the male nabellum of the species before me). It is also 

 notable in respect of the inner spur of its hind tibiae, which 

 is dilated from its base in the male to beyond the middle of 

 its length (and then suddenly narrowed almost to a point) 

 and in the female quite to its rounded apex. 



I must defer the description of this insect as a species 

 until my next paper, as a memoir by Herr Brenske describing 

 new species of Lepidoderma (among which it is just possible 

 that this species is included) will not reach me until too late 

 to be studied before the issue of my present paper, but it 

 seemed desirable to place the genus in the preceding tabu- 

 lation. 



PARARIIOPiEA (gen. nov. M ' elolonthidarum verarum, 



Lac). 

 Mhopcece affinis. Mentum transversum ; palpi labiales minus 

 breves, articulo apicali oblongo ad apicem acuminate; 

 palpi maxillares sat elongati, articulo apicali supra con- 

 cavo ; labrum sat magnum fere horizon tale, antice pro- 

 funde emarginatum ; clypeus modicus, declivitate antica 

 alta verticali aequaliter rugulosa et pilis sat elongatis 

 obsita : antennae 10-articulatae, flabello maris valde 

 elongato (hujus laminae quam tres sunt plures) ; pedes 

 sat elongati, tibiis anticis intus ad apicem spina brevi 

 armatis extus dentatis, tibiis posticis maris ad apicem 

 calcaribus 2 armatis (horum altero brevi spiniformi altero 

 elongato laminiformi a basi ad mediam partem leviter 

 dilatato), unguiculis pone medium dente valido armatis 

 ad basin vix dentiformibus. 

 Femina latet. 



Ad hoc genus tribuenda est P. (Rhopcea) callabonensis, 

 Blackb. 



This species has been sufficiently described in Trans. 

 Roy. Soc, S.A., 1894, p. 205. It should perhaps be added 

 that its front tibiae have three external teeth. It differs from 

 Ehopcea principally by the form of its labrum, by the more 

 elongate and slender apical joint of its labial palpi, and by 

 the spurs of its hind tibiae.

 ANTITROGUS. 

 All the specimens that I have seen of this genus are 

 from the south-eastern quarter of Australia and from Tas- 

 mania. Examples, especially of the female, are not common 

 in collections, but this is due probably (at any rate in respect 

 of the males) to accidental circumstances, or perhaps to 

 periodicity, as males of one of the species known to me were
