almost exactly the aspect of a narrow Aphrophorid but the po- 

 sition of the ocelli on the edge of the vertex close to the eye 

 will distinguish it. It may readily be recognized by its very 

 black color. 



297. Spangbergiella vulnerata Uhler. 



Crescent City, Sanford, St. Petersburg and Ft. Myers. 

 These specimens, males and females, agree exactly with those 

 taken by me in Jamaica and differ from Signoret's figure in 

 having the scarlet lines on the pronotum converge nearly to a 

 point at the anterior margin, not at all in line with those on 

 the vertex. 



298. Parabolocratus flavidus Signoret. 



Taken at most of the. places where I collected but not at all 

 common. This species is very close to viridis but the vertex is 

 more pointed; the pygofers of the male are longer and narrow 

 to a point at the apex; the last ventral segment of the female 

 is produced in a short obtuse median tooth, and the venation is 

 a little different as described by Signoret. The type specimens 

 must have been faded as the color of the living insect scarcely 

 differs from that of viridis. 



Tribe Deltocephalini. 



299. Platymetopius Ioricatus VanDuzee. 



Sevenoaks, St. Petersburg and Ft. Myers. Occasional. 

 The dark color and pale yellow front will distinguish this from 

 the others here enumerated. 



300. Platymetopius obscurus Osborn? 



Not uncommon at most places where I collected. These 

 individuals have the vertex longer than those from Canada in 

 my collection and they may represent a distinct species. 



301. Platymetopius cinereus Osborn & Ball. 



Taken occasionally at all stations. The small size and pale 

 grey color will distinguish this species. 



Two other species of Platymetopius were taken by me which 

 I have not been able to determine to my satisfaction.
