came from Chetopa, Kansas (D. R. Beardslee) and expand 120 

 millimeters. This is supposed to be not a great many miles from the 

 type locaHty. Cicada marginata has sometimes a line of pruinose 

 spots on the tergum, but generally these spots are inconspicuous or 

 have been entirely obliterated by age. In specimens of the same size 

 the eyes are much furthr apart in marginata than they are in the 

 allied Cicada dealbata described in this Journal for September, 191 5.

TWO NEW SPECIES OF ARRHENOPHAGUS WITH 



REMARKS. 



By a. a. Girault, 



Washington, D. C. 



The genotype of this genus heretofore has been supposed cosmo- 

 politan. It has been recorded from many parts of the earth, includ- 

 ing Asia and Australia. But in Australia there are two distinct spe- 

 cies, one described, which belong to Arrhcnophagoidca a genus which 

 differs from Arrhenophagus in bearing 5-jointed tarsi only. All other 

 specimens which I have seen from that region are the genotype of 

 this second genus. Ceylonese and Japanese specimens of Arrheno- 

 phagus represent the two species below but North American speci- 

 mens appear to be chionaspidis. The club is solid (in spite of all 

 statements to the contrary). 



I. Arrhenophagus albitibiae new species. 



Female. — Length 0.40 mm. 



Like the genotype but all tibia and tarsi are white, the antennse are yel- 

 lowish white. The venation is pale at tip, not ending in a small dusky spot. 



Described from four females on a slide in the U. S. N. M., labelled 

 "Arrhenophagus chionaspidis. 141 8. Fiorina saproscma Gvetn. From 

 male scales. Handy, Ceylon, Koebele."
