SCUDDEB. NORTH AMERICAN CEUTHOPHILI. 39 



tibiae straight in both sexes, fully a tenth longer than the femora, 

 armed beneath with 1-2 subapical spiues (one sometimes paired) 

 besides the apical pair ; spurs subopposite, the basal at about the end 

 of the proximal third of the tibia, slightly longer than the tibial depth, 

 set at an angle of 50-60 with the tibia and divaricating about 120, 

 their tips much incurved ; inner middle calcaria very much longer than 

 the outer, fully twice as long as the others or as the spurs and nearly 

 as long as the first joint of the tarsi. Hind tarsi two fifths as long as 

 the tibia?, the first joint about as long as the rest together, the second 

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

 fourth. Cerci slender and delicately tapering, a quarter as long again 

 as the femoral breadth. Ovipositor more than half as long as the hind 

 tibiae, the lower margin straight, not stout and gently tapering in the 

 basal half, slender and equal in the apical half, the tip upturned and 

 bluntly acuminate, the teeth of the inner valves triangular and rather 

 long, straight. 



Length of body, 19 mm., 9 23.5 mm. ; antennae (est.), $ 90 mm. ; 

 pronotum, ^9 6.7 mm.; fore femora, $ 11.25 mm., 9 10.75 mm.; 

 hind femora, <J 22.8 mm., 923.4 mm.; hind tibiae, $ 25 mm., 925.6

This species is not far removed from G. gracilipes in structural 

 details, though with much duller and less diversified markings. 



7. CEUTHOPHLLUS SECRETUS, sp. nov. 



In markings this species agrees altogether with O. palmeri except 

 that the luteous colors are clearer and that the abdomen is more com- 

 pletely fuscous, the luteous being almost entirely confined to a narrow 

 stripe across the anterior margin, not seen when the segments are 

 contracted. The antennae are fully three times the length of the 

 body, slender and gradually tapering, the legs long and slender. 

 Fore femora scarcely stouter than middle femora, considerably more 

 than half as long again as the pronotum and about half as long as the 

 hind femora, the inner carina with 1-3 small spines. Middle femora 

 with 2-4 spines of varying length on the front carina, and on the hind 

 carina occasionally a single small spine besides the long genicular spine. 

 Hind femora nearly as long as the body, about twice the length of the 

 fore femora, tapering with no abruptness, nearly four times as long as 

 broad, the apical fourth subequal, with scattered but nowhere numerous 

 minute raised points on the upper apical half, the outer carina with 

 small but rather coarse unequal spines, mostly next the narrower por-
