2. Tibife and tarsi black almost throughout lugens,'!KX. 



— Tibiae and tarsi only ringed at their apices with black 3. 



3. Mesonotum very shining, with very sparse hardly noticeable punctures, and for 



the most part quite glabrous (only " antice pube parca tenui vestitum " 

 according to the author's description). Under-side of thorax without black 

 marks glabricollis, Thorns. (= ancilla, Cam.). 



— Mesonotum covered with a very close though fine and short pilosity clearly 



visible in certain lights, its surface distinctly and more or less closely 

 punctured, hence less shining than in glabricollis. Under-side of thorax 

 (especially the breast) often more or less largely black 4. 



4. Clypeus large, its apex produced into a blunt angulation at the centre, and red, 



as is also the labrum. Breast and dorsal surface of 1st abdominal segment 



usually, perhaps always (?), black. Anterior tarsi pale testaceous, not (or at 



least not conspicuously) ringed with black at the apices of the joints.., 



annulata, F. 



— Clypeus comparatively small, and truncate (without production) at the apex, 



whitish (not red !) as is the labrum. Breast in some varieties black, in others 

 testaceous. Abdomen commonly without black (except the saw-sheath). 

 All the tarsi (and tibia;) whitish, each joint conspicuously ringed at its apex 

 with black lincolata, Lep. (= rosce, C). 



NOTES ON THE ABOVE SPECIES. 



A. spinarum is the Atlidlia centifolias of Newport's celebrated 

 essay, the famous or infamous " turnip-fly," whose ravages are 

 mentioned in almost every general work on Entomology, and were 

 the terror of farmers throughout South and East England in the 

 reigns of the last two Georges and of Williain IV, but seem to have 

 ceased entirely (perhaps owing to change in the methods of agricul- 

 ture) since the accession of the late Queen Victoria ! At present the 

 insect is quite a rarity. I know of no one who has taken more than 

 an occasional specimen in recent years, and have myself only met 

 with it three or four times in England, never at any great distance 

 from my own house, and never on turnips or in turnip-fields, but on 

 umbellifers beside the roads which cross our commons. 



Lineolata is extremely common everywhere, and often occurs in 

 considerable numbers ; but I never heard of any mischief done by its 

 larvae, even in fields or gardens where it abounds. Like Mr. Cameron, 

 I have noticed its attachment to Ajuga reptans, but it also haunts 

 many other low-growing flowers, and is frequent on umbellifers. 



Lugens and glabricollis are less common, but neither can be 

 called rare. The former occurs in this neighbourhood from time to 

 time ; the latter I seem not to have found here, but at various seaside 

 localities and also quite in the heart of the Midland counties, so no 

 doubt it occurs here too, though I have overlooked it.
