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

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

 mandarina, Iceta, and Bethesba. 



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

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

 laid by mandarina. — Id. 



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

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



Pieris brassicte and rapcB 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 gi-eat partiality to the more gorgeous flowers of 

 Gladiohis. 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 tlie 

 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 illustrated 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 {Echiiim) with brilliant purple flowers ; on the north side of the 

 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 sti-ong wind was blowing from the north, which struck against 

 the cliff, 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 pui-ple 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 inajeure, 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 larvffi of Dellephila euphorbicB were abundant in some places ; on the 

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

 specimen of Colias Edusa, at a height of nearly 10,000 feet. — Gr. B. Longstaef, 

 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
