The Macro-Lepidoptera of the 
places, is here decidedly rare, generally occurring singly; 
this I have also found to be the case in Cambridgeshire. 
The rarest insect included in my list is doubtless Xylomiges 
conspicillaris. It has also been taken at Brentwood in this 
county, and probably only wants looking for. But how ? 
Its habits seem little known, most English specimens resulting 
from dug pupae. Neuria saponarice next attracts attention; 
after that we meet with nothing of any particular interest 
until we come to Agrotis ravida, which has occurred frequently, 
but cannot be said to be common. 
The genus Tceniocampa has seven representatives, T. rubri- 
cosa and T. gracilis being both of rare occurrence in this 
district. Ortliosia ypsilon occurs now and then, and would 
doubtless prove more abundant if worked for regularly among 
willows. 
I have succeeded in finding every species of Xanthia. 
Xanthia gilvago and X. aurago are both of very limited 
distribution in England; the former is, I fancy, more 
generally distributed than is usually supposed; I have met 
with it myself at many places in the eastern counties. It 
may be obtained in the larval state by beating the flowers 
and seeds of the wych-elm from the middle of April till the 
beginning of June. X. aurago I took a single specimen of at 
ivy-bloom in 1880. The remarks I have just made with 
regard to distribution apply equally to Eremobia ochroleuca, 
which I have noticed in many places in this part of England. 
Tetliea subtusa , a species I have never come across, is recorded 
by Mr. Fitch. Euperia fulvago is known as an inhabitant of 
the Maldon district from a single specimen taken by myself 
at sugar on the top of Hazeleigli Hill,—a most exposed 
situation,—although it is generally regarded as a wood- 
insect. The pretty elm-feeding species of Cosmia are both 
abundant, and Aplecta aclvena is far from rare at flowers. 
The only rare Hadena met with is H. genista, which is 
probably of common occurrence; it is an insect not often 
seen, except at rest on fences. Xylina semibnvnnea occurs 
sparingly at ivy-blossom. The genus Cucullia is only repre¬ 
sented by the two common species: in fact, from this point
