longation of the head before the eyes is certainly of generic value at 

 least. 



Mesovelia mulsanti White 1879. 



Trans. Ent. Soc. London, vol. 17, ser. 3, p. 268. 



"General color yellowish testaceous to green. The gibbous hind lobe 

 of the prothorax lead color, marked with a yellow stripe along the middle; 

 the outer sides and tip of the scutellum, the veins and cuneus of the 

 wing-covers, the eyes, the tylus, the apical joint, points of articulation, 

 base, a few marks in the antennje, a large part of the end of the tarsi, and 

 the tip of the tibiae, are brown. The underside of body clothed with a 

 close silvery pile. 



"Antennse are slender, filiform, longer than the abdomen, the basal 

 joint is barely a little thicker than the others, of about the same length 

 as the third and fourth, the second joint much shorter than the others, 

 and the antenniferous tubercles are expanded in front so as to give a 

 trumpet-like enlargement to the front of the craijium. From the slightly 

 bent clypeus the slender rostrum extends back to the middle coxae, the 

 second joint being long and tapering. The prothorax is contracted into 

 a short, transverse front lobe, but widened at the shoulders, which are 

 tubercle-like and prominent, and the posterior margin is cut almost 

 square off; behind this the scutellum is conspicuous, and has a triangular, 

 callous elevation on the disc and a smaller one behind it." — Uhler. 



Distribution: Massachusetts, New York, New Jersey, Maryland, North 

 Carolina, Florida, Ohio, Illinois, Kansas and Texas. 



The specimens that have come under the writer's observation conform 

 in a number of other points not mentioned above. The head is large 

 before the eyes and bears four black shiny setiferous tubercles, two on 

 either side of the median line, some distance in front of, and on a line 

 with, the inner margins of the compound eyes. A similar pair lie in the 

 back part of the head laterad of the ocelli and on a line with the pos- 

 terior margin of the eyes. These are found on both sexes, apterous and 

 winged, and upon the nymphs. The adults also have a median longi- 

 tudinal groove extending from the clypeo-frontal suture to the caudal 

 margin of the head. 



The female abdomen is much wider than that of the male and in 

 profile very different (see pi. XIV). 



Champion states that Uhler's bug checks with White's description, 

 and since there is still some question regarding the species, the original 

 description is here appended "in toto."
