head and thorax are distributed as sIkiwii in mir fi<rnres (PI. XIII. fig. 5. 6). Those 

 on the abdominal tergites are very numerous, representing three or four rows in the 

 centre, while tlie sides are covered with bristles from near the base to near the 

 apex. The posterior bristles of the seventh tergite are more distinctly j)rolonged 

 tlian the corresponding bristles of the previous segments, but are less than 

 double the length of tlie other bristles. Tiie c? must be expected to have fewer 

 bristles. 



The proboscis (PI. XIII. lig. (5) consists of three segments, the apical one being 

 longer than the first and second together. All the tarsi have three segments. We 

 give an enlarged drawing of the right hind tarsus (PI. XIII. fig. 7), whicli shows the 

 characteristics of the claws very well. The small claw of injctcriills has a large 

 basal tooth, which is but vestigial in the previous two species. It will be further 

 noticed that the pseudo-articulation of the second segment is only indicated on the 

 dorsal side of the segment and is placed much nearer the apex than the base. In 

 this all the forms of Eocteiies differ from Poh/ctenes, in which the psendo-joiut is 

 distinct all round the tarsus and has a more proximal position. The larger pro- 

 portion of the inner surfaces of the mid and hind femora is devoid of bristles. 



Immature specimen (PI. XIII. fig. 8 ; text-fig. I).— A single immature specimen 

 was obtained together with the adult females. It differs in many points from the 

 adults, the most striking being the absence of the pronotal comb, the shortness of 

 the prouotum, the different shape of the elytra, and the lesser number of bristles. 

 The most interesting parts of the example are the elytra, which, unlike all the other 

 immature Polycteuids which we have seen, have a narrow sutural slit, like adults, 

 and a comb. As one of the females contains an embryo in which only the first 

 comb is developed (besides the gular one), the dorsal combs appear in nycteridis in 

 the individual life in this succession : first, third, second. The immature specimen 

 has apparently moulted quite recently, no new bristles or spines being as yet 

 visible under the skin. The tarsi consist of two segments, the second segment 

 bearing near the base an incomplete atlditional articulation (PI. XIII. fig. S). The 

 basal tooth of the smaller claw is not nearly so large as in the adult. 

 The British Museum collection contains: 



4 ? ? and 1 immature specimen, taken oft' a bat on the Moftat Road, Entebbe, 

 Uganda, by Mr. E. Degan. 

 In other collections : 



1 ? in the National Hungarian Museum at Budapest, from fihirati, on the east 

 shore of Lake Victoria, oft' JSycteris hixij'tda. 



3. Genus : Adroctenes gen. nov. 



Latus, clijieo ad latera spinis crassis loco setarum instructo; rostro (^uadri- 

 articulato articulo penultimo brevi ; anteunis capitis basin altingentibus baud 

 superantibus, articulo secundo ctenidio longitudinali armato ; pronoto valde trans-

 brevibns, tarsorum articulo apicali ctenidio ventrali armato, unguilius basi baud 

 distincte dentatis. Genotypus : xV. horcutlii spec. nov. 



The species for which we erect this genus is so different from all the other 

 Polycteuids that a generic separation is amply justified. 



Adroctenes agrees with the American genus Hesperocteiies in the second 

 segment of the antenna bearing a comb, in the pronotuni being transverse and
