teriorly ; somewhat conic anteriorly, and slightly compressed 

 at the edges of the three first segments, where there is a sharp 

 keel ; the fore-tip is roughish and truncate, and has at each 

 angle a small projecting flattened scale ; the anterior segments 

 rather rugose, the rest finely cross-threaded ; the division lines 

 of the segments occasionally marked with granules ; a row of 

 foveae along each side of the under surface; the hinder end 

 blunt, conic, slightly roughish beneath, with two considerably 

 projecting spiracular processes, each of which consists at the tip 

 of three united divisions ; a shallow lunate depression behind 

 these, followed by a blunt ridge, on which there are four very 

 minute raised points ; behind the ridge slightly sloped ; the 

 anus-mark in a slight hollow on the level of the under surface. 

 Length 2^ lines, breadth ^ths of a line. 



I do not find the fly described in either Meigen or Mac- 

 quart's systematic works. It may be named Anthomyia soncki. 

 It will probably stand near the A. sylvestris and A. cinerea of 

 Fallen. The male is rather narrowish ; the face white, with 

 ferrugineo-testaceous reflections, the under side of the cheeks 

 and lower part of the head pale grey ; a few black stiff hairs 

 along each side of the mouth, of which three stout bent ones 

 stand uppermost ; frontal band ferruginous, sometimes brown 

 posteriorly ; border of the eyes white, as is also a minute spot 

 above the antennae ; sides of the eyes and hinder part of the 

 head with a fringe of black stiff hairs; eyelet triangle, dark grey; 

 trunk and palpi black, the latter very thin, very slightly thick- 

 ened towards the tip ; antennae black, the third joint rather 

 short, oblong, the tip with a fine white down ; the seta black, 

 naked, or, if a high microscopic powe r is used, bristled to near 

 the tip ; eyes brown, naked. Thorax palish-grey, the sides 

 lighter ; the cross suture very distinct ; a large blackish shining 

 patch on each side from before the wings to the shoulder, a 

 narrow dusky line in the middle of the anterior division, cut off 

 by the suture ; behind the suture two obsolete short linear 

 patches one on each side of the middle ; sometimes the back 

 of the thorax is greyer, and there are three dusky lines, of 

 which that in the middle is the most distinct ; the back and 

 sides with stiff black pubescence, arising from black points ; 

 scutellum grey, the extreme edges and the base black ; the tip 

 with long black hairs ; metathorax pale grey. Abdomen strap-
