Ncocladia gen. nov. 



Head transverse, menisciform, inflexed, bearing coarse shal- 

 low punctures, the space between the eyes wide, the ocelli in a 

 triangle much widest at base, the posterior ones being rather 

 near to the eye-margins, only about half as far from these as 

 from the anterior ocellus. Maxillary palpi long, 4-jointed, the 

 first and third sub-equal, the second much longer than either 

 of these, the fourth curved and very elongate, much longer than 

 the second, and clothed with long hairs. Mandibles broad and 

 apparently simply pointed in one aspect, but in others seem to 

 have three microscopic teeth at apex. Antennae in front view 

 of head inserted well below the middle ; those of the female sim- 

 ple, the scape long and slender, the pedicel rather shorter than 

 the first of the six funicle joints, which when seen at their widest, 

 gradually decrease in length and increase in width to the sixth, 

 which is transverse, the club oval rather longer than the two 

 preceding joints ; the scrobes short and rather indefinite. Pro- 

 notum widely rounded in front ; mesonotum about as long as 

 the axillae (which meet inwardly) and the scutellum, the latter 

 much deflexed apically. Wings with a pattern in the female 

 (but uniformly clear in the male) the stigmal vein long, the mar- 

 ginal very short, the post marginal longish in the female, and 

 rather longer still in the male. Middle tibiae armed at the apex 

 with denticles as also are the inner margins of the tarsi ; pos- 

 terior femora on the lower side, the posterior tibiae and basal 

 joint of tarsi on the upper side foliaceously ciliated, the tibiae 

 with two distinct spurs. Abdomen small and generally distort- 

 ed after drying, the ovipositor when exserted short and recurv- 

 ed like that of a Pipuncnlus fly. The male dififers chiefly in its 

 clear wings, much less dilated hind legs and the six long branch- 

 es of the antennae, which are inserted higher up on the head.

Ncocladia howardi sp. nov. 



Black with various metallic reflections, the antennae with the 

 scape ferruginous, the rest more or less obscure, becoming black 

 or dark fuscous towards the tip, as are the branches in the male. 

 Front and middle legs more or less yellowish-brown in the fe- 

 male, the middle tibiae darker, the base of their tarsi being pale, 

 the tips blackish. Posterior legs dark, the apex of- the femora 

 white. In the male the legs are darker, but both sexes varv
