368 DESCRIPTIONS OK -NKW SPKCIES OF AUSTRALIAN tX)LKOrTERA, 



Head with ratbtT dense small ]uiiictiires. Anteuuae moderately long-, first 

 joint stouter and slightly lunger than second, second stouter and longer than 

 third, fourth-eighth gradually decreasing in length, ninth somewhat longer and 

 distinctly wider than eighth, tenth still longer and wider, eleventh slightly wider 

 and about half as long again as tenth. I'ruthorau- at base scarcely twice as wide 

 as the median length, sides rather strongly rounded, and somewhat narrower in 

 front than behind; with a deep, continuous stria near each side, and another one 

 at base; punctuies small but sharply detined. Elytra at base slightly wider than 

 base of prothorax, widest at about basal third; with rows of rather large punc- 

 tures, becoming somewhat larger and more irregular about baj<e, and smaller 

 posteriorly; epipleurae fairly wide at base, very narrow beyond middle, and 

 disappearing before apex. Under surface with dense punctures, larger on meta- 

 sternum and basal segment of abdomen than elsewhere, the latter about as long 

 as three following segments combined, a small sixth segment traceable. Ij^gs 

 not very long; front coxae separated by a narrow keel. Length, 1.25-1.5 mm. 



Hab. — Tasmania: Hobart (A. M. Lea). 



At fli'st glance this species apjjears to be a Mycetaea, but the third joint of its 

 tarsi is minute and anchylosed to the fourth, instead of almost as conspicuous as 

 the second. It was referred with doubt io Idiuphyes, as the antennae are eleven- 

 jointed; it is decidedly narrower than 1. hreris, the elytral epipleurae are nar- 

 I'ower, and the clothing and punctures are different. 



LuKHMlVKS HUMERALIS, n. sp. 



Castaneous; shoulders, elytral epipleurae, legs and iialfii paler, dub (its 

 tip excepted) infuscated. Moderately clothed with semi-erect, pale pubescence, 

 spai'ser and depressed on legs and under surface. 



Head with two shallow interocular depressions; punctures indistinct. An- 

 tennae rather short, eleven-jointed, three apical joints forming a conspicuous 

 club. Prvthurax at base almost four times as wide as the median length, .sides 

 thickened, obli(|ue, Imt rounded in front ; a narrow deep stria near each side, 

 closed posteriorly but open behind the eye, bounded internally by an acute ridge; 

 ajiex iiu-urved at sides but .straight in middle, very finely margined, a naiTow 

 impression across base; with fairly numerous punctures towards sides, but sparse 

 in middle, Scutellum small and widely transverse. Elytra short, slightly wider 

 at base than prothorax, strongly rounded beyond middle, a rather deej) iini)ression 

 at base near each shoulder, sides distinctly margined; with fairly large, sharply 

 defined and numenuis, but not crowded piuictures; a feeble stria on each side of 

 suture. I'rostertiuvi with a distinct median keel, which is bistriated between 

 coxae. Length, 1.5 mm. 



Hab.— New South Wales: Sydney (A. M. Lea). 



A short, strongly convex species, the pale shoulders rendered more con- 

 spicuous by the depression at the inner side of each. In general appearance 

 nearer /. hrevis than /. diibiu.i, but the eleven-jointed antennae associate it with 

 the latter. On parts of the under surface the punctures are dense and sharply 

 defined, but they are much smaller in places; the abdomen appears to have a 

 minute sixth segment, but it may be an extrusible one; the prothorax is almost 

 glabrous in the middle.
