XYLORYCTIDA. 
PTOCHORYCTIS ROSARIA, MEYR. (PLATE LXIII FIG, 1.) 
Ptochoryctis rosaria, Meyr., B. J., XVII, 740 (1907)('). 
This insect, which has hitherto only been kaown from Bhutan('), 
is a serious pest of apple at Shillong, the red larva eating into the bark 
of young twigs under cover of a silken gallery (Plate LXIII, fig. la). The 
angles formed between outgrowing twigs form a favourite place for attack 
by this larva, and considerable damage may be done by the stunting back of 
young growth. Larve were collected at Shillong in October 1919 and brought 
to Pusa, where no apple is available, and they were supplied with twigs of pear 
on which they fed up to the end of February 1920. One was found pupated 
on 5th March and emerged on 9th March. 
The larva (Plate LXIII, figs. 16, c) is about 12 mm. long and about 
2 mm. broad across the head and thoracic region, cylindrical, tapering posteriorly 
very slightly and gradually, brick-red, with chequered whitish dorsal markings ; 
head dark-brown or almost black, shiny ; prothorax wholly covered by a 
brown, somewhat glossy plate ; ninth and tenth abdominal segments darker, 
the latter with a large dark-brown somewhat glossy plate; tubercles dark- 
brown, shiny, with rather long white hairs ; trapezoidal tubercles large and 
round, making the larva look spotted ; spiracles small, rather oval, dark-brown, 
with a slit in the middle ; legs black, shiny ; five pairs of equally-developed 
rather short, pale yellow prolegs. 
Pupation took place under webbed-up frass on a twig. In nature it pro- 
bably occurs in the larval gallery. The pupa (Plate LXIII, fig. 1d) is about 9 
mm. long and 2°5 mm. across the thoracic region, cylindrical, slightly and 
gradually tapering posteriorly, dark brown ; anal segment blunt, with a pair of 
short spines on the dorsal surface and with a flattened wing-like projection on 
dorsal margin of anal extremity; anterior extremity of pupa rounded and 
with a roughened surface ; the dorsal side of thoracic region and anterior part 
of abdominal area has also a roughened surface. 
The moth (Plate LXIII, fig. le) is pure white, with a few antemarginal 
black dots on forewing. (Pusa. Insectary Cage-slip 1988.)
