parallel, less depressed, punctuation move fine; from H. melano- 

 cephalus by its form, not parallel, less elongated, smaller size and 

 pubescent elytra. France.) 



(H. nivalis, Heer., Fairmaire. Long. 3 — 4. Much resembles 

 H. nigrita and H. melanocephalus ; differs from H. nigrita by its 

 larger size, more elongated form, suture always punctate at base, 

 head black, legs more obscure; differs from H. melanocephalus 

 by its smaller head, thorax uniform in punctuation, elytra not 

 parallel, their sides somewhat broader at base than base of thorax. 

 France.) 



28. H. erythrocephalus, Linn., Fab., GylL, Aube. H. deplanatus, 

 GylL, Aube, var. $. One of our most common species. Long. 4j; 

 larg. 2i. 



(H. vagepictus, Fairm. Long. 4. Much resembles H. erythro- 

 cephalus, more convex, more narrow behind ; thorax forms with base 

 of the elytra a more distinct angle ; lateral band of elytra larger and 

 more distinct: differs from H. rnfifrons by its more oval form, less 

 parallel sides of elytra, bead larger, thorax less narrowed in front, 

 punctuation not so deep, and by the angle of thorax with sides of 

 elytra. France.) 



29. H. rufifrons, Dufts., GylL, Sturm. H. piceus, Steph. I have 

 taken this species in the Huntingdonshire Fens and near Cambridge : 

 it is by no means common : Norfolk ; Berwickshire, rare ; occasionally 

 near Paisley. Long. 5 ; larg. 2j. 



30. H. oblongus, Steph. H. nitidus, Sturm, Erich., Aube. This 

 insect is to be taken in abundance only in the very early spring, or 

 even before spring has appeared : I took it very sparingly round 

 Horning, Norfolk, in May, 1854. Long. 4 J ; larg. 2j. 



31. H. ferrugineus, Steph. H. victor, Aube. Long. 4 ; larg. 2. 

 The only known localities for this species are near Collingbourne 

 Wood, once in 1828, and several in a stream at Kimpton during the 

 spring of 1829: it resembles H. memnonius, but has thorax more 

 rounded at sides, is more parallel in form. It is taken in France, 

 Constance, &c. 



32. H. melanarius, Sturm, Erich. Long. 3f; larg. 2. Resembles 

 somewhat H. melanocephalus, Gyll.,h\\i may be distinguished at once 

 by its more parallel sides ; head and thorax decidedly larger, elytra 

 continuing exactly the line of the thorax, and covered with deeper and 

 more distinct punctuation ; colour more brilliant black ; legs and an- 

 tennae entirely ferruginous. I took two examples of this insect in 

 Horning Fen, 1854.
