mosquitoes (Janthinosoma) with clusters of eggs of Dermatobia 

 attached beneath the wings. It would appear, then, that the eggs 

 hatch and the larvae are transferred to the host, while the mosquito 

 sucks blood. As to the manner in which the eggs are attached to 

 the mosquito, Surcouf accepts the explanation of Gonzales- 

 Rincones of Venezuela, who had transmitted the specimens. The 

 latter is credited with a statement that the eggs, along with a vis- 

 cous substance, are deposited upon the foliage and that they become 

 attached to the mosquito accidentally as it walks over the leaf. 

 This explanation, the speaker said, he could not accept. The 

 eggs were found attached to a part of the mosquito's body which 

 does not come near the leaf surface when the mosquito rests upon 

 it ; also the eggs are attached in a definite way by their bases and 

 with the hatching end outward, and this could hardly be accom- 

 plished accidentally. Furthermore, under the circumstances 

 assumed, the eggs for the most part would be picked up by other 

 insects, which would not bring about their transfer to a suitable 

 host. There is no reason to doubt that the eggs discussed by Sur- 

 couf are really those of Dermatobia, and his statement shows that 

 these eggs have been repeatedly found attached to mosquitoes. 

 Remarkable it is that in every case the mosquito appears to have 

 been a Janthinosoma. Prof. Urich, of Trinidad, has called Mr. 

 Knab's attention to the fact that he has also found Janthinosoma 

 with the eggs attached, and that in 1905 he sent such a specimen 

 to the Bureau of Entomology, but that he received no satisfactory 

 explanation. 



-Dr. Martini gave a short address, thanking Dr. Howard and 

 other members of the society for the help they had given him. He 

 stated that before leaving Hamburg, he had been informed that 

 he would be able to obtain much assistance while here, but he 

 found upon his arrival even more help than he had anticipated. 



Dr. Howard gave a brief account of his western trip in com- 

 pany with Dr. Marchal, mentioning a few incidents that occurred 

 during the journey. 



Mr. Schwarz spoke of the occurrence of Psylla buxi Linn. 

 He said he had observed this insect in great numbers at Atlantic 

 City many years ago. Mr. Banks said that he had taken this 

 Insect two or three years before in New York City on box hedge.
