deosely pnnctnrcd, each i)Uiicture bearing a very fine and extremely short hair. 

 The second segment of the maxillary palpns equals the fonrth in length, being 

 nearly twice as long as the third. The rostrum reaches a little beyond the apex 

 of the coxa. The labial palpus consists of five segments, of which the first is 

 the longest and the second the shortest. 



Thorax. — The pronotnm bears two rows of hairs and a comb of twenty -one 

 teetli. The mesonotum bears three rows of hairs, besides numerous short ones 

 near the base and two hair-like spines near the apex. On the metanotum there 

 are two rows of hairs, with a few in front. The metathoracical rpimerum bears seven 

 bristles (2.3.2.) and two or three fine hairs in addition. 



Abdomen. — The first abdominal tergite has three rows of hairs and a few 

 in fnint, while the following segments bear only two rows and an abbreviated 

 third one. On the seventh tergite the number of hairs is much reduced, the anterior 

 rows being represented by a few hairs only and the posterior row of longer bristles 

 hardly extending half way down to the stigma. There are two apical bristles 

 on the seventh tergite (broken). The first sternite bears a row of fine hairs 

 along the ventral edge, while the steruites 3 to 7 have a patch of bristles standing 

 close together and partly arranged in a curved row, the last one being long. 

 The stigmata are pointed behind. 



Legs. — The lateral and posterior bristles of the forecoxa stand widely apart. 

 The hindcoxa bears three bristles posteriorly at the apex, the third being short. 

 The hindfemur has two bristles ventrally before the apex on the outerside, and one 

 or two behind the basal ventral incision. All the tibiae have a row of ventral 

 hairs, and on the outerside a lateral row of hairs and a subdorsal row of spine-like 

 bristles, these standing close to the dorsal bristles. The longest dorsal apical 

 bristle of the hindtibia is two-thirds the length of the first hindtarsal segment. The 

 fifth tarsal segment bears on each side six bristles and a subapical hair, the first 

 bristle being more ventral and the fourth more dorsal than the others. The 

 ventral surface of this segment is hairy, and bears two spine-like bristles at the 

 apex, these bristles standing widely apart. The apical spines of the hiudtarsus 

 are stout and short, the longest of the second segment not reaching to the apex 

 of the third. The first segment bears eight pairs of short stont bristles at each 

 side. The measurements of the fore- and hindtarsi are as follows : — 



The pygidial plate is long, being highest posteriorly, projecting backwards as 

 iu C. hilli. The stylet is conical, and more than twice as long as it is basally 

 broad. The anal sternite is peculiar, bearing ventrally near the base a transverse 

 ridge or projection, which is beset with long bristles (PI. XI. fig. 42). 



Modified Segments. — The eighth tergite (PI. XI. fig. 42) has some bristles 

 above the stigma and a number of bristles farther down, of which the position is 

 indicated in the figure ; the bristles, however, are nearly all broken in the specimen. 

 The eighth sternite is small and narrowed, bearing a few fine hairs at the apex. 



This species is known from the ? only. We have one specimen from Perth, 

 West Australia (B. H. Woodward). The host from which this specimen was secured 

 is mifortunately not recorded.
