striated , those on the basal fourth strong and widely separated 

 and more or less transversely striated between the longitudinal 

 Striae ; from these the striation becomes gradually weaker to the 

 apex. There is a small testaceous spot on the sides near the 

 base. Legs (and more particularly the tibiae and tarsi) covered 

 with white pubescence. 



Spathius leptoceras sp. nov. 



Testaceous, the legs paler coloured, the back of the abdomen 

 and the apical half of the hind femora black, the antennal scape 

 testaceous, the flagellum black, with the apical 10 or 12 joints 

 testaceous ; wings hyaline , suffused slightly with fuscous , the 

 stigma black , pale at the base , the nervures black. Antennae 

 long , when turned back reaching beyond the middle of the ovi- 

 positor, densely covered with stiff blackish pubescence. §. 



Length 6 mm, terebra 4 mm. 



Kuching, Borneo (John Hewitt, B. A.). 



Face somewhat strongly transversely striated , the striae 

 more or less intertwining , more strongly striated laterally than 

 in the middle. Middle lobe of mesonotum closely, rugosely punc- 

 tured , the rest coarsely irregularly reticulated. At the base of 

 the scutellum is a wide, deep transverse furrow, extending beyond 

 it and with its outer edges narrowed ; the base of the scutellum 

 is depressed , coarsely reticulated and bordered by an oblique 

 keel , which cloes not extend to the middle ; the central part is 

 smooth, the apical punctured. Base of metanotum finely, closely 

 transversely striated and with a keel down the centre, the middle 

 coarsely reticulated , the apical slope black , with 2 stout keels 

 doAvn the- middle, forming an area; between the longitudinal keels 

 are stout transverse ones ; on the sides are some stout, irregulär 

 oblicrue keels. Propleurae in the centre stoutly striated ; the 

 mesopleurae smooth , except at the top half which is stoutly 

 longitudinally striated, the apex also having some, clearly separated 

 stout longitudinal striae. Metapleurae stoutly obliquely striated 

 above , more weakly below ; above the centre are 2 longitudinal 

 keels ; the space between them is stoutly striated , the striae 

 distinctly separated and running from the top to the bottom. 

 Abdominal petiole longitudinally rugose , the sides above keeled, 

 outside which , on the apex , are 3 or 4 finer striae , the outer- 

 most being much shorter than the others ; laterally it is rugosely 

 punctured to shortly beyond the middle ; the apical part stoutly 

 striated. As usual the legs are covered with stiff pale hairs. 

 The ovipositor is as long as the abdomen.
