258 THE entomologist's record. 



restaurants ; in the morning crowds of health seekers stroll about the 

 park, sucking the chalybeate water through bent glass tubes. The 

 hills around reach no great altitude, but are very picturesque and com- 

 mand a fine panorama, although Elbruz is usually only visible in the 

 early morning. On the grassy slopes of these hills I found Fovficida 

 auricularia abundant under stones ; Stauroderns, apricariiis, L., is the 

 common grasshopper, but larvae were still numerous on July 20th ; its 

 habits recall those of OmoceMits viyididns, L., while its voice resembles 

 that of St. hicolor. A grey Platijdeis was not yet mature, and a young 

 Oll/nthoscelis occurred sporadically. The thistle beds and clumps of 

 shrubs sheltered Locusta caudata, Charp. I was interested to note 

 that his stridulation is much deeper than that of L. viridissima, and 

 the song less sustained. 



On the top of the plateau I found a Decticiis vernicivonoi, L., just 

 emerging from the nymphal skin ; the only stridulations audible here 

 recalled that of KpJtippifiera, with a similar peculiar timbre; I traced 

 it down to a glaucous blue Phaneropterid, probably Isojdnja ainpli- 

 penim, that sat and buzzed on the low herbage ; he sits and chirps 

 boldly on the bluish leaves, his long hind legs stretched out con- 

 spicuously. The chirp of (rc/yZZ^.s ccunpestris resounded in the lower 

 ground, and I took a single Grt/Uiis biirdigalensis. 



In butterflies I noticed Fapilin inachaon, Kjiinephele jiotina {janira) 

 and Colias Jujale. I should add that my identification of Lepidoptera 

 is amateurish in the extreme, and very untrustworthy, being only a 

 reminiscence of boyhood days. 



My collecting was now done ; it had been snatched at intervals in 

 a busy time; I had still to return to Tifiis, Kutais and Guria, over the 

 Georgian road, and back again, but had no more opportunity of col- 

 lecting. Retracing the ground gave opportunities of confirming many 

 interesting ornithological, philological, ethnological and geological 

 observations, but that is another story.

By H. DONISTHORPE, F.Z.S., F.E.S. 

 On July 30th last, when hunting for colonies of ^h/rmica scahri- 

 nodh, at Weybridge (to be used for the experiments being carried on in 

 connection with T ycaena avion), I was fortunate enough to discover 

 the above mentioned forms. In one colony, the nest of which was 

 situated partly in the ground and partly under the bark of a fir stump, 

 I found the pterergate. It struck me as being curious as soon as I saw 

 it, and on bottling it I at once perceived what it was. 



Description. 



Head, shape of ? , blackish. 



Thorax pale yellow with some black marks as follows : — Pronotum slightly 

 blackish ; mesonotuni with two round deep black spots ; scutellum present, small 

 but distinct, blackish. 



Two small fovewings are present, which possess traces of veins at the base 

 only, the one on the right measures 2mm. in length, that on the left -Tmm. only. 



The hindwings arc represented by two very small projecting tubercles, which 

 are longer than broad, and are composed of the substance of wings, not being 

 chitinous. Legs pale yellow.
