another long hyaline space on the apical portion of the posterior margin ; veins 
blackish ; 'pterostigma elongate, broadly dilated at the apex ; free posterior cellule 
broadly rounded ; •posterior wings with a similar band to that in the anterior, but 
much paler, greyish. Length of body 1-li'" ; expanse of fore-wmgs 4"'. 
Sometimes common amongst undergrowth in woods, but apparently- 
uncertain in its appearance. 
Coquebert's figure gives a very faint idea of the insect, and the 
neuration is incorrectly delineated, but Latreille's description suits 
Avell. Curtis's figure is very characteristic, but the colouring rather 
too dark. 
Genus Peeipsocus, Hagen (18G6). 
Fsocus, p. auctorum. 
Tarsi 2-jointed. Pterostigraa free. Discoidal cell incomplete, 
open. Only two complete cellules on the apical portion of the posterior 
margin ; the last being altogether absent.
