ORTHEZIA CATAPHRACTA. 235 



Long, 35 mm. 



Male " grey- white, wings diaphanous, at the base 

 narrow, then immediately widening on the lower side, 

 the whole contour being a long broad oval ; close to 

 the nearly straight anterior margin is a strong raised 

 nerve, which ends at about the middle of the length ; 

 from this, at a little distance from the base, furcates a 

 slight nerve directed towards the inner margin, but 

 not reaching it, and becoming evanescent at about the 

 same distance from the base as the strong costal nerve. 

 The antennas slender, filiform, about one-third shorter 

 than the wing, the articulation obscured. Head, 

 thorax, and abdomen also obscured by a white mealy 

 powder; from the end of the abdomen projects a 

 divergent pencil of about twelve white hairs, which is 

 fully as long as the whole insect. The legs are also 

 covered with the same kind of mealy powder, and 

 there is a trace of it on the wings. Length, exclusive 

 of tail, \ line ; expanse of wrings, If lines " (Douglas, 

 ' Trans. Exit. Soc. Loiid./ 1. c., p. 302). 



Habitat. Chiefly among moss, about the bases of 

 the stems of various grasses, Carex, heather, or among 

 dead leaves and debris beneath moss. Often in com- 

 pany with Newsteadia (Orthezia) floccosa. Abundant 

 on hedge-banks in shady spots, and on mountains and 

 moors. It has been recorded from several localities 

 in Scotland. In June, 1902, I found the species 

 plentiful in suitable spots on many of the main islands 

 in the Western Hebrides, including St. Kilda; and 

 Mr. J. Macnaught Campbell, of the Kelvingrove 

 Museum, has sent the species to me from Dalmilling- 

 ton, Ayrshire. Douglas (' Ent. Mo. Mag.,' 1. c.) gives 

 Ireland, but does not refer to any particular locality. 

 Mr. Brockton Tomlin informs me that it is extremely 

 common in co. Antrim, and has during the last three 

 years sent examples to me from that district. It has 

 been taken in some numbers at Bolton-le-Moors, 

 Lancashire, by Mr. C. E. Stott ; and I have found it 

 common in many parts of Flintshire, Denbighshire,
