SCUDDER. — NORTH AMERICAN CEUTHOPHILI. 43 



a transverse bar ; a transverse anterior series of four testaceous dots ; 

 on the other thoracic segments appearing in large anterior latei-al 

 spots more or less confluent ; legs fusco-testaceous, becoming luteous 

 apically, the hind femora testaceous with scalariform fuscous markings, 

 the other femora darker apically than at base. The antennie are 

 tolerably stout at base but soon taper to a delicate thread and are 

 about three times as long as the body, and the legs moderately long 

 and slender. Fore femora no stouter than the middle femora, nearly 

 half as long as the hind femora, and more than a third longer than 

 the pronotum (^ 9)i the inner carina armed with 2-3 spines, the 

 subapical very long. Middle femora similarly armed on the front 

 carina, and on the hind carina 1-2 moderate spines besides a very 

 long genicular spine. Hind femora a little more than twice as long 

 as the fore femora, moderately slender, being almost three and three 

 quarters times as long as broad ((^), the apical fourth subequal, the 

 surface with no raised points, the outer carina entirely unarmed except 

 for 4-5 very distant slight recumbent serrations on the apical half, 

 more distinct in the 9 than in the (?, the inner carina with a few 

 raised points, the intervening sulcus narrow. Hind tibiae straight in 

 both sexes, slender, fully a tenth longer than the femora, armed 

 beneath with two median subapical spines besides the apical pair ; 

 spurs subalternate, the basal at or beyond the end of the proximal 

 fourth of the tibia, more than twice as long as the tibial depth, set at 

 an angle of about 80° with the tibia and divaricating about 150°, their 

 extreme tips incurved ; inner middle calcaria very much longer than 

 the outer, about twice as long as the others, or as the spurs, and just 

 about as long as the first tarsal joint. Hind tarsi more than two fifths 

 the length of the tibiaj, the first joint longer than the rest together, the 

 second three times as long as the third, and as long as the fourth. 

 Cerci slender, tapering, a third as long again as the femoral breadth. 

 Ovipositor two thirds the length of the hind femora, faintly arcuate 

 throughout, equal from close to the base, moderately broad, the tip 

 scarcely upturned, acutangulate (about 40°), the inner valves feebly 

 crenulate, the prominences slightly accentuated.
