146 Mr. W. F. Kirby on the Family Iletrodidaj. 



2 to 6 tliere arc three small warts between tlie middle and 

 lateral spines and a single one below each of the lateral 

 spines, and the space around and between the spine and 

 warts and the centre of the under surface of the abdomen is 

 finely and transversely striated. Anal appendages testaceous, 

 tipped with reddish ; upper ones upcurved at the extremity, 

 and with a large blunt subserrated pyramidal elevation nearer 

 the base ; lower appendages straight, moderately slender, 

 pointed, about as long as the up])er ones. 



Male. — Similar but smaller ; reddish, varied with black ; 

 pronotum irregularly banded and marked with black in the 

 middle, behind the lateral projections, and on the sides; on 

 the abdomen there are irregular double black bands in the 

 middle and on each side, and there is one row of conspicuous 

 warts between the central and lateral spines, the others being 

 more slightly indicated in the female. Femora black above, 

 with longitudinal rows of red spots. 



Collected by Miss Anna Howarth in E. Karoo, Cape 

 Colony, in September 1896. There is another specimen in 

 Mr. W. L. Distant's collection from near Grahainstown. 



Jn A. cervinuSf Burm., and ^1. militaris^ White, the spines 

 round the hinder part of the pronotum are much smaller, more 

 numerous, and closer together. 



Genus Hemihetrodes, Pictet. 



Pictet describes his //. Peringneiji as having the abdomen 

 black above, or with three black bands. The latter form will 

 sink as a synonym of //. vittaius, Walk., but the name 

 //. Peringueyi may be retained for the form with a black 

 abdomen, whether it ultimately proves to be a species or a 

 variety. Pictet's suggestion that IJctrodes Bachman?n, JL-^rsch, 

 may be a lleniihetrodes is inadmissible, for Karsch cannot 

 have failed to notice whether the tibial cavities were open or 

 rimate ; and they are evidently intended to be represented as 

 open in his figure of //. Bachmanni. 



Genus Aphractia, nov. 



WEnyalius, Stfil, CEfv. Vet.-Akad. Fcirb. xxxiii. (3) p. 58 (1876). 

 Evyaster, div. a, St?d, Ilec. Ortli. ii. p, 2:i (1874). 



This genus, which has been fully characterized by Sfal, 

 may be distinguished at once from Acanthoproctus and Hemi- 

 hetrodes by its S))ineless abdomen. The type is Uetrodes 

 diadematus, Stal, of which 1 have no doubt that //. crassipeSj 

 Walk., and Acanthoproctus ihexy Pict., are synonyms.
