SCIENTIFIC COMMITTEE. 



W. T. Thiselton Dyee. Esq.. F.R.S.. C.M.G.. hi the Chair, and 

 eleven members present. 



Mealy-bug at Alexandria. — Mr. Morris supplemented the 

 information already given by him respecting this new Egyptian 

 pest, by reading a letter from Mr. J. W. Douglas, to whom the 

 specimens had been sent, stating that the coccids had proved to 

 be not only a new species but a new genus. It was proposed to 

 describe them under the name of Crossotosoma argyptiacmn. 



Growth on Stem of Cattleya. — Mr. McLachlan reported on 

 a peculiar growth on the stem of a Cattleya from Brazil. This 

 was at first supposed to be of the nature of a cocoon, but a careful 

 examination of the structure had shown it to be a gall. Professor 

 Marshall Ward undertook to make further examination. 



Sugar-cane Borer at St. Vincent. — Mr. McLachlan drew 

 attention to a disease in Sugar-cane at St. Vincent, where hi 

 some localities about 25 per cent, of the crop would be lost this 

 year. According to Mr. Herbert Smith, who had examined the 

 canes, a beetle of the family Scolytida?, and the larva of a moth, 

 were concerned. It is probable that the beetles only enter the 

 canes by the exit holes of the moths. The moth is probably a 

 widely spread species, already known to attack Sugar-cane in 

 other countries. The affected canes should be burned, and steps 

 taken to destroy the moth in the localities specially frequented 

 by it. 



Disease of Orchids. — Mr. Morris exhibited several specimens 

 of a Cattleya attacked by a fungoid disease of apparently a very 

 virulent character. From a specimen received about a fortnight 

 ago, Mr. Massee had infected at Eew two or three healthy 

 plants, and in three days the whole of the pseudo-bulbs had 

 become diseased. Specimens of similarly affected plants were 

 sent by Mr. James Douglas, from a gardener who was anxious 

 to know if there was any remedy, as he feared his collection was 

 in danger of being destroyed. The Committee was of opinion
