Subfamily Diplueini. 



This subfamily is distinguished by having three claws, no rastel- 

 lum, and the lip free. The superior mammillae vary from less than 

 one-third the length of the cephalothorax (Hadromjche L. Koch) 

 to more than the whole length (Cethegus Thorell). The group 

 Masteriece, though represented in New Guinea and the Pacific 

 Islands, has not been found in Australia or New Zealand. 



The genera resolve themselves into fairly definite groups as 

 follows : — 



1. Sis spinnerets Hexatiiele^e. 



Four spinnerets only 2. 



2. Tarsal claws with two rows of pectinations. Inferior 



mammillae near together (not more than 2 diameters 

 apart). Tarsi unbespined. Scopulse on front two 

 pairs of tarsi and at least partially on same metatarsi. 

 No teeth on the outer margin of the falx-sheath. 

 Sternal sigillae of moderate size and marginal. Front 

 row of eyes procurved. Superior spinnerets generally 



not exceeding half the length of the cephalothorax Bkaciiythele.e. 



Tarsal claws with one row only of pectinations 3. 



3. Inferior mammillae widely separated, about 4 of their 



diameters apart. No scopulse on any legs. No row of 

 teeth on outer margin of falx-sheath. Sternal sigillae 

 of moderate size and marginal. Superior mammillae at 



least not much shorter than the cephalothorax Macrotiiele.e. 



Inferior mammilla? close together, about 1 diameter apart. 

 Tarsi of all legs thickly bristled and bespined. Two 

 rows (besides an intermediate at lower end) of teeth 

 on falx-sheath. Sternal sigillae large and removed 

 from margin. Superior mammillae short, hardly exceed- 

 ing two-fifths the length of the cephalothorax Atrace.e. 



Group Beachythele.e. 



The group into which the genera hereunder collected fall is 

 associated by M. Simon with the genus Diplura under the name 

 of Diplureoe. In the first place, however, we have no genera to 

 record folio wing the Diplura side of it. Secondly, as shown by 

 Mr. F. O. Pickard-Cam bridge (Proc. Zool. Soc. Lond. 1896,
