2 78 FAUNA HAVVAIIENSIS 



Bembidium Latreille. 



This is an enormous genus, and as regards exotic forms is but little known. 

 Its European members have however been extensively studied and distributed in 

 numerous subgenera. Mr Blackburn placed two of the Hawaiian species in the 

 European subgenera Notapkus and LopJia. But I cannot follow him in this course. 

 One of our species, B. teres, comes sufficiently near to the subgenus Synechosiicius to 

 warrant its location there. A second species, B. pacificzini, comes near to B. nor- 

 mannuin of the subgenus Emphanes, and I associate it therewith and accompany it 

 with a second species that appears to me to be closely allied. B. ignicola Blackburn, is 

 perhaps allied. 



Though I place Bcmbidiuni advena here, it has but little relation to any of the 

 others. Only one specimen of it has been found, and I expect that when it can be 

 investigated it will be found to form another peculiar, possibly flightless genus, 

 allied to Nesocidium. This insect has not the peculiarity of the head I refer to in 

 connection with B. pacificum, and at present may be treated as more allied to B. 

 (Synechost ictus) teres.

Bembidixivi [Lopka) teres Blackburn, Ent. Mo. Mag. xvii. 1881, p. 229. 



This species has remarkably flat elytra ; this, in conjunction with the normally 

 short trophi, the striate elytra, and the thorax strongly narrowed behind, will lead 

 to its identification. The length is about 5 mm. 



Hab. Kauai, Oahu, Molokai, Maui; apparently scarce (Blackburn, Perkins). 



(2) Bembidium [Synec/iost ictus ?) adt'eiia, sp. no v. 



Subdepressum, fusco-aeneum, antennis nigris, basi, palpis, pedibus elytrisque flavis, 

 his nigro-pictis. Long. 3^ mm. 



Plate VII. fig. 19. 



Antennae dark, with the first two joints and base of the third yellow. Head very 

 short, eyes moderate, frontal grooves quite parallel, intra-orbital setae approximate, the 

 surface dull metallic. Thorax transverse, greatly narrowed behind, so that the base is 

 narrow, the surface golden, with a peculiar very fine sculpture, a sort of chasing, making 

 it dull, except in the middle where it is a little shining'. The median channel distinct. 

 Elytra not elongate, rather parallel-sided, the shoulders obliquely rounded, the disc ver\- 

 distinctly quadrifoveolate ; each with seven well-marked striae, continued to near the 

 tip, with faint indications of punctuation, the very fine lateral margin is black, and there 

 is an angular patch of dark purple-black colour at each side, and a transverse, black, 

 common one before the apex. Legs pale yellow. Male with two basal joints of front 

 tarsi dilated, and spinose at the interno-anterior angle. One specimen. 



Hab. Maui. Haleakala, 5000 ft., April 1894 (Perkins).
