REPORT ON THE ORTHOPTERA OF TRINIDAD, 

 WEST INDIES. 



By Lawrence Bruner, 

 Lincoln, Nebraska. 



Several years ago Mr. H. I). Chipman collected insects on the 

 Island of Trinidad, British West Indies, and the writer secured a 

 fairly complete set of the Orthoptera taken by him. Since that time 

 a few additional forms have been obtained from G. E. Tryhane, of St. 

 Anne's, Trinidad, and others from W. E. Broadway, of St. George's 

 Grenada, who formerly collected on Trinidad. Altogether upwards 

 of one hundred (112) species have thus been accumulated and form 

 the basis of this paper. 



Unlike others of the West Indies, this island is more closely related 

 to the South American mainland in its fauna than they. Still a rather 

 large number of new forms are described herewith, showing how very 

 interesting is the study of island faunas, although but little removed 

 from the mainland. 



In 1892 Brunner von Wattenwyl and Prof. Joseph Redtenbacher 

 published a paper on the Orthoptera of the Island of St. Vincent.* 

 A little more than a year later Brunner von Wattenwyl reported on 

 the Orthoptera of Grenada. f In the former paper fifteen and in the 

 latter nine new species were described. Quite recently Mr. Jas. A. 

 G. Rehn published some " Notes on West Indian Orthoptera, with a 

 List of the Species Known from the Island of Porto Rico."]; 



In the first- mentioned paper 62, in the second 56 and in the last 

 59 species are listed. Aside from these faunal papers on the Orthop-
