366 Mr. W. F. Kirby on a 



cross-nervure on the fore wings, and rises considerably 

 beyond it on the hind wings. 



It is quite possible that Mr. Dolby-Tyler's insect may 

 be distinct from M. vulgipes, Gal v., but I do not like to 

 separate them until the allied forms are better known. 



Two specimens. 



Uracis quadra (?). 

 Libellula quadra, Earab. Ins. N<5vr. p. 31, pi. ii. fig. be (1842). 



( ? , no. 12.) "Apices of eyes green, balance cinereous, 

 together with the epicranium, clypeus, and labrum, the last- 

 mentioned somewhat olivaceous. 



" Dorsal aspect of mesepisterna black, with rugose flaves- 

 cent markings transversely. Not u in grey. Tergum of 

 abdomen deep fuscous, with somewhat flavous markings. 



" Tips of wings fuliginous." 



Nine specimens in the collection, belonging to both sexes. 

 They agree fairly well with Rambur's figure and description 

 of U. quadra, except that the triangle of the hind wings is 

 followed by only two rows of cells increasing, not three, as in 

 Rambur's figure. It may be noted that the true U. quadra, 

 Ramb., is the type of his genus Uracis ; not imbuta, Burin., 

 which is a perfectly distinct species, with a pruinose blue 

 male. The species which I here call U. quadra may be 

 known by the upper surface of the thorax being finely and 

 transversely striated with brown and black. 



Lepthemis vesiculosa. 

 Libellula vesiculosa, Fabr. Syst. Ent. p. 421. n. 7 (1775). 



( $ , no. 11.) "Eyes green, rufescent at apices, remainder 

 greyish. Vertex, ocelli-bearing sclerite, epicranium, clypeus, 

 and labrum verdant green. 



" Dorsal aspect of mesepisterna, notum, and abdominal 

 tergites 1-3 verdant green ; tergites 4-7 green with black 

 apices, 8-10 black. Cercopoda green. 



" Pterostigma green." 



One male specimen. 



Mesoihemis verbenala. (PI. XV. fig. 2.) 

 Lepthemis verbenata, Hagen, Neur. N. Aroer. p. 162 (1861). 



(No. 5.) " Apex of eye rufescent, remaining portion grey 

 with a greenish tinge. Epicranium, clypeus, and labrum 

 olivaceous. 



" Dorsal aspect of mesepisterna, notum, and abdominal 

 tergites 1-3 dull green, 3 to last olivaceous, with fulvous
