ciably widened in front. The sculpture of the dorsal interstices of 

 the thorax is somewhat less strong than that of the intermediate and 

 lateral ones, but evidently stronger than in viridicollis. The dorsal 

 interstices of the thorax are obliquely impressed near their basal 

 third, and the inner part of their apical two-thirds is gently excavated 

 towards the central channel and thus forms a distinct subelliptic 

 impression ; this character, however, is frequently met with in speci- 

 mens which are obviously nothing but viridicollis, and may be in the 

 example before me only an individual peculiarity. These particulars 

 are taken from a specimen kindly lent to me by Mr. Champion and 

 labelled " Pommern, Goeslin Liillwitz." Our information with regard 

 to this species remains praencally where Blackburn (I.e.) left it in 

 18/6 ; to him it appeared to be not uncommon in Scotland and 

 Ireland, but he had not seen any English examples. 1 have seen no 

 British specimens of it, nor have 1 met with any fresh record of its 

 occurrence in this country. 



[I. laticollis, Thorns. —I have taken this species at Horning, and 

 have specimens from Woking ex coll. Champion. 



H. nanus, Sturm. — Occurs very sparingly in the Colesborne 

 district ; well-marked examples are conspicuous in the water-net by 

 reason of the dark parallellogram common to both elytra. 



The circumstantial account of it given by Blackburn (I.e.) 

 renders necessary some notice ot 11. planicollis, Thorns. Ganglbaucr 

 treats it as a synonym of viridicollis. I have not seen any specimen 

 possessing the characters laid down for it, and therefore transcribe 

 the material part of Thomson's diagnosis. " H. ceneipenni statura et 

 magnitudine simillimus, prothorace longitudinaliter baud convexo, 

 lateribus par urn rotundatis, elytris minus fortiter punctato-striatis, 

 interstitiis ajqualibus angustioribus, femoribus basi nigro-fuscis dis- 

 tinctus." 



In the catalogue of British Coleoptern bearing the names of 

 Messrs. Beare and Donisthorpe, obscurus, Muls., is introduced as 

 a distinct species under a separate number with v. shetlandicus, but 

 the better opinion seems to be that obscurus, Muls., is the same as 

 viridicollis, Steph. Kuwert's name was given to specimens from the 

 Shetlands with black metallic shining elytra.
