COLEOCENTIUJS. (EDEMATOPSIS. 49 



Wings deep brownish flavous, with the nervures piceous ; areolet 

 sessile and entire ; nervellus intercepting recurrent nervure of 

 lower wing at its junction with the median. 



Length 33 millim. 



SIKKIM; TE^ASSEBIM. 



Type. Location unknown. 



I am not quite satisfied that my friend Col. Bingham placed this 

 female in its correct genus ; he says that the terebra is " emitted 

 from the apical segment, which with the next three segments, 

 looked at from the ventral side, are ensheathed one within the 

 other " ; but this does not prove that its base is covered by the 

 hypopygium ; and his description of the " transversely plicated 

 and rugose" mesonotum, with the figure of the sessile areolet and 

 position of the nervellus, point rather to its inclusion in Nhyssa. 

 Cameron (Zeits. Hym. Dipt. 1903, p. 302) is of the same opinion. 



This species is probably widely distributed.

GENOTYPE, Tryplion scabriculus, Grav. 



Head subglobose ; eyes small, entire, shortly and sparsely 

 pilose ; frons convex, mandibles bidentate, with the lower tooth 

 the shorter ; clypeus large and stout, apically broadly rounded or 

 subtruncate ; that of d 1 nearly flat, as long as the face and not 

 broader than long, discrete, with the basal fovea on either side 

 and apically subreflexed ; clypeus of $ semicircularly discreted 

 basally, very strongly convex and produced, with a fine transverse 

 carina, intercepted by a conspicuous central subglobose tubercle, 

 extending across its centre. Antennae slender, filiform and a little 

 shorter than the body. Thorax stout and subovate, with distinct 

 notauli ; metathorax apically attenuate and produced above the 

 hind coxse ; upper and petiolar arese present ; spiracles circular 

 and situated between the centre and base. Scutellum deplanate 

 and apically obtuse ; its basal fovea multistriate. Abdomen sub- 

 petiolate, with the second and third segments often punctate- 

 rugose ; that of J sublinear, with all the segments longer than 

 broad, the last apically attenuate; that of $ linear-subfusiform, 

 with the three basal segments elongate and the remainder tele- 

 scoped, apical ventral segment covering base of terebra, which is 

 straight and not quite half the length of the abdomen. Legs 

 slender, with the tarsal claws simple. Wings of normal breadth, 

 with no areolet. 



Range. Europe, Assam.
