Il6 PSYCHE [December 



One example of Callidryas eubule was met with near the summit, flying before the 

 strong northeast wind, and near the same place I found a dead skipper. Most of 

 the insects seen were Hemiptera, the commonest being the black and red "cotton- 

 stainer." There were also many of the yellow-brown wasps ( Vespa ? ) known 

 locally as "Jack Spaniards." About the rim of the crater, more especially along 

 the southern side, there were hundreds of dead insects (mostly Hemiptera) which 

 had apparently been killed by the sulphurous fumes which are continually pouring 

 out. 



As a whole, St. Vincent is rich in insects when compared with Barbados, 

 although there do not appear to be many moths. I found Utctheisa abundant, as 

 on all the islands I visited, but only saw one Noctuid. The absence of the Heli- 

 cotiidac and other similar families is noticeable, as one would think that the hot 

 and damp valleys of this island would offer special inducements to them ; and such 

 a great number is found in Trinidad that it is rather strange none have strayed 

 up here, or been accidentally introduced. The mole crickets (of which there are 

 two species here) are a serious menace to agriculture, being exceedingly abundant, 

 probably as a result of the introduction of the mongoose, which has killed off a 

 large ground lizard which is said to feed on them. 



The "screw worm " fly {Compsomya) occurs, but is not very common. I only 

 observed it once. On the neighboring island of St. Lucia it is numerous, and a 

 great pest to the stock raiser. It is locally supposed to have been brought into 

 that island by ships carrying mules from the Southern States to South Africa. 



A brilliant steel blue mosquito, peculiar to St. Vincent, is abundant in the 

 forests, being found everywhere, but I never met with it in the lower altitudes. 



On the Grenadines, the lowland butterflies of St. Vincent are common ; on 

 Bequia and southward Cystineura hypermnesfra is abundant in the dry woods, and 

 on Canouan we first meet with Phoebis argantc^ which is common from that island 

 to the continent of South America. Pontia numuste is the commonest butterfly of 

 the Grenadines, although not at all abundant on St. Vincent. There are no 

 Papilios, and the large blue The.cla and Dionc jiuio do not occur, although the latter 

 reappears on Grenada. The "Jack Spaniard," so abundant on Barbados and 

 St. Vincent, building its ne.st everywhere under the eaves of houses, under the sills 

 of windows, about the mouths of caves, or under the branches of trees, does not 

 occur on Union Island, although it is very common on Mayreau and the northern 

 Grenadines. The islands to the south of Union are free from this species also, 

 but another wasp, a small black insect with white abdominal bands, known locally 

 as the "maribunta," is common on Grenada ; it builds a large nest, usually rather 

 high up in the trees. 



Mosquitoes are exceedingly abundant on the Grenadines, especially in the
