154 THE CAKABIDAE OF TASMANIA, 



In size and shape resembling A. simsoni SI., but distinct by colour black; 

 bead larger; elytra more strongly striate, the striae more coareely erenulate, 

 seventii interstice well defined and seriate-punctate. It may be allied to Dy<coliis 

 australis Erichs., but does not agree with tlie description of that species by colour; 

 lonn of prothorax (also basal angles and lateral basal impressions) ; elytra evi- 

 dently far more strongly striate, etc.; in all the characters just mentioned it 

 differs even more from the description "f O. iJilatatus Erichs. 



Amblytelu.s simsoxi, sp. no\-. 



Oval; inothorax cordate, rounded on sides; basal angles obtuse, two maigmal 

 setae on each side; elytra oval, wide, liglitly punctate-striate (sixth and seventii 

 striae faint or obsolete), third interstice with three punctures, fifth interstice with 

 one or two fine punctures on disc, seventh interstice impunctate. Brown (iiead 

 and prothorax piceous brown, elytra reddish brown) ; legs, antennae, palpi, and 

 abdomen fenniginous (tibiae darker than femora) ; prosternum and mesostcnum 

 reddish piceous. 



Head large (1.7 mm. across eyes), lightly angustate behind eyes; vertex con- 

 vex; front depressed; eyes prominent. Prothorax broader than long (1.7 X 2.1 

 mm.); apex (1.5 mm.) a very little narrower than base; base arcuate, very 

 lightly sinuate on each side ; lateral border wide, cut obliquely behind basal angles ; 

 lateral basal impressions well developed, short, wide; median line lightly im- 

 pressed. Elytra oval (5.4 X 3.5 mm.), convex; five inner striae well marked, 

 fine, erenulate; interetices depressed. Met-episterna (without epimera) about a.s 

 broad as long. Tarsi with fourtli joint of anterior wide, deeply excised; of inter- 

 mediate bilobed (outer lobe a little longer than inner); of posterior wide, imar- 

 ginate, outer side produced into a short lobe. Leng-tli, 8, breadth, 3.5 — 3.8 mm. 



Hob. — Tasmania (Simson, No. 3314). Three specimens. A fourth speci- 

 men is darker in colour, proportionately a little wider, and more decidedly striate, 

 but seems conspecific. Ben Lomond, 4000 feet (Simson). 



In tlie Simson collection this species was named Di/scohis dilatatus Erichson, 

 but it does not at all suit the description of that siiecies; attention may be drawn 

 to the following differences from Eriehson's description of D. dilatatus : — Colour 

 not "subaneomicans" ; antennae and prosternuiu not testaceous; basal angles of 

 prothorax not "deiiticiili iiistar subprominulis" ; elytra not "subtiUissime obsole- 

 tpifue striatic." Erichson makes no mention of jiunctures on the third and fiftli 

 interstices in the descri))tion of I), dilatatus, and in all his descriptions of otiier 

 Tasmanian Carabs these punctures are carefully recorded, when present. It may 

 be near D. australis Erichs., l)ut I cannot think it agrees with that si>ecies in 

 colour — "metallico-nilidus" ; it has not the basal angles of prothorax ^'promiiiulif: 

 aubrectis" ; and the elytra are t(io decidedly striate to be described as "siibl'litrr 

 nbsolete<iue purictiito-striatis." 



AilliLVTKLrs NIGER, Sp. nOV. 



A])terous, oval; jirothorax of about equal width at base and apex, rounded on 

 sides, basal angles not marked, anterior marginal seta present, basal seta wanting; 

 elj-tra oval, wide, feebly striate, striae obsolete towards sides, eighth entire. 

 Black; tibiae reddish piceous; tarsi and antennae reddisli. 



Head convex (1.5 across eyes), depressed between eyes, liglitly and obli(|uely nar- 

 rowed behind eyes; frontal impressions feeble; eyes jirotuberant. Prothorax broader 

 tiian long (1.5 X 2 mm.), widest before middle, subdepressed ; apex lightly eniaryin-
