Vol. VI] VAN DUZEE— SPECIES OF ORTHOTYLUS 103 



of Colorado. It is not impossible that the green elytral points 

 may bear stiff dark hairs in fresh individuals. 



Type, female, in collection of the author. Paratype, fe- 

 male, in Museum of California Academy of Sciences (No. 

 310). 



12. Orthotylus viridis, new species. 



Form of dorsalis but with the head and pronotum of for- 

 mosus; pale green, with the head, anterior lobe of the prono- 

 tum and legs yellowish. Length 5mm. 



Head as in formosus, a little oblique. Vertex slightly flat- 

 tened, the basal carina straight and acute, not tumid and gently 

 arcuated as in formosus. Front moderately convex. Clypeus 

 small, prominent. Rostrum attaining the apex of the inter- 

 mediate coxae. Pronotum shaped as in formosus, with its sides 

 feebly concavely arcuated and the humeri rounded; callosities 

 large, but little prominent. Elytra nearly parallel, a little wider 

 than in uniformis. Upper surface clothed with a minute pale 

 pubescence. 



Dextral hook of the male genitalia broad at base, tapering 

 along its upper edge to an incurved subacute point, which 

 nearly attains the opposite wall of the segment ; sinistral slen- 

 der, acute, surpassing the sinistral notch. 



Color a nearly uniform green, usually quite strongly tinged 

 with fulvous-yellow on the head, anterior lobe of the pronotum 

 and scutellum, legs and venter, the costa often paler or whitish. 

 Antennae quite strongly infuscated, especially on the basal and 

 apical joints. Apex of the tarsi blackish. Membrane whitish- 

 hyaline, very slightly enfumed, the nervures pale green. 



Described from two males and six females taken by Mr. 

 H. H. Knight at Batavia, N. Y., July 5 and August 2, 1914, 

 and one female taken by Mrs. Annie Trumbull Slosson at Lake 

 Toxaway, N, C. This insect is most closely related to for- 

 mosus and serves to connect that species with dorsalis and its 

 allies on the one hand and uniformis and related forms on the 

 other.
