SCUDDEB. NORTH AMERICAN CEUTHOPHILI. 85 



than the femora, slender ; if armed beneath, so slightly as not to be 

 seen with an ordinary hand-glass ; spurs subopposite, the basal at 

 about the end of the proximal third of the tibia, rather longer than 

 the tibial depth, set at an angle of about 35 with the tibia and divari- 

 cating about 70, their tips scarcely incurved ; inner middle calcaria 

 considerably longer than the outer, twice as long as the others or as 

 the spurs, but shorter than the first tarsal joint. Hind tarsi almost 

 half as long as the tibiae, the first joint not so long as the others com- 

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

 than the fourth. Cerci slender, tapering, finely pointed, slightly 

 longer than the femoral breadth. Ovipositor straight, considerably 

 more than two thirds as long as the hind femora, gently tapering in 

 proximal, slender in distal half, the tip upturned to an excessively fine 

 point, the teeth produced, triangular, subaculeate. 



Length of body, 9 7 mm. ; pronotum, 3 mm. ; fore femora, 3.1 mm. ; 

 hind femora, 6.1 mm. ; hind tibiae, 7 mm. ; ovipositor, 4.4 mm.

43. CEUTHOPHILUS CRASSUS, sp. nov. 



Specimens preserved after immersion in alcohol are dark fuscous 

 and very dull castaneous, the former prevailing, the latter seen on the 

 anterior borders of the abdominal segments in a median thoracic line, 

 irregular transverse bands on the middle of the meso- and metanotum, 

 and irregular blotches on the pronotum, mostly sublinear and very 

 angular ; the legs are prevailingly dusky except at base. Antennae 

 imperfect in all specimens but probably twice as long as the body. 

 Legs rather short. Fore femora distinctly broader than the middle 

 femora, but little longer than the pronotum and much less than twice 

 as long as the hind femora, the inner carina with two small semi- 

 recumbent spines, one of them subapical. Middle femora with 3-4 

 small spines on the inner carina, one subapical, and on the hind carina 

 3-4 similar spines besides a small genicular spine. Hind femora con- 

 siderably more than twice as long as the fore femora, much shorter 

 than the body, stout, tapering to the tip with no pregenicular constric- 

 tion, scarcely more than two and a half times longer than broad, with 

 a very few scattered raised points on the upper surface apically, the 

 outer carina finely and sparsely serrulate throughout, more densely in 

 the $ than in the 9 } the inner carina similar, the intervening sulcus 

 narrow. Hind tibiae straight in both sexes, scarcely or no longer 

 than the femora, moderately stout, armed beneath with a single sub- 

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