208 [February, 



Hag., MS.], $ , dried. Thorax above, luteo-fuscous ; abdomen discoloured, the seg- 

 ments darker posteriorly, the venter paler than the dorsum. Wings transparent, 

 the marginal area of the fore-wing slightly discoloured, and containing about seven 

 simple cross-veinlets before, and eleven beyond, the nodal point : neuration piceous, 

 nearly every cross-veinlet marked with a roundish blackened spot. Legs dull pale 

 brownish-yellow, each with the femur twice banded with piceous, the distal ex- 

 tremity of the tibia black, and the tarsus sub-lutescent [" with darker tip to the 

 tarsus," Grundl., MS.]. Setae white, or greyish-white, with black annulations and 

 joinings ; the annulations towards the base of the seta? at every joint, then at every 

 alternate joint, and, still further from the base, at every third joint. Long, corp., 

 5' — 7'5 ; al., 7*5 — 8" ; seta? circiter, 10 mm. 



Sab. : Rangel Mountains, Cuba, in June (Poey, Chas. "Wright: 



and Grimdlach ; Hag. Mus.). There is no £ im. in the collection, butt 



only a sub-imago with seven cross veinlets in the marginal area of the 



fore-wing before the nodal point ; but there are four g im. of, perhaps, 



another species which have none there, and only nine in the pterostig- 



matic space. Their thorax seems to be piceous, and their wings are 



spotless. 



Teloganodes, n. g. 



Allied to Ephemerella, having the anal nervure of the fore-wing 

 similarly approximated to the 1st axillary nervure towards the wing- 

 roots {vide Trans. Ent. Soc. Lond., 1871, pi. ii, 5), but differing, as 

 follows : — Hind-wing obovate-oblong, sub-similar in outline to that of 

 Sabrophlebia {vide op. cit., pi. v, 2), but more obtuse: neuration ex- 

 tremely simple, comprising three longitudinal nervures, viz. : a strong 

 sub-costa terminating near the extremity of the costal projection, 

 followed by a forked and a simple nervure comparable with the 2nd 

 and 3rd nervures in the hind-wing of Bcetis pumilus (op. cit., pi. v, 

 25«). Two caudal setae. Type, T. tristis, (in Cloe), Hag. Distrib., 



Ceylon. 



Leptohtphes, n. g. 



Allied to Tricorythus, but differing as follows: — Caudal setae, 2. 

 "Wings with more numerous cross-veinlets in the disc (none in the 

 marginal area), and having the recurrent membrane produced (as in 

 Oligoneuria, &c.) into a short, free, subulate prolongation at the peak 

 of the mesonotum ; the terminal and inner margins, perhaps, fringeless. 



Leptohyphes cximius, n. sp. 

 Adult $ dried. Body discoloured, pitch-black. Wings transparent, talcose 

 or slightly dimned with very pale sepia-greyish ; neuration pitch-brown. Fore- 

 legs greyish-black ; hinder femora greyish-black, hinder tibiae and tarsi greyish-white. 

 Seta? dull whitish. Long. corp. (shrunken), 1 ; al., 8, setae circiter, 8 mm.
