British Braconida. 263 



i. ActATHIS (Latr.). 



Wesm., Nouv. Mem. Ac. Briix., 1837, p. 23. 



Maxillary palpi 5-, labial 4-joiuted. Face, maxillEe, and labium 

 produced, rostriforni. Mesotliorax distinctly trilobate. Mesopleurae 

 with traces of a longitudinal fiuTow. Three cubital areolets, the 

 first (as in Microdus) confused with the prsediscoidal. 



Viewed in front, the head is elongate -triangiilar, obtusely cari- 

 nated, with a fovea on each side above the labium ; face perpen- 

 dicular ; eyes naked, globose, prominent ; occiput obscurely mar- 

 gined. Body elongate. Abdominal segments 1 — 3 longer than the 

 rest taken together ; segment 1 slightly narrowed towards the base, 

 and rugulose ; 2 with a deep fovea at each hinder angle, between 

 which foveas is a gibbous space. Segments 2 and 3 marked with a 

 curved transverse impression, which in the small British species is 

 not very conspiciious. "Wings infuscated, with a decolorous streak 

 under the stigma, breaking the continuity of the nervures. The 

 wings being identical with those of Microdus, onlj- the form of the 

 head can be used as a divisional character. 



The Agathides are not common in this country. Only 

 28 specimens have come to my knowledge belonging to 

 two nearly-allied species, both of which have been bred 

 from Lepidoptera.
