broad only, a few scattered raised points beyond tbe middle above, the 

 outer carina uniformly and rather closely serrulate, the inner carina 

 similarly but more delicately armed with a tendency to a biseriate 

 arrangement, the intervening sulcus rather broad. Iliud tibiae 

 straight, shorter than the femora, armed beneath with a single sub- 

 apical spine besides the apical pair ; spurs subopposite, the basal at 

 the end of the proximal fourth of the tibia, nearly half as long again 

 as the tibial depth, set at an angle of about 55° with the tibia and 

 divaricating about 100°, their extreme tips incurved; inner middle 

 calcaria barely longer than the outer, half as long again as the others 

 or as the spurs, and a little shorter than the first tarsal joint. Hind 

 tarsi almost half as long as the tibiae, the first joint about as long as 

 the rest together, the second fully twice as long as the third and with 

 it as long as the fourth. Cerci moderately slender, considerably 

 shorter than the femoral breadth. 



Length of body, 1 0.5 mm. ; antenuie, (est.) 28+ mm. ; pronotum, 

 4.25 mm. ; fore femora, 4.75 mm. ; hind femora, 10.3 mm.; hiud tibiae, 

 9.75 mm.

26. Ceuthophilus sallei, sp. nov. 



Dark mahogany brown, glabi'ous, marked with reddish luteous in a 

 more regular pattern than common, there being a moderately broad 

 mesial stripe of the brighter color, broader on the anterior than the 

 posterior part of the segments, the sides with regularly disposed flecks 

 and dots of luteous, becoming more numerous below, so that the luteous 

 prevails on the lower portion of the sides ; on the abdomen the luteous 

 spots are usually either circular or made of short oblique dashes ; the 

 legs are as dark as the upper surface, the hind femora with the usual 

 pattern, but the lighter portions subdued in tint. The legs are rather 

 short, the antennae not stout. Fore femora stouter than the middle 

 femora, especially on the proximal half, about a fifth longer than the 

 pronotum, at least in the $ , very much less than half as long as the 

 hind femora, the inner carina with a couple of spines, the subapical 

 long. Middle femora with two spines besides a long subapical spine 

 on the front carina, and on the hind carina 0-2 spines besides the long 

 genicular spine. Hind femora fully as long as the body, nearly two 

 and a half times longer than the fore femora, very stout, tapering so 

 that the distal fourth is subequal, nearly three times as long as broad, 

 the inner surface scabrous with a cluster of raised points near the 

 middle above, the outer carina with 8-10 distant unequal serrations or
