Catalofiiie of British Ichneumonidce. 143 



Lane ; when I first saw it I thought it was a variety of 

 /. eri/thrmis, but there is no doubt it is distinct from 

 that insect. I thought it was the same species Wesmael 

 described in his ' Tentamen,' p. 102, as I. discrepator. 

 Mr. Bilhips had only taken the female ; but Dr. Capron 

 has since sent me a male Ichneumon for my opinion, 

 which certainly is the male of /. discrepator, and this 

 strengthens my belief that the female also belongs to 

 the same species ; so the synonymy of this species appears 

 to be — 



Ichneumon, sanguinator, Eossi, Mant. ii., app., n. 85 ; 



Gr., I. E.'iii., 918, ? . 

 /. ruficollis, Steph,, 111., Mand., vii., 207. 

 I. discrepator, Wesm., Tent. 102, <? , ? . 



Mr. Fitcli saw a series of this insect in the British 

 Museum, and called my attention to it ; to him my thanks 

 are due for the correction of the error.

This genus is new to Britain ; one female was taken 

 by Mr. G. C. Bignell at Plymbridge, near Plymouth. 



CEYPTID^.' 



Cryptus palustris, Thorns. 



The male Cryptiis, which I thought might belong to 

 this species, is, I have no doubt, the male of Cryptus 

 ornatus, Gr., described by Thomson in his ' Opuscula,' 

 p. 506. Cryptus ornatus is given by Marshall as a 

 synonym of C. tricolor, but Thomson [1. c.) makes them 

 separate species, as Gravenhorst did, and the same 

 course is adopted by Bi ischke. 



Ilemiteles castaneiis, Tasch. 



Mr. Bignell has bred two males and one female of this 

 species from TricJtiosoma hetuleti, and as I know no de- 

 scription of the male I now give one.
