Vespa norvegica in Yorkshire. — On August 11th last, while collecting Cole- 
optei a on umbelliferous plants at Stamford Bridge near York, I captured a specimen 
of Vespa norvegica. — W. W. Fowler, Lincoln : February Sih, 1881. 
Ornithoptera Frookeana, Wall. — This handsome butterfly, which was first 
described by Mr. Wallace in 1855, and discovered by him in the neighbourhood of 
Sarawak, is still, especially the female, not a common insect in collections, but, from 
recent information, it appears to have a much wider habitat than is usually understood, 
and, therefore, also likely befoi’e long to be estimated as a much less rare insect by 
Lepidopterists. Of its having but a limited range in Borneo it would be somewhat 
rash to predicate. From Sarawak, where originally found, it extends northwards 
to Sandakan where it has been captured by Mr. W. B. Pryer, and was seen in N.W. 
Borneo, near Mt. Kina Balu, by Mr. Burbidge, “ Gardens of the Sun,” p. 260. This 
author records it as being seen in considerable numbers : “ These delicate insects are 
generally most numerous by rivers, or in sunny places by the dry beds of streams, 
and, singularly enough, are most abundant during the cool wet monsoon.” It is also 
found in Sumatra, Yollenhoven having described and figured it from that Island under 
the name of F. Trogon. In the Proc. Roy. Geog. Soc., vol. ii, p. 634, it is recorded 
that Mr. Leech found this butterfly “ plentifully in several places ” in Eastern Perak. 
It is thus found in Malacca, Sumatra, and Borneo, but we may almost absolutely 
say not in Java, and thus agrees with the many other zoological coincidences which 
prompted Mr. Wallace some years since to propound the theory “that subsequent 
to the separation of Java, Borneo became almost entirely submerged, and on its 
re-elevation was for a time connected with the Malay Peninsula and Sumatra, but 
not with Java or Siam.” Most of the described Ornithopterce are now in collections ; 
O. Urvilliana has recently been received from Duke of York’s Island, and the 
greatest rarity and desideratum that remains is 0. Tithonus, De Plaan, which was 
described and figured in 1840. — W. L. Distant, East Dulwich : January 22nd, 1881. 
Occurrence of Harpella bracteella near Hartlepool. — Mr. J. E. Robson, of 
Hartlepool, took a specimen of this rare Micro., in his garden, last summer. The 
insect flew to light, which was put in his summer-house for the purpose of attracting 
moths. It is in rather poor condition, but a most interesting capture, as giving a 
fresh locality for the species. The only other recorded captures are those near 
Gateshead, and the one at Crumlyn by Mr. Scott. Mr. Robson most kindly pre- 
sented me with the specimen. — J. Sang, 6, Chestnut Street, Darlington : January 
2oth, 1881. 
On the semi-looping habit of young larva of Noctua.—In reference to Mr. 
Stainton’s remarks ( ante p. 135) on the half-looping young larvse of Triphcena pronuba, 
I have to state that, according to my experience, which has been pretty extensive in 
rearing from the egg, nearly all the larvse of the Trifida are semi-loopers when first 
hatched. The Cymatophoridce are an exception, but they are altogether abnormal, 
and somewhat allied to the Toriricina, the eggs being pear-shaped, and the larvse 
living between united leaves and moulting only four times, while the normal number 
of moults in the Trifidce is five. — R. F. Logan, Colinton, N.B. : February Wth, 1881. 
Fempelia hostilis, rf'e., near Colchester . — I captured a worn specimen of 
Fempelia hostilis in 1879, and in the autumn of that year took several larvse, but
