It is readily separated from a c u t u s by the smaller size, darker 

 color, and strong contrast of bright yellow front against the dark 

 border of face. I collected it last summer at nearly every point 

 where collections were made — Hamburg, Eagle Bridge, Nassau, 

 Salem, Cold Spring Harbor, Jamaica and Staten Island and at all 

 places it seemed more plentiful than a c u t u s . It must 

 have been very rare to have escaped Dr Fitch's attention during 

 his Vv^ork a half century ago. 



Platymetopius obscurus Osborn 

 Ohio Nat. S: 274 

 Taken at Gold Spring Harbor August 1904. 



Platymetopius angustatus n. sp. 



Slender; light olivaceous green, length of female 4 mm. 



Vertex acutely pointed nearly twice as long as width between 

 eyes. Front very narrow, tapering to clypeus, long, slender, 

 twice as long as wide, apex rounded, lorae, elongate nearly reaching 

 margin of genae, pronotum strongly arched in front a little more 

 than half as long as vertex, posterior margin slightly sinuate. 

 Scutellum large, median impression deep, strongly curved, elytra 

 truncate at apex, costal cells hyaline. , 



Color. Light greenish olivaceous somewhat tinged with cup- 

 reus; vertex with dusky lines somewhat diverging toward apex 

 and front light yellowish green, more greenish at apex where there 

 are three angular lines extending to border of the front; ocelli 

 yellow, eyes black, pronotum greenish mottled with dusky, elytra 

 greenish coppery with round hyaline spots in anteapical and apical 

 cells; dorsum of abdomen black, margins yellow; costal cells 

 hyaline, margined with black, beneath yellowish green, legs pale, 

 base of spines and the tarsal claws dusky. 



Genitalia. Last ventral segment of female rounded behind, 

 pygofers reaching tip of ovipositor. What appears to be the 

 male of this species collected at the same time and from the same 

 trees differs from the above described in that the vertex is shorter, 

 less acute, about 1-3- times as long as width between the eyes, the 

 angular lines on front somewhat less conspicuous. The color 

 more inclined to yellowish. The pronotum, scutellum and ch^tra 

 somewhat more coppery, the genitalia having the valve large, 

 convex, posterior border angulate, plates triangular, short, about 

 ^ length of pygofers. Length 3.75 mm. Described from one 

 female and five male specimens beaten from pinetrees, Oyster 

 Bay, Aug. 18, 1904.
