Vol. XI] VAN DUZEE—NEW HEMIPTEROUS INSECTS J29 



genital segment strongly subacutely produced, a little surpassing the valve; 

 sinistral notch deep, abrupt, dextral shallow, sinuate; sinistral clasper small, 

 forming a lobe at fundus of sinistral notch, dextral inconspicuous; plates long, 

 produced for more than twice their basal width, rounded at apex. In fasci- 

 atus the ventral genital segment is short, truncate, not nearly attaining apex 

 of valve; sinistral notch scarcely indicated, sinistral clasper long, acute at 

 apex and curved to conform with apical margin of valve; dextral clasper 

 ligulate, more than twice longer than wide, the plates short and subtriangular 

 in form, with their apex rounded. 



Color, castaneous-brown becoming paler on the head, pronotum and pro- 

 pleura and fuscous on antennae beyond basal segment: elytra fuscous with a 

 broad pale transverse band at apex of scutellum and a narrower one across 

 apex of corium, leaving the intermediate fuscous band a little wider than 

 basal pale band; cuneus and abdomen polished piceous black; membrane 

 deep fuscous with black veins, faintly marked with a paler spot at apex of 

 cuneus; in fasciatus there is a conspicuous pale band against apical margin of 

 cuneus. Legs castaneous. 



Female: Broader behind, as in fasciatus, the color paler anteriorly, some- 

 times with the corium almost entirely pale. In both sexes the upper surface 

 is closely minutely punctured and clothed with short appressed pale hairs. 



Described from 58 examples representing both sexes, taken 

 from pine trees at Berkeley, Calif., September 29 and Octo- 

 ber 14, 1919, by Mr. J. O. Martin, and two females taken 

 by me, one at Hoberg's Retreat, Lake Co., Calif., August 2, 

 1916, the other at Cayton, Shasta Co., Calif, July 15. 1918. 

 This species could easily be confused with fasciatus but the 

 thicker and darker antennae, dark legs, black cuneus, darker 

 membrane, narrower fuscous band on base of elytra, addi- 

 tional pale band at apex of corium and especially the very 

 distinct male genital characters will distinguish the present 

 species. 



Holotype, male, No. 782, and allotype, female, No. 783, 

 Mus. Calif. Acad. Sci.; and paratypes, all presented to the 

 Academy by Mr. Martin. 



Type locality, Berkeley, Calif. 



23. Orthotylus dodgei, new species 



Closely allied to pacificns Van D., separable by the blacker 

 membrane and very different male genitalia; black, sides and 

 abbreviated median vitta of pronotum, margins of elytra, 

 and legs, yellowish. Length 6 mm. 



Male: Head as in pacificus, the vertex flattened before the prominent basal 

 carina ; clypeus very prominent ; segment II of antennae rather longer than 

 from tip of scutellum to apex of head, three times length of I. Pronotum 

 as in pacificus, one-half wider than long; sides straight, carinate; surface 

 transversely rugose behind the prominent callosities. Apex of abdomen at- 

 taining middle of cuneus. Surface clothed with rather long scattering pale 

 hairs. Sinistral male clasper long, straight, somewhat clavate; dextral equally
