THE JUMPING PLANT-LICE OR PSYLLID^ OF THE NEW WORLD. 59 



as in dugesii; size uniformly smaller; body and wings more slender; 

 vertex with sulcate depressions much less marked and conspicuous. 

 Female genitalia somewhat similar; male anal valve similar but 

 with apical portion much shorter and broader. 



Described from many males and females from Habana, Cuba 

 (Baker). 



Type in author's collection. 



Genus RHINOPSYLLA Riley. 

 Rhinopsylla Riley '83: 77.— Crawford '11a: 440; '1 lb: 483. 



Head often less deeply cleft in front than in preceding genera, 

 though sometimes very deeply cleft; anterior ocellus in front, as m 

 Freysuila; f rons covered by gense ; gense sometimes swollen (approach- 

 ing Euwayama of Triozinse). Antennae long. Thorax only slightly 

 arched. Legs long and slender; hind tibiae with a small spur at 

 base, or often none. Wings triozine, with no cubital petiole (M + Cu) 

 and no pterostigma, but resembling preceding genera somewhat also. 



Type of genus — Rhinopsylla schwarzii Kiley. 



This is a very interesting genus, in that it grades into Kuwayama 

 of the Triozinse on the one hand, and other species grade into the 

 preceding genera of Carsidarinae on the other hand. There are 

 unmistakable relationships to both subfamilies, but the most fun- 

 damental characters seem to indicate a closer relationship with the 

 Carsidarinae.
