the ground when it has become dry. In the case of the Qiicniis dilatata the 

 procedure is much the same except that the leaf appears to be ahnost 

 invariably cut lower down. 



The method of egg-laying was studied by Mr. F. Gleadow, Deputy 

 Director, Indian Forest School, Student V. Subramarian, and myself (for 

 the first time) in May 1901. 



A small grub hatches from the egg and feeds on the decaying tissues, 

 becoming full-grown within ten days to a fortnight. The grub then leaves 

 the roll, which will by now have reached the forest floor, and pupates in the 



soi 



The insects oviposit during a period of three weeks in May, but the 

 number of eggs laid by each female has yet to be ascertained. 



Throughout Jaunsar-Barwar and the adjacent Native States of Tehri 



Garhwal, Jubal, and Balsan, this insect was very plentiful 



Relations to the j^^ ^^^^ ^^^^ ^^^^.^ -pj^g peculiar method of laying its eggs 



Forest. adopted by the insect results in the trees attacked being 



very heavily defoliated when the weevil is numerous. Trees of all ages are 



infested and it is the newly unfolded leaves which are primarily treated 



in this manner, the older ones being only resorted to after the newer ones 



have been all occupied. Fig. 2S1, b, shows a portion of a branch with the 



upper leaves defoliated by this insect. 



Methods of protection will be the same as those given below for the 

 sissu Apodcnis. 



Apoderus sissu, Marshall, sp. nov. 



KEKEKEN-CES.-Marshall, Ann. Mag. Nat. Hist. Feb. 1913; Stebbing, Depart. Notes, i, 33 ("jo^). 



Habitat.— Sutlej Valley, Kulu and Bashahr States, 2,300 ft. to 3,500 ft. ; 

 Changa Manga, Punjab ; Kumaun Terai Forests. 



Tree Attacked.— Sissu {Dalbcri^ia sissoo). Sutlej \'alley ; Changa Manga; 

 Chor Galia, Kumaun Terai. 



Beetle —The female beetle is similar in colouring to the male, but is larger, being about 



a quarter of an inch in length, while the male is one-sixth of an mch. The general colour 



throughout the insect is a bright golden yellow. Head, thorax, and 



Description. elytra are edged with black except at the outer upper edges of the 



elytra, where they are golden yellow. Snout and eyes are black. 



Intennae vellou at the base and furnished with black knobbed ends. Forehead between the 



eves blick' Klytra channelled, and they have three Ijlack patches situated triangularly on their 



upper halves, the patch at the apex being at the anterior end ; the elytra are edged with black 



on their inner margins, and the anterior outer corner of each bears a light brown spot ; they 



do not completely join at their bases, leaving several body segments exposed. Under-surface 



of the prothc.rax between the coxae a darker yellow-brown. Legs bright golden yellow.
