Johnson spoke of his studies of some Diptera as follows: The results of 

 mv recent study of the genus Stratiomyia may be summarized as follows: 

 the number of species in Osten Sacken's catalogue recorded north of 

 Mexico is twenty-nine; to this number Bigot has since added six, a total 

 of thirty-five. Of these fourteen have been reduced to synonymy, six 

 remain unidentified, one has been referred to a new genus, and two new 

 species have been described. This leaves for our consideration sixteen 

 species; these are divided into three groups, the first Stratiomyia, s. str., 

 contains five species; the second, Thereodonta, two; and the third, Nor- 

 mula, nine. The color pattern is still largely used in distinguishing spe- 

 cies, but in almost every case the male and female have both been studied. 

 Dr. Horn stated that his paper on Scynmus was nearly completed, and 

 that he hoped to present it at the next meeting. Mr. Calvert quoted from 

 Dr. Riley's presidential address to the Ent. Society of Washington of 

 February, 1894, that no species of Odonata habitually hibernated, and 

 stated that Sympycna fusca has been found to regularly pass the Winter 

 in the imago state, in numbers, in France.

I find that the life-history of this Sphinx has not been written. 

 The larvae occurred commonly on morning-glory vines near 

 Honolulu, Hawaiian Islands.
