4 PIS50NOTUS BASALIS, n. sp. 



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



Macropterous form. Allied to marginatus but differs in having the 

 scutellum much larger, about as in Liburnia pellucida which this species 

 much resembles. It is however a much stouter insect than the latter and 

 the hind edge of the pronotum is straight. Front narrower than in P. mar- 

 ginatus, the median carina distinct. Color piceous black, hind edge of the 

 pronotum broadly white, extreme tip of the scutellum and narrow apex of 

 the front yellowish ; front, cheeks and vertex rufo-piceous, breast from the 

 apex of the anterior coxae to the base of the abdomen, and the coxai, femora, 

 and hind tibiae honey-yellow; tarsi whitish at base, the base of the tergutn 

 obscurely marked with paler. Elytra and wings whitish-hyaline, smoky at 

 base and slightly clouded at apex. Marginal nervure brown, the others 

 nearly concolorous. Antenna; soiled honey-yellow. Length 3^ m. m. 



Described from one female taken at Lancaster, N. Y., July 4th. 188S. 



A male from Columbus, Texas, in the National Museum collection 

 apparently belongs to this species. It differs from the female described 

 above in having the face piceous black with a white band across the apex of 

 the front and cheeks, three or four transverse marks and two marginal dots 

 on the basal half of the front, the narrow base of tne vertex and a broad 

 band on its apex including two dots, white. The base of the tergum is also 

 marked with yellowish. Pygofers much indexed below, the aperture 

 broadly ovate, the margins angularly produced inwardly on either side 

 above the middle, forming a blunt tooth. 



5 PISSONOTUS PALLIPES, n. sp. 

 Gillette & Baker, Hemip. of Colo., p. 69, 1S95. 



Allied to basalis but smaller and more slender. Head brownish ful- 

 vous; eyes, basal joint of the antennae and base of the clypeus piceous, the 

 latter polished. Pronotum piceous, the short median carina with a whitish 

 mark, the lateral with a slender pale line. Scutellum piceous-black, the 

 short abrupt tip whitish, the edges narrowly fulvous at base; carina? paler 

 in the female. Elytra whitish hyaline the marginal nervure and a cloud on 

 the shoulder brown, discal nervures faintly yellowish. Abdomen piceous 

 black, base of the vertex, edges of the genital pieces of the male and' the 

 margin of the plates in the female, paler or yellowish. Legs whitish, line- 

 ated with brown, tips of the claws brown. Breast whitish marked with a 

 broad piceous band which crosses the base of the coxie and clypeus. Geni- 

 tal segment of the male long, the aperture rather narrow, the sides produced 

 interiorly in a rounded lobe slightly incurved over the base of the small 

 stiles. Length about 3 m. m. 



California, Colorado. Described from one pair received from Prof. C. 

 I'. Gillette, taken among the mountains of North Western Colorado, and 

 two females taken near Los Angeles, California, by Mr. I). W. Coquillett. 

 These latter differ from Prof. Gillette's specimens in having the head darker 

 or almost piceous with a pale band adjoining the base of the clypeus, the 

 the vertex also wants the whitish marks.
