Summary. 



During the last years 1910 — 1914 in the tea plantations of the De- 

 partment of Apanages at Tshakva, near Batum, Transcaucasia, some 

 observations were made on a little Tineid moth attacking the tea bush. 

 The insect should be called „tea moth", its scientific name and position 

 being established in the following paper by Mr. N. J. К u s n e z о v, cus- 

 todian of Lepidoptera in the Zoological Museum of the Academy of 

 Sciences, who named the moth Paratnetriotes theae, new genus and new 

 species belonging to the subfamily Coleophorini. (Gf. Rev. Russe d'Ent. 

 XV, 1915, pp. 627—650). 



The adult and medium-sized larvae of the tea moth hibernate in 

 the interior of the terminal shoots of the bush (pi. IV, f. II, 2), which, 

 drying later up in the attacked part, become very conspicuous by 

 their shrivelled dried leaves (pi. IV, f. II). The smaller larvae of the 

 earlier stages do not leave the places of their initial development 

 in the mines of the leaves (pi. IV, ff. I, II, 1). These latter larvae, 

 somewhat retarded in their metamorphosis, migrate, during the second 

 half of March, into the fresh stalks of the new shoots of first plucking, 

 and make them wither and dry up during the second half of April. 



The larvae pupate (pi. IV, f. Ill, 1) in the interior of the bran- 

 ches, where they have lived, the pupation beginning from the end of 

 May and lasting till the end of July. The moth emerges through the 

 rounded holes (pi. IV, f. Ill, 2), about 2 mm in diameter, gnawed out 

 previously by the larva and spun around with a white web. The moth 

 flies in June till August. Among other plants than the tea bush {Thea 

 sinensis Sims.) the larvae were observed on the Camélias {С. japo- 

 nica Linn.) only. The writer believes the moth being not indigenous 

 but imported from China. 



The insect increasing already in great numbers requires some 

 measures of control.' The writer's recommendations are — immediate 

 burning of the twigs and shoots cut during the common winter pru- 

 ning of the bush, and as a complementary measure — cutting and bur- 

 ning of attacked twigs and shoots during the beginning of April.
