2. — Stenopsocus nervosus, Stepheus. 
Fsocus nervosus, Steph. 111. p. 126, 36 (1836). 
AntenncB as long as the wings, yellow. Head yellow, brownish on the crown. 
Thorax shining chestnut-brown, the divisions of the lobes paler. Ahdomen yel- 
lowish. Legs pale testaceous. Wings hyaline, immaculate ; anterior wings with 
most of the nervures margined with very pale yellowish-hrovm ; pterostigma sub- 
triangular, broader and less elongate than in 8. immaculatus ; veins fine, brown. 
Length of body 1-1^'" ; expanse of fore-wings 4<-4:\"'. 
I know nothing of the habits of this species. 
In Stephens' collection it is represented by a single example, not 
in very good condition, which Hagen referred to S. immaculatus. I, on 
the contrary, thought it might be a large immature example of 8. cru- 
ciatus. However, in Mr. Dale's collection I find several examples 
which convince me that the species is good. The form of the pteros- 
tigma and the margined nervures readily separate it from immaculatus ; 
and the size, and length of the antennae, preclude the possibility of its 
being an immature form of cruciatus. The only other European species 
of this genus is P. stigmaticus (considered by Hagen to equal striatulus, 
Fab.) described by Imhoff and Labram in the " Insekten der Schweiz." 
I have not seen a type of that species ; according to the description, 
which is very short, it cannot be identical with nervosus, but more 
nearly approaches immaculatus.

Antenncn not so long as the wings, moderately thick, vaiying from yellowish to 
fuscous, according to the degree of maturity attained by the insect. Head shilling 
chestnut-brown ; the vertex on either side of the ocelli yellowish. Thorax chestnut- 
brown. Ahdomen yellowish or fuscescent. Legs pale yellow, the tarsi obscure. 
Wings hyaline ; anterior wings with four elongate fuscous spots near the base, two 
of which are placed on the posterior margin, and the other two above them (these 
spots vary greatly in intensity) ; the apical half of these wings is without spots, 
but there are pale greyish brown bands, one placed along the apical margin, and 
the others following the course of the veins ; pterostigma elongate, dilated in the 
middle ; veins brown ; the posterior wings have frequently two palo greyish-bruwn 
spots on the dorsal margin near the base. 
Length of body l-lj"' ; expanse of fore-vviugs 3-3^'". 
Very common on tree trunks, palings, &c.
