764 EXPERIMENT STATION RECORD. [Vol.36 



plete life histories of the eight species have been worked out from egg to adult, 

 and a tabular summary is given of the average time in days and the maximum 

 and minimum periods for each stage of the beetles. 



It was found during the year that two distinct varieties of Ldchnostema 

 " grande " and of L. " media " occur on the island. It is said to be necessary to 

 fumigate the holds of the boats bringing cane from the Dominican Republic, 

 due to the fact that in that Republic the leaves of the cane are eaten by the 

 caterpillar of a butterfly (CaUsto archebates), which is a source of severe 

 injury to the plant.

 452; abs. in Rev. Appl. Ent., Ser. A, 4 (1916), No. 7, pp. 307, .W8).— While the 

 insecticidal value of the arsenical salts in general use in agriculture is pro- 

 portional to the amount of arsenic they contain, their order of toxicity is modi- 

 fied by the varying degree of solubility and the presence of a toxic metal or of 

 impurities. Their arrangement in order of toxicity and the percentage of
