hairs near these spines as well as farther proximally. ?. The seventh sternite 



(text-fig. 11, VII. St.) is trancate-emarginate, and bears a small rounded lobe oa 

 a level with the most dorsal bristle of this sternite. The eighth tergite has four 

 or five bristles below the stigma, twelve to fourteen bristles on the ventral portion, 

 and six short ones at the apical margin, the two upper ones of these six being 

 rather stout (text-fig. 11, VIII. t.). The tenth tergite is not separated from the 

 ninth by a suture in either sex. The stylet is about twice as long as it is broad 

 near the base, being bottle-shaped. The receptacalnm seminis has a short head 

 and very long tail. 



Length (mounted specimens) : 1-7 — 2 mm.

?. Closely allied to C. mars Roths. (1898), from Tierra del Fnego, but differs 

 in the genal comb and the seventh and eighth abdominal segments. 



There are only five spines in the genal comb instead of six, a difference which

may not be constant. The seventh abdominal sternite (text-fig. 12, VII. st.) has a 

 more convex apical margin, and the row of bristles it bears is widely interrupted. 

 The eighth tergite (VIII. t.) has more bristles than in C. mars, there being about 

 twenty bristles on each side of this segment, besides those placed at the apical 

 edge. This edge is somewhat angulate above the centre, and bears at this point 

 two bristles on the outer side, the lower one of them being as thick as, but much 

 shorter than, the long lateral bristles. From the angle upwards there are three 

 short stout bristles on the inner side of the segment. The receptaculum seminis 

 has the same peculiar shape as in C. mars and C. ares Roths. (1911), the head 

 being divided by a very deep transverse constriction into two portions, of which the 

 terminal one is nearly globular (text-fig. 12).
