their inner (sutural) edges ridged and toothed at the apex. Rach 

 carries a number of strong bristles, three of which are especially 

 prominent. 



The foot-claw (fig. 8) and the arrangement of the abdominal 

 tubercles (see fig. i) have been sufficientl}' described. The fourth 

 abdominal sternum (fig. 9, iv) bears a pair of short conical pro- 

 cesses which represent the spring (fig. (), d) ; just behind these the 

 paired sternal plates of the fifth abdominal segment (fig. 9, v) guard 

 the reproductive aperture. Willem has figured a very similar 

 arrangement of the ventral abdominal surface in Neanura muscorum 

 (1900, pi. viii, fig. 3). 



ENTOMOBRYIDAE. 



Six species of this large family are included in the collection. 

 All belong to the sub-family Entomobryinae, and are distributed 

 among three of its tribes. One species — a Lepidocyrtus of some- 

 what aberrant form — is a member of the Entomobryini ; there are 

 three remarkable Paronellini, all of which can be referred to the 

 type genus Paronella ; finally there are two Cyphoderini ; one a 

 species, Cyphodenis sinmlans, described by Imms, and the other 

 the type of an interesting new genus. 



ENTOMOBRYINI. 

 Lepidocyrtus, Bourlet. 

 Lepidocyrtus caudatus, sp. nov. 

 (Plate Iv, figs. 10-12). 



Mesonotum slightly prominent, half as long again as metano- 

 tum. Fourth abdominal segment six times as long as third, sixth 

 abdominal tergum prolonged into a slender cerciform process (fig. 

 10). Feeler two and a half times as long as head, proportion of its 

 segment as 4 : 8 : 6 : 9. Leg with distinct joint differentiating tar- 

 sus from tibia in second and third pairs. Foot-claw with promi- 

 nent internal teeth, empodium long, acuminate, tenent hair thick 

 and clubbed (fig. 11). vSpring more than half as long as body; 

 dentes i-^ times length of manubrium ; mucro (fig. 12) with strong 

 procurved terminal and dorsal teeth and a slender dorsal spine. 



Length 2*5 mm. Colour pale j^ellow with violet patches on 

 the antennal segments, a violet streak along each side of the 

 head, violet spots on edge of mesonotum, third, fourth and fifth 

 abdominal segments, top of middle and third thighs, base and top

The elongate cerciform tergum of the sixth abdominal segment 

 seems to be the most distinctive feature of this species. It comes 

 rather near to L. imperialis, Carpenter (1916, p. 41) from the 

 Seychelles, L. maximns, Schott (1893, pp. 11-13) from Cameroon, 

 West Africa, and L. pictus, Schaffer (1898, pp. 415-16) from
