648 I'ROCEEDiyGS OF THE THIRD ENTOMOLOGICAL MEETING 



legs, and wing-fringes, yellow. The forewings are orange-yellow at the 

 apex and near the posterior angle, the apex bearing two black spots 

 which are sometimes one or three in the female : the hind wings are 

 orange-yellow at the rather broad outer-margin : antennae, legs, head, 

 and anal tuft are orange-yellow or yellow or sometimes yellowish white. 

 In the darker form the forewings bear two black spots at the apex and 

 are blackish at the middle of the ciUa, 



The female is almost always fertilized by the male only one day 

 after emergence, and in three or four or sometimes seven days it usually 

 begins to deposit its eggs on the under-side of the matured leaf in a 

 mass which contains 15 — 145 eggs, covered by yellowish hairs from the 

 anal tuft. The eggs usually hatch in about ten days after deposition 

 in April or May, and the newly-hatched caterpillars live together near 

 that place and never move from place to place until the first moult. 



The whole life-cycle occupies about 55 days, according to only one 

 breeding in our laboratory in Taihoku. This insect is mostly attached 

 to the tea bush ; it is, however, found feeding on orange and Eriobotrya 

 japonica sometimes, but its injuries to these are very slight. The tea- 

 farmers generally fear this creature more than some other serious pests 

 of the tea-plant. 



Up to the present time nothing has been done but to collect and 

 kill the caterpillars or eggs. It is, however, very dangerous to do it, 

 as the poison of the hairs is rather strong for the skin, and the natives 

 very often suffer from the hairs of the caterpillars. At one time, I 

 used several contact poisons for the caterpillars and this gave rather 

 good effects, but further trials are desirable. 



No. 28. — Euproctis varians, Walk. {Hoshi-ki-DoJcuga.) 



This has been first mis-identified by the author as E.jlavinata, Walk., 

 and I now correct the nomenclature as above. 



Although this species is found throughout the island of Formosa, 

 it is a rather rare Lymantriad there, and it attacks the leaf of orange 

 and tea, but its mjuries are slight. 



The larva is black, with a reddish-yellow lateral stripe just below 

 the stigmata and with a narrow similar coloured dorsal stripe which 

 appears only on the thoracic portion and suddenly widens on the first 

 thoracic somite ; all these stripes have not straight margins but are 

 irregularly and slightly notched ; on each somite there are four oblique 

 narrow reddish-yellow flecks, two on the dorsum in \/ -shape, and 

 another two on the side from the lateral stripe near the anterior margin,
