Lugger described more fully the way in which the parasite was 
attached to the spider. Dr. Marx described the ways in which 
spiders molt, and Dr. Fox detailed the circumstances under which 
the specimen was found.

OBSERVATIONS UPON THE HETEROPTERA COLLECTED IN SOUTHERN 
FLORIDA BY MR. E. A. SCHWARZ. 
BY P. R. UHLER. 
Through the kindness of Mr. Otto Heidemann I have been permitted to 
examine the interesting collection of Hemiptera made in the extreme south- 
ern part of Florida by that ardent student and acute collector of Coleoptera, 
Mr. E. A. Schwarz. 
This collection throws much additional light upon the insect fauna of that 
peculiar portion of our southern territory, and enables us to perceive with 
greater distinctness the West Indian and Neotropical characteristics of that 
country. South of Indian River, more particularly, the types of this fauna 
appear, and upon the border land most influenced by heat and moisture 
they form a decidedly distinct feature of the insect assemblage. Genera 
such as Diolcus, Loxa, Vulsirea, Edessa, Spartoccra, Ca tor hint ha, Hy- 
alymenus, Pthia, Jadera, Lasiochila, Zeltis, and Mononyx are here repre- 
sented by conspicuous examples, and species of other genera which are 
common in San Domingo, Cuba. Mexico, and Central America are not 
less numerous in this region. 
Certain Nearctic and widely distributed genera, such as Homcemus, Pan- 
gceus, Euschistus, Mormidea, CEdancala, Ligyrocoris, Emblethis, Nys'ius, 
Pygolampis, Aradtis, Aneurus, Galgulus, etc., are also present in the or- 
dinary numbers, and show that the North American continental forms of 
Hemiptera, although having had the usual struggle with widely varying 
climatic conditions, have been able to hold their place in spite of compe- 
tition with the new comers from more southern lands. From the abun- 
dance, variety, and instability of the assemblage of species now known to 
inhabit the region extending from Central America to Southern Colorado, 
we are induced to believe that the principal part 9f our United States 
Hemipterous fauna has been derived from that quarter. Nearly all the 
genera and species, excepting only the high-mountain and cold weather 
forms, thus far found in the country between the Great Lakes of Canada 
and the alluvial belt south of Tennessee occur quite abundantly in Mexico 
and the adjoining countries. 
The time at the disposal of Mr. Schwarz was too short to allow full col- 
lections of the species of this region to be secured ; but the 95 species which 
were taken, together with those brought together by the industry of former 
collectors, enable a fairly correct estimate to be made of the character and 
peculiarities of the Hemipterous fauna of the region. A singular absence 
of Capsidce is to be noticed in this collection, and there are also no speci-
