17,4 Crawford: The Psyllidas of Borneo 359 
Female genital segment short, both valves acutely pointed. 
Borneo, Sandakan {Baker), 1 female. 
Arytaina variabilis Crawford. 
Probably this is a widely distributed species, as it has been 
found in the Philipines, Malay Peninsula, and now in Borneo, 
all by C. F. Baker. The dark band on the hind margin of the 
forewing makes this an easily recognized species. 
Psylla fumosa Crawford. 
Six more specimens of this species have been collected by 
Baker at Sandakan, Borneo, all closely resembling the type, 
and bearing the same similarity to the Philippine species, P. 
crenata.
