to be difficult, or rather impossible. It is therefore quite admissible, that 

 the moth is an insect imported from China, India, or Ceylon, but, as 

 far as I know, not yet recorded as a tea insect from these countries ^-^). 

 There being yet no summarizing works on the Tineid moths of the 

 Oriental fauna it is nearly impossible to make identifications basing on 

 a simple comparison of descriptions scattered over innumerable publi- 

 cations and written mostly in a defective manner. I therefore give here 

 a possibly full description of materials put into my hands, naming 

 the insect Parametriotes theae, new genus and new species, belonging 

 to the subfamily Coleophorini. 



Parametriotes, new genus. 



Allied to Metriotes H.-S. {Asychna S 1 1.). Scapus without pro- 

 jecting tuft; maxillar palpi developed, five-jointed; fore wing with all 

 veins, except A3, developed; R^, R5, M^ and M2 on one stalk; hind 

 wing with R very short, to costa, and A2+3 absent; upper pair of cal- 

 caria on hind tibia situated at first third of its length; tenth abdomi- 

 nal sternite of the male strongly developed; subscaphium in form of 

 two free spoon-like, or tennis-racket-like, appendages, pectinated laterally. 

 Lamina dentata conical, denticulated. Larva with legs and prolegs, as 

 well as the chaetotaxy of the body normal for the Frenata. Pupa with 

 a pair of leglike processus on ninth sternite. 



Type: P. theae, new species. Habitat; Transcaucasia, Tshakva, 

 near Batum; first and second larval instars mining in the leaves of 

 Thea sinensis Sims, and Camélia japonica L., third and fourth boring 

 in stems of the same plants. 



Imago ^^) (pi. V, f. 1) measures about 9,5—11 mm in expanse 

 and somewhat ressembles some species of Gracilaria Haw., Coleo- 

 phora Hb., or, particularly, Metriotes H.-S. Irl repose it sits with the 

 fore part of the body slightly erected, the antennae lying on the dorsum 

 and the labial palpi ascending and diverging. The colour is yello- 

 wish gray, sprinkled with brownish, with some purplish or pink tint 

 on the fore wings. The markings on the latter represented by — 

 two brownish rounded dots, one on the middle of the median cell 

 RCD and another at the distal angle of it (cf. pi. VI, f. 8), — two or 

 three indistinct patches of scales lying on the base between veins R, 

 С and Ai (on „the fold"), and some small points along the termen 

 and apical portion of costa. Hind wings pale gray, somewhat shining. 

 Cilia of fore wing very long, especially on dorsum and except the basal

 into tlie study of Lepidoptera (K u s n e z о v, N. Introduction. Faune de la
