22'J PROCEEDINGS OF THE THIRD EXTOilOLOGICAL MEETING 



[Ploccederus pedestris, WTiite. 

 Gahan, F. I. C'eramb. p. 123. 



Ploccederus pedestris is found boring into mango trees in Dacca. Last 

 year in February grubs, pupae and beetles were found in numbers in a 

 dead tree. As regards its habits, the grub feeds on the portion between 

 the bark and the wood and goes upwards or downwards. M'hen full- 

 grown, it makes a big slanting hole in the wood and pupates in a yellowish- 

 white hard cocoon inside the hole. The life-history has not been studied 

 in detail. 



We have P. pedestris from Pusa, but it is not common here and it 

 is not recorded from anywhere East of this by Gahan. The Dacca 

 species is more hkely to be P. obesus, Gahan, but it is impossible to say 

 without seeing the specimens.] 



^olesthes holosericea, Fb. 



Gahan, F. I. Ceramb., pp. 127-128 ; Stebbing, Ind. For. Ins. 

 Col., pp. 301-305, S. 208-210, t. 19. 

 Gahan gives the distribution as North-West India, Bombay, 

 Nilgiris, Ceylon. Assam. Tenasserim, Andamans. Nicobars, Siam and 

 Malay Peninsula. 



We have it from Khedut (Baroda) [labelled Poona on specimen] 

 reared from a larva in guava stem, the adult emerging on 4th April 1907. 

 This stem was also infected with Belionota prasma, and it is doubtful 

 how far M. holosericea is a pest of living trees so far as non-forest trees 

 are concerned. 



? Rhylidodera robusta. 

 Gahan, F. I. Ceramb., p. 147, f, 59. 

 This was reared by K. D. Shroff on 4th April 19CS from a larva boring 

 Ficus carica at Mandalay, and has also been noted at Thaton in mango. 

 The identific.ition of this species is uncertain. 



CJdoridolvm cdcinene, Thorns. 



Gahan, F. I. Ceramb., pp. 199-200 ; S. Ind. Ins, p. 323, f. 177 ; 

 Proc. Second Entl. Meeting, p. 211. 

 We have specimens from Pollibetta and Virajpet, in South Coorg. 

 This insect occurs in the orange-growing tracts in the South Indian Hills 

 and does serious damage to Citrus trees by its larva boring in the stems 

 and large branches. It seems to be rather sporadic in its appearance, 

 and has only been noted as a pest in Coorg.
