124 Mr. R. R. Parker on 



European specimen in my collection wliich I had thonglit to 

 be the Rame as "subspecies a" (skermani) was in reality 

 undescribed, and is herein given the name S, marskalli, sp. n. 



Sarcophaga shermani, sp. n. 



Holotype (male), collection of R. R. Parker. 



Allotype (female), collectiori of R. R. Parker. 



L'^ngth 11-14 mm. 



Male, — Three rows of black cilia behind eyes ; cheek- 

 vestiture black ; anterior profile outline of forceps-pron^: 

 gently sinuate near tip ; the two pairs of distal processes of 

 penis very slender (longer and more slender than in any 

 other known species of the group) ; posterior spur-like pro- 

 jection of the distal sclerite of penis very prominent (largest 

 and longest of any species of the group) ; first genital seg- 

 ment usually brownish, sometimes brownish posteriorly 

 shading into dull orange anteriorly, less commonly dull 

 orange throughout ; second genital segment dull orange. 

 For illustiation of genitalia, see 2 (p. 45, figs. 6 & 13), and 

 for separation of shermani and sarracenoides, Aldrich, see 2 

 (p. 42). 



Female. — The female presents no characters which permit 

 p.n accurate separation from that of sarracenoides^ though 

 knowledge of the locality of collection will often make 

 identification reasonably certain.

A specimen taken on Savary Island on 12th Aug., 1918, by 

 R. H. Sherman, in whose honour the species is named, is the 

 holotype. 



The specimen taken at Magdalena, New Mexico, lacks 

 prescutellar acrostichal bristles, but this is possibly an 

 individual variation. 



Sarcophaga exuberans^ the form previously designated 

 "subspecies 6" (2), may easily be separated from both sher- 

 mani and sarracenoides by the presence of but two rows of 

 black cilia behind the eyes and of white vestiture on the
