with miuute denticulations, the intervening sulcus not broad. Hind 

 tibiae considerably shorter than the femora, straight, stout, armed 

 beneath with a single small preapical spine, besides the unusually long 

 apical pair ; the four pairs of spurs are opposite or subopposite, the 

 basal near the end of the proximal third of the tibia, regularly increas- 

 ing in length distally, so that the last are as long as the nearest calcaria, 

 while the proximal are but little more than half that length or than 

 the tibial depth, set at an angle of 70-80 with the tibia and divaricat- 

 ing only about 20, the whole feebly incurved, the tips not more so ; 

 the spurs are also more closely crowded on the distal half of the tibia 

 than before it, and indeed so crowded as to have no intervening spines, 

 which even between the others are few in number and irregular, the 

 two distal spurs with the proximal calcaria being at uniform distances 

 apart, a distance hardly one half that which separates the preceding 

 spurs ; all the calcaria are subequal in length, those of opposite sides 

 similar, but they decrease slightly from above downwards, and the 

 longest is as long as the first to third tarsal joints combined. Hind 

 tarsi hardly more than a third as long as the tibiae, the first and fourth 

 joints subequal and either of them much longer than the subequal 

 second and third joints combined. Cerci moderately stout, equal and 

 single jointed in proximal half, tapering pointed and multiarticulate 

 beyond, the whole about as long as the width of the hind femora. 



Length of body, 15 mm. ; antennae, 29+ mm. ; pronotum, 4.3 mm. ; 

 fore femora, 5 mm. ; hind femora, 10 mm. ; hind tibiae, 9 mm.

PHRIXOCNEMIS BELLICOSUS, sp. nov. 



Vertex smooth. Rather bright luteo-testaceous, subglabrous, very 

 broadly marked with blackish fuscous especially in a broad anterior 

 bordering to the pronotum, and a broader or narrower posterior bor- 

 dering to all the segments, relatively broader on the abdominal than 

 on the thoracic segments, but on the latter sometimes reinforced by a 

 stout mediodorsal stripe deeper in color posteriorly than anteriorly ; 

 the interior edges of the anterior and posterior borderings of the pro- 

 notum are very irregular, and particularly show subdorsal posterior 

 thrusts of the anterior, and laterodorsal anterior thrusts of the posterior 

 bordering; the lower borders of the thoracic segments are broadly 

 luteous and immaculate ; the legs are luteous, the femora infuscated 

 more or less especially beyond the middle, the hind pair with more or 

 less distinct scalariform markings. The antennae are slender and 

 about three times as long as the body, and the legs short. Fore
