202 Eev. T. A. Marshall's mo7iograph of 



Andricus multiplicatiis, Gir. But according to Giraud 

 (Verb. z.-b. Ges. Wien., 1859, p. 360), EpMppiophora 

 costipunctana, Haw., occurs frequently in the same galls. 

 It is therefore more probable that the Apantcles is a 

 parasite of the moth, than of the Cynips. A solitary 

 parasite. Cocoons glossy white.

Black ; palpi fiiscoiis ; fore tibiee, fore femora at the apex, middle 

 and hind tibiae at the base, flavo-ferruginous. "Wings white, stigma 

 nigi-o-piceoiis, nervui-es m the middle testaceous, elsewhere de- 

 colorous ; costa pale at the base. Thorax pmictnlate, shming. 

 Segment 1 half as long again as broad, trnncate, margined, with 

 parallel sides, slightly aciculated; segment 2 short, broader than 1, 

 and, with the following segments, smooth and shining. Terebra 

 i as long as the abdomen, valves slender, scarcely curved. ^ J . 

 Length Ij ; wings 3 hn. 



Similar to the last species, but smaller : the 1st 

 abdominal segment is narrower, the terebra shorter, and 

 not clavate. 



Common in the Isle of Wight in August ; Devonshire ; 

 Northants ; Kent, &c. Bred by Bignell from Tortrix 

 Forsierana , Fab., three males, two females. According 

 to Eatzeburg, obtained from apple-blossoms inhabited 

 by a Curculio, Anthonomus p)omorum, L. According 

 to Eeinhard, from GracUaria sy ring ell a, Fab., and from 

 the heads of thistles. Brischke reports that he bred 

 this species from Lyccena Corydon, Fab., and Eupithecia 

 sobrinata, Hub. ; the cocoons are described as single, 

 and woolly, that from the Lyccena white, from the 

 Eupithecia, yellow; a difference which seems to indicate 

 some confusion of species, for no Apanteles of this 

 section makes yellow cocoons. Cocoons white, with a 

 satiny gloss, like those of alhipennis, Nees ; several joined 

 together by a few threads.
