186 THE ENTOMOLOGIST. 



establishing itself in Mauritius. When we consider, however, that 

 the island is only thirty-six miles in expanse, and therefore a mere 

 speck in the vast expanse of the Indian Ocean, the chance of an 

 involuntary migrant from Beunion, though only one hundred miles 

 off, landing safely in Mauritius is exceedingly remote. I have also a 

 mangled male specimen of H. bolina, which was taken close to the 

 harbour of Port Louis ; it probably came in some steamer, possibly 

 from the Seychelles. I have only seen one otber Mauritius speci- 

 men, which is a female, and it also was taken close *to the town. —

The Hawaiian Entomological Society. — Founded in December, 

 1904, and the first regular meeting held in January, 1905, this little 

 society has already published three parts of its ' Proceedings,' amount- 

 ing to 112 pp. and 2 plates ; while Part 4, with about 40 pp. and one 

 or two plates, is in the press. The society has the distinction of being 

 the only entomological society — or at least the only one publishing — 

 outside of Europe and North America. Its principal object is the 

 study of Hawaiian insects, though other topics are not neglected. 

 The most interesting papers in Part 3 are (1) by Dr. Perkins, describ- 

 ing a new species of Proterhinus from Samoa, this isolated genus being 

 only known from the Hawaiian Islands previously ; (2) by 0. H. 

 Swezey, describing a new genus of Asiracida3, Dictyophorodelphax, 

 with enormously elongate head, resembling that of certain Dictyo- 

 phorinse. 



Note on the Larva of Scotosia rhamnata, Schiff. — When ex- 

 amining the leaves of a buckthorn-bush near Midhurst last summer, 

 I discovered two nearly full-fed larvaa of this species. In colour they 

 closely resembled the larvae of Gonepteryx rhamni, L., and rested in a 

 similar manner on the upper side of the leaf along the midrib, holding 

 on near the base of the leaf with the claspers, slightly arching the 

 abdominal segments away from the leaf, and bending down the 

 thoracic segments so as to touch the leaf again at the apex. They 

 are not easy to see, as they assimilate so well with the general 

 appearance of the leaf, and even when seen may easily be passed over 

 as larvae of G. rhamni. The first moth emerged on 5th July and the 

 second the day following. — H. Leonard Sich ; Midhurst, July, 1907. 



Porthesia chrysorrho3a. — Beading Mr. Adkin's note (p. 164, antea) 

 on the distribution of this species, I recall that when I was at school 

 at Folkestone, and during the summers of 1877, and I think also 1878, 

 we used to come across the larva? in some numbers. I have forgotten 

 the exact locality, but if my memory serves me rightly, it was some- 

 where along the lower Sandgate Road ; probably in the underwood of 

 the little copses near to the sea which were then apparently just 

 planted. I have never collected in the neighbourhood since, and it 

 would be interesting to hear whether the migrants of subsequent 

 generations have established themselves in or near the old haunt. In 

 ' La Feuille des Jeunes Naturalistes ' notices have recently been 

 published of the abundance and also of the disappearance in some 

 localities of chrysorrhcea across the Channel in France. — H. Bowland- 

 Brown ; Oxhey Grove, Harrow Weald, July 8th, 1907.
