butterflies and beetles. Mr. "W. C. Hewitson has described 

 25 new species, but no list of the whole of the butterflies 

 known from Nicaragua has yet been published. In 

 Coleoptera I made large collections, but the extensive 

 families of the ElateridaD, Laniellicorns, and others are 

 still uncatalogued, and very many species remain to be 

 described. The only beetles that have been catalogued 

 as yet with sufficient completeness to warrant any ge- 

 neral conclusions are the Longicorns. I collected about 

 300 different species, and Mr. H. "W. Bates has enume- 

 rated 242 of these in a paper " On the Longicorn Cole- 

 optera of Chontales, Nicaragua/' published in the " Trans- 

 actions of the Entomological Society for 1872." In an 

 interesting summary of the results he gives the following 

 analysis of the range of the species :

Omitting the peculiar species and those generally 

 distributed in Tropical America, we have thus forty- 

 three that are found in Chontales and in Mexico or the 

 United States, and sixty-one that are found in Chontales
