Head of moderate size (2 x 2-2 min.), smooth; frontal impres- 

 sions small, light, clypeal suture distinct between them; eyes not 

 prominent, convex; orbits a little convex behind eyes. Prothorax 

 depressed, lightly declivous on sides anteriorly, explanate near 

 basal angles, subquadrate (3-2 x 4-7 mm.), widest at marginal 

 puncture (about middle), wider across base than apex ; sides 

 lightly rounded, lightly and obliquely narrowed posteriorly, 

 strongly and roundly narrowed anteriorly; anterior margin deeply 

 emarginate; base truncate; anterior angles prominent, obtuse; 

 basal angles widely obtuse ; border narrow, wanting only on 

 middle of anterior margin; lateral basal fovese lightly impressed, 

 feebly punctate. Elytra depressed, wider than prothorax 

 (8-5 X 5-5 mm.), subparallel on sides, vexy feebly sinuate on each 

 side of apex; striae linear, strongly impressed; striole at base of 

 second interstice elongate ; interstices subopaque, shagreened, 

 depressed but becoming convex near apex (especially interstices 

 6-8), third and fifth with finely impressed widely placed punctures 

 along their course. Length 14-14-5, breadth 5-5-5 -8 mm. 



Hal. : jSTorth Queensland (sent to me by Mr. C. French as from 

 the Winton District, N.Q.). 



A distinct species which may be readily distinguished from its 

 nearest allies Gn. latm, SI., and Gn. rii'erince, SI., by its more 

 depressed form, the pluripunctate fifth interstice of elytra, etc. 



PsiLONOTHUs, n.gen. 



Head smooth, wide, convex; front not impressed; eyes small, 

 distant from buccal fissure beneath. Mandibles short. Mentum 

 deeply emarginate; sinus edentate, oblique on each side. Palpi : 

 maxillai-y stout, two apical joints together oval and pointed; 

 labial thick, penultimate joint short with two setae in front, apical 

 joint short, swollen. Metasternal episterna (without epimera) 

 subquadrate. Fades robust, short, convex. Apterous; elytra 

 connate. Anterior tarsi of $ not dilatate or clothed beneath. 



The position of this genus among the Australian Harpalini is 

 near Thenarotidius. It is distinguished at once from iVotophilus 

 and allied genera by the eyes being distant from the buccal fissure
