ART. 15 NOTES ON ACALYPTRATE FLIES MALLOCH 19 



two-thirds of the face length; aristae distinctly haired to beyond 

 middle, the longest hairs fully half as long as width of third anten- 

 nal segment; face projecting from middle to epistome; foveae deep; 

 labrum higher than width of third antennal segment, palpi as wide 

 as latter. Thorax without distinct anterior marginal, humeral, and 

 mesopleural bristles ; lower posterior angle of hypopleura with micro- 

 scropic soft hairs. Fourth visible abdominal tergite about twice as 

 long as third in male, about 1.5 as long in female. Legs without 

 exceptional armature; fore tarsus slightly dilated apically in both 

 sexes. 



Length, 10-11 mm. 



Type.—M2L\Q, Cat. No. 43066, U.S.N.M. Allotype, and one male 

 and three female paratypes, Montalban, Luzon, P. I. (C. F. Baker) ; 

 two male paratypes, Dilang, Cavite, P. I. (R. C. McGregor). 



The subgenus is named in honor of the late C. F. Baker. 



CAROLIMTIA PLAGIATA (Bezzi) 



Elassogaster plagiata Bezzi, Philippine Joum. Sci., vol. 12, sec. D, p. 135 

 (1917). 



The female example in the Museum collection is apparently much 

 less conspicuously marked on the wings than was the type female 

 described by Bezzi, but by turning the wing to a certain angle the 

 large dark mark in front of the outer cross vein may be faintly dis- 

 tinguished. I figure the wing, as should the form now before me be 

 the normal one it would be difficult for anyone to identify it from 

 the description alone (fig. 7).. 



Structurally the species is very similar to diptera^ but the sharp 

 tipped apical spur of the mid tibia and the presence of a few fine erect 

 hairs on the supraspiracular convexity of the postnotum will readily 

 distinguish it if taken in conjunction with the duller blackish-blue 

 color of the thorax and abdomen and the wing markings. 



Length, 11 mm. 



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



The Museum specimen bears a number, " 3923," indicating that it 

 was one of a pair, the other being sent to Bezzi. 



Bakeromyia, new subgenus 



In addition to the characters listed in the key for the distinction 

 of this subgenus from its allies it may be worth mention that there 

 are always two quite well-developed bristles on the outer side of 

 each hind coxa, while in the preceding subgenus there is either one 

 or none. For other characters see the descriptions of species below. 



Suhgenotijpe. — Bakeromyia calcarata (Macquart). 



The four species which I place in the subgenus may be distinguished 

 as below.
