Remarks on the Great Oolite of Minchinhamptoii. 115 
suppose to have some influence on the Lepidoptera and Ilymeno- 
ptera ; it is provincially called the potatoe- wood ; it is at that 
time covered with blossoms, which, though they grow in thick 
racemes, offer nothing pleasing to the sight or the scent. But 
these form the centres of attraction to the insects I have named ; 
Pierides and Theclce in particular flutter around the summits in 
considerable numbers, and swarms of small beetles and flies. 
The Bauhinia displays its elegant blossoms, and in one corner a 
large patch of Cassia attracts Papiliones and Coliades) but in 
general there is an almost total lack of the flowering herbaceous 
vegetation that fringes the roads in most other places. It is 
remarkable also that the trees in these woods are nearly, if not 
quite, destitute of epiphyte Orchidacecej which are so abundant on 
Blueflelds Mountain at a similar elevation, that hardly a tree is 
without one or more specimens. But in other respects the cha- 
racter of the vegetation in the two regions differs greatly. 
This district I habitually visited every alternate week, very 
frequently spending eight or ten days at a time with my worthy 
friends at Content. Probably two-thirds at least of my collec- 
tion of insects were the result of my labours here. The eleva- 
tion of the region may be assumed (I speak only from my own 
estimate) as ranging from 1500 to 2000 feet above the sea. 
Before I leave this subject, I would add, that during the period 
of insect-abundance on the Hampstead road, a large number of 
species were taken by flying in at the open windows of Content 
cottage by night. Many valuable specimens occurred in this 
way, not only of the crepuscular and nocturnal Lepidoptera, but 
of other orders in considerable variety. Curculionidce^ Longicornes 
and Lampyridce were very numerous. I am inclined to think 
that a far greater number of insects are active by night than 
by day. 
At length then I proceed to the list of species, deferring the 
notice of a few other less important localities until they arise.
