anterior pair well behind the suture, and shorter than the second pair ; 

 lower anterior part of mesopleura with the hairs long and setalose.

Tyye^ male and allotype, Mount Maquiling, Luzon Province : para- 

 type male, Butuan, Mindanao (C. F. Baker). 



The species of this genus in the Orient present very good charac- 

 ters in the structure of the male hypopygia for their separation, but 

 these characters have not been used to any extent in describing the 

 species from this or any other region and it is difficult to distinguish 

 some of them on color alone, as they are very similar in appearance. 

 A comparison of the figures of the hypopygia in this paper indicates, 

 if the structure of these organs indicates anything, that there are 

 four groups in the lot: tubifera. nigrohnlfcrata, and 'pliilippinensu, 

 representing separate types, and ohscura, qiutdrisplnosa, luteltarsis, 

 and fiLSCofasciata another. Only tuhifera lacks the facial elevations. 

 It is noteworthy that the American species with elevations on the 

 face, and also the genotype of Minettia, have entirely different hypo- 

 pygia from this oriental gi'oup, there being no heavily chitinized 

 inner hooks present. It is, of course, impossible to find correlated 

 genital characters in the females, so that no groups can be based upon 

 the structure of the male hypopygia, no matter how distinctive this 



may be. 



Genus SAPROMYZA Fallen 



I have before me at this time 16 oriental species of this genus 

 which is not so abundantly represented here as in some other regions. 

 Of these species one belongs to a segregate which I consider is en- 

 titled to subgeneric distinction, and it is treated thus herein. To 

 facilitate identification of the species I present a diagnostic key. 



KEY TO THE SPECIES 



1. Fore femur with an auteroventral comb of minute black bristles apioally ; 

 thorax black, with tv.o broad submedian white-dusted vittae, and three 

 pairs of strong dorsocentral bristles, the anterior pair close to suture ; 

 abdomen black, with a yeUowish dorsocentral line on apical three or 

 four tergites, and apices of all tergites white dusted ; wings grayish 

 liyaline, base and outer cross vein slightly fuscous clouded. 



albocincta (de Meijere). 

 Fore femur with an anteroventral comb of minute black bristles apically : 

 thorax yellow, with four pairs of dorsocentral bristles (l-f3) ; abdomen 

 yellow, with a large blackish mark on each side of each tergite except the 

 basal one, which gives the dorsum the appearance of having a broad 

 blackish vitta on each side ; wings yellowish hyaline, outer cros.s vein and 

 apices of veins 2, 3. and 4. conspicuously clouded with fuscous. 



omei, new species. 



Fore femur without an anteroventral comb of minute bristles ; thorax and 



abdomen not colored as above; outer cross vein not clouded 2.
