tained several patclies of eggs. This visitation Avas spread over many 

 hundreds of miles. 



Mr. S. H. Scudder stated that he had recently received a 

 collection of butterllies made by Mr. J. A. Allen, in Iowa ; 

 there were forty-six species in all, three of which Avere new. 



One, Chrysophanus Dlone, was of about the same size as the C. 

 Thoe ; the sexes were nearly alike in their markings; the upper sur- 

 face was of a grayish brown, with faint violet i-efleetions; the prima- 

 ries had two black spots in the cell, and the hind margin of the 

 secondaries was bordered somewhat as in C. Thoe; beneath, the col- 

 oration and markings were similar to those of C. Thoe, but the spots 

 on the secondaries were differently arranged. The second species, 

 an Apatura, for which the specific name Proserpina was proposed, 

 differed from the species of this genus hither;o found in the United 

 States, in having well rounded hind wings. The coloration agreed 

 in general with that of ^-1. Cli/ton, but the markings were more dif- 

 fused, the spots more indistinct, and the insect itself much larger, 

 expanding two and two-thirds inches. The third species, Hesp)eria 

 Iowa, differed from //. Delaware Edw. in having dulhn- colors, a much 

 broader margin, and a longitudinal streak along the middle of the cell 

 in the primaries of the female. 



Mr. Scudder also exhibited two fossil insects from the coal 

 measures. 



One was found in the iron-stone nodules of Morris, Illinois, which 

 have previously afforded remains of insects. The fragment repre- 

 sents the wing — apparently an upper one — of a neuropterous Insect, 

 which he called Aler/athentomum pustulatum. It is gigantic in size, 

 very broad, with distant nervures, simple and slight divarications, and 

 in the outer half of the wing, which alone is preserved, a cross neu- 

 ration, composed of most delicate and irregular veinlets. The wing is 

 also furnished with a large number of larger and smaller discolored 

 spots, the surfaces of the larger ones irregularly elevated. 



The vena mediastina is simple and straight; the vena scapukirit 

 sends out two branches fi-om its upper side, the first of which does net 

 reach the border but loses itself in a congeries of minute veins, while 

 the second, branching again quite near its origin, supports the tip of 

 the win"-; the vena externo-media occupies the middle third of the 

 wing, and divides once near the base; each branch is straight and 

 forks again, the upper one a little nearer the border than the second 

 divarication of the vena scapularis, the lower still nearer to the mar-
