580 Mr. G. C. Champion on 
centre, the basal margin of the cavity ciliate; eyes not pro- 
minent ; antenne moderately long, rather stout, joints 7-10 
transverse. Prothorax wider than the head, convex, narrowly 
margined, as long as broad; rapidly, obliquely narrowel 
anteriorly and posteriorly, the anterior portion broadly pro- 
duced, subtruncate in front, and depressed down the middle, 
thus appearing sub- bilobed. Elytra moderately elongate. 
Anterior tarsal joint 2 with the comb at the tip black. 
¢. Head iess developed behind the eyes, simple, rather 
convex; antennze very short, more slender; prothorax 
broader than long, rounded at the sides, narrowed posteriorly; 
elytra more widened behind. 
Length 34-45 mm. (¢ ?.) 
Hab. S. Arrica, Prieska (¢ 2: types), Cape Town 
(Dr. Purcell). 
Five ¢ g and one 2 of this species have been sent me for 
determination by Dr. Péringuey, all from the Cape Town 
Museum. 
NoToMALACHIUS, gen. nov. 
Antenne inserted beneath the outer angles of the epistoma 
at some distance before the eyes, 11-jointed, simply serrate 
in the two sexes, joint 2 very short; head rather short, 
simple in g, the epistoma broadly truncate anteriorly and 
confused with the front; labrum short ; terminal joint of 
maxillary palpi oblongo-conic, truncate at tip ; prothorax 
transverse, nearly as wide as the elytra, the latter long, 
subparallel, incompletely covering the abdomen, simple ; 
anterior tarsi 5-jomted, simple in ¢@; tarsal claws with 
membranous lobe; anterior tibiz more or less bowed inwards 
and distinctly widened at tip, more distinctly so in ¢ ; body 
villose. 
Type, Hapalochrus dollmani, Champ. 
The type of the genus, in the absence of the ¢, was pro- 
visionally included by me under Hapalochrus in 1920%*. 
Males of the same species have since been found in the 
collections under examination. The distinctly separated 
short second antennal joint, which is reduced to a connect- 
ing node at the apex of the first in Hapalochrus, s. str., and 
the different ¢-characters, distinguish H. dollmani from the 
last-named genus ; and the broadly truncate epistoma, at 
* H. dasytiformis, Champ. (J. c. p. 188)=Calosotis (?) barkeri, Pic 
(L’Echange, xx. p. 66, 1904). This species has 10-jointed antenna, and 
of course does not belong to the Dasytid-genus Calosotis, Redt., but. the 
name harkeri must be used for it. C. setulosa, Redt., ‘from the Cape, 
the type of which is before me, is very like a Dasytiscus.
