A remarkable Erycinid from Trinidad, Nymphidiwm mara- 
valica, was also shown, together with one of the small race 
of Adelpha iphicla from the same locality. It appeared from 
the facies of these two that the Erycinid mimicked the Nym- 
phaline. The latter was exceedingly common, while the 
former was very rare. The whole scheme of colouring of 
the two was so similar that it was impossible not to suggest 
that the one was influenced by the other. 
BLACK VARIETIES OF THE LONGICORN BEETLE, GRAM- 
MOPTERA ANALIS Pz., FROM THE OxForRD pIstTRIcT.—Prof. 
Poutton exhibited on behalf of the captor, Mr. Joserx 
Coxuins, three (1918-20) entirely black forms of this species, 
and one (June, 1919) with black legs but the reddish yellow 
abdominal segments of the typical form. Both varieties 
were very uncommon as compared with the type, of which 
examples were also exhibited. 
THE THIRD BROOD OF HEODES PHLAEAS L., FROM THE 
NEWBURY DISTRICT IN 1921.—Prof. PoULTON gave an account 
of the following observations by Mr. A. H. Hamm, and ex- 
hibited the specimens referred to, as also those of Dr. Perkins 
taken in 1911 and 1912 :— 
“The three series of Heodes phlaeas exhibited were all 
captured in the Newbury district, in early September of the 
present year. They are all of the third brood and show (with 
one or two exceptions) the brilliancy usually associated with 
the first brood. In spite of the prolonged drought, they 
equal, and, in some individuals, exceed in size those of the 
second brood. 
“The first locality was a small damp meadow adjoining 
the tow-path of the canal, opposite Ham Mill, visited Sep- 
tember 5, between 11.0 a.m. and 12.30 p.m. H. phlaeas was 
very abundant and the whole series of 30 males and 13 females 
captured on the flowers of fleabane (Inula dysenterica). 
Although the flowers of the devil’s-bit scabious were in 
profusion, the only butterfly seen to visit them was Vanessa 
urticae, of which a very few examples of the second brood 
were on the wing. 
“ The second series, captured September 7, 2.30-4.0 p.m., 
was from Greenham Common—one of the highest and driest
