than usual: the depth of the marginal surface at about the middle of its 
length is 2-15, and at this point the two surfaces are well inclined: the punc- 
tuations of the marginal and dorsal surfaces are not very coarse and do not 
tend to merge in pairs forming coarser pits. 
A single example from Shiny (about twenty-seven miles E. of Gravelotte) 
probably represents a distinct variety. It is more coarsely punctured on the 
marginal and dorsal surfaces than in other forms of the species, and the 
punctures tend to run together into larger pits. The marginal surfaces are not 
deep, and the ridge of separation is absent anteriorly. The depth of the 
marginal surface at about the middle of its length is i-8, the two surfaces 
being very obliquely inclined to each other at this point: greatest length of 
shield 9-3. 
A fairly typical example was taken at Silwane (about thirty-three miles E. 
of Gravelotte) by Mr G. van Dam. This was accompanied by two very small 
specimens which differ from the larger adult example in presenting sharply 
defined and continuous marginal surfaces, and very flat dorsal surfaces : three 
or four pairs of stiff setae occur on the dorsal surface as in adults. 
Galeosoma pluripunctatum sp. nov. (PI. IV, fig. d ). 
The type is a single adult female example from Mooi Vley, Rustenburg 
dist. (W. Powell). It is closely .related to schreineri from De Aar, and vandami 
from the neighbourhood of Leydsdorp, and may be regarded as a connecting 
link between those. two species. The upper surface of the shield is however 
more closely and finely pitted than in either of the above, and this constitutes 
the most distinguishing character of the species. That surface is quite devoid 
of long stiff hairs or bristles except for a pair in the anterior half — in schreineri 
long stiffish hairs are fairly numerous — and except for the punctures is levelled 
smooth and glossy. The marginal ridge between the upper and lateral surfaces 
is on the whole like that of schreineri : posteriorly it is sharp and slightly up- 
turned, whilst anteriorly it is practically obsolete as a distinct ridge though 
there is a well defined angle between upper and marginal surfaces, this angle 
amounting to only a trifle more than 90° mesially. (In schreineri (PI. IV, fig. c ) 
the ridge itself though blunt is perfectly distinct anteriorly and the anterior angle 
mesially is considerably more than 90° : in typical vandami the ridge is absent 
and the angle not well defined.) The upper surface of the shield is only 
moderately convex, being more flattened than in typical vandami or schreineri. 
The distance between the posterior median eyes is only a trifle greater than 
the distance between the posterior median and posterior lateral: thus it 
approaches schreineri rather than vandami, apparently. However, ocular 
characters are not altogether trustworthy when dealing with a limited amount 
of material. 
Measurements. Total length 17, length of upper surface of shield 8*9, 
breadth of same 8-25, depth of marginal surface anteriorly 1*75, depth of same 
posteriorly i-i, depth of same at the middle of its length 1*65. 
Galeosoma coronatum Hewitt (text fig. 4 e, PI. IV, fig. a). 
Two female examples, representing a fairly distinct variety, have been 
taken on the town lands adjoining the experimental farm at Potchefstroom 
(G. van Dam and A. Roberts). In the original description of this species it 
should have been stated that a true primary marginal surface is present on the 
shield, but is moderately deep only in front where it is clearly separated from the 
more glossy coarsely punctured adjacent surface, although a sharply defined
