THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
cleaved of the trees, and the very roots 
grubbed up. I found a few oaks just 
felled, but no Cucujus ; uor have I heard 
that any other collector was more fortu- 
nate ; if he were I should be obliged to 
him for a specimen. The whole of this 
Hainault Forest is doomed to destruc- 
tion ; and if the Cucujus, or any other of 
the rarities peculiar to the place are to 
be taken, there is no time to be lost. 
We have a good deal to learn about 
wood-feeding beetles ; and if those col- 
lectors who can get access to old trees 
will only take the trouble to make notes 
of what they find, we may all be 
instructed. — J. W. L). 
Hymen optkiia. — Simultaneous with 
the appearance of the Andrenida a race 
of parasitic bees will be observed hover- 
ing about, and occasionally entering 
their burrows for the purpose of deposit- 
ing their eggs upon the food stored up 
by the industrious Andrena : these para- 
sites belong to the genus Nomada, a 
gaily-painted race, who “ toil not, neither 
do they spin;” they have been called 
wasp-bees, but they resemble those in- 
dustrious insects in nothing but their 
colouring: of this genus of bees the fol- 
lowing species may be found during 
April : — Nomada borealis, succincta, aller- 
nata, Lathburiana, signata , furva, and 
ruficornis : there are twenty-four species 
of these parasites, which appear each 
simultaneous with the bees whose habi- 
tations they infest. 
Several species of humble-bees may 
now be met with ; all the specimens 
taken will most likely prove to be fe- 
males: these have lived through the 
winter carefully concealed in some snug 
corner ; workers are seldom taken so 
early : the species most frequently met 
with about this period are Bombus ter- 
restris, pralorum, lucorurn, soroensis, la- 
pidarius, hortorum, and about the end of 
the month Bombus muscorum, senilis, 
and sylvarum , usually appear. 
NATURAL HISTORY OF THE TINEINA. 
A resumS of the known Elac/tisla 
larvae will probably be found much to 
facilitate additional discoveries. 
In Dactylis glomerata (a grass which 
any one may know from the main stems 
which branch out from the root not being- 
round, but Jlat) two larvae make linear 
straight mines, viz., E. atricomella and 
luiicomella ; one makes an inflated puck- 
ered mine, E. gangabella, and one makes 
a broad llattish mine at the top of the 
grass-leaf, E. cygnipennella. 
In Holcus mollis (that soft velvety- 
feeling grass), and sometimes in Bromus, 
the broad flat mine of E. rufocinerea 
occurs. 
In Bromus erectus we find the straight, 
narrow, pink-tinged mine of E. subni- 
grella. 
In Bromus asper and Brachypodium 
sylvuticum is the slightly puckered 
brownish mine of E. Megerlella. 
In Air a ccespitosa (that very harsh 
rough grass which feels like a file when 
you try to draw it between the finger 
and thumb) we know of two mines, the 
narrow straight mine of E. albifrontella , 
and the broad mine (occupying the whole 
width of the top of the leaf) of E. Zona- 
riella. 
In the leaves of Poa Aquatica we 
have the rather slender hardly percepti- 
bly paler mines of E. Pore, aud in a 
species of Poa growing under hedges is 
the lnoadish mine of the black-headed 
larva of Elachista Gregsoni ; it was in 
some species of Poa, the pale-headed 
larva of E. nigrella, with which we are 
still imperfectly acquainted, was first 
found. 
In Holcus Mollis, and other grasses, 
the larvae of El. obscurella and its pretty 
consort pulchella occur. 
In a slender short grass on Box Hill 
(the name of which I do not know) the 
larva of El. Bcdellella makes a pretty
