ferae Fab.), and sweet potatoes from Cuba and Mexico contained 

 Cylas formicarius Fab., and shipments from Jamaica, the Bahama 

 and Madeira Islands were infested with Euscepes batatae Waterhouse. 

 Metamasius sericeus OHv. was intercepted in sugar cane from Cuba 

 found in ships' stores and in banana leaves in banana shipments from 

 Costa Rica. The pink bollworm (Pectinophera gossypiella Saund.) 

 was intercepted in cotton seed from England, Egypt, India, and on 

 twenty-three occasions in cars arriving from the interior of Mexico. 



Azaleas from. Japan, introduced in accordance with Regulation 14, 

 Quarantines?, were in a number of instances found to bear injured buds. 

 Repeated futile attempts were made to collect the insects responsible 

 for the hollowing out of the buds. Samples of the injured buds were 

 forwarded to Dr. vS. I. Kuwana who advised that it was the work of the 

 larvae of Earias rosifera Butler, which is reported to have two generations 

 a year, the adult moth of the first brood appearing in April or May, 

 and the second brood in July. The moth of the last brood deposits 

 its eggs near the flower buds, and the larvae infest the buds shortly 

 after hatching, and become full grown in September or October, hiber- 

 nating in the larval condition in cocoons in the soil or between decayed 

 leaves. In view of the fact that the exporting season in Japan is from 

 November to April, and that the insect is in the soil or in old leaves 

 at that time, and further that these plants are shipped absolutely free 

 from soil, it appears that there is little likelihood of introducing this pest. 



The Noctuid genus Earias contains some two dozen or more closely 

 allied and similar species, several of which are known to be of primary 

 economic importance; for example, E. insulana Boisduval, which is 

 •the well known Egyptian Cotton Bollworm, and is second only to the 

 Pink Bollworm in the amount of injury it occasions to cotton in that 

 country. E. chlorana Hubner is another injurious species feeding on 

 willow in Europe.
