sitnated more ventrally and proximally. The eighth sternite (st), however, lacks 

 any bristles whatever. 



Length : 2'9 mm. 



Ten specimens (tive males and five females) of this species were received from 

 Mr. Sikora. They were taken at Plaine des Palmes, in the Island of Reunion, on 

 Nyctinomus acetahulosus. 



T. Ceratopsylla caminae spec. nov. (PI. X. fig. 21. 22). 



Head. — Both flaps of the head are acuminate, the second being twice the length 

 of the first. Some very short and fine hairs are scattered irregalarly over the 

 surface of the anterior part of the head. The posterior portion of the head is nearly 

 twice as long (measured laterally) as the anterior part in the <?, while the two 

 portions are of nearly eqnaj length in the ?. 



Thorax. — The comb of the pronotum consists of twenty-four teeth. The 

 mesonotum (when viewed in optical section) is more than twice as long as it is 

 broad (excluding epimernm and episternura). It liears, besides the two slender 

 lateral and snbapical teeth, two series of hairs and a few single bristles. The 

 ejiimerum of the mctathorax (fig. 21, epmV) has one hair below the stigma. In 

 addition to this there are four hairs more ventral in position, two being proximal 

 and two snbapical, and one hair at the apical corner. The metathoracical comb 

 consists of twentj'-three teeth. 



Abdomen. — The comb of the first abdominal tergite is vestigial, having only 

 four short teeth (fig. 21, <'). The number of teeth of the other five abdominal 

 combs is in the $ 24, 21, 18, 17, 18 respectively, and there are a few teeth more 

 in the combs of the ? . 



The sternites of the fourth, fifth and sixth abdominal segments have three 

 hairs on each side in both sexes. 



Legs. — The coxae are elliptical. The hindfemnr has two snbapical hairs, the 

 one placed subventrally, the other laterally. The hindtibia bears one series of 

 lateral liairs on the outer side. The bristles of the legs are short, the longest apical 

 bristle of the hindtibia being little more than one-third the length of the first 

 hindtarsal segment. 



Modified Segments. — The eighth sternite of the male is somewhat bottle- 

 shajied, being rather strongly narrowed from the ajiical third to the end (in 

 lateral view). The narrow apical jjortion is beset with a number of long and short 

 bristles. The clasper (fig. 22) is elongate-ovate, the process P and the finger F 

 taken together. The finger is very narrow and curved. It bears a few thin and 

 short hairs, of which the one situated at the npper third of the convex edge is the 

 most coijspicuons. 



The eighth tergite of the female is truncate sinuate distally, and bears very 

 numerous hairs. 



Length : 2-1 mm. 



We have received three specimens of this interesting species : one male and 

 two /^/«r/^,s-, from Bannertel, West Australia, taken by Mr. B. Woodward of the 

 Perth (West Australia) Museum, on August 2i)th, 1000, from a bat. 



8. Ceratopsylla reductus si)ec. nov. 

 This insect is very closely allied to C. caminae. It is probably the Eastern 

 Australian representative of the latter. It difiers from caminae in the reduced
