86 THE ENTOMOLOGIST. 



The other European species of the restricted genus Tanio- 

 pteryx known to me are as follow : — 



T. hraueri, Klap. — This species, like putata, has the antennte 

 distinctly moniliform. The male is, however, full winged. The 

 female is very similar to putata female, but the apical marking of 

 the fore wings in hraueri is apparently always quite isolated. 

 Klapalek states that monilicornis, Pict., is a condition of this 

 species, in which the antennse are strongly moniliform and the 

 wings without any transverse markings. Probably hraueri will 

 prove to be a widely distributed species. I have seen it from 

 Bohemia (March, Klapalek) and Spain (<? , Jan. 23, ? , Feb. 11, 

 Navas). Petersen records it from Denmark. 



T. trifasciata, Pict. (Klapalek). — The male has distinctly 

 moniliform antennae ; female, antennae with cylindrical joints. 

 The wings of the male are in a peculiar condition, the fore wing 

 being only about half as long as the hind wing {cf. ' Die Siiss- 

 waseerfauna Deutschlands (1909), Plecoptera,' by Klapalek, 

 pp. 57-8, fig. 88). The male is known to me from a series from 

 Vienna (March 31, 1899, Klapalek). The female I have not seen ; 

 Klapalek describes the wings as " mattgrau, die Spitze und 

 3 fast gerade Querstreifen dunkler." 



T. kempnyi, Klap. — Antennae setiform, with short joints 

 (somewhat moniliform in the male) in the proximal fifth. Full 

 winged in both sexes. In the female especially the bands are 

 fairly well marked, but perhaps as a rule less conspicuous than 

 in putata and hraueri. Apical spot quite small and isolated. 

 Known to me from Switzerland (Dietikon, March 16, Eis), and 

 Lower Austria (Gutenstein, March and April, Kempny). 



T. seticornis, Klap. — Antennae as in risi, slender, with cylin- 

 drical joints longer than broad. Full winged in both sexes, the 

 membrane being less grey-looking than in the other species ; 

 neuration dark and distinct. Transverse markings small but 

 very distinct; apical marking absent or just indicated by a 

 darkening of the tip. The anal veins in the hind wing some- 

 times margined with grey, giving these wings a pretty radiate 

 appearance. It is recorded by Klapalek from the Bohmerwald, 

 Piiesengebirge, Erzgebirge, and Harz (June and July), and I 

 have received a male from the Eastern Pyrenees (Vernet-les- 

 Bains, April 24-May 9, 1909, Dr. Chapman). 



the apex of the dorsal appendage of the supra-anal lobus, seen from side, pro- 

 jects strongly cephalad ; this projection is hardly indicated in the Carpathian

male (fig. a, putata; b, male from Carpathians ; c indicates the direction of 

 the head).
