in both sexes. The tegmina are oval, and have a large 

 dark central patch, the middle of the central carina being 

 but little elevated ; the principal vein of the costal area in 

 the wings of both sexes is furcate near the base ; the trans- 

 verse, veins in this part are rather wide apart, and black. 

 The wings of the male are of full size, but those of the fe- 

 male are scarcely longer than the mesothorax. The abdo- 

 men of the male is cylindrical, with the seventh and eighth 

 segments rather swollen ; the terminal ventral segment does 

 not extend beyond the eighth dorsal, and is not swollen 

 and more membranous than usual ; the last dorsal segment 

 is small, and arched at its extremity, with the anal styles 

 short, cylindrical, obtuse, and setose ; the abdomen of the 

 female is longer and more robust, the sixth ventral segment 

 with a short spine in the middle of its posterior margin ; 

 and the oviduct is membranous, and does not extend be- 

 yond the middle of the eighth dorsal segment.

This obscurely-coloured, very slender species is well 

 distinguished by the very short legs, annular antennae, and 

 granulated anterior part of the body. The head is small, 

 oblong, convex ; eyes very globose and prominent ; between 

 them in the male is a circular depression, within which the 

 ocelli are placed; the two posterior ones on raised pale- 

 coloured tubercles, giving the appearance of a pair of greatly 

 enlarged ocelli. In the female the ocelli are small and less 

 conspicuous. The antennae are slender, about 50-jointed, 

 brown, with the majority of the joints pale at the base ; the 

 terminal joints are very indistinct, and close to the tip is a 

 rather broad white ring. The pro- and mesothorax are finely 

 but rather distantly granulose. The tegmina are small, oval, 

 with the veins strongly marked, and with a moderately ele- 



vated tubercle a little before the middle of the chief vein. 

 The wings are rather long and narrow, equally developed 

 in both sexes, stained pale brown, with the veins rather 

 darker ; the costal area pale luteo-greyish, varied with 

 darker purplish-brown clouds ; the principal veins marked 

 alternately with short black streaks ; median vein furcate 

 at about one-fourth from the base of the wing. Legs, 

 especially the four hind ones, very short, slender, and 

 simple. Abdomen very long and slender, the terminal seg- 

 ments in the male not dilated above, and scarcely so beneath, 

 widely gaping at the tip ; anal styles small, and buff. The 

 terminal ventral segments, in the only female I have seen, 

 may possibly have been injured, — the plate analogous to the 

 oviduct being flattened, and only extending to the extremity 

 of the seventh dorsal segment, and notched at its tip, fol- 

 lowed by two pairs of lateral compressed plates, narrow, 

 and pointed at the tip, and another bifid flattened plate 

 with the two anal styles. 



Obs. One of the specimens of the male, received with the 

 rest from Mr. Bates, is destitute of ocelli (fig. 2d).

I am indebted to Mr. Curtis for allowing our friend, 

 A. H. Haliday, Esq., to make me a sketch of this very 

 distinct species, which is unique in his collection. It is re- 

 markable for the very short mesothorax, which is not 

 nearly so long as the prothorax.
