of base. Elytra fully striate (as in Th. tnsmanicus, Bates); second 

 interstice not striolate at base, third unipunctate behind the 

 middle. Anterior tarsi of $ with joints 2-4 widely dilatate, 

 intermediate tarsi with joints 2-4 lightly dilatate. Length 4-5, 

 breadth 1'6 mm. 



Hab. : Victoria — Mordialloc, near Melbourne (French). 



Allied ti) Th. tnsmanicus, Bates, from which it is readily 

 differentiated by its black head. A species which seems certainly 

 Til. tasmanicns, Bates, is widely distiibuted in South Eastern 

 Australia, and comparing Th. bicolor with that species the follow- 

 ing differences are noted apart from colour : — prothorax shorter, 

 with posterior angles far less strongly marked and more obtuse, 

 the basal puncturation much finer and less conspicuous. From 

 Til. ausiralis, Blkb., it offers the following evident differences : — 

 size larger, form wider; anterior tarsi of ^ dilatate; elytra fully 

 striate, the base reddish right across, the black discoidal areas 

 extending to the margin at sides, ttc. 



Thenarotes tachioides, n.sp. 



Subconvex; head short, lightly biimpressed between base of 

 antennse ; mandibles short, hardly projecting Ijeyond labrum ; 

 prothorax concavely impressed on each side of base, basal angles 

 subrectangular; elytra fully striate, second interstice not striolate 

 at base, third interstice unipunctate about apical third; posterior 

 tarsi with first joint about as lung as two succeeding joints 

 together. Testaceous-brown, nitid; elytra more or less clouded 

 with black; head black, antennae infuscate; inflexed margin of 

 elytra, labrum, palpi and basal joint of antennae pale testaceous; 

 under surface of body piceous, becoming testaceous towards apex 

 (two apical ventral segments); prosternum brownish-testaceous. 



Head wide, convex, a short, light, oblique impression on each 

 side of front; eyes large, lightly inclosed at base. Prothorax 

 transverse (0-7 x 1 mm.), widest before middle, a little narrowed 

 to base, wider across base than apex, widely and lightly convex 

 on disc, depressed near base; margins explanate near basal angles; 

 sides bordex'ed, lightly rounded on anterior two-thirds, very lightly 

 oblique posteriorly; anterior margin truncate, angles obtuse; base
