We here select a single type the largest female from San Fran- 

 cisco, California. 



This species is closely related to 6". loiigispina, though of very de- 

 cidedly different general appearance from the normal condition found 

 in that species. The most striking features are : the very small size ; 

 distinctly and heavily marked occiput and pronotum, and reduced 

 armament of the less strongly developed caudal femora, both in size 

 of distal spurs in proportion to the metatarsus and average fewer 

 number of spines on the dorsal margins. Certain series of longi- 

 spina, in the later instars preceding maturity, and in consequence 

 with genitalia as in the adult condition, closely resemble material 

 of the present species. These agree in size and the more quadrate 

 ironotum, but differ in the more slender form, usually more decided 

 tawny pronotal marking (plate VII, fig. 7) slightly more elongate 

 limbs and the other features which distinguish loiigispina, as discussed 

 above. 



The caudal tibiae have the dorsal surface weakly concave distad in 

 the females, deplanate in the males. The males have the limbs dis- 

 tinctly longer than the females, this most pronounced in the caudal 

 femora. 



In the twelve known specimens of the present species, all now 

 before us, the spine count for the dorsal margins of the caudal femora 

 is the same: internal, 3 and 3; external, 2 and 2. The species is 

 known from so few specimens that little can be ascertained as to its 

 variability. Though variation doubtless occurs, if, as is indicated by 

 the collections of Orthoptera made up to the present time, the present 

 insect is decidedly limited in distribution, probably much less varia- 

 tion will be encountered than in the other widely distributed forms. 



The measurements given above are all from material which shows 

 genitalia of mature form. As such occurs, however, in individuals of 

 the genus in the later instars preceding maturity, in the absence of 

 larger series of the present species we are unable to state positively 

 that these specimens are fully mature.
