This genus now contains about fifty apparently valid species recorded from all 

 portions of the world. They are very clo.sely related among themselves and their 

 separation i.s correspondingly difficult. t)nc of the nio.st satisfactory characters, in 

 the wTiter's exjDerience, for the difl'erentiation of closely alUed forms is the presence 

 or absence of the sense-cone on the inner surface ot the apex of the third antennal 

 segment. In the critical examination of several thousand specimens of this genus, 

 this character ha.s been found absolutely constant, and in the following key it is used 

 for the primary division of the genus. 



Before i)roceeding with the synopsis and discussion of the Australian species 

 of Ila/ilol/iri /jfi. it may be well to comment briefly on one of the papers cited above, 

 namely, Mr. Watson"s recent contribution to " Entomological News." On examina- 

 tion of this paper, it will be seen that the author has failed to employ the i)roper 

 generic lerm for this genus, and has used instead a name winch for four years had 

 reposed in synonymy. In addition he adopts, in his key to six North American species, 

 four synonymous names, while five additional North American species are completely 

 overlooked. 1'he new sjoeeies described is a synonym of one characterised four jcars 

 previously by the present writer. The corrected list of North American species, 

 after adding one published since the appearance of Wat.son's paper, is as follows : —
