tion of the femora, the longest less than a third as long as the tibial 

 spurs, the inner carina with similar but smaller and subequal spines 

 throughout its extent, on both far more delicate in the female than in the 

 male, the intervening sulcus decidedly narrow. Hind tibias straight in 

 both sexes, slender, about an eighth longer than the femora, armed 

 beneath with two subapical spines besides the apical pair ; spurs 

 scarcely subopposite, the basal at the end of the proximal third of the 

 tibia, almost or quite twice as long as the tibial depth, set at an angle 

 ordinarily of 30-40°, but sometimes of more nearly 80° with the tibia, 

 divaricating 100-160°, their tips incurved; inner middle calcaria con- 

 siderably longer than the outer, nearly twice as long as the others or 

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

 almost half as long as the tibice, the first joint as long as the rest 

 together, the second three times as long as the third and with it longer 

 than the fourth. Cerci slender, tapering, half as long again as the 

 femoral breadth. Ovipositor fully three fourths as long as the hind 

 femora, gently and uniformly arcuate throughout, of equal width 

 throughout, the tip not sharply acuminate, the inner valves with a 

 feebly crenulate armature.

8. Ceutbophilus palmeri, sp. nov. 



Dark fuscous heavily blotched and spotted with dull luteous, the 

 lighter markings consisting of a broken mediodorsal stri|)e of gener- 

 ally varying and greater or less width, of very irregular blotches and 

 tortuous streaks on the sides of the pronotum, of large anterior spots 

 on the sides of the meso- and metanotum, and of anterior transverse 

 daslies or belts on the abdominal segments ; the fore and middle legs 

 are fusco-luteous becoming more or less deeply fuscous at the distal 

 extremity of the femora and proximal end of the tibiae, the hind 

 femora fuscous except at base with the usual dull luteous markings, the 

 rest of the leg dull luteous, but the basal half of the tibiae more or less 

 infuscated. The antennae are three or four times as long as the body, 

 and very slender except toward the base, and the legs long and slen- 

 der. Fore femora no stouter than the middle femora, about three 

 fifths as long again as the pronotum and half or less than half as 

 long as the hind femora, the inner carina with 2-4 mostly long spines. 

 Middle femora with 1-2 spines besides a long subapical one on the
