11. Ceuthophilus LATIBULI. 



Ceuthophilus latibuli Scudd.!, lus. Life, vi. 313-314 (1894). 



Dark brownish fuscous, heavily blotched with ferrugineo-testaceous, 

 largely in the form of small longitudinally ovate spots more or less 

 regularly disjiosed on the dorsum, but inclined to become confluent on 

 the sides, and forming blotches on the pronotum, the hind femora dark 

 with two series of longer and an intermediate series of shorter oblique 

 testaceous lines, forming scalariform markings, all the tarsi and at 

 least the distal half of the tibiie pallid luteous. The antennte are 

 slender and fully three times as long as the body, and the legs long 

 and slender. Fore femora slightly stouter at base than the middle 

 femora, half as long again as the pronotum, considerably less than half 

 as long as the hind femora, the inner carina armed with 2-4 longer or 

 shorter spines on the distal half. Middle femora with two or three 

 usually long spines besides a subapical long spine on the front carina, 

 and on the hind carina a very long genicular spine, besides sometimes 

 an additional spine. Hind femora about as long as the body, con- 

 siderably more than twice as long as the fore femora, rather stout, but 

 more than the distal fourth slender and subequal, the whole three ((^) 

 to three and a half { 9 ) times as long as greatest breadth, the surface 

 very finely and uniformly scabrous with delicate raised points on the 

 darker portions, the outer carina slightly prominent, furnished with 

 8-9 rather unequal inequidistant short spines, the longest not half 

 the length of the tibial spurs (^$) or unarmed (9), the inner carina 

 with 13-16 small inequidistant ((?) or 6-8 inconspicuous (9) spines, 

 the intervening sulcus rather deep but of moderate width. Hind tibise 

 much longer than the femora, straight in both sexes, slightly com- 

 pressed at the base, armed beneath with 1-2 median subapical spines, 

 besides the apical pair ; spurs not opposite, the basal generally at or 

 before the end of the proximal fourth of the tibia, nearly or quite three 

 times as long as the tibial depth, set at an angle of about 60° with the 

 tibia and of about 120° more or less with each other, slightly incurved 

 at tip ; inner middle calcaria very slender, considerably longer than the 

 outer, twice as long as the others or as the spurs and considerably 

 longer than the first tarsal joint. Hind tarsi distinctly less than half 

 as long as the tibite, the first joint not nearly so long as the rest com- 

 bined, the second twice as long as the third and with it shorter than 

 the fourth. Cerci slender, delicately tapering, about as long as the 

 femoral breadth. Ovipositor straight, rather slender, from a third to 

 more than one half as long as the hind tibice, the tip hardly upcurved
