94. Thorybes pylades Scud. Common everywhere in June and 



July. 



95. Pholisora catullus Fab. Common everywhere. June to Sept. 



96. Pholisora hayhurstii Edw. Very common in the northwest. 



Collections in the southern half of the State show a sur- 

 prising absence of this species. June to Sept. 



97. Thanaos brizo Boisd.-LeC. One specimen at Muscatine. It 



is reported from Omaha, Nebraska, as occurring rarely in 

 April and May (Mr. R. A. Leussler, Ent. News XXIV, 

 352, 1913) and so may be expected in southwestern Iowa. 



98. Thanaos persius Scud. Rare. Distribution general. May to 



July. 



99. Thanaos martialis Scud. Fairly common. Distribution general. 



Occurs in July. 



100. Thanaos juvenalis Fab. Common. May to Sept. Found 



throughout the State. 



101. Thanaos horatius Scudder and Burgess. Rare. There are a 



few specimens at Grinnell and two taken at Sioux City in 

 the writer's collection. The latter were taken on June 23 

 and July 24. 

 103. Hesperia montivaga Reakirt. Very common in all parts of the 

 State from May until late fall. 



In presenting this list the writer wishes again to emphasize 

 the fact that no records are used without adequate proof of 

 their accuracy. The two exceptions are, it seems, amply ex- 

 plained. Where doubtful specimens have come to hand they 

 have been referred to authorities. Thus the list has been made 

 as complete and as accurate as possible and it is now ofifered to 

 the world as a contribution from the Lepidopterists of the 

 State of Iowa. 



Medal Awarded for Entomological Research. 



The Crisp Medal and an award of £30 by the Council of the Lin- 

 nean Society of London have been bestowed upon Mr. R. J. Tillyard
