ON THE BRACONIDOUS CRYPTOGASTRES. 183 



Piffard took several from Felden, in Herts ; and I swept, on 

 28th August, 1906, a specimen in Tuddenham Fen, Suffolk. 



A. rufidens. — A common species, taken by Dalglish at Irvine 

 and Bishopton in July; by Piffard at Felden; by Eev. E. N. 

 Bloomfield at Guestling, in Sussex, in 1877 ; and by myself on 

 umbelliferous flowers at Bildeston, in Suffolk, 30th July, 1898. 

 This species has the clypeus apically tridentate, and not, as in 

 A, canifrons, obsoletely unidentate centrally. 



A. variipes. — Not uncommon in damp spots. I took it in 

 Wicken Fen, Cambridgeshire, 8th June, 1902 ; in Henstead 

 marshes, Suffolk, by sweeping, 3rd July, 1906 ; and possess 

 others from Felden, in Herts. 



A. armatus. — A rare and conspicuous species, of which I have 

 only seen two examples, both taken in August ; one at Reigate in 

 1872 by Wilson Saunders, and the other by myself in Mr. Adams's 

 garden at Lyndhurst, on 8th, 1901. 



A . quadridentatus. — Very common. Mr. E . R. Bankes has thrice 

 bred it : nine specimens emerged at Corfe Castle, Dorset, between 

 June 20th and July 4th, 1901, from larvse of Sericoris bifasciana; 

 one emerged in the same locality on June 26th, 1901, from (pro- 

 bably) Acrolepia granitella ; and between May 4th and 25th, 1900, 

 sixteen were bred from larvae of Lozopera francillonana, in stems 

 of Ferula communis collected at He St. Marguerite, Cannes, by 

 Chapman the preceding spring. I have thrice received it from 

 Dr. Chapman. On the first occasion (1st June, 1900) about 

 twenty were bred, with a single male of Bracon pectoralis, Wesm., 

 from Lozopera francillonana at Cannes ; secondly (29th April, 

 1900), one emerged from the larval case of Psyche tenella var. 

 zermattensis at Locarno or Cannes in March or April ; thirdly 

 (2nd May, 1900), one was bred at Cannes from the first-named 

 host; and, lastly (17th May, 1901), a single specimen emerged 

 from a larva of both Lozopera deaurana and of L. francillonana. 

 Tuck has captured it at Tostock, in Suffolk, 20th July, 1900 ; I 

 have found it on umbelliferous flowers at Grundisburgh on 25th 

 July, 1898, and swept it in Bentley Woods, 15th June, 1895 ; 

 Wilson Saunders found it at Greenings, in Surrey, in June, 

 1871 ; and Col. Yerbury, at Nairn, on 7th June, 1904. 



I have not met with the only British species of Alloderus — 

 lepidus, Hal.— which may be known from the three other palee- 

 arctic species by its rugose third segment, which is not centrally 

 carinate, and by the antennae being at least 29 -jointed, with the 

 terebra as long as the abdomen.
