British Braconida. 167 



due to the large supply of materials, mostly bred speci- 

 mens, kindly contributed by many lepidopterists, to 

 whom we cannot sufficiently express our obligations. 

 Among these gentlemen we must specially mention 

 Bignell, whose whole collection, considerable in numbers 

 and admirable for its careful preparation, has long been 

 in our hands for examination. Eeinhard's valuable 

 papers in the Berl. ent. Zeit. (1880—81) have done 

 much to facilitate the study of this genus. They contain 

 a systematic revision of 59 species brought together 

 from the works of Haliday, Nees, Bouche, Wesmael, 

 and Eatzeburg. Of these 49 are here introduced as 

 British. To these are to be added 8 indigenous species 

 described by Haliday, but not known to Eeinhard ; all 

 these have been identified, with the exception of lineola. 

 A. persjyicuus, analis, scriceus, ^ees, and caics, Bouche, 

 have likewise been verified, and several new species 

 discovered. 



A synopsis of the species will be more intelligible if 

 we first divide them into sections, and then give a 

 separate table for each. 



Sect. I. — First abdominal segment subquadrate, seldom a little 

 longer than broad, truncate behind. Segment 2 as long 

 as 3, or nearly so. Terebra very short. Spp. 1 — 25. 



Sect. II. — First abdominal segment as in Sect. I. (except A. viini- 

 netorwm, Wesm., and exilis, Hal., where its length is 

 about double its breadth), seldom a little narrowed behind. 

 Segment 2 much shorter than 3. Terebra elongate, at 

 least \ as long as the abdomen. Spp. 26 — 53. 



Sect. III. — First abdominal segment about ^ longer than broad, 

 rarely more subquadrate, truncated behind. Segment 2 

 never much shorter than 8, impressed with two oblique 

 lines remote from the margins, converging to the base, 

 and enclosing a subtriaugular space. Terebra very short. 

 Spp. 54—58. 



Sect. IV. — Fnst abdominal segment attenuated behind, rounded or 

 lanceolate at the apex, at least twice as long as broad. 

 Segment 2 not much shorter than 3, with two oblique 

 impressed lines converging to the base, and enclosing a 

 siibtriangular space. Terebra variable. Spp. 59 — 69. 



In Sect. II. the males of the species with a shorter 

 terebra, and whose 2d segment is not so distinctly 

 shorter than the 3d, are liable to be incorrectly referred 

 to Sect. I.
