366 Df;sci!ii'Tioxs of nkw spj^ctk.s of austii^vlian coleoptera, 



but ciu others the black does not extend to the sides, the spot on each elytron is 

 median, of irregular shape, and extends across about five interstices. 



Stenoi'aksus aIjTkrxatus, n. sp. 



Black; an obscure spot on eacii side oi prothorax, four vittae ou elytra, and 

 elytral epipleurae more or less red. Moderately clothed with semi-erect, rusty 

 hair. 



Head with snuiU punctures, a shallow depression between eyes. Antennae 

 comparatively long, club stout, apical joint almost as long; as two preceding;- cnni- 

 bined. Prothorax with sides strongly rounded in front, apex almost semi- 

 ctreularly emarginate. sulilateral striae deep, becoming foveate at base; with 

 .small but rather sharply defineil punctures, becoming rather coarse and dense 

 on sides. Elytra with rather strongly rounded sides, widest at about basal 

 fourth ; with rows of ratlier large punctures in feeble striae, the interstices with 

 small but distinct punctures. Length, 3.25 nun. 



Hab. — New South Wales: Kiania (unique). 



Structurally close to ,s'. arithvieticiis, and to several other si>ccies. but red 

 elytral markings longitudinal; the vittae commence at the base and terminate 

 near the apex, they are on the third and seventh interstices, but tlie one ou the 

 seventli is interrupted on each eh-tron near the ba.se; the spot on each side of 

 the prothorax is distinct inunediately behind the eye, but may be traced almost 

 to the base; the tarsi and palpi are (pl)scurely diluted with red. 



Periptyctus bryophilus. n. sp. 



Flavous; middle and hind angles of prothorax, scutellum, greater portion 

 of elytra, middle and base of prosternum, part of abdomen, coxae and club, more 

 or less deeply infuscated. Upper surface glabrous, under surface almost so. 



Jlead with fairly dense and sharjjly detined punctures. Antennae rather 

 long, fli-st joint stout, second as long a-s flret but much thinner, third-eighth small, 

 ninth-eleventh forming a club. Prothora.r at base scarcely twice as wide as the 

 median length, sides thickened and strongly rounded, apex about half the width 

 of base and gently incurved to middle, base bisinuate, hind angles acute, convex 

 along middle, concave towards each side; punctures sparse and inconspicuous. 

 Scutellum widely transvei'se. Elytra sliglitly wider than prothorax. a suli- 

 foveate impression on each side of base; with rather large punctures; in places 

 somewhat seriate in arrangement, but not in striae. Under surface with numer- 

 ous ratlier small but sluirply delined punctures, less conspicuous on chin-piece 

 than elsewhere. Lengtli, 2.25-2.5 mm. 



Hub. — Tasmania: Mount Wellington (A.M. Lea). 



A l)eautil'ul little species ol' which two specimens were olttained from moss. 

 It is larger and wider than P. riissulua, very differently coloured, sides of pro- 

 thorax diilerent. elytral punctures larg<>r. etc.; from tiie description of P. eximiv-s 

 it differs consideral)ly in colour and sculi)ture. On the larger specimen the dark 

 parts of the prothorax are almost black, its elytra liavc the l)asal fifth, except 

 for a spot half-way between the scutellum iind each shoulder, and sides pale, 

 enclosing a large sliield-sliapi'd space, and its abdomen has a large sulitriangnlar 

 dark space; on the smaller specimen tlie markings arc less dark, an<l much less 

 of the abdomen is infuscated. The joints of the club are flattened, and from 

 one point of view a|)pear scarcely wider than the iireceding joints, but from 

 another point they ajij^ear almost thrice as wide.
