THE LEPIDOPTERA OF AN ESSEX GARDAN, 83 
mation and the reproduction of it, by injury of the larva, has been dealt 
with by Dr. Chapman in the Trans. of the Ent. Society of London. 
The ©. longana series is particularly interesting, and differs much 
from last year’s take. There seem to be two races, one the large 
ordinary yellowish form, and a much smaller silvery white form. This 
at first mieht be thought to be bleached, but bleaching would not 
reduce the size; this small form would appear to be abundant this 
year. Some six or seven Cnephasia chrysantheana with numerous C. 
nubilana complete the list, except for one prize, a specimen of the new 
C. genitalana. One in 800! last year (1916) in about the same num- 
ber there were three specimens; the form taken at Mucking might 
easily be passed as a specimen of OU. subjectana or C. pascuana. Olindia 
ulmana, Argyrotowa conwayana, Dictyopteryx loeflingiana, D. holmiana, 
D. berymanniana, and, D. forskaleana show that this genus is fully 
represented. One specimen of Tortrix viridana! the only one seen, 
shows this species to be a great rarity in the vicinity. The Peroneas 
are poorly represented, three forms of Peronia  variegana, 
and a single specimen of P. sponsana being the only ones 
seen; Teras contaminana occurs abundantly, with many lovely 
varieties. The Conchylidae produeed two specimens of Phtheochroa 
rugosana, Xanthosetia hamana commonly (by the way, what has become 
of its brother, X. zoegana? I used to take it at odd places commonly ; 
now I never see it). Hupoecilia dubitana, one specimen of LH. angus- 
tana, and although not exactly from the garden, Mr. Burrows sent me 
a nice series of H. affinitana from the saltings. Conchylis smeathman- 
iana was abundant, and amongst the series I detected one specimen 
of C. francillana. In the Penthinas a lovely series of Antithesta salt- 
cella (not actually out of the garden), Penthina pruniana and P. varie- 
gana were common ; of the latter was a very handsomely marked speci- 
men of the var, nubiferana, which I had not seen before, and could 
hardly realise it as belonging to the genus at all. A single specimen 
of P. ochroleucana occurred. 
In the Spilonotidae, Sericoris lacunana and Orthotaenia striana were 
abundant. The Grapholithidae are represented by bactra lanceolana, 
Paedisca corticana, Ephippiphora trigeminana one specimen, the only 
Phoxopteryx being P. achatana. A single Grapholitha penkleriana and 
another of G. niyromaculana are augmented by countless thousands of 
every form of G. trimaculana. These Mr. Burrows found so numerous 
that he had to exercise a censorship, otherwise we should have been 
overwhelmed. Hedya ocellana was abundant with its numerous 
varieties ; H. dealbana occurred sparingty with its dark var. ainetana. 
H. aceriana also put 1» a modest appearance, and occasional speci- 
mens of Spilonota trimaculana and S. roborana and Pardia tripunctana. 
Aspis udmanniana was represented by two specimens. A single 
specimen of Retinia buoliana was a curiosity, as with the exception of 
one or two fir trees in the garden I saw no others in the neighbour- 
hood. A single Catoptria citrana, another of C. hypericana, with 
numerous C, fulvana, C. scopoliana, and a single C. cana, represent the 
Catoptrias. The Dichroramphas produced numerous Dichrorampha 
petiverella, with some very fine forms of its variety flavidorsana, a nice 
series of D. plumbagana, a single specimen of Stigmonota compositella, 
one only last year, probably indicates it is difficult to see and capture ; 
two S. regiana, with numerous Semasia janthinana, complete the list of
