3. — EURYSCAPHDS MINOR. 



Niger svibnitidus, thorace marginato augulis posticis rotundatis 



subreflexis, elytris laevibus. 

 Long. 11 lin., lat. 5 lin. 

 Hab. Victoria River, Mitchell's Expedition. 

 The facial grooves are without wrinkles in this species. The 

 thorax is very like that of the species last described, excepting 

 that the posterior angles are less reflexed. The elytra are smooth 

 and nearly circular, with the base scooped out. The legs are as 

 in the last described species. 



4. — EuRYSCAPHDS BIPUNCTATUS. 



Niger nitidus, fronte subrugosa, thorace subsemicirculari, 



elytris convexis substriatis puncto in medio impressis. 

 Long. 15 lin., lat. 7| lin. 

 Hab. South Australia. 



The head is rugose in front, and the facial grooves are not 

 connected together behind. The thorax is almost semicircular 

 without being lobate at the base. The elytra taken together are 

 convex and nearly circular, with the base scooped out, while they 

 are indistinctly marked with strioe, and have a large puncture 

 near the centre of each elytron. The legs are wanting in this 

 specimen. 



I received this insect very lately from Mr. Waterhousc of 

 South Australia ; it adds another to the very many valuable 

 specimens I have received from that gentleman. 



To the four species just described, ScarapMtes ohesus and 

 Scarapldtes Waterhousei must be added, for both these insects 

 clearly belong to this genus. The former is stated by me in a 

 former paper to be from Swan River. I am not at all sure, 

 however, that I am correct in that. The other E. Water- 

 housei is from Central Mount Stewart. 



Of the six species now forming the genus Euryscaphus, E. 

 cUlatatus, and E. minor are very nearly alike. E. hipunctatus and 

 E. ohesus also closely resemble, while E. Waterhousei and E. 

 angulaius are veiy distinct.
