256 THE entomologist's record. 



ment of the posterior legs I saw the free lobes; it was a Decticid, an 

 all-green Decticid. A careful examination among my takings showed 

 a second pair, already in my possession, noted of course as Locuata. 

 As a matter of fact they are referable to the interesting genus (rauiji- 

 socleis. It is a remarkable thing that hitherto I had known of no 

 single all-green Decticid, and yet here at Geok Tapa in one week j 

 had taken two, both new to science. In the Zoological Museum at 

 Petrograd, I afterwards found Adelung's type of (Ta)iipsocleis nssnri- 

 ensis, which is a third all-green Decticid, indeed, the first one described, 

 I know of no others. My species is remarkably close to G. ii!<miriensu, 

 from the valley of the lower R. Ussur, near Vladivostok, a long cry 

 from Geok Tapa. Yet the difference seems quite slight; the new, 

 species differs in the absence of two dark markings on the frons, in 

 the black-ringed antennae, well-marked edges of the pronotnm, which 

 is decidedly compressed, and in the strongly pubescent anal segment 

 of the male, with median nicisions, and in the armature of the pos- 

 terior femora, which have only five or six black spinules on the under 

 surface and on the mner margin only. The female has the subgenital 

 plate obtusangular with broad obtnsangular lobes, and in the middle 

 of the disc a raised obtusangular lobe, soldered to the disc. I should 

 add another difference between the habits of this species and those of 

 L. viridissinia ; Gaiii])soclt'ix, sp. n., stridulates in the latter part of the 

 afternoon, and ceases at sundown, just when the evening chorus of 

 Lociista bagi.ns with gradually increasing intensity. 



In the same field there are several species of Plati/cleis of the P. 

 i/risea group, e.tj., P. (jrhea, L., P. assimilis, Fabr., and a third species 

 which I have not yet identified ; an addition to the local list was 

 I'lati/pterna tibialis, F. de W., of which I took a single male by chance 

 sweeping that same afternoon. 



Acrida tiinita was just maturing when I left, und P!j>acro)iiia 

 thalassina, Rossi, had begun to be a nuisance ; I always felt obliged to 

 catch a lot to see if there were not some E. teri/estuia among them, 

 especially on the salt marshes. U'^dipoda caotilescenfi, L., and the 

 beautiful <^. salina, Pall. (= (jratiom, Serv.), and Acmti/lns patruelis^ 

 Sturm., were just beginning to appear in numbers. The burning sun 

 brought all those forms on very early; Ave are accustomed in our 

 latitudes to look upon Decticids as a late maturing group, and in 

 England (J. ()riseo-aptera stridulates away merrily late into October, 

 but seldom appears adult before the late middle of August ; yet at 

 Geok Tapa, O. indistincta was in full maturity in the second week of 

 July, and I did not see an immature specimen. The other local 

 Decticids, e.t/., the four species of Plaiijchi^ and Dectims albifvonn 

 were also fully mature ; in the first few days there I found one or two 

 nymphs of the Plati/deis, and saw a 7 '(^(V/r^.s emerging from a nymphal 

 skin ; yet on July 23rd, at Mtskhet, at the junction of the Aragva and 

 Kura, eighteen versts above Tifiis, I found I'aradii/madKsa sordida, 

 Herm., only in the nymph stage. Perhaps the junction of the two 

 valleys at this point, with two rapid streams, keeps the air cool, for 

 Mtskhet is a favourite summer resort for the residents of Tiflis, 

 although the difference in altitude is trifling. 



Gryllot-aljia (/rijlloudpa, rather smaller than our West European 

 specimens, is common in the garden at Geok Tapa, and sometimes 

 flies to light ; Tridactylns varie;iatiis, Latr., Avas just appearing on the
