454 THE INSECTS OF KING'S SOUND AND ITS VICINITY, 



more distinctly striate-punctate, with a large black triangular 

 patch, common to both elytra, behind the middle, the base of the 

 triangle uppermost ; also, one or two small black spots near the 

 sides at the apical third. 



Length, 2| lines. 



33, Sarathrocrepis notabilis, n.sp. 



Of the size and general appearance of S. liturata, but the head 

 more triangular in front, and the impression on each side of the 

 clypeus and forehead extending to between the eyes, the thorax 

 smoother, the elytra more ampliated. On each elytron at the 

 suture at the apical third is a squai'e black spot, which gives the 

 appearance of a short abbreviated fascia common to both. 



Length, 2 lines. 



The number of species of this genus in Australia is something 

 wonderful, many of them still undescribed, and many of those 

 described have Vjeen so imperfectly characterised as to make it 

 extremely dithcult to tell what is new or what is old. I believe, 

 however, that in this respect I have made no mistake in the 

 above four species. 



34. Plochionus humeralis, n.sp. 



Dark pitchy brown, nitid. Head linearly impressed on both 

 sides from the eyes forwards, with a horse-shoe-shaped impression 

 in the middle ; the labrum is shorter than the width, and rounded 

 in front ; the eyes are large and prominent. Thorax transverse, 

 broader than the head, nearly truncate in front and behind, the 

 antei'ior angles very round, the posterior rectangular and acute, 

 the lateral margins broad, bi'oadest at the posterior angles, and of 

 a reddish colour ; the disk sub-convex, and very finely transversely 

 stx'iolate and canaliculate in the middle. Elytra much broader 

 than the thorax and three times the length, strongly striate and 

 extremely minutely punctate, the base concave in the middle, the
