TO NEW GUINEA IN 1904 ann 1905. PART I. 217 
Clypeus large, its apex broadly projecting, the sides ending 
in distinct teeth ; the centre rounded, almost transverse. Ocelli 
in a curve; the hinder separated from each other by a 
distinetly greater distance than they are from the eyes. The 
3rd abscissæ of the radius and cubitus are longer, but not 
much, than the 294; the 1° recurrent nervure is received 
shortly beyond the middle; the 274 near the apex of the basal 
fifth of the cellule. 
This is a Thynnus as limited by Ashmead in his classifi- 
cation of the family, »Canadian Entomologist«, 1903, p. 98. 
Scoliidæ. 
Discolia nitida Smith. 
Described from Aru (Journ. Linn. Soc. III, 152; c.f. also 
Saussure, Cat. Gen. Sp. Scol., 108). The specimens in the 
collection do not agree in all respects with Smith’s description; 
they are smaller; but fit it fairly well on the whole. The body 
and legs are densely covered with long black pubescence. The 
space outside the hinder ocelli is strongly, but not closely 
punctured, the punctures irregularly arranged; there is a 
distinct furrow on the lower half of the front, bordered irre- 
gularly by deep punctures; the apex of the clypeus is depressed, 
opaque and closely rugosely punctured. There are scattered 
punctures along the base and sides of the mesonotum ; the 
basal half of the scutellum and the post-scutellum are more 
weakly and closely punctured, this being also the case, but 
more weakly, with the metanotum; the pleuræ are more 
strongly and closely punctured. Basal segment ofthe abdomen 
weakly and sparsely, the middle slightly more strongly, the 
apical coarsely, rugosely punctured and with the hair dense 
and long; it is equally long an the basal segment, but not 
so dense; the middle segments are almost bare and are very 
shining. The underside of the flagellum is dark rufo-fuscous.
