is probably the quickest and safest method of dealing with the pest. 

 We must, however, take care for the season of the tea-plant. There 

 is a Tachinid fly reared from the pupa of the female. 



No. 23. — MaJiasma sp. (Kuro-Minoga.) 

 It has been quite recently noticed by us that this Basket-worm is a 

 rather common insect injurious to tea bushes in the several districts of 

 Toyen-Cho. 



The caterpillar commences its career, after emerging from the egg, 

 by covering itself with a few minute pieces of tea leaf, attached by one 

 end to the leaf. They are at first conical little houses standing on a 

 flattened base and not more than 6 mm. in size. At this stage they 

 are very dangerous and spread all over the bushes in such numbers 

 that they may be said ultimately to ruin the entire foliage of a bush, 

 and then take to back. As they grow larger they seem to be less voraci- 

 ous, and the bulk of them disappear by some means or other. The full- 

 grown case is about 40 mm. long and nearly 20 mm. broad, and is 

 clothed with tea leaves each united by its lower extremity, the upper 

 and lower ends being free and spreading outwards from the bag. The 

 full-grown larva is similar to that of the preceding Clania, but it is 

 rather paler, and the yellowish stripes on the thorax are rather broad but 

 the middle one is somewhat inconspicuous ; the abdomen bears about 

 ten tubercles, which are not much darker than the colour of the body, 

 on each segment : the legs are paler ; the length is about 23 mm. 

 The pupa of the male is castaneous brown : the wing-sheaths are siort 

 and extend to near the posterior margin of the ventral abdominal seg- 

 ment ; the second and fifth segments each bears a row of minute spines 

 which are anteriorly directed at the posterior margin, and on the third 

 and fourth segments there is a row of minute rather inconspicuous 

 tubercles on each dorsum near the posterior' margin, while each of the 

 seventh and eighth segments bears a row of rather conspicuous hind- 

 wardly-directed spines at the anterior margin ; the anterior two-thirds 

 of each abdominal segment is finely transversely striolate ; the apical 

 segment is curved below, and bears two sharp distinct spines directed 

 below, and just before their bases there are two very short triangular 

 processes. The length is about 11 — 13 mm. The female pupa is not 

 known. 



The male moth has uniformly dark brown head, thorax, abdomen, 

 and forewings ; the autenuEe bear rather long branches decreasing to- 

 wards the tip ; the forewing has 12 veins, but the hindwing has 8 veins ; 

 the veinlet in the discal cell is forked but in the forewing this is not 

 conspicuous. The fore tibia bears a very long spine. The expanse
