H. CORYLI, All. — This is our well-known, bright metallic-green, hazel-frequenting 

 species ; I retain Allard's name for this insect, notwithstanding that Weise puts it 

 as a var. of H. qiiercetorum, Foudr. (distinguished therefrom by the want of a 

 lateral fold on the elytra), because it has long been known to us under the name of 

 coryli, which is, moreover, very appropriate. It is also the insect described by 

 Fowler (Col. Brit. Islands, iv, 358), under the name of ampelophaga, Gruor. ; his 

 opinion that all our specimens (pi'csumably of the insect described by him) must be 

 referred to H. oleracea, apparently arises from the fact that a pair of specimens 

 standing under the name of ampelophaga in Dr. Power's collection, and labelled 

 ohracea by Reitter, undoubtedly belong to the species so long known to us as 11. 

 coryli, and hare nothing to do with H. oleracea, L., as understood and defined by 

 Weise. The widening of the elytra behind is more distinct in the females than in 

 the males, but the species can scarcely be confounded with anything but ericeti, 

 from which it may be easily distinguished by its habitat, and its distinctly depressed 

 form. There are several European species of a bright metallic-green colour, but the 

 form of the cedeagus would serve to distinguish them. The true anipelophaga, Gruer., 

 which, according to Weise, = cowsoirina, Foudr , may, perhaps, be found here some 

 day, since the latter author's insect is found on sallows, particularly on dwarf sallows, 

 as well as on the vine. 



H. iTTHRi, Aube. — This is the H. consobrlna of our collections ; in form it is 

 (normally) even more depressed and widened behind than H. coryli ; in colour dark 

 blue, with a greater tendency to acquire a violet than a greenish tinge, and the 

 punctuation is, as a rule, very fine. Blue-green examples of this species a trifle 

 more convex in appearance, and having the punctuation a little more evident than 

 usual are the tamaricis of Fowler, but not of Schrank. After a careful examination 

 of thirteen specimens of this kind (twelve 9 , one <?), I cannot discover any satis- 

 factory cliaracter or characters by which to separate them from H. lytliri ; the form 

 of the (hdeagus is practically the same as in that species. In defining H. tamaricis, 

 Schr., Weise makes a great point of its narrow thorax, which he says is about half as 

 wide as the elytra at the shoulders : of course, one docs not expect mathematical 

 precision in comparative measurements of this kind, but, of the four specimens from 

 Dr. Power's collection lent to me by Fowler, not one has even the appearance of 

 possessing an abnormally narrow thorax ; one of these specimens, labelled tamaricis 

 by Reitter, measures "07 in. across the base of the thorax, and "09 in. across the 

 shoulders of the elytra, and exactly the same relative proportions obtain in the other 

 three, although in one of them the measurements are '06 in. and .08 in. respectively. 

 Weise records H. tamaricis, Schr., as inhabiting England ; apparently on the 

 assumption that Stephens' Haltica erucce is synonymous. He also tells us that 

 tamaricis, Schr., is synonymous with the hippophaes of Foudras, and as the latter 

 lives on Hippopha'e rhamnoides, L., it may possibly yet be found in Britain on that 

 plant, if not on Tamarix gallica, L., a plant common enough on our sandy coasts, 

 although not indigenous. 



H. EEiCETi, All. — This is a convex, parallel-sided species, generally blue-green 

 or green in colour, which sometimes swarms on Calluna and Erica ; it is not, how- 

 ever, the only species whieli occur- on Erica, for on the only occasion that I have 

 yet found H. oleracea, L., in quantity it was on Erica tetralix on Household Heath.
