Hy. fuscipes. LinnL—Mart. C. pi. 33. /. 15.— Hy. fuscipes. Steph. Catal. 

 p. 60. No. 604. 



Shorter but scarcely narrower than the last : oval, pitchy-black, thickly but not 

 very coarsely punctulate, with some larger impressions on the head, and on 

 the sides of the thorax : elytra rather faintly punctate-striate, the interstices 

 thickly and finely punctulated, the alternate ones with some deeper impres- 

 sions : body beneath dull black : legs piceous, with the tarsi rufescent : palpi 

 ferruginous : antennae with the club black. 



Var. /?. With the legs pale rufo-testaceous, the base of the femora dusky. 



Common in every pond and collection of water throughout the 

 metropolitan district. " Southend and Kensington-gardens." — 

 Rev. F. W. Hope. " Bristol."— Dr. Leach « GlanviUVs Wootton, 

 and Scotland." — J. C. Dale, Esq. 



Sp. 3. chalconotus. Ovalis, cupreo- aut aeneo-niger, vel splendide viridi-osneus, 

 vage punctatus, elytris subcrenato-striatis, pedibus piceo-testaceis, tarsis dilu- 

 tioribus. (Long. corp. 3—3^ lin.) 



Hy. chalconotus. Leach MSS. Steph. Catal p. 60. No. 605. 



More coarsely punctured than the last : colour very variable, coppery or brassy- 

 black, or of a splendid greenish-brass, sometimes violaceous or bright green : 

 head and thorax as in the preceding, but the punctures deeper : elytra more 

 deeply striate, the striae slightly crenulate : legs pitchy-testaceous, with the 

 tarsi paler, and the base of the femora dusky. 



The difference in sculpture, and usually brilliant metallic colouring, discriminates 

 this from the foregoing insect. 



Also very common throughout the metropolitan district, and I 

 believe in other parts. " Spitchweek, Devonshire." — Dr. Leach. 

 " Bottisham." — Rev. L. Jenyns. 



Sp. 4. subrotundus. Brevis, subglobosus, nigro-piceus, vage et creberrime punc- 

 tatus, elytris prqfunde punctato-striatis, pedibus nigro-piceis. (Long. corp. 

 2^—2} lin.) 



Hy. subrotundus mihi. Steph. Catal. p. 60. No. 606. 



Short, subglobose, pitchy-black, coarsely and thickly punctate: elytra rather 

 deeply punctate-striate, the interstices alternately with deeper impressions: 

 body beneath dull black : legs pitchy-black. 



The inferior size and short subglobose form, with the coarseness of the sculp- 

 ture, distinguish this from all the preceding species. 



Found near London by myself ; I also obtained one specimen 

 from the Marshamian Cabinet.
