MONOPHADNUS. 27 



as the clypeus, which projects a little over it ; the labrum and clypeus are white ; man- 

 dibles blackish, as are also the palpi. The transverse radial nervure is received in the 

 apical fourth of the cellule, the first recurrent beyond the middle of the second cubital 

 cellule, which is only a little longer than the first, and not half the length of the 

 third; second recurrent received a little beyond the second transverse cubital; the 

 transverse median is received a little in front of the middle of the cellule. In the hind 

 wings the transverse nervures are at the edge of the wing. There is a bulla in the 

 transverse radial and first transverse cubital. The apex of the coxae, the trochanters, 

 the apex of the femora, the tarsi except at the apex, four anterior tibiae, and the base 

 of the posterior tibia? are black. The metatarsus is longer than all the other joints ; 

 the claws almost bifid. The cubital nervure forms almost a half-circle ; the hinder 

 wings are lighter-coloured than the anterior. 



Comes near to ~M. longipennis, Norton, but probably distinct.

The clypeus is truncated at the apex, rounded at the sides ; the lateral frontal foveee 

 are shallow, much smaller than the central, which is joined by a wide suture to the 

 frontal area, which is deep, rounded behind the ocellus and hollowed in front of it. 

 Frontal sutures wide, moderately deep ; the vertex is indistinctly carinated in the 

 centre; below the lateral ocelli is a small fovea. Spurs very short, curved; claws 

 apparently simple. Wings longish ; the first cubital cellule is small, broader than long, 

 the second about one third shorter than the third ; the transverse radial nervure is 

 received in front of the apical third of the cellule, first recurrent in the basal third ; 

 second not far from the second transverse cubital : there are spurious veins running 

 through all the bullae. The male does not differ from the female beyond the second 

 cubital cellule being a little longer compared with the third. 



This species cannot, I think, be M. cordigera ; for that is stated to have the antennae 

 " about as long as the head and mesothorax together," while in the present species 

 they are distinctly longer than the head and entire thorax together ; the abdomen in 

 M. cordigera is " almost as broad as long ;" here it is much longer than broad ; in M. cor- 

 digera the wings are clearer at the.apex ; here they are uniform in tint, and the claws are 

 simple. Compared with M. suturalis the antennae are longer and thinner, more pilose, 

 and the third joint is not nearly so long compared with the fourth; the sides of the 

 clypeus are more rounded, the central frontal foveae larger and deeper, and the lateral
