from Australia and Tasmania. 229 



1 st, tlie 3rd joint elongate, the 4th to 6th diminishing in 

 length, 7th a little longer than broad, 8th as broad as long, 

 9th and 10th forming distinct but not a large club. Tho- 

 rax transverse, narrowed in front, lobed in the middle of 

 the base. Elytra convex, at the base the same width as the 

 thorax, arcuate at the sides ; the epipleural fold gradu- 

 allj narro^ying to the apex, a little concave at the extreme 

 base, slightly convex posteriorly, not separated from the 

 elytra by a sharp edge. Tarsi slender, moderately long, 

 pubescent below, the basal joint of the posterior pair 

 long, as long as the 2nd, 3rd and half the 4th taken 

 together. Prosternum horizontal, parallel. Mesosteruum 

 sloping anteriorly. 



This insect is regularly oval, convex and finely pubes- 

 cent. It appears to be allied to Platydema, but the 

 antennae are more like those of Heterophijllus. I think 

 it should be placed before this latter.

This insect has somewhat the form of Rhizobius litnra 

 among the CoccinellidcB, but the elytra are still more 

 exactly adapted to the base of the thoi-ax.
