LEAFHOPPERS OF MAINE. IO9 



Xestocephalits pulicaritis Van Duzee. 



Xestocephalus pulicar'ms Van Duzee. Buf. Soc. Nat. Sci. Bui. 5, 1894, 



p. 215. 



A small dark brown species with light yellowish spots on prothorax 

 and elytra. Length 2.5 mm. 



This is somewhat infrequently taken but seems to occur pretty com- 

 monly in places where Carex grows and it is evidently fairly common 

 on the food plant given by Van Duzee. Carex vulpinoidea. 



Taken at Orono in the Orono bog, Aug. 29, at North Harpswell Aug. 

 13, Houlton Aug. 24th, Cherryfield Sept. Sth, 1913. 



Xestocephalus fulvocapitatus Van Duzee. 



Xestocephalus fulvocapitatus Van Duzee. Buf. Soc. Nat. Hist. Bull. V. 



25, 1894. 



Differs from puUcarius in being slightly larger the head fulvous and 

 unmarked, the pronotum and elytra are brown faintly marked with 

 lighter spots. Length 3 mm. 



This species was separated from puUcarius by Van Duzee on the larger 

 size and fulvous color of head an-d he says "in company with the preced- 

 ing (puUcarius) of which it may prove to be a variety." It appears to be 

 closely related and often found associated but material in hand will 

 hardly warrant combining the two species as this form appears to main- 

 tain a fairly constant difference in different localities. 



Specimens for Maine have been taken in company with puUcarius in 

 the Bangor bog near Orono from Carex Aug. 31st. 



Xestocephalus nigrifrons n sp. 



Size and general structure of fulvocapitatus but mostly jet black, lower 

 part of face including most of frons, black. Length female 3 mm. 



'Head rounded, nearly as wide as pronotum, ocelli near together and 

 close to the front margin of the vertex ; face tumid, polished, sutures 

 obscure; pronotum rounded in front sloping to sides slightly excavated 

 posteriorly. 



Color black with a few white points, vertex black at base, brownish 

 near apex, ocelli white with black central dot, face brown above, two 

 transverse wavy 'lines on margin next vertex, rest of face polished black, 

 pronotum and scutellum black, the latter with four white points, two 

 at base and one each on hind border opposite the suture, elytral picture 

 like fulvocapitatus but basal part black, two white dots on clavus, several 

 on basal half, apical part semitransparent with smoky patch on apex. 

 Beneath black, legs light brown. 



Genitalia: Female ventral segment similar to fulvocapitatus but 

 more distinctly notched at middle. 



One specimen Orono, Maine, Aug. 10, 1913. This may possibly be a 

 black variety of fulvocapitatus but it is widely different from any speci-
