proceedings: entomological society 299 



Mr. C. W. Collins, Gipsy Moth Laboratory, Mehose Highlands, 

 Massachusetts; and Mr. Howard L. Clark, North Farm, Bristol, 

 Rhode Island. 



The regular program was as follows: 



Harold ^Morrison: Notes on the Virgin Islands. Mv. Morrison dis- 

 cussed briefly the size, location, past history, and the economic devel- 

 opment of the islands, giving some notes on the principal agricultural 

 crops and their chief insect enemies. Among the insects mentioned 

 were termites, the different varieties of a species of weevil (Diaprepes 

 sp.) the cotton-leaf blister mite, and the sweet-potato weevil (Euscepes 

 batata). About thirty species of scale insects were collected, and about 

 twenty-six hundred specimens representing other orders. No fruit 

 flies were found, and fruit was very scarce on the islands due to the great 

 destruction caused by the recent hurricane. Mr. Morrison's communi- 

 cation was di'scussed by Messrs. Schwarz, Casey, Busck, and Pierce. 



R. E. Snodgrass: The value of pictorial charts in extension entomology. 

 This paper was illustrated by a number of artistically drawn charts 

 designed to illustrate the life histories of economic insects. The speaker 

 presented a strong argument in favor of this manner of carrying ento- 

 mological information to the general public. He stated that the charts 

 would attract and hold attention, that they were designed to bring out 

 the most vuhierable points in the life-histories of the insects illustrated ; 

 and that they were quickly and easily read. He believed that the 

 essential points in control would be more readily grasped by the reader 

 than from the written page. In discussing Mr. Snodgrass' remarks 

 Dr. L. O. Howard pointed out some of the excellencies of the charts 

 from the artistic standpoint. .
