the former the darker, the latter extending upon the lateral margins of 

 the fastigium, on the anterior part of which they are supplanted by 

 red ; antennae testaceous near the base, blackish beyond. Prozona with 

 a large central blackish spot on the disk, inclosing a pair of testaceous 

 dots, laterally disposed ; anterior and posterior margins of the pronotum, 

 especially in the female, occasionally enlivened feebly with red; lateral 

 lobes lighter below than above, speckled, with a broad, somewhat 

 broken, black median baud crossing the prozona. Abdomen varying 

 from grizzly to blackish, the posterior edges of the segments dotted 

 with minute longitudinal spots, and some of the posterior segments 

 marked with a central, triangular, testaceous spot, seated on the pos- 

 terior border. Hind femora with the outer face generally altogether 

 black, occasionally lighter and marked with a central, oblique, pale dash 

 above; upper and lower faces pale testaceous, the inner side of the 

 upper face with a pair of black bars; hind tibiae deep purplish at base 

 (with the basal outer tubercle deep red) passing into deep red beyond 

 the middle, the under surface clay yellow; the spines of the basal half 

 pale, of the apical half reddish, all black tipped. Male cerci clay yellow, 

 edged below with blackish ; supraaual plate yellow mesially, blackish 

 laterally. 



Length of body, male, 23 mm., female, 24 mm.; antennae, male, 9.5 

 mm., female, 10.5 mm.; pronotum, male, 5.5 mm., female, 5 mm.; hind 

 femora, male and female, 12.25 mm. 



Thirteen males, 20 females. Sierra Nevada, July 17-22, Baron Osten- 

 Sacken; Mount Shasta, northern California, at forest line, A. S. Pack- 

 ard ; Siskiyou County, California (U.S.N.M. Kiley collection) ; southern 

 Montana, C. Thomas (U.S.N.M. [No. 721]); Montana (tl.S.N.M. Eiley 

 collection); Helena, Montana (L. Bruner); Humboldt Eiver, Nevada, 

 August, S. W. Burrison (S. Henshaw). It is also credited by Thomas 

 to Wind River, Wyoming; to a point 40 miles from Virginia City, 

 Montana, at a height of 8,000 feet; and to the dividing ridge between 

 Idaho and southern Montana. 



Since describing B. opimus, I have been able to compare it with the 

 types of Thomas's Pezotettix obesus and find they are not distinct. The 

 species is very close to B. pinguis, but differs from it in its markings, 

 particularly in its darker antennae, its much less developed median 

 abdominal stripe and its differently colored hind tibiae, and also in the 

 more continuous and more developed median carina on pronotum and 

 abdomen, and the slightly differing abdominal appendages of the male. 

 It is evidently the commonest and most widely spread of the species of 

 Bradynotes.

 (Plate VI, fig. 10.) 



Body similar in form to that of B. Mspida, but with excessively sparse 

 and feeble pilosity. Head full, the vertex gently tumid, the interspace 

 between the eyes twice as broad as the narrowest part of the frontal
