smooth. Thorax smooth. Fore-wings rather narrow, lanceolate. I<^euration : 12 

 Teine ; 7 and 8 stalked out of 6, 7 to costa. Hind-wings not broader than the fore- 

 wings, eTenly tapering from a broad base to an acute apex, cilia about as broad as 

 the wing. Neuration : 8 veins ; 6 and 7 stalked ; 3 from before angle of cell, but 

 almost connate with 4 ; 5 somewhat bent over towards base. Ahdomen slightly 

 flattened ; ^ genital segments conspicuous. Legs : hind tibise hairy. 



This genua is allied to Sj/mmoca, Hb., but differs in the neuration 

 of the fore-wings. 



2223 (1). Apatema mediopallibum, sp. n. 



Antennce Tery pale ochreous, delicately annulated with brownish fuscous. 

 Palpi recurred to above the vertex, apical joint two-thirds the length of the 

 second ; second joint pale ochreous, barred at the base and before the apex with 

 fuscous externally ; terminal joint pale ochreous, clouded with fuscous nearly to the 

 apex externally. Head nnAface shining cinereous. Thorax pale cinereous, shaded 

 with greyish fuscous. Fore-wings very pale ochreous, much mottled and shaded with 

 fuscous, leaving an ill-defined pale central band and a small costal spot running through 

 the apical cilia (this is visible on the under-side) ; no dark spots are clearly defined, 

 but the fuscous scales are somewhat concentrated on the cell at one-third from the 

 base, and again about the end of the cell where a dark spot appears to be redupli- 

 cated, or dilated, downward and outward towards the outer extremity of the fold ; 

 cilia pale greyish fuscous, with an ill-defined pale ochreous line along their base, not 

 reaching above the apex ; on the under-side a pale spot is visible in the costal cilia, 

 Exp. al., 12 mm. Hind-wings (1), pointed, apex slightly depressed ; shining pale 

 grey ; cilia pale brownish. Abdomen shining, pale cinereous. Hind legs pale 

 cinereous.

An inconspicuous species reminding one very much of Oecogenia

JBERTKAUIA PRISCA, Kolbe, A GENUS AND SPECIES OF PSOCID^ 

 NEW TO BRITAIN. 



BY ROBERT McLACHLAN, F.R.8., &c. 



In July last Mr. C. A. Briggs, so successful in his quest after 

 Psocidce, sent me an example of a somewhat large apterous species 

 just found by him on a mossy boulder in the vicinity of Lynmouth. 

 At that time I could not examine it closely, so suggested to Mr. 

 Briggs that it looked much like Bertkauia prisca, and that he should 

 obtain more. He has done so, and I find my suggestion as to name 

 quite justified, and Mr. Morton tells me he also has verified the 

 insects with Kolbe's descriptiou. The bibliography is as follows : —
