BRUES: PHORIDAE OF GRENADA. 505 



This is related to A. arcnafa Malloch from the eastern United 

 States, but is easily separable by the chaetotaxy of the front and 

 by the fact that only one mesopleural bristle is large. In the latter 

 respect it resembles A. juli Brues and A. perdita Malloch from both 

 of which it is otherwise very different. 



Aphiochaeta magnipalpis Aldrich. 



This species was described from specimens taken by H. H. Smith 

 in St. Vincent and Grenada. I collected it again in Grenada. It is 

 a peculiar little species with the mesopleura bare above and the front 

 tarsi noticeably enlarged, especially in the iuale. It may be easily 

 recognized by the bare, greatly enlarged palpi of the male and by 

 the almost parallel course of the fifth and sixth veins in the wing. 



Aphiochaeta aurea Aldrich. 



Originally described by Aldrich from specimens obtained by H. H. 

 Smith in St. Vincent, but also collected by him in Grenada. It 

 appears to be a common species in Grenada as I took numerous speci- 

 mens of each sex in the high central part of the island. 



Aphiochaeta aurea setigera, subsp. no\-. 



Typc.— M. C. Z. 7,008. Grenada, H. H. Smith. 



9 . Length 2 mm. Yevy similar to the typical A. aurea Aldrich, 

 but with a distinct patch of very small bristles at the uj^per angle of 

 the mesopleura; these are not numerous, but always present. It 

 also differs in having the wings without the deep yellow cast and the 

 abdomen without the brilliant orange color usually so noticeable 

 near the center of the abdomen in the typical form. 



Type and three paratypes from Grenada, B. W. I. (H. H. Smith). 

 Two v\ere taken at 500 ft. altitude and the altitude is not indicated 

 on the other labels. * 



This is so similar to A. aurea that it can hardly be considered as a 

 distinct species in spite of the bristly mesopleura which is ordinarily 

 a most satisfactory character. I suspect that it is characteristic of 

 the lower and drier hills while A. aurea is restricted to the higher, 

 moist mountain region as the specimens of the latter which I have 

 labeled as to altitude came from stations at 1,000, 1,500, and 2,500 feet.
