British Braconidce. 63 



V. HECABOLIDES. 



Established by Forster to include those forms of the 

 Cyclostomi which have only two cubital areolets. Of the 

 ten genera enumerated (Verb. pr. Eheinl., 1862, p. 236) 

 only five refer to described types ; the others must be 

 consigned to the limbo of MS. names. After the sub- 

 traction of Pambolns, which appears too widely aberrant 

 to find a place here, there remains, belonging to the 

 British Fauna, the single genus — 



Hecabolus, Cur. 



Cur., B. E., 507 (1834); Hal., Ent. Mag., iv., 48 

 (1836). 



Head cubical; abdomen subsessile, the segments discrete, suturi- 

 form articulation faintly marked; terebra J elongate; fore wings 

 with two cubital areolets ; hind wings of the ^ with a stigma 

 near the base ; the recurrent nervure, but not the anal, interstitial. 



1. Hecabolus sulcatus, Cur. (PL II., figs. 4, 4a). 



Hecabolus sulcatus, Cur., B. E., pi. dvii ; Hal., Ent. 

 Mag., iv., 48 ; Eatz., Ichn d. Forst., ii., 34, pi. ii., 

 fig. 11 (wings <? ) ; iii., 32 ; S. v. VolL, Schets., 

 ii., tab. 6 (where the striolae on the base of the 3d 

 segment are not represented). 



Anisopclma Belqicum, Wesm., Nouv. Mem. Ac. Brux., 

 1838, p. 134, pL, fig. 17 (wing), ? . 



Black, the abdomen pitchy; palpi pale; antennae at the base, 

 and legs, testaceous ; femora, tibiae in the middle, and hind coxae, 

 more or less fuscous ; intermediate tarsi very short ; abdominal 

 segments 1 — 2 depressed, and, together with the basal half of the 

 3d, striolated longitudinally, the rest of the abdomen smooth 

 wings hyaline, stigmata fuscous ; terebra $ longer than the body 

 Length, 1— 2| ; wings, 1|— 3i lin. <? ? . 



Antennae ? shorter than the body, 19 — 26-jointed ; of the (? 

 hardly as long as the body, 21-, 22-, 25-jointed, in 3 examples. 



The abdomen of the ? is clavate, of the 3" hnear-lanceolate. 

 The stigma of the hind wings in the 3 almost fills up the costal 

 and prsebrachial areolets, and is about half the size of the fore- 

 stigma : no other British Braconid possessing this character is at 

 present known. Like other parasites of xylophagous insects, it 

 varies much in size ; the 3 is always smaller than the $ .
