NATURAL - HISTORY NOTES. 
A New Species of Drosophilid Fly, by David Miller. 
Upon going through a collection of various species of Agaric, Mr. E. H. 
Atkinson, of the Government Biological Laboratories, found several speci¬ 
mens infested by dipterous larvae, which he handed to me for identification. 
On these larvae being bred out it was found that they belonged to a new 
but common species of the genus Leucophenga (fam. Drosophilidae); this 
species is herewith named after Mr. Atkinson. 
Leucophenga atkinsoni n. sp. 
A small brownish-yellow fly with pinkish eyes when alive, and several 
transverse yellowish bands alternated with brown ones across the abdomen. 
Fig. 1 .—Leucophenga atkinsoni ; head and thorax (side view). 
Eyes broadly dichoptic, minutely haired, pinkish-red when alive but 
becoming dull red after death ; 1st and 2nd antennal joints yellowish- 
brown and bristly ; 3rd joint blackish-brown and pubescent; arista feathered 
with long hairs above and below and with a row of very short ones 
above (fig. 1); front and vertex yellowish-brown, chaetotaxy as shown in 
fig. 2 ; face, narrow parafacials, and epistoma tawny ; clypeus distinct, 
yellowish-brown but somewhat silvery at times and with two narrow trans¬ 
verse darker bands ; cheeks, oral margin, and occiput yellowish-brown but

shown in fig. 1 ; proboscis pale yellowish-brown with long and short delicate 
hairs on lower side, labella clothed with delicate hairs ; palpi clavate,
