The Occurrence of a Tropical Butterfly in the 

 United States. 



By C. T. Brues. 



During the month of October, 1899, while collecting insects 

 along the bed of a dried up creek near Austin, Texas, I 

 noticed among the large numbers of butterflies which frequent 

 such places a peculiar species which later proved to be Eubagis 

 (^Dy7iamine>) dionis Hubn.** *>!^ (I have examined specimens 

 of the species in the American Museum of Natural History, and 

 there can be no doubt of its identity). This was the first and 

 last time that I have observed it, although the three following 

 years were spent collecting in the same vicinity. At the time 

 there were numbers of them flying about the mud holes still 

 remaining along the course of the stream, which annually dries 

 up during the summer months. All were in fresh condition, 

 and there can be no doubt that they had been breeding in the 

 locality. What maj^ have been their larval food plant I can- 

 not suggest, as their normal one seems to be unknown. 



The genus Eubagis is strictly neotropical and is represented 

 by some thirty species from Mexico, Central America and 

 South America. According to a note under the .species in 

 question in the Biologia Centrali Americana, this form is re- 

 stricted to Southern Mexico, Guatemala, Nicaragua and Costa 

 Rica, and the opinion is held that it is peculiar to Central 

 America. 



Whence came the numerous specimens in central Texas 

 would be hard to say, especially since they seemed to be breed- 

 ing there. Apparently the summer had been very favorable 

 for the development of insects as Hymenoptera and Diptera 

 were more abundant than I have ever seen them in that part 

 of the country. Among the butterflies, another southern spe-
