March, 1919.] DaVIS : CiCADAS OF THE GeNUS CiCADA. 78 



seven male examples taken in Mission Valley on the hillside oppo- 

 site the city of San Diego, July 9, 1913. This species makes an un- 

 usually loud crackling noise which is often repeated and well sus- 

 tained, but the insect was very active and difficult to capture, espe- 

 cially as its home was among the cactus on the steepest part of the 

 hill." 



Mr. Van Duzee has been good enough to send me one of the 

 above mentioned males, in addition to which I have, through the kind- 

 ness of Prof. Myron H. Swenk, been able to examine two additional 

 males from the collection of the University of Nebraska. One is 

 labeled San Jose del Cabo, " Lower California, Mexico, Eisen Coll., 

 1893," and the other simply " Lower Calif. ? " 



Cacama maura (Distant). 



18S1. Proarna maura Distant, Biol. Centr.-Am., Honiop., i, p. 13, pi. 2, fig. 5. 



The original description states of the fore wings that the " basal 

 area, costal membrane, and transverse veins at bases of second and 

 third apical areas black." Basal area of the wings also black. It is 

 said to inhabit Mexico, also Yucatan. 



In the collection of the U. S. National Museum there are several 

 specimens from Yucatan labeled maura, which are brownish instead 

 of black. There is also a chestnut-brown female in the writer's col- 

 lection from Yucatan, supposed to belong to this species, and which 

 is figured on the accompanying plate. 



Cacama longirostris (Distant). 



1881. Proana longirostris Distant, Biol. Centr.-Am., Homop., i, p. 13, pi. 

 2, fig. 4, 4a and 4b. 



In the original description is the statement that the tegmina have 

 a " black basal area," but a smaller one than in maura. Fig. 4 b, re- 

 ferred to above, shows the rostrum extending beyond the opercula 

 to the " apex of the first abdominal segment." 



Uhler, in Entomologica Americana, Vol. IV, p. 84, 1888, says of 

 longirostris: " Inhabits Mexico. It resembles the preceding species 

 [maura] in form, but has a much longer rostrum, and lacks the broad 

 tract at the base of the wings."
