CARABI DJE. 
By THOMAS G. SLOANE. 
Tachys spenceri, n. sp. 
Elongate-oval, convex ; prothorax transverse (not short) ; elytra bistriate on 
each side of suture, recurved stria of apex well marked, disc laevigate, quadri- 
punctate. 
Shining, polished; head and prothorax reddish-bi’own or piceous; elytra 
yellowish-brown near base, clouding to black across middle and near apex, a large 
spot behind middle on each elytron of paler colour than the base; antennae and 
legs (excepting coxaj and trochanters) pale yellow, coxre and under surface as far 
back as first \entral segment piceous-red, apex of abdomen reddish-testaceous. 
Head convex, smooth ; two short impressions diverging backwards between eyes, 
these impressions not extending to clypeus; eyes prominent. Prothorax wider 
than head, transverse, widest at anterior marginal puncture, lightly narrowed to 
base, truncate on base and apex, convex, hevigate, not declivous to middle of base, 
not transversely impressed near base ; sides rounded, not sinuate before posterior 
angles, these forming a short acute triangular projection just before the base; 
lateral border reflexed (widely and decidedly so at anterior marginal puncture) ; 
median line wanting ; a wide im^Dression on each side of base near posterior angles. 
Elytra much wider than prothorax, oval, subtruncate at base, rather narrowly 
rounded at apex, convex—a little depressed on disc—declivous to base ; stria3 
simple, first entire, second very lightly impressed, extending backwards from level 
with anterior discoidal puncture to posterior margin of light-coloured discoidal 
spot; a deep lateral stria besides the lateral channel on each elytron, interstice 
between these stride convex; lateral margin slightly interrupted just behind 
shoulders, causing the margin of the humeral angles to project a little. Anterior 
tibite cut shortly and obliquely to apex on external edge, a short projecting spur 
above the obliquity. Penultimate joint of maxillary palpi large, pyriform, 
hirsute; apical joint very small. Length, 2*7 mm.; breadth, P2 mm. 
Habitat. —Ellery Creek, Missionary Plains, Palm Creek, Rudall’s Creek, 
Paisley Bluff, McDonnell Ranges. Twenty-two specimens. 
I know of no described species that closely resembles this.
