rings ; tibiae finely spotted with black, and with a broad apical black ring ; tarsi 
having the 1st joint pale, the 2nd and 3rd blackish. Anterior-wings semi-opaque, 
gi’ey, thickly spotted and clouded with fuscous, but with a very distinct curved 
median pale space under the “forked” vein j the costal margin and all the neuration 
closely spotted with deep black ; pterostigma triangular, not darker, but with a faint 
yellowish (or greenish) tinge ; extreme apex slightly reddish. Posterior-wings 
greyish -hyaline, with darker neuration, and a darker greyish clouding along the 
inner margin. Expanse, about 8 mm. 
[Notes on the recently-killed insect, made by Mr. Eaton, prove that the body- 
colours are much changed : according to these notes, the head is greenisli-ochreous 
(with the black spots and lines above noticed) ; the ground colour of the antennae 
pale greenish-grey. Eyes dark greenish-grey, freckled with black. Thorax above 
greenish-grey, freckled with black ; sides for the most part black. Abdomen above 
dull greenisli-ochreous, the penultimate segment fuscescent ; thei*e is a fuscous 
spiracular lino on each side, a dorsal fuscous line, and obsolete fuscous lines on each 
side of it].

N.B. — The genus Mgopsocus (Hagen, 1865) is new for the 
European Fauna. It has the neural characters of Psocus , but has 
3-jointed tarsi, and thus stands in the same relative position with 
regard to Psocus as Plipsocus does with regard to Ccccilius. The de- 
scribed species are M. lugens , Hagen (N. America), unduosus, Hagen 
(Ceylon), griseipennis, McLachl. (Australia), and fraternus, McLachl. 
(Assam). Hagen indicates a species from Fiji, and I have one from 
New Zealand. All are remarkable (and M. Patoni is no exception) 
for the coloration, which approaches that of Psocus variegatus. Mr. 
Eaton’s discovery of a European Mgopsocus is of the greatest interest.
