! plentiful in a uest o£ Bomhus lucoi^um, which he put into a tin, and 

 from them reared a large number of the perfect insect in the fol- 

 lowing spring. 



h. Antennae with last joint narrower than the penultimate. 



-E*. melina, Er.— Easily distinguished from the preceding, whicli it most closely 

 resembles, by its much stronger and less close punctuation, the black club of its an- 

 tennae, and its darker colour. Erichson says of this species that the " legs in both 

 sexes are simple." Thomson says that the " male has the intermediate tibice sinuate." 

 I have examined a number of specimens, and Dr. Power has kindly examined his 

 series for me, and all these have the intermediate tibiae simple : this is only one out 

 of many points on which authorities are found at variance in this genus. 



Length, 1^ lin. 



Found, like the preceding, in flowers, especially hawthorn, but 

 nuch rarer. Bowdon near Manchester, Wimbledon Common, Cater- 

 bam, Mickleham, Darenth, Amberley, Claygate, Holm Bush, Dulwich, 

 Bretby near Eeptou, &c. 



jE. silacea, Er. — The largest species of the genus ; flatter than the two prece- 

 ling species, with much wider and stronger margins to the thoi-ax ; sides of thorax 

 larrowed in front, contracted and almost sinuate just before posterior angles ; 

 )unctuation not so strong as in JS". melina, but stronger than in JE. cestiva ; antennae 

 inicolorous, last joint hardly narrower than the preceding ; apex of elytra truncate ; 

 dale with intermediate tibiae sinuate. Length, 2 lin. 



Very rare ; Mr. Champion has taken it at Aviemore at sap of 



)irch (Thomson considers it as exclusively attached to flowers) ; it has 



.Iso occurred at Braemar, and in a rotten birch stump at the foot of 



Jross Craig, near Camachgouran, Eannoch ; it seems to be exclusively 



northern species. 



B. Species strongly oblong ; anterior margin of thorax almost straight, or 

 feebly emarginate. 



a. Punctuation extremely fine, almost invisible. 



-£'. oblong a, Herbst. — A light coloured species, easily distinguished from the 

 •vo succeeding by its extremely fine and close punctuation ; side margins of thorax 

 ery distinct, especially in front ; sides of thorax more dilated in front than in the 

 ext two species, last joint of antennae distinctly narrower than penultimate ; male 

 ith intermediate tibiae sinuate. Length, 1^—1^ lin.

 i Uhd. pine, Mr. Eye. 



b. Punctuation distinct. 



-E". longula, Er.— Distinguished from the preceding by its stronger punctuation 



I dark, almost black, club of its antenna? ; and from E.florea by having the an- 



'■ margin of the thorax distinctly, though slightly, emarginate, by its rather
