ON THE SPECIFIC IDENTITY OF TEEIAS SEC ABE AND T. 

 3IANDARINA. 



BY H. PETER, C.M.ZS. 



For the second time I have bred the full black bordered Te> ias 

 Secahe from eggs laid by the extreme foi'm of T. Mandarina ; the 

 latter is simply the form uuder which this species hibernates. 



Some five years ago I succeeded in breeding a few specimens, all 

 of which were good typical Secahe, from eggs laid in the early spring 

 by Mandarina, but hesitated in publishing the fact until I had con- 

 firmed it by further observations. 



T. Mandarina only appears about Yokohama in the autumn and 

 after hibernation in the spring, the intervening broods being Secahe. 



A decided difference is observable in specimens according to the 

 altitude at which captures are made, the Mandarina form appearing 

 much sooner towards autumn in the mountains than on the plains. 

 We may, therefore, conclude that temperature is the cause of the 

 differences in form, size, and coloration of this extremely variable 

 insect. This insect having been described uuder many names, I pro- 

 pose uniting all under the name of Terias mulfifrons, and in a paper 

 in course of preparation will give a list of its synonyms.

HYMENOPTERA AND EEMIPTERA AT DEAL IN JULY AND 

 AUGUST, 1882. 



BT EDWARD SAUIS'DERS, F.L.S. 



I have just returned from Deal, where I have been staying for 

 about three weeks, during which time I have done my best to get 

 together as many rainties as possible. The late Mr. P. Smith always 

 regarded Deal as one of the best localities for Symenoftera in this 

 country, and, knowing the many scarce species that" he took there, I 

 was very glad to have an opportunity of collecting on the same ground. 

 I think I may say that I found the larger proportion of the species 

 that be mentions as occurring there, but two or three which he found 

 in abundance were totally absent, so far as I was able to discover. 

 The year in which Mr. Smith found his best things was 1857, and he 

 gives a full account of hi^ captures in the Entomologists' Annual for 

 1858. No doubt that year, as he says, was unusually hot and sunny, 

 and this year has been thus far less sunny than usual ; still, I did not 

 have a single wet day whilst I was at Deal, and I was certainly sur- 

 prised at the absence of some species and the scarcity of others which
