ate. finely bordered ; anterior angles obtuse, not near neck; lateral border narrow; 

 lateral basal impressions wide, sliallow. Elytra oval (4.4 x 3.5 mm.) , eonve.x ; apical 

 "urve wide, a little sinuate at extremity of ninth interstice; sides a little narrowed 

 to base; bolder rather wide, reflexed; interstices depressed, third with two or three 

 fine punctures on disc. Met-episterna (without epimera) about as long as broad. 

 Leno-th. 7—8. breadth, 2.0— .3.5 mm. 



//(//a— -Mount Wellingion ("Summit," Lea). Ten specimens have been ex- 

 amined. Mr. Lea informed me it was found on trunks of trees. 



A distinct species differino; from all others described by the followinj;- charac- 

 ters in conjunction : colour black ; jirothorax rounded on sides, narrowly bordered ; 

 posterior margiiial seta wanting; in no other species of Amblfitelus known to me 

 does tins occur. Compared with .1. cnrttix Fabr.. the fourth .ioint of the tarsi is 

 less strongly bilobed.

It is a distingiiisliing character of this species to have the legs testaceous with 

 the middle part of the femora black; the lobes of the fourth joint of the tarsi are 

 equal. Length. 4.5 — 5.5 mm. 



Hub. — Cradle Mountain, Waratah (C'arter and Lea); King Is. ( Lea) A 

 large series of specimens was obtained by Messi-s. Carter and Lea. some of whicli 

 Mr. Lea recorded as found "on King William Pine."

A specimen (?) from Launceston, 0.5 ram. in h-ng-tli, with the sutural black 

 stripe of the elytra reaching the base. I cannot differentiate from the tyiiical form 

 of the mainland. Six other specimens (c?) are in the Simson collection, which, 

 though smaller (6 7 — 8.5 mm.), must be taken to be eonspecitic with the larger 

 specimen, from which they only differ by their smaller size; it would seem that 

 Tasmanian specimens of A. eurtiis are of smaller average size than those of the 

 mainland. 



Hub. — Launceston, Brighton (Sir)ison, No. 1368); Exeter (Carter). 



Var. vittata Motschulsky. — A numerous series of si)ecimens (16. c?, V.) in 

 the Simson collection seem to represent A. vittatus Motsch. ; these specimens only 

 differ from .1. curtus Fabr., by having the eighth interstice black, as well as the 

 sixth and seventh, leaving only a narrow testaceous margin — the ninth interstice. 

 It is doubtful whether this slight colour variety is deserving of a varietal name. 

 Length. 8.5 — 11 mm.

 fissure beneath. Labrum truncate, 6-setose. Clypeus with a setiger(5us foveiform 

 puncture on each side. Mandibles stout, hooked, a seta in outer serobe. Maxillae
