HYMBNOPTEROUS FAMILY. STEPHANID^E. 821 



normal, Neek finely trans-striate, semiannular smooth in front, 

 basally arcuate striate ; mesonotum rugose ; scutellum laterally 

 strongly punctate ; metanotum longitudinally carinate. Pro- 

 pleurae smooth ; mesopleuras finely trans-striate, apically punctate; 

 metapleurse and median segment cribrate punctate, the latter 

 with an elongate triangular cential basal punctate and very 

 finely trans-striate and dull space, bounded by large punctures. 

 Petiole trans-striate, shorter than the remaining smooth 

 segments. Terebra shorter than body, spicula pale red, sheaths 

 black. Hind coxae finely trans-striate, their femora glabrous, 

 bidentate ; tibiae compressed to middle. 



Black ; head red, apices of frontal tubercles and the carina on 

 the vertex black ; two basal antennal joints rufo-testaceous, 

 third darker red, apically black. Anterior tibiae and all tarsi 

 rufescent ; femoral teeth white. Wings hyaline. 



Length 13 mm. ; abdomen 7| mm. ; petiole 3| mm. ; terebra 

 11 mm. 



Habitat : Luang Prabang, Indo-China. H. V. de Salvaza ; 

 29. ix. 1917. Type in the British Museum. 



The sculpture of the median segment resembles that of 

 D. leacodonhts Schlett., which the author describes as " basally 

 and centrally smooth," and agrees also in the colour of the head 

 and of the femoral teeth. It differs in sculptvire of head and 

 prothorax and black terebral sheaths.

$ . Frons and occiput arcuately rugose, latter with slight 

 longitudinal sulcus; posterior margin of head bordered. Second 

 and third flagellar joints of equal length, and about one-third 

 longer than first. Neck elongate, glabrous, centrally deeply im- 

 pressed and laterally vallately elevated ; semiannular smooth, 

 with a few apical transcarinse, and a band of indistinct punctures 

 before the base, Mesonotum rather densely punctate ; meso- 

 pleurae subglabrous, with a few superficial punctvires ; median 

 segment with large, rather dense, but not confluent punc- 

 tures. Petiole rather longer than rest of abdomen, trans- 

 striate ; second segment basally constricted and slightly rugu- 

 lose, remaining segments smooth. Terebra slightly shorter 

 than body, sheaths entirely black. Hind cox^e trans-striate, 

 hind femora alutaceous, shining, bidentate; hind tibiae com- 

 pressed to middle. 



Black : face below antennae, inner orbits partly, outer orbits 

 entirely pale stramineous ; mandibles and anterior legs bright 

 ferruginous ; hind legs with coxae, base of femora and apex of 

 tibiae more or less black. In the type-specimen the basal half
