on May 20th, 1914, and subsequently found larvee in the same locality 
on ivy, breeding five of the ab. and seven typical. This year he bred 
six ab. and fifteen typical. He promises to breed from the egg and 
see whether the form occurs also in the second brood; it is to be hoped 
his researches will take a wider scope and furnish a further contribu- 
tion to the study of Mendelism.—L. B. Prout. 
JNOTES ON COLLECTING, Etc. 
Hymenoprera (AcunEata) at Porrucawi.—So little seems to be 
published from South Wales that it may be as well to draw attention 
to the district now and again, in the hope that others will come along 
and help to make its fauna better known. 
Between the mouth of the Ogmore River and the town of Porth- 
caw! lies a stretch of sandhills, known as the Newton Burrows, which 
possesses a very interesting fauna and flora. 
I have spent there two periods of a fortnight each, and a few odd 
days during the last few years collecting Aculeates, and some of the 
results are perhaps worth recording. In all I have taken some 140 
species, of which the following are the more noteworthy. 
Hetrroeyna.—Donisthorpea umbrata and its variety miato-wnbrata, 
D. mixta, and D. aliena. D. nigra is extraordinarily abundant and 
makes ‘‘ grubbing’”’ quite unpleasant. 
Fossores.—Methoca ichneumonides is very abundant, in one restricted 
locality, about the burrows of the Tiger Beetle (Cicindela campestris), 
‘quite 50 females being seen in June, 1915. Tiphia femorata com- 
monly, 7. minuta, very rarely. Pompilus rufipes and P. consobrinus not 
common; P. chalybeatus is apparently the most abundant of the red- 
bodied species; P. wesmaeli, a few males. Salius affinis, a few ; Cero- 
pales maculatus, very abundant, especially at the flowers of the Sea 
Spurge. Astatus stigma, not rare, Tachysphex unicolor is abundant, 
much more so than TJ. pectinipes ; Pemphredon carinatus, one female on 
a Willow stump, in July, 1916. Psen bicolor and P. unicolor, both fairly 
common. (Corytes tumidus rare, Oxybelus mandibularis, two females in 
June, 1915; O. mucronatus is exceedingly abundant, far more so than 
O. uniglumis ; in fact, with the exception of Pompilus plumbeus and 
-Crabro wesmaeli, it must be by far the commonest fossor on the sandhills; 
it appears to provision its nest exclusively with the similarly coloured 
fly, Thereva annulata. The males are very partial to the flowers of the 
sea spurge, and seem to be about on the dullest days. I have taken no 
rare species of Crabro, but Colonel J. W. Yerbury took C. tibialis and 
C. styrius here in 1906. 
Curysipip®.—These do not seem common beyond (. iynita, which 
is of course abundant. I have also taken Ellampus auratus, Hedychri- 
dium integrum, H. minutum, Chrysis cyanea, C. viridula, and C. ruddit. 
AntTHoPHILA.—Colletes fodiens and C’. marginatus are both common, 
C. picistigma much less so; Sphecodes pilifrons common with its host 
Andrena albicrus; S. affinis, common. Andrena nigriceps, a small 
colony was found on a bank close to the sea; A. coitana, one female. 
Dasypoda hirtipes, one male; Epeolus productus, common, FE. rufipes, 
scarce, both at flowers of thyme. Coelioays mandibularis is a very 
abundant sandhill bee, in company with Meyachile maritima, with 
which I suspect it is associated, though I have never seen the Coeliowys
