can be distinguished from P. germanica L., by the castaneous stripe on the tegmina. 

 the ramose lünar vein of the wings, the notched supra-anal lamina of the male and 

 transverse supra-anal lamina of the female and by tlie produced, and laterally com- 

 pressed sub-genital lamina of the male, with finely cleft apex.

KiUmandjaro: Kibonoto 1,000 — 1,300 metres; Massai steppes. Lower Meru. 

 Usambara: Mombo. 5 c^c?. A cosmopolitan species, which is very variable in size; 

 it can however ahvays be recognized by the from of the sub-genital plate of the male. 

 The lateral margins of this are inflected and the two styles are flattened. The supra- 

 anal lamina is almost hidden by the ninth tergite ; in the centre of the seventh 

 tergite is a circular depression from which rises a bifurcate chitinous structure covei-ed 

 with a fine pubescence and the scent-glands open on either side of this. 



Dr. Sjöstedt's specimens have been compared with three examples in the Oxford 

 ]\luseum determined by Serville himself and though the Kilimandjaro specimens are 

 larger and darker than Serville's specimens {= P. delfa Kirby), I have no hesitation 

 in referring them to supellectilium on account of the identity of structure. The female 

 of P. supellectilium is very different from the male and this sexual dimorphism is a 

 character tliat perhaps entitles this species to generic rank separate from PhyUodromia.

I now think that I was wrong in referring this species to the genus Thegano- 

 pteryx, sens. strict. (cf. Ann. Mag. Nat. Hist. (7) XIX. p. 36. 1907); the ulnar vein 

 of the wing is described as »bi-ramose» not as »bifurcate» and its branches vary in 

 number from three to four. The species also can not be referred to the genus 

 Pseudectobia as defined by me (1. c.) but appears to fall quite naturally into the 

 genus PhyUodromia. Unfortunately it is necessary to find a new specific name for 

 it, since punctulata has already been applied to two species of PhyUodromia, viz. P. 

 punctulaia Beatjvois (1805) and P. punctulata Brunner (1893), for the latter species 

 the name brunneri is suggested. P. zehntneri was previously recorded from Madagascar.
