found either a poplar, sallow, or willow 

 close at hand. If there were any sallows or willows near Mr. Crotch's poplar, 

 I can easily account for his finding the cocoons of both species on the same 

 tree, but otherwise I am at a loss to do so. It is worth while looking for
