as long as broad in the male and fully three and three quarters in the 

 female, the upper portion of the apical half of the inner surface and 

 to a less degree the upper surface near it with numerous raised points, 

 but not so pronounced as in C. uhleri, the outer carina armed exactly 

 as there but with wider intervals between the larger spines and the 

 spines less stout (<J), or with 2-3 scarcely noticeable spinules near 

 the apex (9 ), the inner carina with about 12-14 serrulations unequally 

 placed, slight, less numerous and distinctly slighter in the female than in 

 the male, the intervening sulcus only moderately broad. Hind tibia? with 

 a hardly noticeable arcuation or sinuation in the male, hardly ( ) or 

 much ( 9 ) longer than the femora, slender, armed beneath with two 

 median subapical spines besides the apical pair; spurs subaltern ate, the 

 basal at about the end of the proximal fourth of the tibia, considerably 

 longer than the tibial depth, set at an angle of about 35 with tho 

 tibia and divaricating 98-100, their apical fourth incurved ; inner 

 middle calcaria considerably longer 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 about two fifths as long as the tibiae, the first joint 

 longer than the other joints together, the second much more than 

 twice as long as the third and with it longer than the fourth. Cerci 

 stout at base, beyond slender, about as long as the femoral breadth. 

 Ovipositor straight, almost two thirds as long as the hind femora, very 

 little enlarged at base, tapering almost throughout but very gently, 

 the tip upturned a little and finely acuminate, the armature as in 

 C. uhleri. 



Length of body, $ 13.5 mm., 9 13 mm. ; pronotum, $ 4.7 mm., 

 94.5 mm. ; fore femora, $ 6.4 mm., 95.5 mm. ; hind femora, cTlo.75 

 mm., 9 13.5 mm. ; hind tibia?, $ 9 16.25 mm.; ovipositor, 8.5 mm.

 York, Riley (U. S. Nat. Mus.). 



Distinguishable from C. uhleri by the slightly different and weaker 

 armature of the carina? of the hind femora, but especially by the slen- 

 derer hind femora, and the narrower inferior sulcus of the same. I 

 probably led Mr. Blatchley into his pardonable error by determining 

 this for him as C. uhleri. 



22. CEUTHOPHILUS SPINOSUS. 



Geuthophilus lapidicola Brunu., Monogr. Stenop., 63-64 (1888). 



Body dark fusco-castaneous, glabrous, with irregular luteous spots 

 and blotches covering a considerable portion of the thoracic segments ; 

 the lower edges of the sides of the thoracic segments are sordid luteous
