ON VAEIOUS GENERA OF BRITISH APHIDES (IIOMOPTER.A). 



BY r. LATXG, M.A., B.Sc, F.E.S. 



(Published with the permission of the Trustees of the British Museum.) 



Tlie present paper deals with certain Apliidae described by Walker, 

 Avbicli have remained in obsem-ity since bis time, and with wliieh 

 subsequent authors have never dealt. It is quite impossible to assign 

 Walkei''s species to their proper genera from his descriptions alone ; he 

 gives few morphological details, and where he does, they are often mis- 

 leading or erroneous. This is particularly noticeable in the case of 

 those species which he did not mount on slides, but simply carded, The 

 insects dealt with here were all mounted on cards, and the names over 

 which they stand in our collections have been accepted as correct; they 

 were all uniformly mounted, and in many eases bear data in what appeal's 

 to be Walker's handwriting, while the number of specimens, as a rule, 

 agrees with that which he gives in his Catalogue as being present in the 

 British Museum. An examination of this material reveals the fact that 

 we have re])resentatives of three genera described in the last few years, 

 one from Africa, the other two from America, present in this country. 



Atheroides serrulafus Halid. 



Apterous Male. — In my paper ou the genus Atheroides (Ent. Mo. 

 Mag. Feb. 1920) I omitted any reference to the apterous male. This 

 resembles the apterous female in shape and disposition of spines very 

 closely, but is considerably smaller, being but I'Smm. long by 0-4 ram. 

 broad. Segment III of the antennae has about 25 sensoria, giving it a 

 distinctly tuberculate appearance, while IV has about 10 ; the proportions 

 of the segments are 30, 17, 70, ^'j (2G-}--jO) (fig. 1, F).
