NOTl;S ON SOME AUSTRALIAN TENEBRIOXIDAE, 



tened; epistoma arcuate (concave) iu front, without marked sulcus separating 

 forehead; meutum cariuate in middle, its sides straight and narrowing to apex — this 

 bilateral, fuiiuing a triangular notch; all palpi with apical joints securiform, 

 i'ront coxae round, posterior transverse, all coxae furn- 

 ished with troehantins. Prostenium convex, produced 

 oetween fore-coxae into a blunted process, received into 

 a triangular inesosternal notch; mid-intercoxal process 

 widely, post-intercoxal process squarely rounded, abdomen 

 with wide longitudinal depression; fore-tibiae strongly 

 ueni and enlargeil at apex, post-tibiae curved and strongly 

 tomentose within, all tibiae shortly bispinose at apex; 

 elytra sulcate-sub-puuctate. A genus quite at variance 

 with any other yet described. ^lore ijvate than Hi/ixiuJax, 

 less so than Asphalus^ more depressed than either, its 

 most striking features are the combination of the usual 

 Tenebrioninae characters of the bead, body, and strongly 

 cur\ed tibiae, together with more elongate antennae and 

 a sculpture sui generis. 



MeNEARCHUS lilPRESSO-SULCATUS^ n.sp. (Text-fig. 3.) 



Opaque black above, nitid beneath, glabrous; antennae, 

 oral organs and tarsi piceous. Head large and flat, labrum 

 emarginate. epistoma arcuate, its sides ailvanced ; antennal 

 orbits wide and depressed; eyes narrow and transverse; 

 Text-fiij. S.| u]iper surface — like that of prouotum — uniformly very 



Meneuir/iiis im- densely and finely punctate. Frothora.r: 5X7 mm. 



presso-siilcaliis. (length measured in middle), arcuate emarginate at apex, 



bisinuate at base, anterior angles sub-acute, tips blunted; sides evenly rounded, 

 widest at middle, posterior angles rather widely acute and produced so as to over- 

 lap slightly the elytra; lateral border narrowly raised — not sulfite within — still 

 narrower at base and ol)solete at apex; disc with a faint indication of medial 

 channel. Scutellum convex, strongly transverse, punctate. Elytra slightly wider 

 than prothorax at base and two and a-half times as long, widest behind middle, 

 cpipleural fold forming a marked but wide humeral angle; with 9 sulci, in- 

 cluding extreme lateral one (besides a very short scutcllary sulcus) ; the intervals 

 evenly and roundly convex and impressed on sides by shallow sub-jnmctate im- 

 pressions, these more pronounced laterally, the two outside sulci definitely punctate; 

 intervals everywhere covered with dense system of fine punctures as on head and 

 pronotum. Undersurface and legs closely punctate, abdomen more coarsely and 

 less closely than upper surface, hind femora dentate — a line of tomentum extending: 

 from base to this tooth ; fore-tibiae having apical third abrui)tly bent inwards and 

 thence mudi enlarged, mid-tibiae triangularly enlarged at apex, posterior tibiae 

 strongly curved, widely dentate near base, with a line of coarse tomentum on inner 

 edge; three basal joints of front tarsi enlarged, basal joint of hind tarsi about as 

 long as the 2nd and 3rd combined. Dimetnfions: 19 — 20 x 7J — 8 mm. 

 II ah. — New South "Wales (Mr. Deuqnet). 



Two c? specimens taken by Mr. Deu(iuet, one of which has been generously 

 idaced at my dis])osal. Tlie tibial diaracters alone would distinguish this unusual 

 insect from any other Australian member of the Tenehrionidae.
