T. D. A. COCKERELL. 219 



two yellow spots on disc, and a yellow apical band, interrupted in the 

 middle and enlarged on each side ; second segment with a yellow 

 apical band narrowed and evanescent medially, but enlarged to broad 

 triangles at sides, the enlargement being, however, nearly all on the 

 base of the third segment, and so not really part of the band ; third 

 to fifth segments with basal bands enlarged at sides and failing in the 

 middle ; apical dorsal segments with fuscous hair, but venter with pale 

 hair; apex truncate, the truncation tridentate or trituberculate, i. e., 

 with angular corners and a median tubercle ; venter mainly yellow 

 toward the base. 



9 . Similar, but antennal basin less evidently bounded ; upward 

 extension of lateral face-marks better developed, going broadly up 

 sides of front nearly to top of eyes, and enlarged opposite supraclypeal 

 area ; supraclypeal mark smaller ; scape merely reddish ; broadly tri- 

 angular area of metathorax black, the rest yellow; middle and hind 

 femora and hind tibiae dark, but the knees light; anterior femora 

 largely brown ; light parts of legs a sort of yellowish-testaceous ; first 

 abdominal segment yellowish with a broad suffused brown band ; 

 second segment with broad basal and apical pale bands ; fifth with 

 an apical band ; sixth light spotted ; sides of third showing a basal 

 band ; lower part of mesopleura dark. 



Had. Singapore {H. N. Ridley). British Museum. In 

 Bingham's table (Fauna of British India, Hymenoptera, 

 vol. 1, p. 500) this runs to C. moderata as nearly as anything, 

 but that is only half the size. It is, of course, related to C. 

 hieroglyph ica Smith, but is easily distinguished by the large 

 hairy wings, the great development of yellow on the face, 

 the large amount of yellow on the pleura, etc. By the yel- 

 low mandibles it is related to C. flavipes Smith, from China, 

 but that is a much smaller species. It is also related to C. 

 flavopicfa Smith, from Sarawak ; perhaps nearer to flavopicta 

 than to any other, but that has the basal and apical segments 

 of the abdomen, and the apical margins of the others, yellow. 



Ceratina samburueiisis sp. nov. 



9 . Length about or almost 10 mm. ; steel-blue and green, very 

 strongly punctured ; face below antenna? olive-green, with a very large 

 yellow hat-shaped clypeal mark, the crown of the hat broadest at the 

 top, cut off squarely, its breadth greater than the distance from either 

 corner to the eye, the basal lateral process thick and obtuse ; labrum 

 and mandibles black, the latter strongly curved, bidentate at apex ; 

 vertex blue, shading into the green of the cheeks ; scape and base of 

 flagellum chestnut-red ; thorax blue above, greener at sides; tubercles
