and Coahuila, lioth in Riverside County, California, and in an 

 air-line but a relatively few miles distant from one another. 



Biological Notes. — In the San Jacinto Mountains this species 

 was found in an area of Upper Sonoran spiny chaparral, at an 

 elevation of between 6500 and 7500 feet, on the south facing 

 slope of a hog-back ridge southeast of Strawberry Valley, a 

 location where the valley itself and surrounding slopes were 

 covered with Transition pine forests. The area in which it was 

 found has been correctly mapped by HalP" and Grinnell and 

 Swarth,'! in studying respectively the plants and vertebrates of 

 the range. The species was not at all abundant and the material 

 taken was secured onty by persistent search, in situations where 

 beating was impossible and sweeping difficult. The species ap- 

 parently persists well into the month of September, as the pres- 

 ence of one immature female would indicate. 



Morphological Notes. — The only noteworthy variational feat- 

 ures which are evident from the series are in the female sex. 

 The caudal margin of the pronotal disk varies from the type 

 described to one in which the margin is almost straight transverse. 

 The frontal costa in the same sex may show no widening between 

 the antennal bases, or it may have the marked dorsal expansion 

 continuous and evident as far ventrad as the median ocellus. 

 This latter condition occurs in the single Coahuila female. In 

 the male sex there is a very faint indication of a similar varia- 

 tion, but it is not as evident as in the female sex. The number 

 of teeth on the ventro-external margin of the ovipositor jaws 

 varies to as many as six, occasionally differing in the paired jaws. 



Remarks. — This interesting genus and species is very similar 

 to Morsea in habitat and actions, and the two were taken at the 

 same locality (Coahuila), although it is quite probable in dif- 

 ferent situations. Our information is, however, so limited we 

 can formulate no warranted generalizations regarding the insect.
