stigmatus the elytra are proportionately broader, with the costa more 

 rouiulotl than in basal is. I have taken one male of coloepeum at Buffalo 

 and another at Sunset, Colorado, at an altitude of over 8,000 feet. 

 Cixias dorsalis ". ^i> 



Color blackish fuscous, paler beneath; front pleurrp and legs testa- 

 ceous brown, tingoti with ferruginous on the clypeus; front clouded 

 with brown, the carinir paler. Dorsal surface almost black with a 

 broad pale yellow vitta tinged with fulvous covering the whole vertex 

 the pro- and niesonotuni between the lateral carinae and the elytral 

 commissure^, where it becomes narrower and more obscured. Sides of 

 the mesonotuni deep l)lack. Costa very narrowly pale with a pale 

 spot on the base of the stigma; nervures concolorous, punctured, apical 

 areoles with a few vague paler spots. 



Vertex longer than in our other species, transverse, almost quad- 

 rangular, widened before by the expanded sides of the front. Pro- 

 notum very short, linear, roundly produced before, the anterior and 

 posterior margins almost parallel, very feebly angled behind; lateral 

 carime very oblique, terminating outside of the mesonotal carince, the 

 latter straight, but little divergent posteriorly; post-scutellum pale 

 across the middle. Pale commissural vitta of the elytra occupying 

 the interior claval areole. Wings smoky hyaline with fuscous nervures. 

 Length about 6 mm. 



Described from one female example taken by Mrs. Annie Trumbull 

 Slosson at Biscayne Bay, Florida. This species is very distinct from 

 any other known to me. Its black color with broad yellowish dorsal 

 vitta will at once distinguish it. 



The above six species of Cixius are all that are known to me to 

 inhabit North America, but Prof. Smith, in his Catalogue of the Insects 

 of Neiv Jersey, enumerates alhicincta Germ, from that State. I have 

 seen nothing that could be identified with that species, or have I 

 learned of its having been found elsewhere in this country. 



(ienus MYNDUS Stal. 



Myndus sordidipennis Stal. 



The species I have placed under this name is not uncommon about 

 moist springy spots in rich woods near Buffalo. All my specimens 

 differ from Stal's short and inadequate description in having the 

 abdomen more or less blackish fuscous. The elytra however agree 

 exactly and I believe my identification to be correct. 

 Myndus pictifrons St&l. 



This is another allied species with banded front, but it may be 

 readily separated from sordidipennis by the Ijrown vitta at the inner
