As regands such technical work as eoiicerns the identifica- 

 tion if insect pests and plant diseases, all that work is referr- 

 ed to the Estaxiion Agronomica at Santiago de las Vegas, to 

 which it properly belongs. At present it haippens that the En- 

 tomologist and the Pathologist of the Estacion are hoth memhers 

 of the 'Commission. The Commission as such is not supposed to 

 attend to technical details of this nature. There is, however, an 

 important work along this line that should he treated. !The Com- 

 mission of Plant Sanitation is authorized to issue certificates 

 of inspection for plants to be exported to other countries. In or- 

 der to do this efficiently the members of the Commission or the 

 Inspectors must be acquainted with the Tarious insects and 

 diseases of the Island; the better acquainted they are with these 

 pests, the more efficient they may become as inspectors. It hap- 

 pens, however, that there is no complete list or description of 

 all the known insects and diseases of Cuba, and mereover there 

 are many insect pests that are not known, and many plant 

 diseases the cause of which is not known. Thus the Commission 

 is severely handicapped in the beginimg on account of these con- 

 ditions. In order to present to the public the actual situation as 

 regards this matter the Commission has compiled a list of all the 

 known insects aiad the undetermined pests, the plant idiseases 

 whose cause is known, and those the cause of which is not yet 

 known. The actual data available from publications in Cuba is 

 undoubtedly far from complete, a fact much to be regretted. It 

 is believed, however, that a publication of these lists will serve 

 to call attention to this situation and therefore bring aid to its 

 improvement. Following is the list :
