different from the other two species, .iiicl may well be selected 

 as the type of the genus, which can be dij^tinguishcd by the 

 folhnviuii characters: — 



13road, convex insects ; the tegmina not projecting much 

 beyond the tip of the abdomen, their venation sometimes 

 i)bsolcte in tl»c anal and discoidal fields. Wings with an 

 apical triangle, the ulnar vein ramose. Femora generally 

 stroufjly armnl. Snpra-anal lamina variable, but usually 

 produced. 



Type of the genus P. insularis, Suuss, 



The other siiccics of the genus are P. bipunctata, Wlk., 

 /'. ad'imouialis, ^Vlk. {■=Li(pparia adimonialis), possibly 

 P. latipenn'nf, Hr. { = P/ii///o(lroinia lai'ipennis), and the new 

 species described above. Of the species previously included 

 m the genus, P. puUiduIa, Bol., and P. Viiltzkoiciana, Sauss. 

 & Zehnt., have the supra-anal lamina produced, the abdomen 

 is missing in P. Luneli, Sauss., and in P. hitennedia, Sauss. & 

 Zehnt. ; it is probable that the shape of this tergite is as 

 variable as in the genus PhyUodromia, and too much reliance 

 shouhl not be placed on its transverse form in P. subpecihiata, 

 Sauss. & Zehnt. J and P. antiffuensis, Sauss. & Zehnt. In all 

 these species the armature of the femora is most variable. 

 They cannot be placed in the genus TheganoiHei-yx on account 

 of the ramose character of the vena ulnaris alarum {cf. Trans. 

 Ent. Soc. p. 232, 1906), but the presence of a triangular apical 

 area in the wings does not forbid their entry in the genus 

 Phijllodromia, seeing that this character does occur in several 

 well-marked and well-recoguizcd species of that genus. 

 P. punctulatu, Sauss. & Zehnt., must be referred to the genus 

 Thcganoptery.v.

$ . Head entirely black, with a scanty erect pubescence 

 on the front; ocelli minute, testaceous ; autennai incrassatcd,

 transversely elliptical, anterior border not nearly covering 

 vertex of head ; posterior border more arcuate than anterior,
