fore-wings rather short and broad, the pterostigma is triangular, blackish in mature 
individuals, paler at the inner side ; in the ? the fore-wings are paler with darker 
clouds, and the veins margined with darker, the inner side of the pterostigma often 
conspicuously yellowish ; veins fuscous, that closing the discoidal cell, and the base 
of the superior apical furcation, pale ; the posterior wings paler than the anterior. 
Length of body 1^-2"' ; expanse of fore-wings 55-6"'.

AntenncB scarcely so long as the wings, very pilose in the <? , yellowish, the two 
basal joints and the apex fuscescent. Head yellow ; crown with a few fuscous 
markings about the conspicuously blackish ocelli ; nasus fuscous in its lower half, 
scarcely striped ; lahru.m darker ; pal/pi with blackish apical joint. Thorax yellow 
(sometimes fuscescent, or with fuscous markings). Abdomen yellow above, with a

hairy, and marked with very minute blackish dots. Wings hyaline ; anterior wings 
very thickly clouded and irrorated with greyish-fuscous ; with darker fuscous spots, 
especially about the pterostigma and posterior marginal cellules, and along some of 
the veins ; the radius about the inner side of the pterostigma conspicuously suffused 
with yellow, and some of the other veins also streaked with yellow. 
Length of body 1-1^'" ; expanse of fore-wings 4-4^'". 
Very common on tree trunks, but difficult to see on account of its 
coloration being so similar to that of the bark. In the Ent. Ann., 1861, 
this species was not separated from P.Jasciatus.
