SOME NEW SPECIES OF DELPHACIl).^^: * 



BY C. S. SPOONER, GEORGIA STATE BOARD OF ENTOMOLOGY. 



The following species were, with one exception, taken by the author 

 during the past five years. In the genus Pissonotus they form a very 

 considerable addition to the list of our species. 



]\Iy thanks are due to Professor A. D, MacGillivray of the University 

 of Illinois for going over the manuscript and for valuable help and sugges- 

 tions. I also wish to thank Professor J. Chester Bradley of Cornell 

 University for the loan and exchange of specimens and Mr. C. P. Alexander 

 also of Cornell University, for the gift of specimens of several desirable 

 species. 



The author has planned an extensive study of the Delphacidse and 

 would be grateful for the loan or exchange of material. He will gladly 

 name specimens for the privilege of retaining desirable duplicates. 



Pissojiotus guitatus, n. sp. 



Brachypterous $ . — Eyes oval, deeply indented below to receive the 

 antennae, colour grey ; vertex considerably^)nger than wide, slightly 

 rounded in front, projecting slightly before the eyes ; carina of the vertex 

 all present, rather indistinct; vertex uniformly black except the caudo- 

 lateral angles which are slightly yellowish. Carin^e meeting on the front 

 just below the curve of the vertex, extending distinctly from this point 

 throughout the length of the front, indistinct on the vertex ; front consid. 

 erably constricted between the eyes, deep pitchy black above, becoming 

 gradually lighter until it is white at the base ; clypeo-frontal suture curved, 

 the clypeus deep uniform black with the median carina distinct ; the black 

 colour of the clypeus extends as a band across the anterior cox?e as is 

 characteristic of the genus. 



The second segment of the antennae about one-fourth as long again as 

 the first, with a few protuberances ; antenna uniform pale honey-yellow. 



The length of the prothorax from the anterior to the caudal margins 

 about e(|ual to that of the vertex; caudal margin slightly concave, carinae 

 distinct ; anterior portion deep, shiny black ; narrow band on posterior 

 margin dirty white.
