 and forward. ? : Inst ventral segment pentagonal, the distal half produced

repens butleri, n. s. 



The dorsum of the elytra is often suffusedly fuscous in smaragdula, but I have 

 not found the claval suture fuscous in either populi or butleri. 



With regard to the application of the name smaragdula, Fallen's 

 original description (Hem. Suec. ii, p. 53, 46) is not very conclusive, 

 but I think that the phrase " In aln 'tibus . . . sat frequens " 

 leaves little room for doubt that the insect which I have called 

 smaragdula was intended ; neither populi nor butleri would be found 

 on alder except by accident. Moreover, the description of the last 

 ventral segment in the female given by Flor, Sahlberj;, Kirschbaum, 

 Fieber, and Melichar evidently refers to the species here called 

 smaragdula, Fall. 



ClILOIUTA APICALIS, Flor. 



1 now think that this species should not be expunged from our 

 list. It is true that Marshall's material standing under that name in 

 1887, when he was good enough to send it for me to see, did not 

 comprise a specimen of it ; but having regard to the shipwreck of 

 his collections several years before, it is nearly certain that the 

 specimens in question did not include the insects which he had before 

 him when writing on the group twenty years previously ; and, more- 

 over, he had not then for many years concerned himself actively 

 with the Auclienorhyncha. I have never seen an example of this 

 species, British or otherwise, but it should be easily recognised by 

 the dark smoke-coloured membrane. Flor says that it is found at 

 the end of July and beginning of August on limes and elms. 



Chloeita solani-tuberosi, Koll. 



By beating spruce firs and other conifers in winter one obtains 

 two kinds of Ghlorita, both having the suprabrachial area of the elytra 

 hyaline throughout, and the white silky hairs on the apex of the 

 male genital plates twice as long as the bristles on the other parts of 

 the plates, but quite distinct in colour and habitus when alive or 

 recently dead. One is a little the larger and more robust-looking, of 

 a blue-green (that of a leek leaf), with the crown more broadly 

 rounded in front, and should be called Jlavescens, Fabr. ; the other is 

 comparatively smaller and more slender, of a yellow-green (that of an
