Two paratypic males and one paratypic female, as well as three males 

 from Raymond, Madera County, California, taken September 3, 1907, 

 have been examined by the authors. There appears to be little 

 variation in size and nothing noteworthy in structure, except that the 

 lateral foveolse are broader in some specimens than in the types and 

 in some more rectangular than elongate-trigonal. In color there is 

 considerable variation, a tendency toward linear streaking of the 

 dorsum of head, pronotum and tegmina being noticed in one Summit 

 House male, while two of the Raymond males are rather rufescent and 

 the remaining one is predominatingly buffy yellow, with the pattern 

 strikingly contrasted, the occipital bars and maculations of the anal 

 area of the tegmina absent with those parts pure buffy-yellow. In 

 some specimens the caudal tibia? are inclined more or less strongly 

 toward glaucous. 



At Summit House the species was scarce and extremely active, 

 being found in short, dry grass and tarweed under a scattering growth 

 of oak. At Raymond it was taken in stubble and was not common. 

 The contrastingly colored tarsi are very conspicuous in life. 



Ligurotettix coquilletti McNeill. 



A series of forty-nine specimens from localities in the Mohave and 

 Las Vegas Deserts are referred to this species, to which L. kunzei 

 Caudell from southern Arizona is closely related, differing only in 

 the average larger size and slenderer caudal femora. The series is 

 distributed as follows: Cottonwood, September 9, 2 cT, 1 9 ; 

 Kelso, August 12, 4 d\ 2 9 ; Cima, August 12, 3 d\ 3 9 ; North 

 Range, Providence Mountains, August 12, 1 9 ; foothills Bird Spring 

 Mountains, California and Nevada, August 11, 12 d\ 9 9,1 immature 

 individual; Las Vegas, Nevada, August 10, 9 d\ 2 9 . 



In size there appears to be considerable geographic variation, 

 Cima individuals being quite small, while the largest female of the 

 Bird Spring Mountains series and of the two of that sex from Kelso 

 are almost as large as individuals of L. kunzei. Individual variation 

 is also quite marked in the Bird Spring Mountains series and the two 

 Kelso females are rather different in size, one of the four males from 

 the latter locality also appreciably exceeding the others from that 

 region in size. Average specimens from the various localities measure 

 as follows :
