ART. 6 NOTES ON ORIENTAL SAPROMYZID FLIES MALLOCH 21 



the type sent to me by Doctor de Meijere discloses that it belongs here. 

 I do not know latifrons Thomson which Frey lists in this genus. He 

 suggests its being the same as ocellaris Kertesz, but does not record it 

 from the Philippines. As already indicated I have not seen cyaneos- 

 toma Frey, which is a black species with a large yellow pleural mark 

 and pale bases to the tarsi, and suspect that it does not belong here. 

 It is from the Philippines. 



Genus MELANOPACHYCERINA Mailoch 



This genus is distinguished from Pachycerina by the possession of 

 4 pairs of dorsocentral bristles (1 + 3), and a preapical anteroventral 

 comb on the fore tibia. There are three species assigned to the genus 

 as below. 



KEY TO THH SPECIES 



1. Ooellar bristles quite large, divergent aud forwardly directed; frontal orbits 



glossy black, sharply differentiated from the velvety black interfrontalia, 

 narrowest just in front of ocelli, and gradually widened to anterior margin 

 at which point each is wider than the space between them; fore femur 

 with at least two bristles on apical half of posteroventral surface. 



leucochaeta (de Meijere). 



Ocellar bristles indistinguishable ; interfrontalia not narrower at anterior 



margin than in front of ocelli ; fore femur with one posteroventral bristle. 2. 



2. Face bicolored, black and fulvous, with a conspicuous transverse depression 



on lower half; posthumeral bristle about as long as the dorsocentrals ; 



fore legs entirely black except the coxae and knees albiseta (Hendel). 



Face entirely glossy black, evenly and prominently convex ; posthumeral 

 bristle very short and weak ; fore legs mth apical halves of tibiae, and the 

 coxae, white, the femora yellow at bases, darkened at apices, basal halves 

 of tibiae and all of tarsi black varipes Mailoch. 



MELANOPACHYCERINA LEUCOCHAETA (de Meijere) 



Pachycerina leucochaeta de Meijekb, Tijdschr. v. Ent., vol. 57, p. 256, 1914. 



This species occurs in the Nederland Indies and Formosa, and 

 Doctor Frey records it from the Philippines. 



It is a conspicuous black species about 5 mm. in length, with 

 hyaline wings. 



The other species occur in the Nederland Indies and should be 

 found in the Philippine^, I consider Ccmiptoprosopella angustilwi- 

 hata de Meijere is albiseta. 



Genus LAUXANIELLA Mailoch 



One species from Formosa has been assigned here, tenuicomis 

 Mailoch, It is very similar in general appearance to M. leucochaeta.
