438 FAMILY CURCULIONIDAE 



C. brandisi in the Finns longifolia. In view of the fact that this latter 

 weevil is a pest of the first magnitude, the life history of this blue-pine and 

 spruce insect, as also its abundance, requires to be carefully ascertained. 



Cryptorhynchus sp.* 



Habitat. Tharrawaddy, Lower Burma ; Katha, Upper Burma. 

 Tree Attacked. Teak (Tectona grandis). Kadin Bilin Forest, Tharra- 

 waddy ; Katha. 



Beetle. Black, of usual cryptorhynchid shape, the elytra with prominent longitudinal 

 striae down them, and punctate. Length, 13 mm. 



Larva. Whitish yellow, curved, corrugated, with a yellow-brown head. Specimen taken 

 was half-grown. 



Towards the end of January 1905 whilst in Tharrawaddy I cut out a 

 specimen of this weevil from its pupal chamber in the 



Life History. sapwood and bark of a teak-tree which had been felled 

 in the thinnings made the previous year in the 1888 



plantation. The beetle lays the eggs in the bark. The grub on 

 hatching feeds at first in the bark and bast, and then in the sapwood, 

 eating out the usual irregular winding gallery. When full-grown it gnaws a 

 hole through the bark to the outside, plugs it up with a fibrous mass of bark 

 and wood shavings, and then pupates beneath this. The specimen of the 

 beetle found was taken in this position. It was fully mature, and hiber- 

 nating until the approach of the hot season. I also found one half-grown 

 grub in a gallery in the tree. 



I obtained mature living beetles from pupal chambers in the wood of 

 the roots of a large girdled teak-tree on 20 February 1905 in the Mohnyin 

 Forest in Katha. This tree had been girdled about a year before. The 

 beetles appeared to be ready to fly. It is practically certain that the insect 

 passes through several life-cycles in the year, but the number has yet to be 

 ascertained. 



In view of the importance of this genus to the forester it is interesting 

 to know that there are species which infest the teak. 



Cryptorhynchus ? sp. 

 Habitat. Changa Manga, Punjab. 



Tree Attacked. Sissu (Dalbergia sissoo). Changa Manga Plantation, 

 Punjab. 



Beetle. Small. Head and prothorax dark velvety brown or black, covered with a short 

 golden pubescence ; elytra chestnut-brown, darker towards apices, with a golden pubescence. 

 Legs brown. Length, 6 mm. to 8 mm. 



Specimens of this weevil were taken from beneath the rotten bark of 

 the main roots of a large standing green sissu-tree in the Changa Manga 



: I have since determined this insect to be identical with Cryptorhyncits brandisi;
