The fungus Metarrhizium anisopliae, which attacks Oryctes rhinoceros, 

 L., in Samoa, was also found attacking larvae of Rhagium inquisitor, 

 and larvae and pupae of Ergatesfaber, on the island of St. Marguerite. 

 Persona] observations as well as those of other authors with regard to 

 the artificial transmission of the fungus are discussed. Under laboratory 

 conditions it is possible to infect many varied species with the disease 

 owing to the unnatural conditions which tend to predispose the host 

 to attack, but under natural surroundings the same hosts prove to be 

 more or less immune to the disease unless a particularly virulent form 

 of it is produced.

In reply to a recent note on the authorship of the genus Lachnus 

 [R.A.E., A, viii, 200] it is stated that this name has been incorrectly 

 ascribed to Ilhger. The first description of the genus was given 

 in 1835 by Burmeister, and he is therefore the author.

Moth {Laspeyresia tnolesta, Busck). — Qtrly. Bull. Virginia State

In Virginia there are four, or under favourable circumstances five, 

 broods of Cydia (Laspeyresia) molesta and, though at present this 

 pest has not yet appeared in the main orchard districts, the fact that 

 it feeds upon most fruit trees in a similar manner to the codhng moth, 

 C. pomonella, suggests that it may come to have a destructive status 

 equal to, and perhaps greater than, the latter insect. 



No satisfactory method for its control has been devised as yet. 

 Orchard spraying tests show that arsenical sprays are but slightly 

 efiective, since the larvae feed largely within twigs and fruit. Limited 

 experiments, suggested by the terminal-feeding habit of the larvae, 

 were conducted to determine the benefits derived from the clipping 

 and the destruction of infested twigs. Although economy would seem to 

 forbid the application of such a measure on an orchard scale, the results 

 have been sufficiently encouraging to emphasise the advisabihty of 

 further investigation along this line, especially with small blocks of
