138 HYMENOPTERA FROM SARAWAK. 



scutellum is strongly, but not very closely, punctured : the post- 

 scutellum is more closely and regularly punctured. The basal 

 region of the median segment is closely punctured except the basal 

 lobes at the base. Legs black; the femora and tibiae thickly 

 covered with long pale, mixed sparsely with black, hair ; the 

 spines on the four front tibiie are bright rufous, on the hinder 

 black. Abdomen black ; the second and third segments have 

 distinct violaceous tints : the pubescence on the dorsal segments 

 are black, mixed with pale hair ; on the ventral segments the 

 hair is longer and paler ; the apex of* the petiole is strongly punc- 

 tured ; the rest of the abdomen smooth ; the segments are not 

 distinctly fringed with hair on their apices ; the stiff pile on the 

 pygidium is black mixed with white. 



Comes nearest perhaps to S.humeralis Sauss. which differs 

 from it in having the wings of a deep blue- violet tint ; in its 

 pronotum being broadly rufous ; in the mesonotum and scutellum 

 not being so strongly and closely punctured, the apical halves 

 of these being impunctate ; the abdominal segments want the 

 blue-violet tints and the abdomen is longer compared to the 

 length of the head and thorax. 



/ Scolia (Discolia) thyatira, sp. nov. 



Black; largely tinted with violet and purple tints; the

 antemite in the middle, an oblique broad mark on either side of 

 the top of the clypeus, the pronotum broadly above and a large 

 broad mark narrowed and rounded behind, on either side of the 

 base of the third segment, bright orange, the wings uniformly 

 fuscous-violaceous 5 .

Hab. Borneo. 



Antennee black, the scape, shining and covered with black 

 hair, the rlagellum opaque. The entire vertex, front, and the 

 upper part of the outer orbits, orange yellow ; strongly, but not 

 very closely, punctured, and covered rather thickly with long ful- 

 vous hair. The clypeus is more sparsely punctured and its apex 

 is impunctate ; the two orange marks are large, covered, and almost 

 unite above ; the hair on the face is black, on the clypeus pale. 

 The hair on the thorax is dense, stiff and black ; the punctuation
