Notes on Japanese Hispid<e. 



Leptispa Godwini, Baly, from Japan. — There are so few Hispidce known from 

 Japan (only five) that it seems worth while to record the above species as having 

 been captured near Tokio. It is a species allied to L. pygmcea, Baly, from Ceylon, 

 but it is wholly black, and has a small longitudinal sulcus on the head between the 

 eyes, and the apices of the elytra are much more reflexed. I found L. pygmcea in 

 abundance near Colombo, the insects were resting on the stems of a small grass just 

 above water, but if immersed, remained quiescent beneath it. In pygmcea the body 

 beneath is covered with the close pilosity common to some insects (such as Donacice) 

 which are indifferent to immersion in water, but in Godwini the body is smooth, and 

 I have no doubt it is less aquatic in habit.

A Synopsis of the Aphidid^: of Minnesota : by O. W. Oestlund, G-eol. 

 and Nat. His. Survey, Bull. 4. 1887. 



The author of the above-cited synopsis commences with a general description 

 and terminology of the Aphis Family, which is followed by a short account of its 

 metamorphosis. Although it may be well to take note of what Lichtenstein has 

 done as to the metamorphosis of these insects, it is, perhaps, a matter of regret that 

 in this memoir his phraseology of " Pseudogyna migrans," " gemmans," and 

 " pupifera," has been adopted. 



On looking down the list of species, we are struck by the array of new names, 

 and by the paucity of those known to the European Entomologist. That new forms 

 should occur in America is what we might expect, yet every authentic example of the 

 spread across the Atlantic Ocean of European species must be of great general 

 interest, especially when such examples occur where there is no reason to suppose 

 their recent importation through economic sources. 



Without an opportunity of comparing living European and American examples, 

 or at least collating such with coloured drawings, much risk is run of confusion. In 

 this synopsis our suspicions are raised that several familiar friends appear in new 

 dresses. The sub-family Aphidince is restricted to these ins'ects,- which show from 

 six to seven joints in their antenna ; and an attempt is here made to render more 

 easy the identification of species by the use of synoptical tables. These last are 

 admitted to be more or less of an artificial character, and thus they are offered only 

 as " serviceable to the recognition of species difficult to separate." 



The genus Aphis, as was before attempted by De Geer, is here divided into (a) 

 Aphis pemphigini, comprising those species which twist or curl the leaves of plants, 

 and (b) Aphis genuini, which embraces those numerous genera which presumably 

 do not produce contortions of foliage.
