ABT. 6 NOTES ON OEIENTAL SAPKOMYZID FLIES MALLOCH 31 



SAPROMYZA (SAPROMYZA) QUADRANGULATA (de Meijere) 



Lauxania quadrangulata db Meijeeb, Tijdschr v. Ent.. vol. 67, p. 48, 1924. 



I have before me a specimen which evidently belongs to this species. 

 It agrees with the type specimen, but is smaller, and has the legs less 

 conspicuously banded, and the abdomen with smaller spots, and with 

 four or even six series instead of but two as in the type. This last 

 character may be variable, as there are traces in the type of additional 

 series of spots besides the two submedian series, and the Philippine 

 example is not fully matured, so accurate comparison is difficult. 



Locality, Mount Maquiling, Luzon (C. F. Baker),
