2. Apanteles lineola, Cur. (Hal.). 



Microfjaster lineola, Cur., B. E., 321, No. 11; Hal., 

 Ent. Mag., ii., 252, ^ . 



" Male. Thorax very minutely piinctulate ; femora and tibiae 

 flavo-testaceous ; 4 posterior femora on both sides, and their tibiae 

 at the apex, fuscous ; wings whitish ; segments 1 — 3 aciculated." 



" Size of M. glomeratus ; palpi yellow ; legs coloured nearly like 

 those of M. immunis; stigma and nervures in the middle of the 

 wing pale feiTUginous, the rest decolorous ; squamulae black ; 

 metathorax punctato-reticulate ; abdomen unusually short and 

 broad, segments 1 — 3 punctato-reticulate ; the 1st short, broad, its 

 apical angles hardly margined with yellow." 



I have not seen this msect, and the above is a trans- 

 lation of Halicla3''s description. It must be nearly allied 

 to the preceding species, if not the same. Eeinhard 

 hesitated in joining them on account of their different 

 habits, lineola having been bred from a dipterous insect, 

 Sijrj^hiis pi/nistri, L. As this fact appeared doubtful to 

 Eeinhard, I shall quote the words of Curtis in ' Farm 

 Insects,' p. 81 : — "The maggots" [of S. pi/rastri] "are 

 green, and I found them in July, 1829, in some abun- 

 dance on the sea-cabbages, Brassica oleracea, ■which grow 

 under the cliffs near Dover. Many of them had been 

 stung by a little parasitic fly, called Microciaster lineola, 

 the maggots of which came out of the Scceva larvae, and 

 formed little elliptical silken cocoons almost white." In 

 1884 I searched for the Syrphus-\?iX\ie in the Isle of 

 Wight, but could only obtain one, which produced a 

 dipterous imago. These larvae are grass-green, with a 

 black dorsal stripe, common among Aphides on the 

 south coast, and easily reared. It is to be hoped that 

 some entomologist before long will obtain from them 

 A. lineola. In "Walker's collection, at Oxford, are two 

 females and one male, numbered 104, ticketed lineola ; 

 but I have not been able to examine them.
