toward the end, shorter than the third. Tongue scaled, as 

 long as the thorax beneath. 



C. ? gemmiferella* Labial palpi dark greenish-brown, 

 with a silvery stripe on the front of the third joint, and another 

 behind, continued to the second joint. Face, head and 

 thorax dark greenish-brown, with a narrow, central, silvery 

 line continued to the thorax, and one of the same hue above 

 the eyes on each side. Antennae dark greenish-brown, with 

 two silvery lines on the basal joint, the stalk annulated with 

 silvery, and a broad, silvery ring before the tip, which is 

 likewise silvery. Fore-wings dark greenish-brown to the 

 middle, and from the apical third to the tip, with an orange- 

 coloured patch rather beyond the middle of the wing, extended 

 across the wing, and a little produced along the costa behind, 

 having a large, transverse, oval, smooth patch of elevated 



* The following remark has already appeared in the 9th volume of "The 

 Entomologist's Weekly Intelligencer," p. 31: "Dr. Clemens has very liberally 

 forwarded me six specimens of his Cosmopteryx; but I find on close examina- 

 tion, that only four of them truly belong to Gemmiferella, the other two being 

 manifestly a distinct, though closely allied, species, which, though possessing 

 the three short longitudinal streaks near the base in place of the fascia, differs 

 in the following respects: The ground colour of the anterior wings is darker, 

 the orange fascia is paler, not so reddish, its margins are pale golden, instead 

 of silvery-violet and its hind margin is almost straight, and thus very different 

 from that in C. gemmiferella ; finally the apical streak is continuous, not inter- 

 rupted, and of a silvery-white throughout. I have much pleasure in naming 

 this species, after its captor, Cosmopteryx Clemensella." 



The exp. al. of Clemensella is 4J lines. H. T. S.
