146 THE ENTOMOLOGIST’S WEEJvLY INTELLIGENCER, 
formiiifr a library. Now don’t throw 
the hook down directly you come to 
some long hard word, like “ homteote- 
leutan. You can’t expect everything 
to he so easy that it will give you no 
trouble; life would be vapid and insipid 
indeed if there vvere no such things as 
difficulties. Did you ever cross the 
Channel in a dead calm? and didn’t 
you wish for a few waves, just to break 
the monotony of the sea’s appearance? 
If we caught every insect we saw, and 
reared every larva we found, xvilhout 
trouble, why it would be too much of 
a good thing, and we should very soon 
tire of it.

OBSERVATIONS. 
On the S0LENOBI.E OF Lancashire, 
&c. 
Herewith I send, for your examina- 
tion, six bred male specimens of S. in- 
conspicuella and a card with females and 
cases, also seven males of my Triquetrella 
(partly bred) and three females and oases. 
I think, if you will refer to Bruand’s 
work, you will satisfy yourself that these 
are really identical with the species 
he describes as Triquetrella : it is impos- 
sible to make anything out of the j>lates 
representing the males of Inconspicuella 
and Triquetrella. 
The cases of Inconspicuella are found 
here on beech trees in Prestwich Wood, 
and the moths appear early in April, and 
are most sluyyish creatures. The cases 
of Triquetrella are found on large mill- 
stone-grit stones on the moors (occasion- 
ally on stone walls); in order to get them 
it is necessary to turn over these big stones 
(not a very easy job, by the way), as these 
little rascals prefer the sides nearest the 
ground. These insects appear in the per- 
fect state from the 1st to the 20th of 
Maty, and are very active on the wing, 
and, what is very singular in this genus, 
one rarely gets a female. The female 
chrysalis is seen projecting from the case, 
—the insect is missing ; whether its eco- 
nomy is different from that of Incon- 
spicuella, or they become a prey to 
spiders, Coleoptera, &c., I know not : 
what females I possess are chiefly bred; 
the anal aperture in the female is con- 
siderably less woolly than in Incon- 
spicuella. 
These Solenobicc are a very difficult 
group: it is impo.ssihle to know much 
about them without a deal of attention to 
their habits ; hut if my insect is not the 
true Triquetrella, depend upon it is a 
new species. 
The cases found on granite rocks in 
North Wales may sometime or other be
