Vol. VI] VAN DUZEE— SPECIES OF ORTHOTYLUS 123 



bowing ; cuneus long and narrow, scarcely attaining the tip of 

 the abdomen in the female, surpassing it in the male. Rostrum 

 short, reaching on to the intermediate coxae. 



Dextral hook of the male genitalia broad on its basal half, 

 the ventral margin abruptly produced and incurved at the apex 

 which nearly attains the sinistral margin of the segment ; sinis- 

 tral hook slender and incurved. 



Color pale green; sides of the venter and pectus more or 

 less infuscated or black, almost entirely fuscous in the male. 

 Head greenish or reddish-brown ; the basal fovae and two ap- 

 proximate spots on the base of the front fuscous, the latter 

 sometimes forming vittae; clypeus pale anteriorly. Pronotum 

 dark reddish fuscous, becoming black laterally and behind the 

 callosities or entirely black in the male; median line some- 

 times enlarged so as to cover the disk posteriorly ; lateral edges 

 and the surface anterior to the callosities pale or whitish in 

 the female. Scutellum black, the basal lobe sometimes with a 

 red spot on either side, the disk of the apical lobe pale. Elytra 

 pale or tinged with reddish, the clavus infuscated, at least 

 apically ; apical half of the corium irregularly fuscous, omitting 

 the slender costal and apical margins ; cuneus whitish, fuscous 

 at apex in the male. Membrane infuscated, the disk of the are- 

 oles nearly black, with a darker ray beyond them. Antennae 

 rufo-testaceous, infuscated at apex, the basal joint brown or 

 black. Legs pale; hind femora infuscated on the apical two- 

 thirds ; tips of the tarsi black. 



Described from three females and one male taken at Hone- 

 oye Falls, New York, in June and July, 1915, by Mr. M. D. 

 Leonard and kindly sent to me for study by Mr. H. H. Knight. 

 The large size and maculated membrane will distinguish this 

 species. It has somewhat the aspect of Lopidea cuneata 

 Van D. or of a Plagiognathus, but the free connivent arolia 

 and other characters show it to be a true Orthotylus.
