By Maurice T. James : 



Fourteen species of Stratiomyidae are represented in the collections, 

 9 or probably 10 of which apparently are new to science. Three of the 

 previously known species, Hermetia illucens (Linnaeus), Microchrysa 

 bicolor (Fabricius), and Sargus notatus Wiedemann, are widespread 

 throughout the Neotropical Region, although the last of these is rep- 

 resented, as noted below, by an Antillean form that differs in appear- 

 ance from most mainland material. The interesting distribution of 

 Artemita inornata (Willis ton) is discussed under the heading of that 

 species. The remaining species, except the unnamed Nemotelus and 

 the new Pachygaster, show distinct Neotropical affinities. Cyphomyia 

 dominicana is a member of an Antillean complex, with a closely
