from Victoria, though a specimen is in my collection labelled 

 "Victoria." but on what authority I do not know; my not having 

 seen it from near Melbourne is no evidence that it does not occur 

 there. 



Thenarotidius, n.gen. 



Head smooth, front not impressed. Eyes round, convex, 

 coarsely faceted, distant from liuccal fissure beneath. 



MandihJes short, stout. 



Ligida small, narrowed to apex, corneous; apex obtuse, bisetose; 

 paraglossaj membranous, wide, subquadrate, extending consider- 

 ably in front of ligula, connate in front of ligula. 



Menlum concave; sinus bordered, oblique on each side, evenly 

 rounded (edentate) in middle. 



Palpi : maxillary with apical joint fusiform, longer than pen- 

 ultimate; labial short, stout, two terminal joints of equal length, 

 apical joint thick, obtuse at apex, finely and sparsely setose. 



Prothorax transverse, not impressed or punctate on each side 

 of base; marginal setigerous puncture rather large, placed about 

 middle of length. 



Elytra lightly striate; eighth stria obsolete in middle; inter- 

 stices shagreened and finely punctate, third finely unipunctate 

 about apical fifth. 



Metaslernum with episterna narrow, elongate. 



Legs light : ^ with four anterior tarsi lightly dilatate, four 

 basal joints densely clothed with spongiose tissue beneath. 

 Posterior tarsi linear, hai'dly as long as tibiae, first joint nearly as 

 long as two succeeding ones together. 



Apterous: body shortly pedunculate; upper surface shagreened. 



The type of this genus is Th. gagatiniis, Macl., a species which 

 was described as belonging to the genus Bemhidium; it is common 

 in many parts of N.S. Wales. Thenarotidius may be readily 

 recognised among the Australian Harpalids byits narrow depressed 

 form, coal-black colour and ej^es distant from mouth beneath. 

 The penultimate joint of the labial palps appears to have only 

 two setfe in front, but a careful examination of the palps removed
