This species closely resembles the preceding; the lateral' 

 ridges are more distinct on the thorax and elytra ; the depression 

 on the thorax is less decided, the punctures on the thorax much 

 larger, and the whole insect is larger. The form of both this 

 and the preceding species greatly resembles that of Ehnis ceneus. 



Elmis punctulatus. 



Niger ; antennis gracilibus ; thorace minutissime punctate 

 linea media longitudinal! impresso ; elytrorum disco 

 irregulariter minute punctate. 



Long. 006 poll. 



Paramatta River ; on a submerged branch. December. 



The lateral lines on the thorax and elytra are in this species 

 almost obsolete. It very closely resembles the preceding species, 

 but is rather larger, and the punctures on the disk of the elytra 

 are not so regu.lar. The inner edge of the fore tibias is strongly 

 spine d. 



LiMNius. Illig. 

 Sect. 1 . No lateral ridges on elytra. 



LiMNIUS QUATUOR-MACULATUS. 



Politus irregulariter punctatus ; antennis gracihbus ; thorace 

 ad medium transverse depresso, sulcis lateralibus dimi- 

 diatis ; scutello subtriangulari punctate ; elytris 4 maculis 

 testaceis magnis. 

 Long. 0-06. 



Under stones in Paramatta River. In company with Elmis 

 politus and E. novem. notatus. 

 The maculfe on the elytra vary in size in different indi- 

 viduals, especially those near the shoulders ; so much so, indeed, 

 that in some individuals, they coalesce and form a wide testaceous 

 transverse band. On the maculte the punctures disappenr, but 

 not the setse. The subtriangular scutellum hardly agrees with 

 the form of that organ in other species of this genus, and 

 closely connects this interesting form with Ehnis, if, indeed, it 

 ought not to be "placed in that genus.
