a\ Hind tibiae armed with five spines* on inner margin above. 



b\ Head relatively small ; hind tibije relatively long, being about 

 or nearly twice as long as the pronotum on the mediodorsal 

 line ; the upper inner spurs of same much longer than the 

 metatarsus longispiua. 



b\ Head distinctly broader than pronotum : hind tibiae relatively 

 short, being hardly or not more than half as long again as the 

 pronotum on the mediodorsal line. 



c\ The apical spine on the inner margin of the hind tibiae markedly 

 smaller than the preceding. 



^'. Hind tibiae subrotundate above, the fourth spine of inner 

 margin (counting from base) more widely separated from the third 

 than the others from their neighbours, those of the outer margin 

 two, rarely three, in number, the upper inner spur as long as the 



metatarsus irregularis . 



d-. Hind tibiae sulcate or subsulcate above, the spines of the 

 inner margin ecjuidistant, those of the outer margin four in number, 

 the upper inner spur much shorter than the metatarsus. .6<//{/<?;v;/V//.y. 



f^ The apical spine on the inner margin of the hind tibiae but little 



or not smaller than the preceding. 



d\ Outer margin with 5-6 spines .fasciatus. 



d-. Outer margin with 2-4 spines ociilattis. 



or. Hind tibias with less than five spines on inner margin above ; head 



not broader than pronotum. 



b\ Hind tibiae with four equal spines on inner margin above, three 

 on outer margin ; head and pronotum nearly uniform castaneous, 



unpictured histrio. 



b.^. Hind tibiae with three spines on inner margin above, two on outer 

 margin ; head and pronotum castaneous, heavily pictured (on the head 

 longitudinally) with dark fuscous pidus. 



I. Stenopelinatus longispiua Brunn.— A well marked species, readily 

 recognized by its long hind tibiae ; the inner calcaria of the same are 

 also exceptionally long, but in this it agrees with the next species. It 

 was originally described from Vancouver Island. 1 have seen specimens 

 from Fort Boise, Or., Suckley ; Drain, Sept. 11, and Roseburg, Douglas 



*Occasionally, by anomaly, there are but fovir spines on one or both legs. See 

 below, under -S". oculattis.
