areas on the internal face, one proximal, one distal, one premedian, 

 one postmedian, the base color here pale greenish yellow, external 

 face with two more or less distinct oblique bands, dorsal face with 

 the bars of the internal face continued more or less distinctly upon it, 

 ventral face dull yellowish with a distinct preapical black band and 

 occasionally ( 9 type) a median one is more or less distinctly indi- 

 cated; caudal tibiae glaucous, cream colored proximad with the gen- 

 icular section blackish on the internal face, spines with their apical 

 halves black; caudal tarsi pinkish_ochraceous. 



Measurements. 



& 9 



Length of body 20.5 mm. 27.0 mm. 



Length of pronotum 4.0 " 5.5 " 



Length of tegmen 21.5 " 29.0 " 



Length of caudal femur 11.5 " 15.0 " 



A series of five male and three female paratypes have also been 

 examined. These exhibit a slight amount of variation in size and an 

 appreciable amount of difference in the intensity of the depth and size 

 of the tegminal color blotches and in the intensity of the femoral 

 bars. The wing bar is variable in intensity, but not in position or 

 extent, and the general pale color varies only in two lines, i.e., one 

 toward a more pinkish type, the other toward a more distinctly ochra- 

 ceous shade. The dorsal section of the frontal costa is distinctly sulcate 

 in the majority of the paratypic males, but this is not nearly so apparent 

 in the females. In one of the few specimens in which a median blackish 

 spot is present on the ventral sulcus of the caudal femora it extends 

 distinctly toward the base. 

 Trimerotropis laticinota Saussure. 



One female. July 25. 



This specimen has the left tegmen considerably aborted, its length 

 being but three-fourths that of the normal right one. 



Trimerotropis vinculata Scudder. 



Ten males, fourteen females. Several dated July 25, remainder 

 not dated. 



One specimen has the head, thorax and abdomen hoary, while the 

 majority of the series are slightly darker and more contrasted in 

 coloration than the usual type, the markings being blackish brown. 



Circotettix oarolinianus (Thomas). 

 Three males, one female. July 25. 

 These specimens are similar in size to a pair from Soda Springs,
