Neiv Species of Heteromera, 321 



scutellum broadly rounded behind^ punctured ; elytra 

 strongly bisinuate at the base ; with a somewhat deep 

 depression behind the basal callosities ; punctate-striate, 

 the punctures rather large ; very strongly and trans- 

 versely wi^inkled, and irregularly punctured^ on the inter- 

 vals ; underside black without any brassy tinge ; densely 

 pubescent ; densely and strongly punctured ; abdomen 

 closely and transversely rugose-punctate ; organs of the 

 mouthy and legs, pitchy black ; the tarsi a little paler ; 

 antennas, save the second joint which is red, black. 



Hah. — South Australia. 



I have not seen the male of this species, which is 

 very distinct from all the others by its colour, and the 

 strongly wrinkled surface of its elytra. 



Fam. LAGRIID^. 

 Xenostethus, n. g. (PI. XY. fig. 5). 



Male: — suh-mentum pedunculate* {i.e. rising consi- 

 derably above the level of the bottom of the maxillary 

 sinus), broadly arched in front; w^eHiztm strongly trans- 

 verse, convex, arcuately emarginate in front, fore 

 angles somewhat pointed, sides rounded before the 

 middle, thence contracted to the base ; sparsely clothed 

 with a few long suberect hairs ; labium very prominent, 

 transverse, its paraglosste (?) enormously developed 

 (overlapping the ligula, which they nearly conceal), 

 more or less closely united at their inner margins, and 

 forming, thus conjoined, a transverse sub-triangular 

 body, its sides incurved with the margins broadly re- 

 flexed, its apex more or less pointed and fui-nished with 

 a tuft of hairs ; the ligula being visible only at the base 

 and through a narrow triangular cleft in the junction of 

 the paragloss^ (?) behind ; labial palpi short, somewhat 

 robust; last joint short, strongly curved outwardly, the 

 apex broadly and somewhat obliquely truncate ; inner 

 lobe of viaxilla rather small, foliaceous, clothed with 

 longish hairs ; the outer lobe masked by a large plate, 

 which is oblique, of an oblong form, broad and rounded 



* M. Lacordaire in his definition of the family, says :• — " Menton 

 non porte par un pedoncule dn sous-menton ; " this is certainly an error, 

 for, in the whole of the genera, the sub-mentnm is more or less pedun- 

 culate ; in the genus Statira it is even more strongly so than in Xeno- 

 stethus.
