The small island of Grenada lies at the southern end of the wind- 

 ward group in the West Indies. In spite of its proximity to Trinidad 

 which supports a continental fauna, the insect inhabitants seem rather 

 limited in number of species. When I visited this island in 1910 for 

 another purpose in behalf 'of the Museum of Comparative Zoology, 

 I had the opportunity to collect a number of insects some of which 

 belong to the Phoridae. I was particularly interested in these small 

 flies at the time, and brought back specimens representing nine species. 

 Mr. H. H. Smith collected many insects in Grenada some twenty 

 years before and obtained several species two of which I failed to 

 find in 1910. 



The following list includes the known species from the island includ- 

 ing three which are new to science. 



Paraspiniphora scutellata Brues. 



The type of this species which is a female is from Grenada. I 

 collected a male in 1910, which differs in having the anterior scutellar 

 bristle much smaller than the posterior one. This is probably a 

 sexiuil character. 



Dohrniphora venusta Coquilett. 



This is common in Grenada as in most parts of the American tropics. 

 From specimens collected in Grenada and St. Vincent by H. H. Smith 

 it was redescribed as divaricata by Aldrich. It was also obtained in 

 Grenada by Busck and myself. 



Dohrniphora alleni, sp. nov.
