BY THOMAS G. SLOANE. 193 



terorum Europae (1906) 23 subgeneric names are recognised among the 174 

 species there recorded, of which only Philocthus appears in our fauna; Netolitzky 

 in 1914 proposed a subgenus Notaphocampa founded on B. niloticum Dej., into 

 which B. opidentum Niet. will come.* 



Blackburn published a table including all the Australian species (Trans. 

 Roy. See. S. Aust., 1901, p. 122), which is merely an aid in the identification 

 of the species; T therefore venture to offer the following table to indicate the 

 natural groups among our species. 



Table of Australian species known to me. 



1 (4) Frontal sulci shallow, not crossing clypeus, interspace depressed. 



2 (3) Prothorax cordate, sides sinuate posteriorly, lateral margin narrow, base 



a little arcuate, lightly oblique on each side opulcntum Niet. 



3 (2) Prothorax transverse, rounded on sides, lateral margin wide, base shortly 



sublobate. strongly sinuate on each side jacksoniense Guer. 



4 (1.1 Frontal sulci deep, crossing clypeus, interspace convex. 



5 (6) Elytra with third and fifth interstices bearing fixed setae 



proprium Blackb. 



6 (5) Elytra with discal fixed setae only on third interstice. 



7 ',8) Elytra with seven inner striae present duiium Blackb. 



S (7) Elytra with six inner striae present errmis Blackb. 



B. hobarti Blackb. (Tasmania) and B. u-altsenee Blackb. (from the Watts 

 River, a tributary of the Yana) are unknown to me in nature; both are evi- 

 dently species distinct from one another and from all our other species. B. 

 hobarti has the seventh stria perceptible; it may be allied either to B. pro- 

 prium or B. d/iibium, though it is not likely to have fixed setae on the fifth inter- 

 stice. B. wattsense, having only the five inner striae marked, is thus differen- 

 tiated from all the other Australian species known. 



Bembidion opulentum Nietner. 



Ann. Mag. Nat. Hist., (3), ii., 1858, p. 420; Andrewes, Ann. Mag. Nat. 

 Hist., (9), iii., 1919, p. 472; Sloane, Proc. Linn. Soe. N.S. Wales, xlv., 1920, 

 p. 321.— jB. europs, Bates, Ann. Mag. Nat. Hist., (5), xvii., 1886, p. 156.— B. 

 riverinae, Sloane, Proc. Linn. Soc. N.S. Wales, (2), ix.. 1894, p. 405. 



I believe the synonymy given above to be correct; probably B. hamiferum 

 Fauvel (1882) from New Caledonia will prove to be the same species. 



Hab. — Australia, Sumbawa, Java. Ceylon, India. Beside fresh water. 



Note. — It has been found in Queensland, New South Wales, and Victoria, 

 but I have not seen it from South Australia or Western Australia. 



Bembidion jacksoniense Guerin. 



Voy. Coquille, 1830, p. 61, PL i., flg. 17; Sloane, Proc. Linn. Soc. N.S. 

 Wales, (2), ix., 1894, p. 406. — Bembidium subviride, Maeleay, Trans. Ent. Soc. 

 N.S. Wales, ii., 1871, p. 118.— S. ocellatum, Blackburn, Trans. Rov. Soc. S. 

 Aust., X., 1886-87 (1888), p. 44; Proc. Linn. Soc. N.S. Wales, (2). "vii., 1892, 

 p. 98. 



This species seems to be found over the whole continent of Australia beside 

 fresh water. 



*I have not seen any of the numerous memoirs on the tribe Bembidiini pub- 

 lished by Dr. Netolitzkv in recent vears.
