GENERAL NOTES. 



SOME INJURIOUS GARDEN AND FIELD INSECTS IN TROPICAL NORTH 



AMERICA. 



Auoust 16, lUO.S, Mr. O. W. Barrett, entomologist of the Porto 

 Kico Experiment Station, sent specimens of noxious insects from that 

 country which are interesting because of their relation to species 

 known to occur also on the mainland of the United States. One of 

 these was an unknown species of Aphis, which is stated to seriously 

 affect squashes. A leaf -beetle, Cei'otonia denticornis 01., verv closely 

 related to the bean leaf-beetle of the United States [CWototna trJfur- 

 cata)^ was said to be injurious to cowpeas. A flea-beetle, Systena 

 hasalis Duv., was injurious to Russian sunflower; while a leaf -hopper, 

 AgaUla teneUa Ball., was stated to damage the leaves of beans, cow- 

 peas, and other plants. Later, September 30, 1903, Mr. Ed. Ferrer, 

 La Magdalena, Caj^ainas, Cuba, stated that Cerotoriut, denticornis did 

 a great deal of harm to cultivated l)eggar-weed {Meihoiiila sp.), which 

 also grew wild in that vicinity, from 30 to 50 per cent of the weight 

 of the leaves being a good estimate of what the beetle devoured. 



l)!<(hrotlca hidtecita^ another leaf-beetle related to the corn root- 

 worms was received from Mr. A. L. Herrera, Cit}^ of Mexico, Mexico, 

 with the statement made under date of December 3, 1902, that it was 

 injurious to wheat at Salvatierra, State of Guanajuato. During July, 

 1903, we received from Dr. Silvio Bonansea, of the City of Mexico, a 

 specimen of Scyjfhophorns acupimctatus Gyll., a Aveevil ({uite com- 

 monly occurring in southern California which our correspondent 

 stated was damaging henequen {Agaoe rlgida). A short account of 

 this species and a note on the occurrence of the larva in the interior 

 of the stems of Agave mexlmna has been given by Dr. Eug. Duges in 

 the Annales de la Societe Entomologiciue de Belgique, 1886, p. 33. 

 A short note on the occurrence of the adults on trunks of grape- 

 vine at Poway, Cal., M'herc they feed on sap, was also published, in 

 Volume V of Insect Life (p. 35). 



REMEDY FOR STORED (4RAIN INSECTS IN CUBA. 



Mr. Limeon Poveda, jr., ownin- of a ])reeding farm in the suburbs 

 of San Leandro, the municipal boundary of the Cuban town of Palma 

 Soriano, known also as San Juan, who is also engaged in the practical 

 study of agriculture, writes as follows in regard to the occurrence of 

 weevils in maize and the remedies to be used in combating them:
