52 P. CAMERON. HYMENOPTERA I. 



This species is very similar to D. albicollis, Christ., the two may be separated thus : 

 The second radial cellule much longer than its width at the apex; the wings 

 dark fuscous violaceous; the hair on the abdomen black; the calcaria and tarsal 



spines black albicollis. 



The second radial cellule at the apex not much shorter than its length along 

 the costa ; the wings almost hyaline, the hair on the abdomen white ; the calcaria 



and tarsal spines pale fulvous de-Meijerei n. sp. 



Length 16 mm. 



The occiput and collar thickly covered with long white hair; the hair on the vertex 

 tinged with fulvous. There is a double row of large deep punctures in a curve in front of 

 the ocelli and a single one behind them ; the part below the front row is smooth; the rest 

 of the front is coarsely punctured. The hinder part of the vertex bears large, widely separated 

 punctures. Mesonotum closely, distinctly punctured. The scutellum is similarly, but less strongly 

 punctured, with a smooth band down the centre and on the apex; the post-scutellum less 

 strongly, but slightly more closely punctured, with the apex smooth. Base of metanotum 

 closely and rather strongly punctured and covered with white pubescence; the apical slope 

 smooth, covered with a pale fulvous pile. Abdomen at the base sparsely, at the apex strongly 

 and closely punctured; the base of the first segment covered with white hair; the apices of 

 the segments fringed with white hair except the penultimate which, at the apex, is thickly 

 covered with dark brown pubescence. The pubescence on the last segment is black. The 

 wings hâve a steel-coloured iridescence, the base and front hâve a fulvous tinge, the stigma 

 and nervures are black. The apex of the 2 n <l radial cellule does not project so much beyond 

 the cubital as it does in E. albicollis, the cubital cellule, too, being narrower. 



2. Dielis manokwariensis sp. nov. 

 Manokwari, May. 



Black, the occiput, prothorax and base of mesothorax thickly covered with long white 

 hair; the apices of the abdominal segments broadly and the tibiae and tarsi covered with 

 bright fulvous hair; wings fuscous violaceous, the base lighter in tint, slightly tinged with 

 fulvous; the radial cellule wide; the apex about one half shorter than the length along the 

 costa; the apical abscissa of the radius straight, oblique, but not so long, nor so sharply 

 obliquely sloped as in albicollis. Ç. 



Length 17 mm. 



Front and vertex smooth, the lower part of the front and the inner orbits above nar- 

 rowly, punctured. Upper part of the clypeus smooth, the lower irregularly striated. The sides 

 and apex of mesonotum strongly, but not very closely, the base more sparsely and slightly 

 more weakly, punctured ; the middle smooth. Scutellum smooth, the apex with 2 rows of 

 punctures, the basai row with fewer punctures than the apical. Base of metanotum smooth ; 

 the apical half on the sides sparsely punctured and haired. Abdomen almost smooth; the 

 apical segment covered with stiff black, mixed with dark rufous, pile. The hair and spines 

 on the tibiae and tarsi fulvous; the apical spines rufous ; the calcaria black. 



The abdomen is shilling, probably when fresh it would hâve micaceous tints; the stiff
