seen. The larvae of Ampliatella, Scutu- 
latella, Devoniella, Pfaffenzelleri, CcbIu- 
tella, Interruplella and Caudulatella are 
still unknown. 
Here then is a wide field for investiga- 
tion, and though at present we are not in a 
position to furnish the metamorphoses of 
twenty-four species of the family Gbaci- 
laiuidjE, we hope, before the close of the 
present season, by the kind assistance of 
our readers, to see our way a little^better 
in that direction.

ON THE OCCURRENCE OF THE 
RARER BRITISH SPHINGID.t;, 
To the Editor of the ‘Intelligencer,' 
Sir, — It is constantly asserted that the 
autumn-caught or bred specimens of A. 
Alropos and S. Convolvuli, if females, are 
without eggs. If this be true, then, is 
the brood perpetuated in S. Convolvuli 
as in A. Alropos, by fertile females in 
the early summer ? If so, are these 
females in the case of S. Convolvuli a 
foreign importation, or English-born spe- 
cimens freshly emerged or hybernated ? 
In like manner may be asked. What is 
the condition of all female British 
Sphinges emerging in the autumn 
months; are these possessed of ova or 
not ? In A. Alropos it seems acknow- 
ledged that the females which thus 
emerge are all barren. Some think that 
the ova can be found in the autumn-born 
female Sphinges, hut in a small unde- 
veloped state, and that these during hy- 
bernation are matured. 
It seems desirable to settle this point, 
as upou it depends also the question. 
Whether some of our rarer Sphinges are 
continuously indigenous, and thus a series 
of observations should be collected from 
the various captures in spring and autumn 
of the Sphinges, noting the time, place, 
outward condition and anatomical de- 
velopment and maturity, especially res- 
pecting the autumn-born specimens of 
the commoner species, as the Smerinthi, 
inasmuch as we cannot hope to educe 
the truth from a single or a few obser- 
vations. 
I shall be glad to hear from any of 
your readers who have ever noted or will 
note such points, but I especially think 
that such information should be recorded 
in your pages, as it is a question which 
seems to be of far greater interest and 
physiological importance than the ques- 
tion of the double-broodedness of the 
Notodontidae, which of late agitated so 
severely some of our greatest observera. 
I may further observe that our hyber- 
nating Lepidoptera, and any specimens 
occurring at an unusual time, should be 
anatomically examined, as it will probably 
throw light on a subject of which at 
present we know but little. Theory in 
this case is no use ; we require observation 
— fact. 
Yours, &c.,
