282 Beetles of the Brevicollis group of Cicindele 
denuded as in religua miht ; in candida the hairs are longer and 
sparsely distributed over the whole surface. The sculpture of the 
head is coarser and has well defined supra-orbital striation ; the eyes 
are also more protruberant. The sum total of these differences quite 
preludes its acceptance as a variety or even near ally of C. candida. 
Dr. Horn places damara, Per. as a variety of neglecta, Dej., and 
also records having received typical neglecta from the same locality, 
i.e., Sandwich Harbour (S.W. Africa). Comparing damara with my 
single female example of eg/ecta, some important divergences are 
shown. (1) The eyes are slightly more protruberant and approxim- 
ate more than those of neglecta and its near relatives discoidea and 
intermedia. (The space between the eyes in these three races is 
usually a little wider than is met with in other members of the group). 
(2) The prothorax and elytra are proportionally shorter, and the 
latter is parallel sided, thus lacking the distinctive elongate oval 
contour characteristic of the females of neglecta, discoidea and anter- 
media. 
On such points, as supra-orbital striation and shape of the labrum 
(the antenne being missing must remain in doubt), damara female 
agrees with neglecta, and may have been correctly placed by Dr. 
Horn, who has had more material on which to found an opinion. 
Per contra it must be conceded that the shape and garniture of the 
prothorax and the eyes of damara are identical with those of my 
reliqua. This may either indicate that the south western forms of 
neglecta approximate to reliqua or (what I think is more probable) 
that the nearest affinities of damara lie with reliqua. 
In conclusion, [ am venturing a few remarks upon the classsification 
and the difficulty of determining the relative specific or sub-specific 
values of this interesting pattern group. ‘The primitiveness of the 
insects included in the group is amply demonstrated by the vast 
range of their distribution, and as a sequence their low susceptibility 
to variation is shown also, by the very limited modifications of 
pattern, form and sculpture that occur. 
These slight and often inconspicuous differences of details are, 
nevertheless, extraordinary stable, and are of greater importance on 
account of the large areas over which they are maintained.
