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, 

 grey, thickly spotted and clouded with fuscous, but with a very distinct curved 

 median pale space under the "forked" vein ; 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 greenish-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 greenish-ochreous, the penultimate segment fuscescent ; there is a fuscous 

 spiracular line on each side, a dorsal fuscous line, and obsolete fuscous lines on each 

 side of it].

N.B. — The genus Myopsocus (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 Elipsocus does with regard to Ccecilius. The de- 

 scribed species are M. lugens, Hagen (N. America), unduosus, Hagen 

 (Ceylon), griseipennis, McLachl. (Australia), suidfraternus, McLachl. 

 (Assam). Hagen indicates a species from Fiji, and I have one from 

 New Zealand. All are remarkable (and M. Eatoni is no exception) 

 for the coloration, which approaches that of Psocus variegatus. Mr. 

 Eaton's discovery of a European Myopsocus is of the greatest interest.
