THE 
ENTOMOLOGIST’S CALENDAR, 
EXHIBITING TIIE TIME OF APPEARANCE AND IIABITA. 
TION OF NEAR THREE THOUSAND SPECIES OF 
BRITISH INSECTS. 
I \ forming the following Calendar, 1 have been apxious to render it as 
extensive as possible, and at the same time to introduce as many species 
of insects as my own knowledge of the subject, and the few woiks that 
have hitherto been published relative to British Entomology, could make 
it. In the times of appearance, and the situation where found, of a great 
niimber of species, 1 have been greatly assisted by my kind and much 
respected friend J. F. Stephens, Esq. F.L.S. whose rich cabinet has 
always been open to me, and who also has furnished me with much valu- 
able information, derived from his own observations. In many species I 
have been unable to give a reference to a description, several ot them 
being new to Britain, and hitherto undescribed ; but thought it best to in- 
troduce them, as they are certainly valuable acquisitions to a cabinet. 
As many of the Linnean genera have not yet been sufficiently investi- 
gated, arid' the species requiring a minute, examination, such genera and 
species are distinguished by italics. Of these tire most extensive are the 
Lepidoptera, the genera of which are the least known in any department 
of Entomology. “ Of the Hemiptera, Keuroplera, Hymenoptera, and Di- 
ptera, but little is yet known of the species, consequently a very small 
number is introduced : however, they may be obtained in the course 
of collecting. I may be censured by the scientific Entomologist for in- 
troducing the English names of the Lepidoptera, but my object has been 
to render this a useful work ; and many collectors are acquainted with 
them by no other name; yet it is to he hoped that these will hereafter be 
discontinued, as the scientific name is as easily' retained in the memory 
(if a person uses himself to it) as the absurd English ones in present use. 
The species marked by the asterisk (*) I am rather doubtful it found 
in the month in which they arc placed in the calendar; but such is the 
time of the plants on which they feed being in blossom, which is certainly 
a good guide to the Entomologist. 
The obelisk (f) to the plant in tire habitation denotes that such insects 
are generally found in the larva state, and should be sought for accord- 
ingly the insect being rare or difficult to procure in the perfect state. 
©’This mark, placed in other times of appearance, denotes that they 
may he found in such situations throughout the year. 
As many of the Lepidoptera last but a few days in the perfect state, I 
have distinguished the time of the month in which such species appear by 
the following: b. beginning: m. middle; r.. end; — also, /. larva: p. pupa.
