bristles inclusive of the snl>ai)icitl row, tlie anterior row containing less bristles 

 in the ? than in the c?. The rostrnm does not reach to the apex of the forecoxa. 



Thorax. — The pronotnm has a comlj of H'J — 34 spines. The meso- and meta- 

 notnm are very hairy, bearing three or four irregular rows of short bristles in 

 front of the postmedian row of long bristles. The epimernni of the metathorax 

 has 10 to 12 long bristles and a few minute hairs. 



Abdomen. — The tergites are dorsally minutely denticulate, like the thoracic 

 tergites, tlie four first tergites bearing moreover some ajjical spines, like the 

 metanottiiu. They bear three rows of hristles, the first tergite having some 

 additional bristles in front. There are 3 antepygidial bristles on the seventh 

 tergite. The middle one of these bristles is long, the other two being short in 

 the cf, while in the ? the ujiper is short and the lower one two-thirds the length of 

 the central bristle. The basal sternite has a patch of bristles on the lateral surface 

 and several bristles along the ventral margin. The sternites of segments three to 

 six bear on each siile a row of 3 or 4 in the S, and 6 or 7 in the ?, besides a 

 number of small hairs in front of the row. The seventh sternite of the ? is very 

 deej)ly sinuate, recalling C. galUnulae Dale (= newsteadi llothsch.) ; cf. PI. IX. fig. 4. 



Legs. — The hindfemnr has a row of " or 8 bristles on the outer surface, besides 

 some snbapical lateral bristles, and a row of bristles on the inner side. The 

 mid- and hind-tibiae bear four more or less irregular rows of bristles on tlie outer 

 surface. The tibiae and tarsi resemble those of C. styx llothsch. 



Modified Segments. — c?. The eighth tergite is smaller than in other bird-fleas 

 and the sternite much larger. Tliis tergite is produced behind the stigma into 

 a rounded lobe, which bears about 6 very long bristles, and at the ai>ex aliout 

 3 additional smaller ones. The eighth sternite (PI. IX. fig. 5) is rounded and 

 is densely covered with numerous bristles. The process of the clasper is broad 

 and at the a])ex rounded (PI. IX. tig. 4, p). The movable process is very large 

 (PI. IX. fig. 4, f), being broadest at the ajiex. It bears a short stout spine at 

 the upper distal angle on the inside. Tlie ninth sternite is long and slender, and 



lies concealed in the eighth sternite. ?. The eighth tergite bears about 12 



small bristles above the stigma on each side, about 9 small and 6 long ones beneath 

 the stigma, and between this patcli and tlie ventral margin about 10 large and 

 ~4 small bristles. The inner surface of this segment bears some 5 short and stout 

 bristles. The apical edge is short and bisinuate. Tlie stylet resembles that of 

 gallinae in bearing the two lateral bristles in the apical fourth.

Head. — The frons has a row of 3 long bristles before the eye, and farther fnintud 

 another row of (i smaller ones. The occiput bears one bristle behind the base of the
