LOCAL HABITATS. 
sex. Trachynotus foleator. Megachile Leach- 
ella. — Hampstead-heath, Middlesex. Sarro- 
trium muticum. Methoca ichneumonides. 
Hedychrum Toseum. — Battersea Fields^ Sur- 
rey. Allantus dispar. Tropidia milesiformis. 
Helophilus limulatus and frutetorum. 
Marshes. The flowers of buttercups, and 
the rushes, flags, and flowers in ditches, har- 
bour insects of almost all the orders, and often 
in profusion. The morasses of Lincoln, Bed- 
ford, and Cambridge, and Wliittlesea Mere, 
in Huntingdonshire, produce many insects 
which are exceedingly rare in other places. 
Spercheus emarginatus, among many other 
very rare insects, has been taken at the latter 
place at the roots of aquatic plants. 
Mountains, &c. The mountains, and in- 
deed every part of Ireland, Scotland, and 
Wales, are nearly new ground to the foot of 
the collector; they produce novelties in abun- 
dance. To the enterprising, a visit to these 
places would be well rewarded. On Snowden 
Mr. Newman found the splendid Chrysomela 
cerealis. 
Floods. The rejectamenta left by occasional 
floods in the Spring and Summer, should be 
collected as soon as the waters begin to sub- 
side, in large bags, and tied tight at the mouth.
