62 BRITISH ICHNEUMONS. [Pinipla. 



The figures of both sexes closely resemble P. didyma, as also do the 

 economy and the Bombycid host ; but the present species is smaller, 

 more nitidulous with the abdomen in both sexes parallel-sided with the 

 mesopleura broadly rufescent. It is very remarkably like P. ovivora, Boh., 

 and if I had had an opportunity of examining the types before drawing 

 up my table of species, I should certainly have placed it next that insect, 

 under Tnvnatobia, 



" Twenty-three males and females of this unique species were bred 

 loth April, 1888, from a batch ot cocoons kindly sent to me by Dr. T. A, 

 Chapman, who obtained them from a larva of Pygacra curtula. This 

 batch of cocoons were so like a cluster of JMacroceniriis cocoons that Mr. 

 Bridgman at first sight could scarcely credit they were those of a Piiupla, 

 which, as a rule, are solitary parasites ; but fortunately one male died 

 ^\•ithin its cocoon, which 1 desired Mr. Bridgman to remove to make 

 certain that I was correct in ni)' observations, which he did, and he is 

 now able to vouch, if necessary, for the accuracy of my statement." ( Big- 

 nell, loc. a'L) Of these Mr. Bignell has allowed me to examine the one 

 female and two male co-types in his collection ; specimens were sent to 

 Bridgman and are presumably still in the Norwich .Aluseum ; the remain- 

 der became neglected and are destroyed. He has also presented me with 

 a pair of this species bred at New York from a spider, A. riparia ; and a 

 single male bred on 25th April, 1888, in South Carolina, from a spider's 

 egg-bag.
