(5) The " plcDiicejys group" though spread from the Gulf of 

 Carpentaria to Bass Strait, is probably of tropical origin; it has 

 not yet been reported from the western half of the continent. 



(6) C. grandiceps is from the neighl)ourhood of Burketown on 

 the Gulf of Carpentaria. 



(7) The " punctaticeps grotip " (4 species ! is evidently a tropical 

 group with one species, C. adelaida, in the Murray River water- 

 shed. 



(8) C. hlackburni is from Lake Callabonna in Central Australia. 



(9) C. olHffi is from West Australia. 



(10) The " heterogena group" (9 species) has representatives 

 already reported from most parts of Australia, though none is yet 

 known from West Australia, south of the tropics. 



(11) C. bovillcH seems to have a -svide distribution along the 

 northern coastal region. 



(12) The " australasia; group" (27 species) is spread over the 

 whole continent. I haxe further divided it into four sections^ of 

 these — SecUon I. (type, C. sellata, Putz. — 8 species) apparently 

 belongs to eastern Australia, and seems to be of tropical origin. 

 Section II. (type C. austrcdasia\ Bohem. — 6 species) is of eastern 

 origin, though now found over the greater part of the continent; 

 it also has a representative in New Zealand and Lord Howe 

 Island. Sectio7i III. (type C. bascdis, Ch. — 12 species) is spread 

 over all Australia and Tasmania, and has a species in New 

 Zealand. Section IV., founded for C. pectorcdis. is undoubtedly a 

 tropical type. 



(13) The " procera group" (15 species) has its headquarters on 

 Eastern Australia. It may be divided into seven sections, of 

 which six have repi*esentatives in tropical Australia. 



The members of the genus Clivina are strong fliers; often in 

 summer evenings they may be noticed flying to the lamps in 

 lighted rooms. All the species are found in damp ground near 

 the margins of rivers, marshes, ponds, or, indeed, any tolerably 

 permanent water; their habits are fossorial. Some species may 

 be found all the year round, though more rarely in the winter
