numbers duriusjf May and June, and occasionally in July and August : 

 Chloroclystis dryas, C. indicataria, Venusia verriculafa, Xanthorhoe 

 rosearia (common), X. hicidata, Selidosema dejectaria, S. fenerata, 

 Declana fir>ccosa (common), Epirrantliis alectoraria, E. hemipteraria, 

 and Drepanodes muriferata. It may I think be safely assumed that, 

 with the exception of C. dryas, X. hicidata, and X. rosearia, which 

 are winter species proper, all these insects hibernate in the imago 

 state

A NEW LISTROPSYLLA AND THE J OF CTENOPIITHALMUS 

 CALCEATUS, Waterst. (1912), BOTH FROM SOUTH AFRICA. 



(Plate V.) 



BY THE HON. N. CHARLES ROTHSCHILD, M.A., F.L.S. 



The Eev. James Waterston has requested me to publish descrip- 

 tions of the two species of flea referred to above, which he received 

 from the Eev. R. Godfrey. The type specimen of the new species 

 Mr. Waterston has kindly allowed me to retain. 



1. LisTROPSYLLA CHELURA, spec. nov. (PI. V, figs. 1 and 2.) 



S ? . Near L. dolosus, Roths. (1907), from British East Africa and Uganda. 

 The pronotnm, however, bears only two rows of bristles, the comb contains 

 2U sjjines, the first mid-tarsal segment is half as long again as the second, and 

 the modified abdominal segments also are different. 



The mesonotiim has fewer bristles on the sides between the base and the 

 first row ; the mesopleiira bear from 1 1 to 16 bristles and the metepimerum 

 from 15 to 20. The 7th abdominal sternite has from 9 to 12 bristles in the S 

 most of which are small, and 34 in the ? . 



Modified Segments — ^ . The eighth sternite (PI. V, fig. 1, viii, st.) has 

 far more bristles than in L. dolosus, there being a snb-apical row of four or five 

 or six vei-y long ones, and in between and proximally to that row about 20 

 smaller bristles. The clasper and ninth sternite agree in the general outline 

 with those of L. dolosus, but are mvich broader, and their structure is very 

 different in the detail. The clasper somewhat resembles a boot with the sole 

 and heel directed distad and the toes upwards. The sole bears a row of thin 

 bristles and the heel one large bristle accompanied by a smaller one. Tlie 

 movable process F. (pi. V, fig. 1 F) is curved as in L. dolosus, but broader, and 

 the large bristle placed at its ventral margin is much longer and thicker. The 

 ninth sternite (IX.st.) is particularly characterised by the horizontal arm 

 bearing beyond the centre, where it is feebly elbowed, two very strong bristles,
