led to believe is a hybrid. The only other conclusion that I can arrive at is that wo 

 have, in Japan, only one species of Terias, i. e., multiformis, ■which embraces Hecabe, 

 mandarina, Iceta, and Bethesba. 



The mandarina form are now emerging from Hecabe larva ; this is the first time 

 I have reversed the process, although I have often before bred Hecabe from eggs 

 laid by mandarina. — Id. 



Entomological Notes. — The following notes, suggested by reading the October 

 and November numbers of the Ent. Mo. Mag., may prove of interest. 



Pieris brassiccB and rapce have been unusually abundant here this year. 



I have seen Sphinx convolvuli several times in my garden, it would not look at 

 verbenas or petunias, but showed a great partiality to the more gorgeous flowers of 

 Gladiolus. I can confirm all that Mr. Barrett says about its noble flight, and the 

 ease with which it may be observed. 



Mr. Jenner's statement that, " partial migration, * # # * explains the 

 occasional presence of great numbers (of insects) on the sea coast, as every move- 

 ment in that direction is stopped, and the species becomes as it were heaped up 

 there," was curiously ilhistrated by an occurrence that I witnessed in April, in the 

 island of Teneriffe. Behind the town of Santa Cruz stands a range of mountains 

 with a strangely sharp crest, near the summit the southern slopes are carpeted with 

 a small bugloss (£'c/ij«»«) with brilliant purple flowers; on the north side of tiic 

 ridge the ground falls suddenly away in precipitous crags, densely wooded with 

 laurels and laurestinus trees, under the shade of which is the most exquisite fernery 

 ever imagined. A strong wind was blowing from the north, which struck against 

 the clifP, and was turned upwards by it : a large number of white butterflies, Pieris 

 Daplidice, I think, impelled either by curiosity, a love of adventure, or of the 

 beautiful, or what-not, kept flitting up these purple mountain-meadows, and making 

 for the wooded crags ; each as it reached the edge unsuspecting was cruelly swept 

 up into the air, to a height of thirty feet or more, after a brief struggle it succumbed 

 to force majeure, came down again and patiently began anew the ascent of the slope. 

 Here the " heaping up " was literally effected ; P. Daplidice, though common 

 throughout the island, was nowhere so abundant as on this spot. 



Many years ago, in the county of Durham, I remember seeing Larentia didy- 

 mata flying freely over ragwort in bright sunshine, as recorded by Dr. Jordan, in 

 Norway. 



Although not to the point, I cannot refrain from alluding again to Teneriffe ; 

 on a rubbish-heap outside the town of Puerto Cruz, and also in a stubble-field, I 

 more than once observed the gently-fluttering, crambus-like, flight of Ueiopeia 

 pulchella ; on a tall, shrub-like, spurge (? Euphorbia piscatoria) the grandly con- 

 spicuous larvee of Deilephila euphorbicB were abundant in some places ; on the 

 snow-clad (in April) lava streams of the Pico del Teyde, Mr. Wainwright took a 

 specimen of Colias Edusa, at a height of nearly 10,000 feet. — Qr. B. Longstaff, 

 Morthoe, North Devon : November 9th, 1887. 



Probable extinction of Callimorpha dominula at Dover. — For many years past 

 this insect has been locally abundant from St. Margaret's Bay to Kingsdown, near
