apex transverse. Abdomen almost nniformly, closely punctured. 

 Apical abscissa of radius roundly curved below, straight, slig^itly 

 oblique above ; the apex of cubitus roundly, broadly curved 

 in the middle. The spur of fore tibiae is roundly curved ; its 

 apex is straight, slightly oblique. The transverse basal nervure 

 is sharply oblique and elbowed below. 



This species may be the cT of D. nitida Smith from Key 

 (or Ki) Island ; but the Smithian descriptions are not very 

 good. The 2"'' radial cellule is larger, broader, compared with 

 its length than usual, than in e. </. D. Vollenhoveni or D. capitata. 



Dielis javanica Lep. 



Apparently a common species. Batavia. (Van Nooten leg.) ; 

 Borneo. 



Dielis sericepft sp. nov. 



Black ; the hinder part of the vertex, hinder orbits broadly 

 and pleuree thickly covered with dark silvery sericeous pubes- 

 cence ; the cheeks broadly and thickly covered with similarly 

 coloured hair, the hair on the lower part of the front soot- 

 coloured, on the rest of the body (including the abdominal 

 fringes) black ; wings fuscous-violaceous. ^ . 



Length 37 mm. 



Java. Ardjuno. (Scheepmaker leg.). 



Front, except above, strongly, closely, deeply punctured ; 

 the vertex with deep, widely separated jiunctures, irregularly 

 arranged, and sparser on the sides above the ocelli. Mesono- 

 tum strongly and closely punctured, except in the centre 

 where they are sparser, the sparsely punctured central part 

 being separated from the more closely jiunctured surrounding- 

 space by a smooth space. The scutellum is much more closely, 

 but not so strongly, punctured ; the post-scutellum is closely
