jiointed 1111(1 (itliers trinicatc niiil dontatc, as our figures show. The insect can 

 so move the organ tluit it is dirt'ctcd downward. We ascertained its use liy 

 observing the live larva under a lens. When the faeces leave the anus tlie rake 

 i.s employed to push them outside and give them a final jerk, whicli sends tliem 

 rolling off the anal segment. 



Small peculiarities like this are often a good guide in determining the 

 relationshi]! of the species, and we had hoped to find some such kind of rake 

 among the larvae (in alcohol and inflated) which we have of the Zygaenids, 

 Liraacodids, and Megalo]iygids, but did not observe it anywhere. 



In fig. B the rake is drawn as if its base could be seen through the supra-anal 

 lobe of tlie last ring, which is not the case. In dead s]iecimens the entire rake 

 can only be seen jihiinly by lifting the supra-anal lobe. 



SOME ADDITIONAL XOTES ON FLEAS DEALT "WITH IN 



PREVIOUS PAPERS. 



By the HON. N. CHARLES ROTHSCHILD, M.A., F.L.S. 



DE. BAKER has ceded to me the Siphonaptera which were recently in his 

 possession. We find among this material a pair of Baker's Pule.x 

 hrasiliensis, which in 19n7 we considered to be probably identical with Xenoi/.sylla 

 cheopis Rothsch., and treated it as such. The two specimens of brn.silie/isiti, 

 however, prove that this identification was erroneous. The insect is the same as 

 ^enoprnjlla rigetus Rothsch., described in 1909 from South Nigeria in West Africa. 

 The latter name, therefore, sinks as a synonym of brasiliensis. The species is 

 doubtless an African one which was imjiorted into Brazil, very likely at the 

 time when the slave-trade was flourishing.
