(3) Beiubidutm {Emp/iancs) pacificnin, Blackburn. 



Bembidhmi i^Lopha) pacific inn Blackburn, Ent. Mo. Mag. xv. 1878, p. 157. 



This species is of a brass)- colour abov^e, with yellow marks on the elytra. It 

 is readily distinguished from Syncchostictns by the deep clypeal suture which causes 

 the front part of the upper surface of the head to look much more uneven. I have 

 seen only half a dozen examples. 



It would not be difficult to imagine this species to be the progenitor of B. iiioio- 

 kaiensc, and the allied forms of N^esocidiuin. 



Hab. Kauai, Oahu. " Oahu, not rare, but very local, though found in several 

 localities ; it generally occurs running on damp ground" (Blackburn). Kauai, Mountains, 

 Waimea, 4000 ft., May 1S94 (Perkins). 



(4) Benibidinui {Eiupharics) ij^iu'co/a, Blackburn. 



Boubidiini! ignicola Blackburn, Ent. Mo. Mag. x\i. 1879, P- I09- 



I have seen only the specimen in the British Museum, Mr Blackburn's type. It 



apparently comes somew^hat near both B. pacificiini and B. molokaiensc. It is smaller 



and darker than B. pacificnm and very deeply sculptured. 



Hab. Hawaii. One specimen, Kilauea ; " I almost burned my fingers in 

 securing it" (Blackburn). 



(5) Bembidiuin [Emphanes) nmlokaiciisc, sp. nov. 



Nigrum, supra plus minusve viricii-micans, antennarum basi pedibusque rufo-testa- 

 ceis, antennis extrorsum fuscescentibus ; prothorace transverso : elytris versus basin 

 subplanatis, ibidemque late bi-impressis ; fortiter seriatim punctatis, dimidio apicali im- 

 punctato, perpolito. Long. 2| — 3 mm. 



Plate VII. fig. 23, wing. 



Variable. Like Nesocidium lacticulum, but possessing perfectly developed wings ; 

 in addition to this none of the examples from Molokai agree with that species, which is 

 a native of Kauai. The shape is slightly narrower and more elongate, the colour 

 less brilliant, and the punctures in the striae a little smaller, so that there are generally 

 12 or 13 in the outer or subhumeral one : this is however variable and of little importance, 

 but the more elongate after-body enables most of the specimens before me to be 

 distinguished from N. laeticuluvi. 



I have examined the wings (Plate VII. fig. 23) in nearly all the eighteen individuals. 

 They are constant in size, but appear to vary a little as regards the distinctness of the 

 nervures. A variety occurs in which there is a vague but large yellow patch on each 

 wing-case before the tip. Fourteen of the specimens I have seen were found on
