The long description of this insect given by Weyenbergb does not fit the two 

 species I describe below, though one of them was sent to me as grossimntris, being 

 thns named, doubtless, because it was found on Dasypm minutus, which is the host 

 given for grossicentris. 



Baker, having overlooked the name ^^nlacopsylla, diagnosed a genus 

 J/cyOyWsyZfa, Ac, basing his dia":nosis on SS and ? ? of what he supposed to be 

 grossiventris. These S <S belong, however, to a different species than the ? ? , if his 

 specimens are really specifically the same as ours. Anyhow, for the present 

 Megapsi/lla must sink as a synonym of Malacopsylla, until it is shown that 

 Baker's two species called by him grossiventris are geuerically distinct from 

 Weyenbergh's grossiventris. 



2. Malacopsylla androcli spec. nov. (PI. VII. tig. 10; VIII. fig. 11. 12. 14. 15). 



Head. — The head (PI. VIII. fig. 11), which is similar in the two sexes, is 

 punctured all over, and bears a small frontal tubercle. A depression situated jnst 

 in front of the eye extends from the antennal groove obliquely forward to the 

 oral edge, separating a broad rounded ventral lobe from the frontal part of the 

 head. At this groove there are two bristles near the eye, one above the other, 

 and two more between them and the oral edge. There are also some hairs at 

 the frontal edge near the maxillary palpus. The occiput bears only two or three 

 subapical bristles on each side, and in the t? two more bristles above the 

 antennal groove. The row of fine hairs along the antennal groove is distinct in 

 the c?, while it is very much reduced in the ?. The second segment of the 

 maxillary palpus is half as long again as the third, and as long as or longer than 

 the fifth, the latter appearing rather strongly rounded when looked at from the 

 flat side, and bearing a number of very short hairs along the inner and apical 

 edges. The rostrum reaches nearly to the apex of the anterior coxa. Its segments 

 2 and 3 are nearly the same in length, 4 is a little longer, and 5 half as long 

 again as 4. 



Thorax. — The prothorax has no comb. It bears a row of very long bristles 

 situated close to the base (PL VIII. fig. 11), a solitary, very long bristle in 

 the middle of the ventral edge above the stigma (st.), and some very thin and 

 short hairs laterally towards the apical edge. On the mesonotum there is a row 

 of numerous very fine hair-like spines near the apex. The mctanotnm, which 

 is much longer than broad, has a row of bristles beyond the middle. The 

 epimernm of the metathorax bears three (c?) or four (?) bristles from the stigma 

 downwards. 



Abdomen.— The abdominal tergites bear each one single row of bristles. The 

 apical bristle of the seventh tergite is long and slender, and is not accompanied 

 by fine hairs on either side. The stigmata are very large and stand just a little 

 above the most ventral bristle of the tergites, but nearer the base. The basal 

 sternite bears a patch of hairs on tlie side, the hairs being more nnmerous in 

 the ? than in the c?, and has in addition a ventral bristle. Tlie stornites of 

 segments 3 to 7 bear a row of three or four bristles, before which row stand 

 several hairs on the sternite of the third segment. The jjygidial plate is trans- 

 verse and mesially divided (PI. VIII. fig. 12).
