at Felicite Island ; wet weather towards the end of the year con- 

 siderably reduced its numbers. The Cerambycid, Macrotoma wrighii, 

 was taken from a cedar tree on Praslin, where it has developed to such 

 an extent as to have become a pest. Stromatium barbatum, ¥., another 

 beetle of the same family, has been found attacking furniture. The 

 larvae bore into all sorts of wood, including rose-wood, teak, etc. 



Many Coccids occurred, including Aspidiotus trilobitiformis on 

 Passijlora foetida and Anacardium occidentale ; Pulvinaria antigoni 

 and Asterolecanium pustulans var. scycheUaruin on Lantana ; 

 Pinnaspis buxi, Bch., P. buxi var. alba, Ckll., and Poliaspis sp. on 

 leaves of areca nut palm {Areca catechu) ; and Ceroplastes rubens, 

 Mask., on Aci'ostichum aureum.

Attention is drawn to the occurrence of the larch sawdfly, 

 Lygaeonematus ivesmaeU, Tischb., on young larch trees in Yorkshire. 

 It has so far only been recorded from Germany and Holland where it 

 is considered a rare species.

This list includes the Histerid, Lioderma quadridentatum, F., 

 predaceous on other insects, especially the larvae of the sugar-cane 

 borer, Diatraea saccharalis, F. ; the Coccinellids, Megilla macidata, 

 De G., predaceous on larvae of Laphygma frugiperda, S. & A. (rice- 

 caterpillar) ; Hyperaspis f estiva, Muls., on Pseudococcus sacckari, Ckll., 

 which is also attacked by ^. octopustulata, F., and //. trilineata, Muls. ; 

 Azya trinitatis, Mshl., and Neda dilychnis, Muls., on Aspidiotus 

 destructor, Sign. ; A. pontbrianti, Muls., on Saissetia hemisphaerica, 

 Targ. ; Cryptognatha nodiceps, Mshl., on Aspidiotus destructor, Sign., 

 and the early stages of Aleurodicus cocois, Curt. ; and Pentilia 

 insidiosa, Muls., on Asterolecanium bambusae, Bdv., and Pseiulococcus 

 citri, Risso. 



The Dynastid beetle, Strategus aloeus, F., is a pest of young coconut 

 palms. The adults bore into the soil near the root, which they 

 gradually destroy, and also attack the heart of the palm itself. The 

 larvae are found in small colonies in decaying stmnps of trees. Ligyrus 

 ebenus, De G., is occasionally found in stems of full-grown sugar-cane. 

 Dyscinetus bidentatus, Burm., of which the adult beetles bore into 

 the stems of sugar cane is a serious pest. As many as 38,000 beetles 

 have been collected by one gang on one estate in a single year. The 

 life-history occupies about 100 days. The eggs are laid in the earth 

 at a depth of about 2 to 5 or 6 inches, near the cane stools. The 

 duration of the larval stage is not known, but probably covers several 

 months.
