dorsal surface there are usually a pair of large ones placed one on each 
side of the lanceolate mark, about its middle. Towards the posterior end 
smaller ones are arranged to form a series of indistinct chevrons, the 
apices of which point forwards and are in the middle line. On the 
ventral surface these spots are arranged to form four more or less distinct 
parallel rows. 
The females are darker than the males, especially on the abdomen, which 
is usually quite dark brown and in the region of the caput which is 
generally rather deeply pigmented. 
The tibize of the third pair of legs each bear two spines beneath. 
There is nothing characteristic in the size, colour, or facies of this 
species, which in these respects closely resembles C. grisea L. Koch., and 
others of the genus. The species is, however, easily recognised in both 
sexes by the structure of its sexual organs. 
Palpus.—The tibia is pale yellow-brown in its basal half. The apex and 
apophysis are deeply pigmented. 
The apophysis is as usual in the genus placed at the external part of the 
apex of the tibia. It is of the trifid type and is divided into three branches, 
a Superior, an external, and an inferior. The superior branch runs obliquely 
forwards and outwards, and projects on the outer side of the article. Its 
anterior border is at first straight but afterwards slightly concave in 
front. From underneath the straight part a strong bluntly pointed extra 
apophysis projects forward. This is visible in nearly all positions of the 
organ, and is highly characteristic, being found in none of the allied species. 
The external apophysis is inconspicuous, forming a short knob between 
the superior and inferior apophyses and projecting on the outer side of 
the article. The third or inferior apophysis is shaped like a harpoon 
with one barb, as is the case in C. grisea and other species. Here, 
however, the apophysis is longer and rather differently shaped. The 
barb also is longer and slenderer. 
Palpal organs.—The apical organs, whilst resembling those of other 
species, are readily recognisable. The pale external process reaches or 
slightly passes the end of the tarsus. The dark or internal process is 
a good deal shorter. Its external border, for nearly the whole of its 
length, is bent downwards almost at right angles to the body of the 
process. The apex of this bend is obliquely truncated, and from below 
the sharp subtriangular end of the folded over lower border is seen to 
project downwards, forwards and inwards. Behind the external process 
and shining through it is another dark spine-like structure (? embolus), 
and this is different in shape from what obtains in the other species.
