254 LIST OP LEP1DOPTERA. 



of Suffolk/' were it not for the kind assistance rendered by two well-known 

 brother entomologists, the Rev. H. H. Crewe, and C. R. Bree, Esq., residing 

 in the same county. Owing to his long residence at Stowmarket, his accurate 

 and trustwoHhy observation, and his unwearied zeal, no person could be 

 found better qualified to impart information than Mr. Bree, and to him 

 accordingly it will be found that I am largely indebted. 



J. GREENE. 

 32, Lower Pembroke Street, Dublin. 



Part I. — Rhopalocera. 



1. P. Machaon. — Taken in the Rectory Garden at Erwarton, near Ipswich, 

 a few years since, and now in the collection of Miss Mary Berners. There 

 are some salt-marshes about half a mile from the Rectory, where the 

 insect would not be at all unlikely to occur. The Wild Fennel, (Fceni- 

 culum officinale, Bab.,) which is one of the food-plants of the larva of P. 

 Machaon, grows in the marshes. (C.) 



2. O. rhamni. — Not uncommon. 



N.B. — I am almost positive that Rhamnus catharticus and frangula, Linn, 

 are not the only food-plants of the larva of this insect, as both these 

 shrubs are exceedingly uncommon in the neighbourhood of Stowmarket, 

 where the perfect insect is abundant. R. frangula I have not yet seen at 

 all, and R. catharticus occurs most sparingly in solitary bushes. The larva 

 may be found of all sizes the last week in June and the beginning of July. 

 I have taken it abundantly in Kent on R. frangula, but never saw it upon 

 R. catharticus. It is not very difficult to see if you examine the leaves of 

 the former shrub tolerably close. It may also be beaten into an um- 

 brella. It feeds upon the upper side of the leaf. In appearance it closely 

 resembles the larva of Pieris rapce and napi, though it is of course much 

 larger. It is extremely easy to rear. The pupa is a most beautiful pale 

 green, without any spots. It is suspended in the same manner as the pupa 

 of P. brassier, rapce, and napi. (C.) 



3. Colias edusa. — Taken once in my own garden, and by Professor 

 Henslow at Felixstowe. (B.) 



Has been noticed at Battisford and Old Newton, near Stowmarket, by 

 Mr. William Baker and Mr. R. Bull. (0.) 



4. C. Jiyale. — Taken by Prof. Henslow at Felixstowe. (B.) 



A pair were taken, and several more seen, a few years since by Mr. 

 R. Bull, at Old Newton. (0.) 



5. Papilio brassicce. — Abundant. 



6. P. rapce. — Abundant. 



7. P. napi. — Abundant.
