Coleoptera of Nicaragua 2g! 
corns. I collected about 300 different species, and Mr. H. W. 
Bates has enumerated 242 of these in a paper ‘On the 
Longicorn Coleoptera of Chontales, Nicaragua,” published 
in the Transactions 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 dis- 
tributed 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 and countries 
lying to the southward. The preponderance of southern 
forms is not so great as in the birds, but when we reflect on 
the large number of peculiar species, and that the Longicorns 
of the Atlantic slope of Costa Rica are yet scarcely known, it 
appears likely that many of the Chontales species will be 
found ranging southward across the San Juan river, and that 
the Insect fauna will be shown to have the same relations as 
the Bird fauna; for, as the Atlantic forest continues un- 
broken much further southward than northward, so will the 
insects pculiar to the forest region have a greater range in 
that direction. 
Mr. Hollick has beautifully drawn on wood a few of the 
characteristic Longicorns of Chontales, all of them, with one 
exception (Polyrhaphis fabriciz), being as yet only known 
from that province, but probably extending into Costa Rica. 
One of these, the lovely little Cosmisoma Titania, No. 7 in 
Plate, has been appropriately named after the Queen of the 
Fairies by Mr. Bates. It was first found by Mr. Janson, 
junior, who came out to Chontales purposely to collect 
insects; and I afterwards obtained it in great numbers. 
The use of the curious brushes on the antenne is not known.
