tead, with two distinct rather large longitudinal blackish brown dorsal 

 stripes which are far apart from one another on the anterior border, 

 and wdth many minute blackish brown dots especially on the side r 

 second and third somites blackish brown, with three narrow yellowish 

 longitudinal stripes on the dorsum. The abdomen bears 18 bro\?n 

 tubercles on each somite, and from each of these tubercles a fine hair 

 springs out : the anal somite is blackish brown. The legs are blackish, 

 bearing a strong dark castaneous claw on each one, while the prolegs 

 are very short and brownish. The full-grown larva measures about 

 25 — 35 mm. in length. The larva lives in the case formed of longi- 

 tudinally arranged twigs and a few small pieces of leaves, these twigs 

 being about 2 — 27 mm. long. The effect of its attack on the bush is 

 very similar to that of the Variegated Bag-worm, destroying com- 

 pletely every leaf of that and of the next one or two bushes. After 

 it is full-grown, the larva turns to a blackish brown (or brownish in the 

 female) pupa which has a shght purphsh tinge, inside the case. Before 

 pupation the larva firmly fastens the case to a twig at its anal end, and 

 the pupa always rests head downwards. The pupa of the male is slender, 

 with short wing-sheaths which extend below to the posterior margin 

 of the third abdominal segment ; each dorsal segment of the abdomen, 

 from the fourth to the eighth bears a row of many minute blackish 

 spines near the anterior margin, behind that the surface is usually 

 transversely wTinkled except the narrow posterior border ; the anal 

 segment is slightly curved below and bears two short but stout down- 

 ward-directed sjpines belov/ the anal extremity. The pupa is about 

 11 — 13 mm. long. In the female it is much larger but much paler, 

 and is spindle-shaped ; the abdomen bears a row of 5 — 13 minute less 

 conspicuous roundish tubercles on the dorsum of each segment 

 (from the fourth to the eighth), and behind that the side is very finely 

 transversely striolate leaving the rather broad posterior border ; the 

 anal segment bears two spines quite similar to those in the male. The 

 length is about 16 mm. 



The male moth is commonly found in March and April in the district 

 of Taihoku-Cho, but it can be found nearly throughout the whole year 

 from the North to the South. Owing to the fact that the larva forms 

 its case with many twigs, it is almost always more injurious to the tea 

 bush than is the preceding Clania. 



The remedy for this insect is to pluck off the cases and destroy them 

 during the winter time, but this is sometimes very heavy work in the 

 case of a bad attack. In such a case the whole affected bushes are 

 cut-off near the soil-surface and the cut-off portions are burnt. When 

 only a few plants are badly attacked, get dry straw and fire them. This
