This species is very distinct from H. gyrini described in the Ent. 



f Mo. Mag., vol. xviii, p. 79, and is, so far as can be ascertained, imde- 

 scribed. It was bred from some pupae of Gyrinus natator, collected 



1 by the Rev. J. liellins at the same time and place as stated before in 

 regard to gyrini, but this did not come out so soon as that species, and 

 consequently was not described nor in time for my catalogue of Ichneu- 

 monidce of Devonshire. This insect has the facies of gyrini, but it 



i has the basal half of the antennae red, and the thorax is quite smooth 

 without any lines or markings, and the abdomen is broadly ovate, all 

 of which distinguish it from the former species.

NOTES ON BEITISH TORTRIGES. 

 BY C. G. BARRETT. 



(continued from p. 154). 



On page 241 of Vol. xiv of this Magazine are some remarks upon 

 a supposed aberrant form of Brachytwnia Hartmanniana, L. (scrip- 

 tana, H.), found by Dr. "Wood in Herefordshire in the year 1877. 

 During the succeeding three years, although constantly looked for, it 

 was not seen ; but Dr. Wood's unflagging zeal has been rewarded this 

 year by the capture of nearly a dozen specimens. These he has sent 

 for examination, pointing out their perfect constancy in shape, colour 

 and marking, and the reliable marks of distinction from Hartmanniana, 

 which is well known to be little liable to variation, and strongly urging 

 the claim of this form to rank as a distinct species. 



I am inclined to think that the claim is good, and, therefore, pro- 

 pose to name this pretty species after the entomologist who has 

 devoted so much time and pains to working it out. 



BBACHTTiE^IA WOODIANA, 11. SJ).

 iStreaks short, blue -grey. Beyond the central fascia are three delicate curved lines of
