resembles X€stophanespotentilke,hu.t the caciculated mesotliorax forms 

 a ready mark of separation. 



In the form of the thorax and abdomen it resembles Ceroptres, 

 but then the antennre are not thickened at the apex. I have 

 compared my species with the descriptions of all the species of 

 Ceroptres, but have not been able to find one with which it will 

 agree.'"' 



From the A ulax I bred two species of Chalcididse, viz., a species 

 of Eurytoma and a Decatoma. Of the former I bred only a male 

 and female ; and the species seems to me to be undescribed, but 

 further investigation is necessary to confirm this. The Decatoma 

 was more numerous, and both sexes were represented. It is, I 

 believe, D. higuitata, Swecl., — not, certainly, agreeing with the 

 type of that sj)ecies ; but, if the descriptions of D. Cooperi, Curt., 

 ohscara, and immaculata, Wlk., and signata, Nees (which are merely 

 varieties of biguttata), be combined with that oi higuttata, then our' 

 species will fit in with the united descriptions. 



According to Foerster (Beitrage zur Monder. Pteromalinen, p. 6), 

 the typical biguttata is a parasite in oak galls, viz., in those of 

 Aphilothrix gemmce, Dryoteras terminale, and a Neuroterus. 



I likewise got in the centre of a root tenanted by the Aulax, the 

 full-fed larva of a beetle, Tachinus rufipes. Whether it actually 

 fed on the root or on the Aulax larvae, or had merely retired there 

 for the purpose of passing into the pupa state, I cannot say. 



The Kev. T. A. Marshall, in his excellent article in the " Ento- 

 mologist's Annual " for 1874, by giving a list of thirty-nine British 

 species of parasitic Cynipidae, has furnished us with a stand-point 

 from which to record further discoveries. On working up my 

 captures in this family, made during the last two years, I find 

 that I can add the following species to our British list; and 

 I am persuaded that this by no means closes my number of 

 novelties. I appear to have several new species, notably a very 

 small species of Eucoila, taken at an elevation of about 3500 feet, 

 on one of the Breadalbane mountains.

* I may take this opportunity of adding the genus Ceroptres to the British 

 fauna, having bred C arator, Hartig (Germ. Zeits., 1841, p. 343), from galls of 

 A ndricus noduli, found at Kenmuir bank, and also on the Cambuslang side of 

 the Clyde.
