Rhaphitelini. 



Oluspa, gen. now 



Head wider than the thorax, the eyes large, longish oval, parallel, not 

 converging, widely separated ; the ocelli placed in a curve, the hinder on the 

 edge of the vertex ; occiput almost transverse, the temples very little developed: 

 imlar space two-thirds of the length of the eyes. Antennas placed almost 

 in the middle of the face, opposite the end of the eyes. The front is very 

 little depressed, the antenna! furrow shallow, narrow. Antennae 12-jointed 

 the scape does not reach to the ocelli ; the pedicle is more than twice longer 

 than wide, the ring joints narrower than it and half its length ; the apical 

 joints do not form a club. Pronotum distinct, clearly separated from the meso- 

 notum, which has weak, oblique furrows on the basal half. Scutellum large, 

 nearly one-half longer than wide, the base transverse, bordered in the middle 

 by a wide furrow; the apex broadly rounded. Metanotum keeled down the 

 middle ; the sides see 1 from above form large triangles. Abdomen sessile, 

 as long as the thorax, the apex narrowed to a sharp point Base of meso- 

 pleurte depressed to near the middle, the raised apical part with a triangular 

 depression above the middle. Legs normal ; the spur on the hind tibiae 

 distinct. Wings shortly ciliated round the edges, the marginal nervure 

 about one-third shorter than the basal, which is dilated at the apex ; the post- 

 marginal is slightly longer than the stigmal branch, which is a little dilated 

 at the apex. The front femora are thicker than the others, especially in the 

 middle. The clypeus forms a depression, rounded above ; the apex transverse ; 

 there is a keel in the middle of the face. 



Belongs to the Rhaphitelini — I cannot refer it to any of the described 

 genera in that group In Ashmead's system it runs near to Rhaphitelus. 

 The occinut is narrower, more transverse and the temples less developed than 

 in that gi oup. the 2nd abdominal segment is smaller being not much longer 

 than the 3rd. Characteristic are the ocelli placed in a curve on the extreme 

 outer edge of the vertex. 



Oluspa albopilosella. sp. n. 



Dark blue, the head and upper part of thorax darker, more bronzy in 

 tint, the back of the abdomen except round the edges dark bronzy ; the 

 antennal scape and pedicle rufo-testaceous, the rest of the flagellum dark 

 fuscous, densely covered with white pubescence ; the head and upper part 

 of pro- and mesothorax with the scutellum sparsely covered with distinct 

 thickish white hairs ; legs whitish yellow, the four front coxae blackish except 

 at the apex, the hinder metallic blue, the four front femora largely fuscous 

 above and below, the hinder black, tinged with blue from the base to near the 

 apex; wings hyaline, the nervines pallid testaceous. Female. Length 2. mm, 



Bred from pupae found in fruit of Cardiospermum halicncabum, Head 

 finely, dlosely, regularly punctured, the occiput finely closely transversely 

 striated, the striae roundly curved. Propleurae smooth, the depressed base of 

 mesopleurae finely, regularly, closely reticulated, the lower apical part more
