SARCOPHAGA AND ALLIES 213 



ent margin in front. Fifth sternite brownish-yellow, 

 stout at base, with widely divergent arms which are 

 covered on the inner edge with a dense cluster of 

 rather long black bristles, becoming less dense out- 

 wardly. Fourth abdominal segment with a more uni- 

 form row of stout bristles than in hillifera. 



Female. Front narrowest at vertex, where it 

 is .279 of head (average of three,— .271, .279, .286) ; 

 apical scutellars as long and strong as the adjacent 

 marginals, divergent; row of marginals on fourth 

 segment notably stout; genital segment red; its side 

 pieces separated above by a triangular sclerite. Legs 

 not villous, middle tibiae with two spines on outer 

 front side. 



Length of male, 15 mm; of female, 13 mm. 



One male, three females; the male is from Nas- 

 sau, Bahamas, collected December 16, 1912, by F. 

 Knab ; the females are from Miami, Florida, collected 

 November 30 and December 1 and 2 by C. H. T. 

 Townsend.

Williston, Trans. Ent. Soc. Lond., 1896, 364, male (the

I examined a cotype of each sex in the American 

 Museum of Natural History, and was permitted to 

 spread the genitalia of the male, from which I made 

 the sketch reproduced in Fig. 101. 



The species is closely allied to hillifera, but has 

 golden face and yellowish pollen on thorax; Willis- 

 ton noted the absence of ocellars; the forceps are 

 rather straight in general shape, with minor undula- 

 tions, and have a peculiar oval concave space on the 

 outer side, different from anything else that I have 

 seen. By an oversight, I did not complete my notes 

 on the type, and cannot give a detailed description, 

 but it would hardly be necessary with the ascertained
