148 ENTOMOLOGICAL SOCIETY 
that the sub-tropical avifauna had precisely the same distribution 
which he had found for Coleoptera. 
Judge Johnson stated that the West Indian flora, so far as he 
had observed it, did not extend far into the interior of Florida, 
but extends north on the west coast as far as Tampa Bay. 
Dr. Marx reviewed the spiders collected by Mr. Schwarz, and 
finds that of the 26* species collected by him one only is tropi- 
cal, 7 are common throughout the United States, and iS'are like 
the usual Southern United States forms. In fact, this collection 
is peculiar for the large proportion of Northern forms. Centru- 
ms biaculeatus, a scorpion found by Mr. Schwarz, is found also 
in South America and Africa. 
Mr. Schwarz said that he estimated the number of semi-tropi- 
cal Coleoptera in Florida at from 250 to 300 species. He does 
not believe that the wind has much to do with the distribution, 
because it is prevailingly east and west at the seasons when the 
insects might possibly be carried there. 
Mr. Smith gave the characters and affinities of the genus Cy- 
dosia,* which he finds a true Arctiid* allied to Cerathosia. He 
also gave some notes on the habits of Lachnosterna, as observed 
by him, and stated that the species are unusually abundant this 
year. 
Dr. Marx showed the figure of an abnormal Scorpion, having 
only a single joint to the metatarsus ; also a figure of a Lycosa 
in which the middle row of eyes has disappeared. 
Mr. Howard showed two plates of genitalia drawings from 
Mr. Scudder's forthcoming work on the Butterflies of New Eng- 
land. 
Mr. Smith stated that he had looked over these with great in- 
terest ; he was well acquainted with the forms of these organs as 
found in the Macro-Heterocera, but had never carefully exam- 
ined the Rhopalocera. Some of the figures none were named 
bear a striking resemblance to the form usual in the Sphingidce. 
Mr. Howard read some interesting passages out of G. H. Six's 
translation of Snellen von Vollenhoven. 
Mr. Schwarz read the following note :
