JIrl(qjhoru.^.] IIVDROPIIILI[).E. 239 



H. 3>Iulsanti, Rye. {<Iorsalis, Mnls., ncc Marsh). Oblong ; head 

 and thorax bronze green or coppery, iridescent, tlie latter with the sides 

 often paler ; internal furroAvs of thorax sinuous ; alternate interstices 

 of elytra slightly raised : this species somewhat resembles //. hrevipalpis, 

 from which it may be distinguished by its slender palpi and larger size ; 

 from light specimens of //. icnerpennis the sinuous internal furrows of 

 thorax will separate it ; Avhile from //. affinls it differs entirely in size, 

 shape, and sculpture; from all three the slightly raised interstices of 

 elytra will distinguish it ; the underside is hardly pubescent ; legs 

 testaceous. L. 3|— i mm. 



Local; not micomnion near London, Lcc, Chatham, Rainham, Darcnth Woori, 

 Dorking', Winibleilon, Mickleham, Earlswood ; Lvmington Salterns ; Liverpool (rakeii 

 commonly by Ci'otch) ; Scotlanii, local ; abundant in pools of salt water by the side 

 of the Kith below Dumfries, but not recorded from any other locality. 



H. affinls, jNfarsh {Erichsoni, Bach., don^alis, Er., griseu)<, Thoms.). 

 One of our smallest species ; head and thorax usually very strongly 

 metallic, bright green or bright red, the latter almost smooth on disc ; 

 antennse and palpi yellow- testaceous, tip of last joint of latter sometimes 

 dark ; elytra ligliter or darker testaceous with dark markings distinct, 

 punctured stj-ise not very strong, interstices broad and flat; legs testa- 

 ceous. L. 2-3 mm. 



This species does not appear to be nearly as common as 11. hrevipalpis, 

 with which it appears to be mixed in collections. Dr. Sharp considers 

 that it is doubtful whether it occurs at all in Scotland : it may easily be 

 distinguished from H. hrevipalpis by the elongate last joint of the nuixil- 

 lary palpi, and in a less degree by the broader and flatter interstices of 

 the elytra ; in this latter point, however, it is somewhat variable. In 

 ]\lr. Matthews' collection there is a large specimen 4 mm. in length. 



K. brevicollis, Thoms, (gram/Iaris, L. 1, griseus, Ilerbst. '?). This 

 is a somewhat doubtful species; it closely resembles the preceding, but 

 tlie elytra are somewhat narrower, more parallel-sided, and more pointed 

 at apex ; the disc of the thorax is distinctly granulated, and not smooth 

 or nearly smooth as in the preceding species ; the interstices of the elytra 

 are narroAver and more convex ; ironi the succeeding species it is distin- 

 guished by the elongate last joint of the maxillary jialpi. L. 2-2.'. mm. 



Rare; two specimens recorded by Mr. Blackburn from Killarney, and two in Dr. 

 Power's collection from the London district that seem to agree witli a type specinuu 

 sent me h\ M. Ikdel, are all that 1 know of, but it is veiy likely mixed "with the pre- 

 cedini,' in many culleL-tions. 



H. brevipalpis, Jledel {(jrixnis, Er., grcoinJaris, Thoms.). Colour 

 latlier variable ; head and thorax iridescent, but sometimes dull ; 

 anteun.T and palpi testaceous or more or less dark, last joint of latter 

 dilated at base, not elongate; thorax granidate on disc as Avell as at 

 sides ; elytra lighter or darker testaceous with dark markings jilainly 

 visible, with rather strong punctured striae, interstices not broad and 

 slightly convex ; legs brownish testaceous. L. 2-2 j mm. 



Common and widely distributed throughout the kingdom.
