were observed on the weeds and grasses in and about the ponds. 

 The adults are of a straw color and have a green abdomen. The 

 adults were kindly determined by Mr. Banks. 



No eggs were obtained in spite of the many efforts. On ac 

 count of regular work it was found impossible to further trace 

 the life history of the insect. 



Mr. Ashmead asked Mr. Simpson if the larva have an organ 

 of attachment, and mentioned a larva of the neuropterous genus 

 Raphidia from Oregon, received alive at the National Museum. 

 It attached itself very tenaciously to the desk by a suctorial disk 

 on the end of the abdomen. He called attention to a figure of a 

 Raphidid larva published in the Cambridge Natural History. 

 Referring to the trichopterous larva, Mr. Simpson said he had 

 never noted such an organ in trichopterous Iarva3.

 In the absence of the President, the meeting was called to order

Under the heading Short Notes, Dr. Stiles called the attention 

 of the Society to a paper in a recent medical publication* in 

 which the author described experiments tending strongly toward 

 proof of the transmission of dengue or break-bone fever by spe 

 cies of the genus Culex. This note was discussed by Dr. How 

 ard. 



Dr. Howard mentioned the fact that had recently been 

 brought to his attention that the Cuban Anopheles argyritarsis 

 Desvoidy breeds at times in water retained in impressions made 

 by the feet of cattle. This observation, tnough not unique, is as 

 yet unpublished, and has an important bearing upon the possibil 

 ity of the destruction of malaria-bearing mosquitoes. 



Dr. Stiles asked the opinion of the Society in the matter of
