in the sunshine, flying with a straight heavy booming motion 

 like a red bee, and much attracted by flowers of thyme, clover, 

 knapweed, and other low-growing plants. Most abundant on 

 the coast, where it may be found in thousands on cliffs and 

 sandhills ; but also plentiful in chalky districts inland, on 

 the hillsides and in the valleys and pastures ; otherwise 

 rather local, and in some districts absent. Sometimes it is 

 found associating with the other species of the group — as 

 in the west of Ireland, where it occurs along with Z. minos, 

 though far less abundantly — in other cases in the damp 

 meadows frequented by Z. tri/olii. In such a situation 

 Mr, J. J. Weir has found it paired with the last-named 

 species, and has also captured specimens which he believes 

 to be hybrids between the two. There is, however, an 

 element of doubt upon that point, since it is certain that 

 the variety of this species in which the sixth spot is nearly 

 obsolete, is found in places in which Z. trifolii is not known 

 to occur. Most plentiful through the southern half of 

 England to Cambrido-eshire : scarce or excessivelv local in 

 Norfolk ; local also in Pembrokeshire ; common in Hereford- 

 shire and on the Lancashire and Cheshire coasts ; also in 

 some parts of Lincolnshire and Yorkshire, though in others 

 it appears to have died out ; and probably to be found some- 

 where in most of the counties of England and Wales. In 

 Scotland still more local ; found in Fife and Aberdeenshire 

 and other parts o: the east coast ; also in Argyleshire and 

 West Ross. In Ireland widely distributed on the coast, even 

 extending northward as far as the County Derry, but very 

 local inland. Abroad it is plentiful nearly all over the 

 Continent of Europe, except in the coldest portions, as well 

 as in Armenia and Asia Minor. 



(Syntomis Pliegea, L. — A beautiful species, in structure 

 somewhat similar to the Zygcence, but blue-black, with six 

 transparent spots on each forewing, two on the hind, and two 

 yellow belts across the abdomen. A specimen was taken on
