110 HYMENOPTERA OF SARAWAK. 



parts. Metanotum areolated irregularly reticulated, the 

 longer than broad, Mesopleurae smooth, punctured above and 

 below. Metapleurae closely rugose. Basal segment of abdomen 

 irregularly longitudinally striated. The hinder femora are serrate 

 beneath in the middle, the teeth not being well developed. 



Enagathis erythrocephala, sp. nov. 



Black, the scape of antennae, head, pro- and mesothorax red, 

 the fore legs of a less clear red, the middle coxae from near the 

 base, trochanters and femora, fuscous-black, the rest of the legs 

 of a dark red ; wings fuscous-violaceous, paler on the costal 

 cell, the nervures and stigma black, 9 . 



Length 8-9 mm ; terebra 1 mm. 



Hab. Kuching. January. 



Scape of antennae covered with white, the flagellum thickly 

 with stiff, pubescence. Front and vertex smooth ; a curved 

 oblique furrow above each antenna. Pace distinctly punctured, 

 roundly dilated in the middle ; the clypeus less strongly punc- 

 tured, deeply foveate at the sides. Mandibles rufous, palpi 

 rufo-testaceous. Prothorax impunctate ; the mesothorax punc- 

 tured, but not closely or strongly, the scutellum more strongly 

 punctured ; scutellar depression deep, with 2 stout keels in the 

 centre; scutellum roundly convex, with a bordering keel on its 

 apex below ; post-scutellum bordered by a stout keels and with 

 a stout one in the centre. In the centre of the metanotum, at 

 the base, is an area, fully twice longer than wide, transverse at 

 the apex, gradually narrowed towards the base, with the keels 

 curved ; outside this is another area of nearly equal width ; on 

 the sides are some irregular striae, especially at the apex. The 

 apical slope is bordered above by a keel and has a few stout 

 longitudinal keels. The long spur of the middle leg is nearly 

 as long as the basal joint of the tarsi. Abdomen smooth and 

 shining. 



Apart from the difference in colouration, etc., this species 

 may be known from \E. creophora by the long spur of the mid- 

 dle tibiae. In the latter species it is short as usual.
