Uropoda amblyoponae, n. sp. 

 Pis. xxvii.j fig. 2o, and xxx., fig. 46. 

 Yellow-brown. Body about one and one-third times 

 longer than broad, a very faint swelling in middle of- front 

 margin ; dorsum with simple hairs and a submarginal row of 

 about 16 scale-like ones along posterior submarginal groove. 

 Submarginal line extends up to front legs, and is farther from 

 margin than length of anus. Legs short, tarsi slender, tarsus 

 1 with many long simple hairs toward tip, other tarsi with 

 spines about as long as basal width of joint; in front of coxae 

 1 are two large approximate plates (labial plates) hiding the 

 front tarsi. Male genital aperture between coxae 3 circular, 

 not its diameter from coxae 3, a corneous part appearing in 

 each posterior side of opening. Female aperture nearly one 

 and one-half times as long as broad, slightly narrowed behind, 

 the anterior three-fifths much heavier along the margin than

Uropoda apicata, n. sp. 

 PL xxx.. figs. 47 and 48. 



Very similar to U. fraterna, but the internal line in the 

 plate in front of coxae 1 is angulate and pointed in front, 

 and iti the male the genital aperture is between coxae 2 and 

 '3, and there is a hyaline spot each side between the bases of 

 these coxae. Body about one and one-third times as long as 

 broad, broadty rounded at each end ; no hairs above ; in the 

 male the middle of anterior margin is rather incurved ; female 

 genital aperture hardly nearer posterior than anterior margin ; 

 about one and one-fourth times as long as broad, truncate 

 behind, and reaching middle of hind coxae; anus near sub- 

 marginal line; an internal line fully length of anus in front 

 of it; legs very short, tarsi shorter than usual, with short 

 spines, tarsi 1 with hairs near tip. In the male the plate in 

 front of coxae 1 is broader in front ; hind coxae more approxi- 

 mate than in female : male genital aperture more than the 

 diameter from camerostome. Length, '45 mm.
