hairs on each side. Sternites with cruciform sulci from 2nd to 18th seg- 

 ments, the transverse arm recurved and more deeply impressed than the 

 longitudinal. Anal sternite with strongly convex lateral margins, merging 

 by broadly rounded angles to the slightly emarginat© caudal margin. Coxo- 

 pleurae (fig. 5) with a slightly rounded caudal margin, bearing 3 irregular 

 rows of short setae, pores fairly large, not more than 30 in number, 

 leaving very broad pore-free margins. Femur of penult legs (fig. 4) with 

 setae above and a dense downy pubescence below. Anal legs : femur 

 and prefemur with numerous short sharp setae ; femur 2d times, prefemur 

 2-2 times, and tibia 2-0 times as long as broad ; dental formula 2. + 9 + 4 ; 

 the tooth-bearing margins of tibia and 1st tarsal joint quite straight.

hoc.— Mount Algidus (T. Hall). 



This species differs from C. austral/is, as described by Kraepelin, in 

 possessing spinescent setae dorsally on the anal femur, and in the extension 

 of the tergal sulci nearly to the end of the 20th segment. 



Cryptops dilagus n. sp. (Fig. 6.) 



Pale straw-colour, head slightly darker. Head without sulci, over- 

 lapped by the 1st tergite. Tergal sulci : a pair of incomplete sulci con- 

 verging cephalad on 4th and 5th, complete from 6th to 19th, and extending 

 half-way along 20th. Anal tergite with straight converging sides, triangular 

 projection medianly rounded, lateral angles rounded. Presternum with

anterior margins slightly emphasized, vaguely convex, medianly gently 

 sinuate, a few submarginal hairs but no strong setae. Sternites with 

 cruciform sulci from 2nd to 18th ; transverse arm recurved, longitudinal 

 arm reaching to anterior margin, and half-way from transverse to posterior 

 margin ; posterior portion of the longitudinal arm less distinct. Anal
