This genus, which is rather closely related to the preceding, occurs only in the 

 mountain districts of Southern California and the Pacific coast of Mexico. Three so- 

 called species are known. They may be separated thus : — 



Table for separating the Species of Chimarocephala. 



A. Front uniting with the vertex in an angle. The hind margin of the 



pronotum somewhat acute. Scutellum of the vertex gently declivous. 



b. Body ridged, wrinkled, or coarsely rugose. Tegmina and wings 



complete in both sexes [1. pacifica, Thorn.] 



bb. Body less strongly rugose. Tegmina and wings somewhat abbreviate 



in the female [2. behrensi, Sauss.] 



AA. Front roundly uniting with the vertex. The hind margin of the 

 pronotum somewhat obtuse-angled. Scutellum of the vertex decidedly 

 sloping 3. otomita, Sauss.

Hab. Noeth America, Los Angeles, California (D. W. Coquillett). 



While there are no records of this species from south of the international boundary- 

 line between the United States and Mexico, it certainly occurs to within a few miles of 

 the frontier and will eventually be taken in Southern California. Colour- variations, 

 similar to those found in the members of the preceding genus, are also characteristic of 

 this and the next species.]
