greyer ; on the posterior wings there is a distinct discal point (as in 

 the anterior), and the apical portion is distinctly clouded. Finally a 

 third, from Waitara, differs still more widely ; the posterior femora 

 are darker : the wings have scarcely a trace of the yellow colour so 

 striking in the type, but could be more correctly described as pale 

 grey ; the dark points in the anterior are much more numerous, and 

 are spread over nearly the whole wing, but the whitish spot at the end 

 of the upper cubitus is scarcely indicated, and is not margined with 

 black ; in the posterior the neuration is blackish in certain places, 

 causing a nebulous appearance. All three examples agree in size and 

 form, and at present it seems prudent to consider that from Waitara 

 as only a strongly marked variety, having in view the paucity of 



material.

TWO SPECIES OF FSOCIBM NEW TO BEITAIN. 



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



Herr H. Tetens, of Berlin, one of the most recent writers on 

 European Fsocidce, lately visited London, and through him I am able 

 to confirm the following species, of which I give brief descriptions, as 

 new to our List. 



Psocus MAJOR (Kolbe), Loens. 



Ps. sexpunctatus, L., var. major, Kolbe, Jahrb. d. Westf . Provinz. 

 Yer., 1879-80, p. 109. Ps. major, Loens, Stett. Zeit., li, p. 7 (1890) ; 

 Tetens, Ent. JSTachr., xvii, p. 375 (1891) ; Eeuter, Act. Penn., ix. No. 

 4, p. 25 (1893). 



Closely allied to Fs. 6-punctatws. Differs in the apex of the anterior wrings 

 being less rounded ; the pterostigma less dilated at the apex, and its basal portion 

 more or less opaque-whitish or yellowish ; the six subapical spots the same, but the 

 other markings of the wings are less evenly distributed, and in part congested into 

 an oblique fascia from the base of the pterostigma to the inner margin (somewhat 

 as in Ps.fasciatus), where it is widest, and the colour of the markings appears to me 

 to be brown rather than grey (minute differences in the neuration are also indicated, 

 and the colour of the body is said to differ in fresh individuals). 



I have one example in my British collection taken at Forest Hill, 

 near London, on September 30th, 1861. Mr. J. J. King does not 

 possess it amongst his extensive series of sexpionctatus from varied 

 British localities, and Herr Tetens {I. c, p. 376) was mistaken (of which 

 he is now convinced) in attributing (from description) Ps. suhfasciatus, 

 Steph., to this species. It is very possible I had more British examples 

 in view when writing my Monogr. of Brit. Psocidce (Ent. Mo. Mag.
