PRACTICAL HINTS. : 191 
polychloros and Gonepteryx rhamne (plenty) represented the hyber- 
nators. Macroglossa fuciformis also was taken, and the regular down 
species Huclidia mt, and L. glyphica were in abundance, with a few 
Phytometra viridaria (aenea).  Huchelia jacobaeae and Ematurga 
atomaria were also abundant and several JVentlia maculata were 
observed.—E. P. Picknrr, The Ravenscrofts, Columbia Road, Hackney 
Road, London, N.E. June 7th, 1900. 
Larva or ZEPHYRUS QuERCcUs.—I went to Abbott’s Wood to-day. 
On the whole larve were scarce except those of Zephyrus quercus, 
which were in swarms.—H. M. Epsusrey, F.E.S., Forty Hill, 
Enfield, N. June 9th, 1900. 
CaLLopuRys RUBI IN Surron Parx.—I found Callophrys rubi in 
abundance on Monday last, June 4th, in Sutton Park.—(Mrs.) Mary 
B. Repmayne, Chetwynd Place, Lichfield. 
PORACTICAL HINTS. 
Field Work for July and August. 
By J. W. TUTT, F.E.S. 
1.—The larve of Hupithecia venosata ave to be found in seeds of 
Silene injlata, in July, those of Hupithecia linariata in seeds of Linaria 
vulgaris, in July and August, those of Hupithecta pulchellata in flowers 
of Digitalis purpuralis, in July and August, those of HNupithecia 
plonbeolata on flowers of Melampyrum pratense, in July and August. 
2.—The larve of EHupithecia valerianata feed on flowers of 
Valeriana officinalis in July. 
3.—The fullfed larve of Anarta myrtilli may be swept from 
Calluna vulgaris in July and again in September (Newman). 
4.—The larvee of Malacosoma castrensis can be reared readily on 
chrysanthemums ; cover a plant with a muslin net, leave them until 
they spin up, then clip off the cocoons and put in a breeding-cage 
(Button). 
5.—The imagines of Acidalia enutaria fly most freely at dusk, 
and may be found almost throughout June and July; there are two 
distinct broods (June and August) in the Isle of Wight, in the marshes 
fringing the Yar. 
6.—The larve of Yylina semibrunnea are to be found on willow 
and ash in July (Croydon and Hackney Marshes) (Machin). 
7.—The plants of Typha latifolia, with yellow central leaf, want 
cutting down in August for larvee of Nonagria arundinis. 
8.—The larve of Hupithecta isogrammata are to be found in flowers 
of Clematis vitalba in August; a little black spot distinguishes the 
affected flowers. 
9.—The larve of Hupithecia pimpinellata feed on seeds of Pimpi- 
nella savifraga in August and September. 
10.—The larve of Hupithecia subnotata feed on the flowers and 
seeds of Chenopodium in August and September. 
11.—Larve of Huclidia mi occur on sandhills feeding on sea 
marram-grass ; drop off when disturbed and twist into grotesque 
attitudes and feign death ; the white mottled colour and shape exactly 
imitates the exuvie of snails (Helix nemoralis) (Kane).
