OF WASHINGTON. 147 
two distinct faunas, and showed how by a series of deserts, moun- 
tain chains and wedge-shaped valleys the Coleopterous fauna of 
the two countries was well separated. 
Prof. Riley thinks that Mr. Schwarz omits an important factor 
in distribution, viz., the wind. He cited a number of species 
picked up far from land, and evidently carried by the wind. As 
a curiosity in distribution he cited the case of Hornia minutipen- 
nis, which he received from Fresno Co., Cal., living with an 
undescribed species of Anthophora. 
Dr. Horn has no idea how this species could become so wide- 
spread unless it followed the distribution of a particular bee. 
Prof. Riley thinks this the remnant of an ancient type, which 
by reason of its parasitic habits has undergone little or no change. 
Mr. Schwarz said this is the only Meloid occurring on both 
sides of the Continent. 
MAY 3, 1888. 
Eleven members present. President Schwarz in the chair. 
Mr. Tyler Townsend was elected Corresponding Secretary of 
the Society, vice Mr. O. Lugger, resigned. 
The discussion of Mr. Schwarz's paper was then in order, and 
the Secretary read the preceding abstract to inform members. 
Mr. Mann thinks that Mr. Schwarz's proposed restrictions to 
the admission of this fauna into our lists good and necessary. 
Dr. Fox thinks that the rule as to spiders would be too strict, 
and suggests that it may be necessary to make special rules for 
each order. 
Mr. Smith gave a review of some portions of the Lepidopterous 
fauna of this region, which in general is limited much as described 
by Mr. Schwarz for Coleoptera. A few of the species have 
spread into Northern Florida, and Southern Georgia. Unfortu- 
natelv the fauna is not so well known in the Lepidoptera, and many 
of the species from Florida have no definite locality. As a whole, 
he agrees thoroughly with Mr. Schwarz in his ideas. 
Mr. Schwarz said he omitted from his remarks all reference to 
those strong flyers whose occasional presence in more remote 
localities is due to this power. Dr. Merriam had informed him
