Ordert Coleoptera. Family, Scolytidcs. 

 (Plate IV. figs. 2, 2a, 2b, 2c, 2d.) 



Beetle. — A minute little beetle brown in colour and |th inch in 

 length. The antenna is angled and ends in an ovate club. There is 

 no rasp-like surface to the front of the thorax. The elytra da not 

 quite cover the abdomen, the latter being turned upwards beneath. 

 The elytra have parallel row s of pits upon them. Fig. 2 show r s a 

 dorsal and 2a, a side view of this insect, enlarged. Figs. 2b and 2C 

 the antenna and leg enlarged. Fig. 2d the larva enlarged. 



Larva. — Small elongate white with a brownish head and no legs. 

 This beetle only attacks the green shoots of the mango and bores 

 into and lays its eggs in the green layer beneath the outer bark of 

 the twigs and the sapwood. Its presence can be readily detected 

 owing to the fact that black patches appear upon the green cortex. 

 Above these black patches the leaves on the twig will be seen to be 

 turning yellow and they die and fall off. 



Thefbeetles appeared to be just maturing and some larvae were 

 found in the twigs on May nth. This was probably the first genera- 

 tion of the year, and it is probable that there are one or two more 

 subsequent ones. 



No further notes appear to have been recorded upon this insect, 

 which is new to the British and Indian Museum collections. 



It was found in the same trees as the D. distinctus above des- 

 cribed, and the remedial measures advocated for the latter apply 

 equally to the scblytid. This latter, however, will never be found 

 attacking dead branches. 



Points in the life-history requiring further observation. 



1. When are the eggs of the first generation laid, i.e., when are 



the beetles first found attacking the trees in the spring ? 



2. The number of generations in the year. 



3. The number of eggs laid by the ? beetle. 



4. Hypomeces sp. 



Order, Cdecptera. Family, Curculionida. 



A fairly large stout black weevil. Head with a broad blunt snout, 

 channelled and with a longitudinal median channel running down 

 it dorsally and some scattered white hairs anteriorly. Eyes prominent, 

 black, placed rather far back on either side. Prothorax triangular, 

 truncate, twice as wide behind as in front, corrugated, with a longi- 

 tudinal median dorsal channel on the anterior half. The thorax is
