P. CAMERON. HYMENOPTERA. 24I 



pilose, except the face and metanotum ; the legs (especially the tibiae) more densely pilose than the 

 body. Mesonotum with the parapsidal furrows shallow, indicated at base only where the centre 

 of the notum is raised. 



Megalommum, Szép. 



1. Megalommum maculipenne sp. n. 



Black, the thorax, 4 front legs and the hinder coxae yellowish red ; the hinder trochanters 

 and the hinder femora, above of a darker red ; the rest of the hind femora, the hind tibiae 

 and their tarsi black; mandibles dark red, black at the apex; palpi pilose, pallid yellow; 

 basai segment of abdomen of a slightly deeper red than the thorax, its apical fourth black 

 in the centre, the base of the black part incised in the centre ; wings almost hyaline, an 

 irregular cloud in the basai half of ist cubital cellule, extending narrowly into the costal and 

 discoidal cellules; the Costa, stigma and basai nervures black, the radial, cubital and transverse 

 cubitals and the hinder part of the stigma pallid testaceous; the récurrent nervure thickened, 

 narrowed in front, the anal -nervure thickened at the base; the basai abscissa of the radius 

 is straight and oblique at the base and apex, the central part roundly curved. The ist abdo- 

 minal segment not quite twice longer than it is wide at the apex, the raised central part 

 gradually roundly narrowed from the base to the apex; the area on the 2°d longer than it is 

 wide at the base, bounded by distinct, smooth wide furrows, which do not unité at the apex, 

 being there separated by the projecting narrowed point of the area; there are no latéral 

 furrows; the suturiform articulation is distinct, smooth, roundly curved; the 31'd segment is 

 wider than long; it has a shallow oblique dépression on the sides. The ovipositor is as long 

 as the metanotum and abdomen. Pleurae, metanotum and legs densely covered with white 

 pubescence. There are 2 fine diverging keels down the centre of the face, the space enclosed 

 by them opaque ; the sides of the face irregularly transversely striated ; the upper striae more 

 widely separated and more curved than the others. The posterior discoidal cellule has the 

 basai nervure straight, the apical broadly rounded; both are bullated at the apex; the anterior 

 and posterior are roundly curved; the former is thicker than the latter, which, on the inner 

 side, is bordered on the basai three fourths by a narrow cloud, at the end of which the 

 nervure is bullated, where it turns up. There is a narrow fuscous cloud in the centre of the 

 hind wings in front. 



M. oculatum, Szép. has the hind legs coloured like the others and the ovipositor is 

 shorter than the abdomen. 



2. Megalommum fasciatipenne sp. n. 



Black, the thorax, base and sides of ist abdominal segment, the base of the 2 n <l more 

 narrowly and the legs reddish yellow; wings hyaline, the basai fourth of the radial cellule, 

 the cloud roundly narrowed, the ist cubital cellule, the anterior discoidal except for a semi- 

 circular hyaline spot in the centre of its apex, and a triangular one outside the récurrent 

 nervure, the narrowed end in front, and extending to the anal nervure, smoky; the nervures 

 black, the anterior and the stigma behind paler; the basai abscissa of cubitus broadly, roundly 

 curved ; the posterior cellule with the nervures curved except the basai transverse one. The
