loiiiier than the outer, more than twice as long as the others or as the 

 spurs, and fully as long as the first tarsal joint. Hind tarsi barely 

 two fifths as long as the tibiiv;, the first joint as long as the rest together, 

 the second three times as long as the third and with it as long as the 

 fourth. Cerci not very slender, blunt tipped, about two thirds as 

 lonn as the femoral breadth. 



Length of body, 11.5 mm.; antennae, (est.) 32+ mm.; pronotum, 

 3.75 mm.; fore femora, 4.5 mm.; hind femora, 11.5 mm.; hind tibise, 

 13 mm.

Ceuthophilus nodulosus Brunn., Monogr. Stenop., 64, fig. 33a (1888). 



Luteo-castaneous, heavily marked with blackish fuscous especially 

 along the posterior borders of all the segments and the anterior border 

 of the pronotum, and the latter also flecked with it in an obscure 

 fashion upon the whole disk ; legs luteous, the hind femora almost 

 lacking the usual scalariform markings. The antennae are slender, 

 but are apparently less than twice the length of the body, the legs 

 short. Fore femora very slightly stouter than the middle femora, 

 slightly ((J) or no (9) longer than the pronotum and distinctly less 

 than half as long as the hind femora, the inner carina with a feeble 

 subapical spine, at least in the male. Middle femora generally with 

 3-4 small spines on the front carina, and on the hind carina 0-1 ( 9 ) 

 or 3-8 {$) short spines besides a short genicular spine. Hind femora 

 pretty stout, a very brief apical portion equal, a little less than three 

 times as long as broad, considerably more than twice as long as the 

 fore femora, all the scalariform dark portions of the surface, especially 

 in the male, scabrous with raised points, which are also clustered about 

 the upper portion of the inner side just beyond the middle, the outer 

 carina elevated, with three or four inequal and irregularly distant 

 large and rather coarse more or less arcuate spines, the longest nearly 

 or quite as long as the tibial depth, placed in the middle half, besides 

 a few minor spines beyond them ( J*) or with 4-5 small distant spines, 

 most of them in the constricted part of the femora (9), the inner 

 carina with a series of closer but in no way crowded smaller and uni- 

 form spinules, subobsolete in the female, the intervening sulcus moderate 

 in breadth. Hind tibiae strongly bent or bowed near the middle and 

 subsinuate, on the middle of the proximal half compressed to form a 

 triangular denticle on the under surface, from which a regular curve
