lowlands of Carriacou ; and unless a person travels with a net, sleep is almost 

 impossible. They appear during the wet season, from June to November. 



The parasol ant or "gros-tete" is numerous on Carriacou, where it was prob- 

 ably introduced from Trinidad by small trading boats plying between the two 

 islands, as it does not occur on the other Grenadines, nor on Grenada. This 

 insect is a great pest, making it impossible to raise roses and a number of garden 

 vegetables and other plants. It is very fond of the flowers of the red hibiscus. 



On Carriacou also there is a large millipede, locally called the "congeree,'' 

 which appears here to have reached the northern limit of its distribution. Jt is 

 very common on the higher lands, and a banana or mango skin thrown down any- 

 where soon becomes a mass of them. 



The butterflies noticed on Grenada were the same as those on St. Vincent, 

 witli the addition of the two species {Cys/ineura hypermnestra and Phoebis argante) 

 which do not extend farther than the Grenadines, and also Historis odius and 

 Avartia amathea. Fapilio polydavius and the large blue Thecla of St. Vincent are 

 lacking. Erebus odora and Herse cingulata are common here, and on Carriacou, 

 and very likely on St. Vincent as well, although I did not find them on that 

 island. 



The object of my trip to these island was to make a study of the birds, and I 

 unfortunately found it impossible to bring back a collection of insects ; but 1 am 

 sure that this region, where the South American fauna meets the West Indian, 

 would yield most interesting results to the student of geographical distribution in 

 insects, as it has in regard to its birds and mammals; besides which a host of new 

 forms would be brought to light, as shown by the results of collections which have 

 been made on St. Vincent and on Union Island.
