ferred to was attracted to a lamp, and stung Mr. Bitterman on 

 the neck. Serious inflammation soon resulted, which, in the 

 course of a few days, developed into a swelling. The swelling 

 increased in size until it became a bag six or eight inches long, 

 and the difficulty did not disappear for over six months, at one 

 time seeming to threaten fatal results. Various Coleoptera and 

 Diptera were also exhibited. Among the latter the common 

 characteristic dipterous insect of the season was Volucclla mexi- 

 cana. The very injurious cattle pest ( Compsomyia macellaria} 

 was also collected in numbers by beating. The troublesome 

 mosquito of the season was determined from specimens taken at 

 San Antonio as Culex pungens, the bite of which resulted in a 

 very disagreeable inflammation. A few of the more common 

 Coleoptera were exhibited, and particularly Pasimaclius cali- 

 fornicus, which has a local reputation of being one of the most 

 poisonous insects in Texas, and goes by the common name of 

 " Cucurazza." 



The paper was discussed by Messrs. Schwarz, Howard, Ash- 

 mead, Benton, and Patton. 



Mr. Schwarz said that as to butterfly migrations in southwest 

 ern Texas he could not speak from personal experience, but he 

 had heard from several persons that this phenomenon is not a 

 rare* one, especially in the spring, and that several species of 

 Rhopalocera are concerned in these movements. One of these 

 species is no doubt the Archippus butterfly, which is not to be 

 seen in southwestern Texas during the early summer, but is 

 again extremely numerous during October and November, on its 

 return migration. Regarding the sting inflicted by Paniscus 

 geminatus, he expressed some doubt that it should produce seri 

 ous consequences ; he suggested that the sting was inflicted by a 

 Pirates or allied genus of Heteroptera, which are frequently 

 attracted by light. Regarding Pasimachus californicus, Mr. 

 Schwarz said that this and the allied P. duplicates are greatly 

 dreaded by the Mexicans throughout southwestern Texas, and 

 the death of numerous persons is attributed to the bite of these 

 beetles. Two other large Carabidas, a Calosoma and a Dicaelus, 

 which occur abundantly in company with the Pasimachus, are 

 not considered as poisonous. In the English-speaking portion 

 of southwestern Texas, along the San Antonio and Aransas
