In discussing the paper Mr. Hubbard said that the Evania 

 mentioned by Mr. Cockerell might have been introduced into 

 Jamaica with domestic cockroaches from shipboard, but that, 

 curiously enough, he found this same species in a mountain cave 

 in the interior of the Island of Jamaica, and in an unsettled dis 

 trict. It was there parasitic upon a peculiar cave cockroach. 

 Comparing specimens with others which he obtained in Florida, 

 he could find no differences, and he thinks, therefore, that the 

 species may be indigenous to Jamaica, and that, perhaps, it has 

 been carried from that Island to other portions of the world. 



Mr. Schwarz criticised Mr. Cockerell's paper on the ground 

 that the material collected by the author was far too scanty to 

 warrant generalizations. He found the same fault with the paper 

 by Mr. Cockerell, recently published in the Transactions of the 

 American Entomological Society, on the Coleoptera of the mid- 

 Alpine region of Custer county, Colorado, in which several hun 

 dreds of species recorded from the same region and elevation had 

 been overlooked. The number of species common to Jamaica 

 and the United States must be much larger. In the Coleoptera, 

 for instance, which Salle and Fleutiaux have described from the 

 Island of Guadeloupe, more than 50 out of about 500 are com 

 mon to the United States. So with the Coleoptera of Cuba, and 

 even of Venezuela. 



Prof. Riley agreed with Mr. Schwarz, and spoke at some little 

 length concerning the undesirability of generalizing on insuffi 

 cient grounds. Mr. Ashmead agreed with the preceding speakers 

 as to the superficiality of the paper. Of the genera mentioned 

 by Mr. Cockerell as found in Jamaica and not in the United 

 States, all but 3 or 4 are well known in the United States. With 

 the parasitic Hymenoptera it is altogether too early for even the 

 best informed entomologist to attempt to generalize on questions 

 of distribution. Mr. Howard spoke briefly of the character of the 

 parasitic Hymenoptera collected by Mr. Herbert Smith upon the 

 Islands of St. Vincent and Grenada, showing a fair proportion 

 of characteristic genera and a very large proportion of probably 

 characteristic species. 



Dr. Gill said that Mr. Cockerell might have been influenced 

 in his conclusions, or in his desire to reach conclusions, by
