HYMENOPTERA OF THE BOMBAY PRESIDENCY. 657 



I cannot separate it from the latter genus. Its generic location may, in 

 the meantime, be left over, until the $ has been discovered. 



Thaumatnsoma testaceicome, sp. nov. 



Black, the antenna? except the scape and apical joint testaceous, darker above, 

 the pubescence dense and white, the puncturation strong and close ; the apical 

 abdominal segment curved downwards, entire, broadly rounded, the outer edges 

 straight, oblique ; metanotum roundly convex, smooth, shining, bare, the base 

 with a striated border, keeled before and behind and much widened laterally. 

 Basal segments of abdomen testaceous below. The pubescence on the lower part 

 of the head is much longer and denser than elsewhere, especially behind. The 

 hair on the underside of the apex of the 4 posterior tibia? and, to a less extent, 

 on the anterior, is long and dense, as it is also on the base of the tarsi. 

 Mandibles with the apical tooth distinctly separated ; there is no distinct sub- 

 apical one. The joints of the flagellum to the flattened apical one are of equal 

 thickness ; the last is long, dilated and flattened. First recurrent nervure inter- 

 stitial : the 2nd received near the apex. £ . 



Length 7 mm. 



Matheran, May (Nurse). 



There are 2 points in which the known Indian Thatimalsoma (T. burmanicum , 

 Bing.) differs from that here described : the apex of the abdomen ends in a 

 longish central and a smaller lateral tooth and the 4 sub-apical joints of the 

 antenna? are attenuated and filiform as compared with the preceding joints. 



Ceratina spilaspi*, sp. nov. 



Green, the abdomen dark brown, the following parts bright yellow : clypeus. 

 labrum, mandibles, except at the apex, underside of scape, a line on the prono- 

 tum uniting with the tubercles, the latter, tegula?, a mark on the sides of the 

 scutellum, post-scutellum broad lines on the sides of the 2nd and 3rd segments 

 at the base, straight and twice the width of the central part, a narrow, almost 

 continuous line on the 4th, a broad, curved one on the 5th roundly narrowed in 

 the middle on the 5th, the apex of the femora narrowly, the tibia? and the tarsi, 

 bright lemon-yellow, the hind tibia? broadly black at the apex ; the hair white 

 on the body and legs ; wings clear hyaline, the nervures, costa and stigma pale 

 yellow. $. 



Length 6 mm. 



Deesa, April. 



Underside of flagellum pale brown or fulvous. Clypeus with a few strong 

 punctures in the centre ; the face more finely and more closely punctured. 

 Mesonotum finely, closely punctured ; there is a distinct furrow on the sides 

 opposite the tegula?, the scutellum bears scattered punctures in the centre ; the 

 base of metanotum is much more strongly, regularly and closely punctured ; its 

 apical slope is smooth. Abdomen shining, impunctate. There are 2 obscure 

 lines on the apex of the clypeus. 



This species is not unlike C. divisa. Cam.; the latter may be known from it 

 by the transverse yellow line on the apex of the mesonotum. by the lines on the
