CONTRIBUTIONS TO HISTORY OF THE BRITISH PTEROPHORI. 35 



only superficially, for on comparison the dark brown digital 

 fascia and black cilia sufficiently establish its claim to rank 

 as a distinct species. I therefore propose for it the name 

 Tceniadactylus, and its place in our collections is between 

 P. Zetterstedtii and A. accmthodacti/lm. 



OxYPTILUS, Zell. 

 Lcetus, Zell. 



Imago. — Expause, 1) lines. Fore wing, ground colour whitish ochreous, 

 ruore or less clouded with pale brown. The costa is narrowly edged with 

 darker brown. The markings are few and inconspicuous. A black linear 

 spot on the disk of wing always distinct, and at the digital juncture — which 

 is nearly in the centre of the wing — are two small dark brown spots, and a 

 faint white dash indicative of a line ; and beyond this are two white lines 

 running through the digits and their fringes. Tips of both digits sharply 

 pointed, that of the inner deflexed. Fringes grey-brown, streaked with 

 black and white, except along the middle of the inner margin, where they 

 are whitish, with a small patch or two of black. Hind wings brown ; 

 fringes paler ; a small tuft of black scales on the third feather beyond the 

 middle, and a few white ones towards the base. Head and thorax colour 

 of fore wings. Abdominal junction much paler. 



The insect taken in Norfolk, and hitherto referred to this 

 species, should be labelled Distans, Zell., in our cabinets. I was 

 fortunate enough to meet with the true L(Btus in North Devon 

 during the last week in July, but only secured three specimens, 

 although I put into practice every expedient known to me as 

 usually successful in the capture of "plumes." 



I understand from Mr. Meek that he has seen specimens from 

 Kent, and, as far as I know, in that county and North Devon, are 

 the only known British localities for Lcetus, and at neither place 

 has Distans been seen. On the other hand, in Norfolk, at the 

 locality for Distans, Lcetus does not appear to occur. 



Oxyptilus distans, especially the continental type, is a broader- 

 looking insect, and in colour much darker than Lcetus. This darker 

 ground colour throws up the whitish markings (which are nearly 

 identical in form and position in both insects), consequently they 

 appear rather more distinct. Tiie black linear spot on the fore 

 wing of Lcetus shows up very distinctly. The smaller, more 

 compact black tuft on third feather of hind wing, in conjunction 

 with the marked difierence of ground colour, constitute, I submit,
