This species may be distinguished from basalis by the piceous pronotitm 

 marked with whitish on the carinae, the shorter scutellum with its abrupt 

 white apex, and distinct carinae, and the more slender form of the insect 



6 PISSONOTUS APHIDIOIDES n. sp. 

 Van Duzee, Bui. Buf. Soc. Nat. Sci., V, p. 190, 1894. 



Broad oval, widest across the abdomen. Elytra reaching onto the second 

 abdominal segment, the nervures prominent. Color wood-brown inclined 

 to yellowish on the legs and disc of the tergum ; pleural pieces and sides of 

 the abdomen obscurely marked with piceous ; pronotum and usual transverse 

 band on the face, whitish ; the latter followed by a broad piceous band across 

 the base of the clypeus and anterior coxte. Cheeks marked with an oval 

 black spot below the antennae. Front with about three transverse pale 

 lines two of which are nearer the base, the other may be reduced to two 

 points adjoining the whitish apical band. Base of the scutellum irrorated 

 more or less with whitish, tibiae and tips of the tarsi brown. Elytra brown, 

 sub-opake, with paler nervures. [n one example the vertex is white with 

 the fovae and a dot on either side at apex black, and the base of the tergal 

 segments are brownish yellow. Length 3 to 3J^ m. m. 



New York. Described from two female examples, one taken at Sala- 

 manca, August 2nd, 1S89, the other at Colden a few days earlier. The latter 

 is a larger and darker specimen bearing a striking resemblance to some of 

 our brown plant lice. 



7 PISSONOTUS DORSALIS, n. sp. 

 Van Duzee, Bui. Buf. Soc. Nat. Sci., V, p. igo, 1894. 



Closely allied to the preceding. Dull yellowish brown, paler beneath ; 

 broad lateral margin of the tergum, some marks on the connexivum and 

 the base and apex of the pj^gofers in the female, piceous or blackish. Clypeus 

 deep black with some obscure spots opp isite the pleural pieces indicating a 

 transverse band; claws of the anterior and intermediate feet blackish, front 

 paling toward the base of the clypeus, immaculate above. Disc of the ter- 

 gum quite obviously tinged with yellow. In the male the front, vertex and 

 elytra have a reddish cast with the apical margins of the latter whitish, the 

 nervures concolorous. Aperture of the pygofers in the male broadest below 

 the middle, the stiles short and curved, their slender acute points approxi- 

 mated above, their base surrounded by the long curved ventral prolongation 

 of the outer superior angles of the pygofers. Length about 3 m. m. 



New York. Described from one pair captured in July, at Lancaster 

 and Colden. This species may be distinguished from the preceding by the 

 paler yellowish dorsum, and the brown, almost immaculate, front. 



8 PISSONOTUS BRUNNEUS, n. sp. 



Van Duzee, Bui. Buf. Soc. Nat. Sci., V, p. 190, 1S94. 

 Allied to P. aphidioides but much smaller. Color piceous brown tinged 

 with rufous on the front; breast soiled yellowish white, marked by the usual 

 broad piceous band which crosses the clypeus and curving backward on 

 either side covers the anterior and intermediate coxae and terminates in a 

 cloud on the post-pleura. Carinae paler than the adjacent surface, narrow
