the inner side they are almost parallel and extend below the top of 

 the clypeus ; the malar space is small. Apes of clypeus trans- 

 verse. Antennse slightly thickened beyond the middle, where 

 there is a large white ring. Areolet wide, the nervnres almost 

 parallel ; the second transverse cubital is faint ; the transverse 

 median nervure is placed considerably behind the transverse basal. 

 In the hind wings the transverse median nervure is broken near 

 the middle. Parapsidal furrows narrow. Median segment smooth 

 and bearing two transverse keels ; its spiracles small, oval. Fore 

 tibise narrowed at the base, shorter than the tarsi. Petiole rather 

 broad ; all the abdominal segments are banded with white ; the 

 last segment is entirely white. Ovipositor esserted. The last 

 segment longer than the preceding, its upper third projects over 

 the lower part. 



A genus easily known by the large wide head, very little 

 developed behind. The scutellum is roundly convex ; the meso- 

 pleural furrow is wide ; the oblique furrow on the metapleurse is 

 wide and crenulated ; the radial cellule is long and lanceolate at 

 the apex ; there is no nervule on the disco-cubital nerviu-e, nor on 

 the recurrent nervure ; the stigma is linear. 



EURYCBYPTUS LATICEPS, sp. nOV.

 gris. $ . 



Long. 10 ; terehra 5 mm. 



Antennse with the 9th to 15th joints white ; the tubercles white. 

 The face and clypeus, the inner orbits — the lower white part 

 obliquely narrowed, — the outer entirely, and the base of the 

 mandibles white. The face is sparsely punctured, on it are two 

 narrow furrows which end in the clypeal f ovese. Front and vertex 

 smooth and shining ; the lower ocelli are bordered by a furrow ; 

 there is an indistinct furrow down the middle of the front. 

 Thorax shining, bare ; a line on the pronotum, the apex of the 

 middle lobe of the pronotum, the scutellum, the median segment 

 behind the second transverse furrow, except for a conical black 

 mark in the centre of the apex, the tubercles, a pyriform mark 

 under the hind wings, and the greater part of the metapleurse — the 

 top and base are black — white. The mesopleural furrow is deep 

 and crenulated, except at the apex ; the base of the meta- and the 

 apex of the raesopleuras are foveated ; the metapleuras obscurely 

 punctured ; the apex is depressed, and has on the lower side four 

 short stout keels. The front legs are white, with the tarsi black ; 

 the middle coxse white, their trochanters black ; the hinder coxae 

 black, broadly white behind ; the trochanters are black ; the rest 

 of the four hinder legs are broken off. Wings clear hyaline ; the 

 nervures and stigma black. Abdomen black ; the apices of the 

 segments bordered with white, the last is entirely white ; the 2nd 

 and 3rd segments are closely and distinctly punctured; the 

 2nd segment at the base is raised, the raised part roundly narrowed 

 towards the apex and bordered by a shallow depression.
