EVANIID^E. 



34. Evaiiia Haarupi sp. n. 



Head, thorax and hind coxae, except at the apex, red, the rest black ; 

 wings clear hyaline, the nervures black ; the apical joint of the tarsi 

 of a dark red color ; the hind spurs fuscous. Head, thorax and legs 

 covered with a white down. Sides of the face and the top finely closely 

 striated ; the central part of the face with a few scattered punctures 

 and bordered laterally by a deep, slighty curved furrow. Centre of 

 front with a clearly defined keel ; the part on either side of this finely 

 closely obliquely striated, the outer side with large, clearly separated 

 punctures. Vertex smooth, except for a few punctures outside the 

 ocelli, which are in a curve, the hinder being separated from each 

 other by the same distance as they are from the eyes. Metasternal 

 fork with diverging branches. 9 . Length 4.5 mm. 



Antenna; long, the apex reaching beyond the apex of the abdominal 

 petiole, slightly thickened towards the apex ; covered with a white pile ; 

 the third joint not much longer than the fourth ; the underside of the 

 flagellum fuscous. Malar space nearly as long as the eyes. Apex of 

 the mandibles and the teeth black. Centre of mesonotum strongly 

 punctured in the centre, the punctures widely separated ; the outer edges 

 much more weakly and sparsely punctured. The scutellum is much 

 more strongly punctured than the mesonotum ; the metanotum is reticu- 

 lated, more finely, irregularly and closely on the apical slope in the 

 centre ; the part between the metanotum and the pleurae is obliquely 

 striated, with a keel down the middle. Abdominal petiole shining, 

 sparsely punctured ; above it bears on the sides two stout longitudinal 

 keels and, at the apex below, is a shorter one. Propleurse at the apex 

 above broadly obliquely striated, the striae becoming shorter below; 

 the lower depressed middle part is strongly longitudinally striated. 

 The long spur of the hind tibiae does not quite reach to the middle of 

 the metatarsus.

35. Evaiiia meiiclozaeiisis sp. n. 



Black, the antennae and legs red, the coxae, apical half of hind joint 

 of middle trochanters, the greater part of the hinder and the hind tarsi, 

 black ; wings hyaline, the nervures black. Face densely covered with 

 white pubescence, smooth, a fine furrow down the sides. Front 

 strongly but not very closely punctured, a fine keel down the centre. 

 Vertex with some scattered punctures ; Jthe temples smooth. Hind 

 ocelli separated from each other by a distincly greater distance than 

 they are from the eyes. Malar space one-third of the length of the
