and Hamburg, N. Y., June 14, 1902. Like dorsalis, it is a 

 willow feeder. 



25. Orthotylus serus, new species 



Closely related to marginatus Uhler, differing in having a 

 pale median vitta from front of pronotum to tip of scutel- 

 lum, the inner limit of the pale costal vitta straight, and in 

 the form of the male claspers. Length 6 mm. 



Vertex distinctly flattened before the obtuse basal carina, this flattening in 

 marginatus very feeble; clypeus little prominent with feeble impression at 

 its base; eyes, viewed from the side, reaching well toward the gula, in 

 marginatus distinctly smaller. Pronotum as in marginatus, its length three- 

 fifths its basal width; the callosities connected by an elevated area anteriorly 

 which is scarcely apparent in marginatus; the posterior lobe nearly smooth, 

 distinctly shagreened in marginatus. Rostrum attaining the hind coxae, in 

 marginatus not surpassing the intermediate. Dextral male clasper forming 

 two squarish denticulate lobes, the ventral produced for about twice its width, 

 with a truncate apex, its upper angle subacutely prominent; basal lobe 

 squarish, broader than long and oblique at apex; sinistral clasper triangu- 

 larly enlarged at tip with its apex obliquely truncate and its upper angle sub- 

 acute ; no basal appendage discernable. 



Color, black and yellowish testaceous; above black, lateral and posterior 

 margins of the vertex, broad median vitta from front edge of pronotum to 

 tip of scutellum, and broad costal vitta on the elytra pale, the latter with a 

 straight inner margin and enclosing toward its apex an obscure smoky cloud; 

 cuneus fulvo-testaceous with a large fuscous cloud against its inner margin; 

 membrane deep smoky with dark nervures and a pale spot at apex of cuneus, 

 sometimes much reduced. Whole upper surface clothed with long pale de- 

 cumbent hairs. Beneath black with a broad pale vitta, extended along the 

 sternum to tip of venter in female; genital pieces largely pale; legs dusky 

 testaceous with the tarsi embrowned; rostrum pale, black at tip; antennae black. 



Described from three male and ten female examples taken 

 by me as follows: Hamburg, N. Y., July 1, 1911; Go- 

 wanda, N. Y., August 2, 1907; Colden, N. Y., July 7, 1901 ; 

 Salamanca, N. Y., July 24, 1911. It lives on thorn bushes 

 (Crataegus, species). 



Holotype, male, and allotype, female, in collection of the 

 author; paratypes in his collection and in that of the Cali- 

 fornia Academy of Sciences. 



Type locality, Hamburg, N. Y. 



Genus Strophopoda, new genus 



Aspect of a small Plagiognathus, but with an obtuse fa- 

 cial angle; allied to Chlamydatus with a narrower head and 

 a distinct suture at base of tylus.
