TWO NEW SPECIES OF ANTHOMYIBM, IN THE GENUS 

 FANNIA, E. D (= HOMALOMYIA, Bouche). 



BY J. B. MALLOCH. 



Fannia nigra, n. sj). 

 S ■ Deep black, hardly shining ; eyes bare, very narrowly separated by a 

 black stripe ; frons and epistome hardly projecting- ; jowls descending but little 

 below the eyes ; face distinctly silvered ; palpi normal ; 3rd joint of the an- 

 tenna? about two and a half times as long as the 2nd, arista slightly pubescent ; 

 thorax dull black, unstriped ; abdomen with distinct grey dusting, the black 

 dorsal stripe broadly triangularly dilated on each segment ; anal organ small 

 and inconspicuous ; legs entirely black, fore femora and tibiae with the usual 

 bristling ; mid femora hardly contracted at the tip, a row of about eight strong 

 bristles on the antero-ventral surface from the base to about one-third from the 

 tip, from where it is continued to the tip in a row of very short but strong 

 bristles ; postero- ventral surface with a somewhat similar row of rather weaker 

 bristles ; posterior surface with a row of long, soft, curved hairs ; at the tip on 

 tlie postero-dorsal surface a short row of long, strong bristles, about six in 

 nmnber ; and a few curved hair-like bristles on the antero-dorsal sm-face at the 

 tip ; mid tibia with the apical half slightly thickened, the ventral surface 

 clothed with rather short, but distinct, pubescence, which becomes longer as it 

 nears the tip ; two antero-dorsal and two postero-dorsal bristles present, the 

 upper antero-dorsal bristle about half the size of the usual lower one ; hind 

 femora with a row of bristles on the antero-dorsal surface which ends in three 

 or foiu" stronger and longer bristles at the tip, a row of rather widely placed 

 bristles on the antero-ventral surface, which increase in size as they near the 

 tip, and the basal two-thirds of the postero-dorsal surface with soft hairs, which 

 shorten towards the tip ; hind tibiae with generally two bristles on the antero- 

 ventral surface, and about three bristles above the usiial one on the antero- 

 dorsal surface, the usual dorsal bristles present ; calyptras black, the under 

 scale distinctly protruding ; halteres yellow ; wings infuscated, outer cross vein 

 distinctly waved, last portion of the 4th vein rather more than twice the length 

 of the penultimate ; 3rd and 4th veins slightly convergent. 4 — 5 mm. 



Boiihill and Cardross, Diuubartonshire, 4 (5" c? • June — August. 



The presence of more than one bristle on the antero-dorsal surface 

 of the mid tibia places this species in the same section as carbonaria, 

 Mg. (= corvhia, Verr.), and poiijclneta, Stn., the only two British 

 species with which it can be confounded if this character is attended 

 to. From both of these species it is easily separated by its dull black 

 coloiu* and black calyptra, besides other characters which are quite 

 obvious from the foregoing description. The only other European 

 species that falls into this section is mimitipalpis, Stn., which has the 

 calyptra whitish-yellow, and the palpi very small. 



F. FEMORATA, n. sp.
