382 Tachinidae. 



abnormal specimen of this species with the second bristle on front 

 tibiæ not developed. Villeneuve also determined it as rutilla, but 

 at the same time declared that it might well be leucophaea Rond., 

 but abnormal by the presence of numerous, robnst disoal bristles. 



83. Tacliina Meig. 



Species of medium or rather large size, and of black colour with 

 pale pruinosity. Head a little broader than thorax, a little convex 

 behind and a little puffed out below, higher than long. Frons in male 

 a little narrower than or about as broad as the eye, in female broader^ 

 somewhat protruding. Cheeks rather broad; jowls one third of the 

 height of the eye or less. In both sexes ocellar and strong inner ver- 

 tical bristles, in female also outer verticals and two orbitals; small, 

 more or less individualised outer verticals may also be present in 

 male. Relatively large postocellar and occipital bristles. Behind 

 postocular bristles no black hairs. Frontal bristles descending to the 

 middle of the cheeks or below, the lower placed in the middle between 

 epistoma and eye-margin; the two uppermost strong and reclinate 

 in both sexes. Cheeks bare. Vibrissæ more or less ascending, from 

 about one third of the height to above the middle. Eyes bare, or 

 quite slightly pubescent. Epistoma somewhat retreating and a little 

 reflected below; it is produced a little below the large vibrissa. Oral 

 cone and proboscis of medium length; clypeus forceps-shaped. Palpi 

 thin, thread-like. Antennæ inserted somewhat or high above middle 

 of the eye, third joint somewhat longer than to fully twice as long 

 as second; arista with second joint short or slightly elongated. Thorax 

 rectangular or almost quadratic; three or four postsutural dorso- 

 centrals, and three præ- and three postsutural acrostichals; a præ- 

 sutural intraalar bristle present, in riistica often wanting. Scutellum 

 with four marginal bristles on each side, the apical the smaller, erect 

 and crossing. Three sternopleural bristles. Pteropleura with a couple 

 of bristles above. Abdomen cylindrical or elongated conical; excava- 

 tion on second segment reaching hind margin ; there are only marginal, 

 or both marginal and discai bristles; second segment with a pair 

 of marginal; fifth segment with bristles on most part. Genitalia 

 small; upper forceps not cleft; arms of lower forceps more or less 

 scale-like. Legs somewhat robust, especially femora, with strong
