90 SPOLIA ZBYLANICA. 



transverse nervnre to the apex of the hind wings. These genera 

 may be separated as follows : — 



(a) Hind coxae with two teeth... Acanthobr aeon, Cam, (Szep.). 



(b) Hind coxae toothless. Apex of mandibles stoutly 



toothed ; sides of median segment toothed at the sides 



above the apex, the scutellum conx ex... Trichiobincon, 

 Apex of mandibles not toothed, transverse ; sides of 



metanotum not toothed above ; the scutellum quite 



&2it...Holcobracon. 

 These three genera form a natural tribe, Holcobraconini, allied 

 to Doryctini, which should be readily known by the hind 

 wings haviug three longitudinal nervures running to the apex 

 of the wings ; the abdomen sessile, the mesopleurae with a 

 distinct crenulated furrow along the lower border, the metanotum 

 toothed or tuberculated above or below, closely reticulated and 

 the basal three segments of abdomen longitudinally striated, 

 with a distinct curved crenulated suturiform articulation and 

 oblique furrows as in Iphiaulax, and stoutly toothed fore tibiae.

Plate A, fig. 6. 



Rufo-fulvous, the antennae black ; wings yellowish-hyaline to 

 near the apex of the transverse basal nervure, with an oblique, 

 irregular cloud in the first cubital cellule, extending below into 

 the discoidal ; the stigma luteous ; hind wings yellowish-hyaline, 

 the apical third smoky, 9. 



Length 18 mm. 



Kandy, November. 



Body and legs thickly covered with long pale pubescence. 

 Face and oral region closely, finely rugose, thickly covered with 

 fuscous pubescence, the clypeus with long fuscous hair. Front 

 and vertex smooth, shining, almost bare. Pronotum punctured, 

 the punctures large, clearly separated, and each with aJlongish hair. 

 Mesonotum and scutellum smooth, sparsely haired. The scutellar 

 depression with five stout keels ; the central the larger. Metano- 

 tum with a keel down the centre, closely reticulated, the 

 reticulations shallow, irregular in shape, some hexagonal. The 

 centre of propleurae with some irregular keels. The lower furrow 

 on the mesonotum closely crenulated ; the oblique furrow below 

 the tubercles wide, deep, and with some stout keels. The upper 

 part of the metapleurae irregularly, coarsely reticulated ; below the 

 furrow strongly, irregularly punctured. Legs thickly covered 

 with long pale pubescence. Basal three segments of abdomen 

 strongly closely striated ; the suturiform articulation deep,roundly
