IV. REVISION OF THE ORIENT A I. BI,OOD- 



SUCKING MUSCID^ {STOM OXIN M , 



PHILMMATOMYIA, Aust., AND 



PRISTIRHYNCHOMYIA , 



GEN. NOV.)- 



By E. Brunetti. 



In the present paper, sixteen species are regarded as probably 

 distinct, belonging to the group Stomoxincs. I have also estab- 

 lished a new genus Pristirhynchoniyia, with one species, allied to 

 Mr. Austen's recently created genus Philcematomyia. 



These latter two genera certainly belong to the group of genera 

 immediately approximate to Musca, whatever this group may 

 be called. The arrangement of genera in Muscidae in the 3rd 

 volume of the Palaearctic Catalogue contains several associations 

 with which I can hardly concur ; especially the placing of the genus 

 Musca itself in Anthomyidfe, and the abolition of Oestridse as a 

 family. 



Two genera not yet found in the Orient are included amongst 

 these descriptions, that they may be recognised should they occur 

 here. 



One {Hcematobosca, Bezzi) is European, and may occur in the 

 Himalayas or in North-West India ; the other {Slygeromyia, Aust.) 

 is African, and might easily be imported through the agency of 

 cattle traffic. 



That the species are generally closely related to each other is 

 easily realised by the number of synonyms even amongst the few 

 European species. Stomoxys calcitrans, L., has been described seven- 

 teen or eighteen times, Hcematobia stimiilans, Mg., possessing six 

 synonyms and Lypcrosia irritans, E., a comparatively uncommon 

 species, two. 



I have little doul)t of the specific distinctness of all the forms 

 described in this paper, with the exception of the genus Stomoxys, 

 of which a considerable amount of further study seems imperative. 



At times it has even occurred to me that all the so-called species 

 from the East could almost be comprised under three typical 

 forms, which may be termed calcilrans, E., in die a , Picard, and a 

 species with a distinctively formed fore tarsus in the o" (the only 

 sex known) — piilla, Aust. 



For this reason I cannot feel satisfied with the tabic of species 

 in Stomoxys, and in this genus the present article must be regarded 

 as more preparatory than conclusive.
