{Fig. K.) are rather shorter than in the male, (Curtis, pi. 194, fig. 1.) and 

 slightly thickened to the tips. Eijes small, lateral. Ocelli three in a 

 triangle. 



Neck short, apparent. Collar in both sexes bilobed behind, narrower 

 than the head, the remainder of the thorax as broad as the head. Scu- 

 telliim rounded. Postscutelhim? longitudinally divided in the centre.* 

 Wings of equal length in both sexes, pubescent and ciliated. Superior 

 with a nervure running from the base, parallel to the costa, nearly half 

 way, whence it is continued along the costal margin a short distance, and 

 then becomes furcate, one of the furcations descending a little way into 

 the disc of the wing, at an angle pointing towards its tip, the other furca- 

 tion continued (gradually diminishing in strength) along the costal margin 

 to the tip. Inferior, narrow and nerveless. Legs slender, the anterior 

 and posterior thighs in the males incrassated (Curtis, pi. 194, fig. 8, 

 a fore leg of the $ .) Anterior thighs in the female gradually incrassated 

 to the tips, where there is a strong indentation in the inside, (Tab. 

 II. L. a.), posterior thighs not so thick as in the males; the posterior 

 pair of legs appear very far behind, especially in the males, from the great 

 length of the posterior coxse. 



^6c^omen of the male sessile, obconic, depressed, polished (except the 

 last segment), the first segment large, arched above, covering one or two 

 segments? longitudinally divided down the centre by a deep groove and 

 having a notch at the hinder margin in the centre (Fig. R.//and g) . The 

 male organs of generation slightly protruded (Fig, R. d). That of the 

 female requires a more minute examination. It is long, angulated in pro- 

 file beneath (Fig. N.), attenuated from about half its length to the tip, and 

 composed of seven polished joints, the third and fourth of which are the 

 broadest, the previous joints being narrowed to the base; the first joint is 

 arched above, with a slight notch at its hinder margin in the centre ; the 

 four following are depressed in the centre, the lateral margins being 

 raised; the two l?ist joints are the narrowest,' and at the tip of the last the 



* The general formation of the thorax of the male is similar to that of the 

 female. My figures were taken from specimens which had not been injured by 

 being pinned. From the incorrectness of Mr. Curtis's drawing of a portion of 

 the thorax of the male, I should conceive that his specimens had been [con-- 

 fiderably injured,
