This species was described by Uhler from a single female speci- 

 men from San Jose del Cabo, Lower California, and is now pre- 

 served in the collection of the California Academy of Sciences. 



The present description is drawn from a male speciiuen which 

 ]\Ir. \'an Duzee has coiupared with the type and pronounced iden- 

 tical. LHiler states in the original description : "rostrum reaching 

 over the posterior coxae." At the writer's request Mr. Van Duzee 

 sent the following notes on the type : "The rostriun scarcely passes 

 the apex of the intermediate coxae, it is flexed somewhat and the 

 best one can do is to estimate. LHiler might easily have thotight it 

 would pass over the base of the hind coxae, and it might altho I 

 would estimate it as just attaining the apex of the intermediate. The 

 callosites are outlined in piceous."
