tinctly raised, with several tubercles overhanging the posterior 

 declivity, and with four projections at base. Length, 16-19 

 mm. 



9 ■ Differs in being more convex, elytra wider, a.pex 

 with two small mucros, tubercles overhanging the posterior 

 declivity smaller, and under-surface with a line pubescence 

 instead of a hairy ridge.

The elytra could scarcely be regarded as granulate, 

 although in places (especially on the suture and posteriorly) 

 a few almost obsolete ones are present ; this alone would 

 distinguish the species from granulatus. But the foveate 

 impressions are also different ; in this species, although very 

 irregular in shape, they are almost regular in continuity, but 

 in granulatus they are much fewer in number, more irregu- 

 larly disposed, shallower, and usually transversely conjoined. 

 The second interstice has a large tubercle overhanging the 

 posterior declivity, the third has a smaller one, and the fifth 

 a still smaller one : immediately below the tubercles there is a 

 somewhat concave space on each side. 



Mythites basalis, Boi. 



The original description of this species is very unsatis- 

 factory, but as it contains the expression "elytris . . . basi 

 quasi furcaits," I think it may be correctly applied to a 

 species I have long had named as Euomus basalis, Boi. This 

 species occurs at King George Sound, Swan River, and Gun 

 Island in Western Australia, and Port Lincoln in South 

 Australia. It has the sutural interstice of each elytron 

 obliquely joined on to the third at the base, so that it pro- 

 jects triangularly forward much as each shoulder does. In 

 other species of the genus the first and third interstices are 

 parallel at the base. 



The species was originally described as an Amycterus. 

 In Masters' Catalogue it appears under Euomus: but Pascoe 

 referred to it (without explicitly consigning it to the genus, 

 however) as a Mythites. I have also seen it as an Acanthomus 

 (a generic synonym of Mythites). 



Dialeptopus echinatus, Lea. 



On fresh specimens of this species the elytra are con- 

 spicuously marked with three white stripes, meeting at the 

 base and again at the summit of the posterior declivity. The 

 white appears almost like enamel, and is present on the 

 tubercles as well as on the general surface.
