X. — J^eio Sarcophagidae/row Asia, with Data relattnr/ to 

 the dux Group f. By R. R. Parker, Bozeman^ Montana. 



Dr. G. Bottcher, writing in 1912 (i, pp. 735-736), con- 

 sidered Sarcophaga tuherosa, Pandelld, S. harpax^ and 

 S. exuheranSj Pand., to be varieties of S, tuherosa. In 

 previous papers the writer has followed this practice, treating 

 these and other related forms, more recently described, first 

 as subspecies of S. tuherosa and later as subspecies of 8. dux, 

 Tliomson (2). This grouping has been due to the similar 

 structure of the genital apparatus, especially of the penes, 

 and the constant occurrence of a certain group of external 

 ciiaracters in all these species. Furthermore, the grouping 

 lias seemed advisable as an indication of relationship. 

 Including the three new forms described in this paper, tlie 

 number of recognized members of the group is ten, each 

 added member indicating more strongly tlie really specific 

 value of the differentiating external characters. In future, 

 therefore, the writer believes these forms should be recognized 

 as distinct species belonging to a group within the genus. 

 Tliis group should be known as the c^u.v-group, S. dux being 

 the first described member. 



In his last paper dealing with this group (2) the writer 

 designated two forms as "subspecies a" and " subspecies h" 

 respectively — the one being S, shermani^ sp. n., herein 

 described, and the other aS. exuherans. Which name 

 belonged to which species could not be stated, because of 

 reasons then noted. It is now possible, how^ever, to make 

 the above designations, thanks to Dr. J. Yilleneuve, who 

 k'ndly forwarded a specimen of exnherans, which he had com- 

 pared with Pandelle's type. It was further apparent that a 



* This species was first described by Boheman in 1865 (Ofv. K. Vet.-
