an incision bearing five or six sliorf heavy Ijristles. Above tliese there are some 

 hairs. The dorsal jiaired bristles of the tibiae are accompanied by two rows of 

 heavy bristles, the dorsal row standing close to the dorsal pairs. The longest 

 apical bristle of the foretibia reaches nearly to the apex of the second tarsal segment, 

 while that of the hindtibia e.xtends to the apex of the first segment. The longest 

 apical bristle of the first hindtarsal segment extends to the apex of the second, 

 and that of the second to the apex of the fifth. The first hindtarsal segment is a 

 little over half the length of the tibia. The first midtarsal segment is longer than 

 the second. The fifth segment bears fonr bristles on each side, besides a snbapical 

 hair. The claw is slender. The measurements of the tarsi are as follows : — 



Modified Segments. — The eighth sternite of the <S is large, bearing nnraerous 

 hairs. It is emarginate below at each side. The clasper (PI. XII. fig. 50) is 

 produced into two small lobes, the upper one bearing a long bristle. On the lower 

 one there are several short hairs and one long one. The finger (f) is long, curved 

 downwards at the apex, and bears some fine hairs at the end. The manubrium (m) 

 is large, elongate-triangular, with the tip curved upwards. The ninth sternite is 

 (apparently) not divided ventrally (PI. XIII. fig. 64). It bears five bristles just 

 before the apex and two farther basad, besides some fine hairs. The spiral of the 

 penis lias a single whorl. The eighth tergite of the ? projects backwards above. 

 It bears a number of rather heavy hairs above the stigma. The bristles on the 

 lower half are numerous (PI. XII. fig. 57). The stylet is very long and slender, 

 being at least seven times as long as it is broad.

Similar to C. agrippinae, but diflering from it in the following characters ;— 

 Head.— The rostrnm is longer, the last segment being nearly twice the length 



of the fourth segment of the maxillary palpus. 



Abdomen.— The bristles on the abdominal tergites are numerous. The seventh 



tergite bears three long apical bristles (?), of which the uppermost is longer than 



in C. aqrippinae. The teeth in the combs of the abdomen are fewer in number, the 



numbers being : —
