78 PSYCHE [August 



Syrphidae. 



Mesogramma marginatum Say. A number of specimens were collected by 

 Mr. Davis at St. Georges, July 9. 



Allograpta obliqua Say. A common species of the islands, obtained by Mr. 

 Davis, July 8-1 1. Also reported by Mr. Jones in 1876, and by Prof. Verrill. 



Eristalis ienax Linn. One specimen was collected by Mr. Davis on July 10. 



Lathy rop hi hab}ius aejieus Scop. Two specimens were taken by Mr. Davis, 

 July 14 and 21. This species which is more familiarly known as Eristalis aeneus 

 was also collected by Dr. Fr. Dahl in 1892. 



Sarcophagidae. 



Sarcophaga carnaria Linn. Both Prof. Verrill and Uhler refer specimen to 

 this species. Among the numerous specimens collected by Mr. Davis the true 6". 

 carnaria is not represented. The specimens are nearer S. rabida Walk, also 

 recorded by Prof. Verrill, but the present unsatisfactory condition of our Sarcopha- 

 gids prevents me from positively determining the species. 



Sarcophaga sp. ? A smaller form of which a number of specimens were col- 

 lected by Mr. Davis, July 8. 



Helicobia helicis Town. Two specimens were collected by Mr. Davis. 



Sarcophagula sp. Recorded by Dr. Dahl. 



Calliphora vomitoria Linn. Recorded by Prof. Verrill. 



Lucilia sericata Meig. Numerous specimens were collected by Mr. Davis. 



Lucilia latifrotis Schin, Recorded by Dr. Dahl. and also by Prof. Verrill. 

 Probably only a variety of the preceding. 



Lucilia caesar Linn. Recorded by Prof. Verrill. 



MUSCIDAE. 



Musca domestica Linn. Common. The smaller form in which yellow is the 

 predominating color of the abdomen is the M. basilaris Macq. It hardly deserves 

 varietal distinction. 



Stomoxys calcitrans Linn. Recorded by Prof. Verrill. 



Anthomvidae. 



Ophyra aenescens Wied. A number of specimens were collected by Mr. Davis 

 at St. Georges, July 9 ; also by Mr. T. L. Montgomery in March, 1897.
