NOLES, CAPTURES, E'TC. 161 
describe. I find (Entom. 1873, vi. 886) a description given of 
two larve of southern TJ’. biundularia by my friend Mr. Porritt, 
but nothing about 7’. crepuscularia. Perhaps some of our older 
entomologists will also give us a little of their experience, so 
that we may be able more readily to determine these confusing 
species with something like clearness, and in future to set some 
of our minds at rest.—JoHn Harrison; 7, Guawber Road,

TEPHROSIA CREPUSCULARIA AND ‘I’. BIUNDULARIA.—I should 
be glad if the casual remark of mine, referred to by Mr. ‘Tutt, in 
his interesting paper last month (Kntom. 98), leads to a full 
investigation of the question of these species. I have bred both 
insects, and made many enquiries from other entomologists, but 
so far I cannot find any clear and satisfactory characters by 
which they can be distinguished in the larval or perfect states. 
I have sought in vain for help from the books of Newman, 
Stainton, and others; and I should now like to quote such 
authorities as Hellins and Doubleday, to show how entirely 
this question remains open. On my consulting him about 
T. crepuscularia and T’. biundularia, Mr. Hellins wrote to me as 
follows :—‘‘ Aug. Ist, 1884. Isend some extracts from Doubleday 
to me, from which you will see that he could not separate 
the larve.” The extracts from Mr. Doubleday’s letters to Mr. 
Hellins are as follows:—“ June 18th, 1859. I have got eggs of 
the pale Tephrosia, which have just hatched. Hope to settle the 
question between biundularia and crepuscularia. I believe they 
are distinct.” “July 11th, 1859. Got a lot of larve of the pale 
Tephrosia (biundularia), but I cannot see any real difference 
between them and those of the darker one. Both vary a good 
deal, but I believe the species are distinct.” ‘‘ Sept. 7th, 1861. 
T’. lariciaria of the old lists were the dark species, which appears 
earlier in the spring than the light one. Crepuscularia has a 
second brood ... Some specimens of summer brood of crepuscu- 
laria very closely approach spring ones of biwndularia.” ‘“ Sept. 
12th, 1861. After being bred in confinement for a year or two, 
all insects degenerate ; and I have lately bred some very light 
specimens of crepuscularia, but feel convinced the species is 
distinct from biundularia.” ‘Oct. 20th, 1861. The dark 
Tephrosia is tar more difficult to procure than the pale one,
