64 NOTES ON JAMAICAN HEMIPTERA 



Described from one pair taken at Mandeville. This is a 

 little white insect with much the aspect of a diminutive white 

 Phlepsius. 



Xestocephalus Balli n. sp. 



Aspect of a small Eitiettix seminuda. White, tinged with fulvous on 

 the vertex, pronotum and scutellum. Front suffused with ferruginous and 

 sending two slightly divergent lines of the same tint over the apex of the 

 head to about the middle of the vertex where they are deflected and end in 

 two brown dashes, anterior edge with a black point close to each eye. An- 

 terior border of the pronotum with a few brown marks and a black point 

 behind each eye, disk with an angulated transverse pale brownish vitta pro- 

 duced anteriorly on the middle and deflected laterally almost to the posterior 

 angles, disk posteriorly with a vague median cloud. Scutellum a little 

 darker toward the base. Elytra white, becoming a little smoky toward its 

 apex; marked before the middle with a strong oblique angulated fuscous 

 vitta widened into a large square blotch on the middle of the claval commis- 

 sure; behind this on the costa is a small dot at the middle, a larger one on 

 the node and another at the first apical nervure; inner margin with a short 

 oblique fuscous vitta just beyond the apex of the clavus, and the transverse 

 nervures beyond the middle are touched here and there with brown. Legs 

 white; the tibiae and tarsi spotted with fuscous. Length 3*4 mm. 



Described from one female example taken at Mandeville 

 April 3d. 



Platymetopius loricatus Van Duzee. 



Seven examples of a species that I place here with some 

 misgivings were taken by me at Kingston, Mandeville and 

 Montego Bay. Some of these have the face entirely pale yel- 

 low, while in others it is quite evenly covered with obscure 

 irrorations, sometimes almost indiscernable, but wherever there 

 is any darker color on the face the pale angulated mark on the 

 base of the front is visible. The females have the last ventral 

 segment about as long as the two preceding united and quite 

 strongly, almost angularly, produced at the middle. The valve 

 of the male is short and broad and rounded behind and the 

 plates are short and arcuated, forming a border to the valve,, 

 with a small acute apical prolongation. 



Prof. Ball has kindly sent me for examination an insect 

 from the Island of Trinidad that I believe belongs to this 

 species. 



Platymetopius nasutus n. sp. 



Form and general appearance of loricatus. Vertex strongly produced, 

 its length about twice its width between the eyes at base, surface flat and 

 horizontal. Front a little wider toward the apex than in loricatus, the
