rather strongly rounded in front, and then with sides feebly 

 dilated to extreme base, median line fairly distinct on apical 

 half j but not traceable to base ; punctures much as on pre- 

 ceding species. Elytra parallel-sided to beyond the middle; 

 punctures and striae much as on preceding species. Length, 

 8 mm.

 Type (unique), I. 5752. 



In general appearance strikingly close to the preceding 

 species, but prothorax less transverse, more rounded in front, 

 sides less parallel and with hind angles diverging outwards, 

 median line less conspicuous in front, and not traceable to 

 base. The antennae are strikingly different, but they are 

 probably sexually variable in both ; the type of the present 

 species is probably a male. 



As T do not know hero* and victoriensis, they have been 

 excluded from the following table, but the former would be 

 associated with basaJis and the latter with concoJor.

 Dromoeolus thoracicus, Lea. 



The genus Nematodes was not recorded from Australia 

 in Masters' Catalogue, and Bonvouloir described major as 

 from Victoria, in the United States. This mistake has been 

 already pointed out by Fleutiaux (Ann. Soc. Ent. Beige, 

 1897, p. 257), who records it from Melbourne. The late 

 Rev. T. Blackburn has already noted that Dromoeolus thora- 

 cicus is a Nematodes, and I am now convinced that it is a 

 pure synonym of N . major. The species varies in length from 

 6 to 10 mm. Two specimens from Merimbula probably 

 belong to the species : they differ from the others before me 

 in being smaller (5-5^ mm.), much paler, and with the discal 

 impressions of the prouotum scarcely traceable.
