THE BRITISH NATURALIST. [November 



de Y. Kane records it "from Sligo'' ({7t litt.J. So far as I can learn 

 this species is most restricted in its habitat, except on the chalk in the 

 south eastern counties, and far from being a common species, except 

 in its favoured haunts, is much more local than other supposed rarer 

 ones. Under the name of O. obscurus, Dr. Jordan records it from 

 Scandinavia, " Entomologist's Monthly Magazine," Vol. VI., p. 122. 

 The late Professor Zeller records it (Entomologist's Monthly Mag- 

 azine," Vol. VI., pp. 50-54) from near Meseritz in Posen, in dry, 

 sandy places, on the 19th June and nth July (1869), under the name 

 of obscurus. Drs. Standinger and Wocke give the "whole of Europe 

 except the polar region; Hyrcania (North Persia) and Asia Minor" 

 as its limit in the Palaearctic region (" Catalog," p. 343). 



Trichoptilus, Wlsm. 



It has long been recognised that pallidum did not belong to the 

 genus Aciptilia, Hb., and in 1869, 1^^- Jordan wrote: — Paludiim 

 certainly does not belong to Aciptiliis, the much longer palpi and the 

 slightly thickened tibiae would be quite enough to distinguish it. 

 ("Entomologist's Monthly Magazine," Vol. VI., p. 150;, and with 

 regard to the same subject, Dr. Jordan wrote to me: — "With regard 

 to pallidum, it is clear that this species with ononides, siceliota and 

 baptodachtyla form a little group by themselves. Zeller, in a letter to 

 me, allowed that these might be separated" {in litt.}, and since Mr. 

 Mayrick has recently separated it with siceliota, Zell. from all our 

 "plumes" and included them under the Tri choptolis oi Walsinghsim, 

 I have followed the new departure. The genus is thus diagnosed: — 

 "Face without tuft, rounded; ocelli obsolete; tongue developed. 

 Antennae two-thirds, in ^ ciliated (i-f). Labial palpi moderate, 

 ascending, second joint with short projecting scales beneath, tending 

 to form a short angular apical tuft, terminal joint short or long, 

 filiform, tolerably pointed. Maxillary palpi obsolete. Tibiae thick- 

 ened with scales on origin of spurs, outer spurs nearly equal inner. 

 Forewings bifid, cleft from before middle; vein 2 out of 4 or absent, 

 3 absent, 5 and 6 extremely short, 7 absent, 9 absent, 10 from near 8 

 or absent, 11 from near 8, long. Hind wings trifid, third segment 

 with more or less developed tooth of black scales in dorsal cilia, often 

 slight; vein 2 from middle of cell, 3 absent, 5 and 6 very short, 7 to 

 apex." (" Trans. Ent. Soc. Lond.," 1890, p. 484). Of this genus
