20G [ September, 



collected several galls from the male catkins on May I4th and 20th, the 

 flies emerging May 26th to 28th, 1895. Parasite, PteromaUis tibialis, 

 bred June 12th. 



Andhicus glandule. — On October 3rd and 17th, 1890, these 

 galls were abundant in Cann Wood. In the galls that I examined on 

 the 17th the larvse were full fed in the upper part, lower cavity empty ; 

 I bred a number of inquilines {Synergus radiatus) May 1st, 1891, and 

 following days. I examined a few galls in January, 1892, and found 

 perfect flies, those not disturbed emerged in April. The last sentence 

 but one on page 102 of Cameron's Eay Soc. Vol. on the Oak Galls, 

 should read — "The insect emerges in the spring o/'M^' second year." 



Andricus solitartus.— I can confirm Dr. Mayr's statement that 

 the flies emerge in September, having beaten them out of oak in Tann 

 Wood on September 29th, 1890. 



Neuroteeus lenticularis on page 131 of Cameron's work, 8th 

 line from bottom, after " April," read "The eggs of the ay amic female 

 are laid, &c." 



Neuroterus (Spathegaster) tricolor. — I have bred two para- 

 sites from this species, Torymiis auratus and Pteromalus tibialis. 



Neuroterus (Spathegaster) albipes.— The only parasite I have 

 bred from this species is Pteromalus tibialis (not recorded by Cameron). 



Neuroterus (Spathegaster) vesicatrix.— Out of fifty galls 

 collected in May and June this year (1895) I have not bred a single 

 maker, the majority contained inquilines (Si/neryns albipes), in some 

 instances two in a gall, and as usual separated by a slight partition ; 

 the remainder produced parasites (Pteromalus tibialis). 



Neuroterus (Spathegaster )aprilinus. — The quick development 

 of this species is something truly wonderful. The first gall seen with 

 difficulty, just appearing out of the bud, was on April 29th, it was 

 fully developed, and the fly emerged on May 2nd ; only collapsed and 

 shrivelled galls were seen on May 6th. In the middle of May (17th) 

 I discovered a tree with a lot of shrivelled aprilinus galls, and on May 

 23rd I found galls of Neuroterus Schlechtendali mature and ready to 

 fall to the ground on the slightest touch ; this gall was only observed 

 on the same tree that produced the aprilinus galls. It will be inter- 

 esting if Schlechtendali proves the agamic form of aprilinus. 1 trust 

 I shall be able to decide this in 1897, as I have some hundi*eds of 

 Schlechtendali galls ; unfortunately the flies do not appear until July 

 of the second year.
