172 THE INSECTS OF GAYNDAH, 



Thorax transversely impressed in the middle, with a transverse 

 series of five fascicles immediately behind the impression. Elytra 

 coarsely punctato-striate, with four rows of lengthened fascicles 

 on each, one on the third interstice consisting of five or six fasci- 

 cles, the second on the fifth interstice of four fascicles, the third 

 on the seventh of three, and the fourth on the ninth of two. 

 There are a few brown scales mixed with the black in some 

 places. 



This species is larger than M. sphaericus or Australis, and 

 more regularly striated on the elytra, while in M. scoparia the 

 striation of the elytra is much finer than in any of them. 



322. — MiCROCHiETES COSTATDS. n. Sp. 



Length 1 line. 

 Black and scaly. Thorax not produced in front over the 

 head as in the other species of the genus, but receiving the head 

 in the emargination of the anterior border. Elytra very finely 

 striate-punctate, with five narrow costae on each, and with the 

 intervals quite flat. 



This ought probably to constitute a new genus. 



323. LiMNICHUS FRONTALIS. n. Sp. 



Length I of a line. 

 Black, opaque, finely punctate. Head with a large triangular 

 impression on the forehead. Thorax very broad, scarcely emar- 

 ginate in front, and widening much towards the base, which is 

 broadly rounded. The elytra are very finely punctato-striate. 



GEORTSSID^. 



324. — Georyssus Kingii. n. sp. 



Length | a line. 



Black, opaque. Thorax rough, granulose, rounded and rather 



produced over the head in front, and a very little emai'ginate at 



the apex, with the median line bi'oadly marked, and the base 



broadly rounded. Elytra shortly ovate and convex, with four
