13f) ENTOMOLOGICAL SOCIETY 
Remarks on the address were made by Dr. Riley, Mr. Schwarz, 
and Mr. Smith. The unanimous thanks of the Society were then 
tendered Mr. Howard for his excellent paper. 
FEBRUARY 2, 1888. 
Seven persons present. President Schwarz in the chair. 
Mr. R. Godeffroy was elected a member of the Society. 
Dr. Fox read a paper " On Certain Genera of the Lycosida" 
discussing more particularly the genera Dolomedes and Ocyale. 
Attention was called to the conflicting descriptions of the genera 
as given by the standard authors, and particularly to the fact that 
no mention is made by any of them of the relative heighth of the 
cephalic portion of the cephalothorax. A comparative table was 
given showing in what respects the authors differed and in what 
they agreed in their generic descriptions or characters used. 
Mr. Smith mentioned that, while there was but a single named 
Dolomedes in the Museum collection, there were probably some 
species in the lot collected for the National Museum by Prof. 
Underwood last summer. That Prof. Underwood's intention 
was, if possible, to cover the old Hentz collecting grounds in 
Georgia and Alabama, and to get material to identify the Hentz 
species with what success remains to be seen. 
In response to a question by Mr. Schwarz, Dr. Fox gave the 
geographical distribution of the genus, and of some species, show- 
ing a very extended range. This subject was briefly discussed by 
Messrs. Schwarz, Howard, and Fox. 
Mr. Howard asked whether, where a European genus was the're 
well marked^and constant, the definition should be enlarged to in- 
clude American forms which showed some one particular character 
not present in the European species. 
Mr. Schwarz replied affirmatively, and cited the differences in 
the genus Pterostichus as an example of what had been done in 
Coleoptera. Mr. Smith cited the Noctuid genus Perigrapha, 
the European species of which have pectinated antennae in the 
female, while in the American forms the antennae are simple ; the 
genus, however, being the same in other respects, the American
