SOME NEW HOMOPTERA FROM THE SOUTH AND 

 SOUTHWEST. 



BY ELMER P. BALL. 



In working over material for the Biologia the author has been 

 constantly handicapped by our lack of knowledge of the forms 

 occurring in the extreme South and Southwest. Through the 

 activity of two exceptional collectors, Mrs. Annie Trumbull 

 Slosson, in Florida, and Prof. F. H. Snow, in Arizona, our 

 knowledge of the fauna of these regions is being greatly increased. 

 Some of the interesting material they have gathered has been 

 worked out and is described below. 



QBcleus snowi sp. nov. 



Form much as in linmtus but slightly larger, lighter colored and with a 

 shorter vertex. Resembling fulvidorsum but much larger and with a nar 

 rower vertex. Length, 7.5 mm. 



Vertex very narrow, as in lineatus but shorter, extending scarcely its 

 own width in front of the eyes, nearly parallel throughout ; front narrow 

 above, regularly widened to the antennae and then narrowing more slowly 

 on to the clypeus, a faint median carina. In profile the front is very 

 slightly convex to the middle of the eye, above which it bends back to a 

 slightly obtuse angle with the vertex. Pronotum broadly and shallowly 

 emarginate behind, scarcely longer in the middle than the width of the 

 vertex. Scutellum large with three distinct carinae and two others faintly 

 indicated. Elytra very broad, a distinct slightly reflexed margin outside 

 the costal nervure at the base. 



Color bright straw color, eyes darker, ocelli rufous, scutellum testaceous, 

 carinae pale. Elytra subhyaline, veins closely beset with setigerous black 

 dots. Stigma small, smoky, with setigerous punctures on inner margin.
