and cover a much greater portion of the elytra; in that case they 
would approach in pattern C. ornata, described by me from Lake 
N’Gami. The present species, however, is nearly twice the size 
of C. ornata, and much less coarsely punctured. 
Genus Curysometa, Auct. 
Chrysomela (Atechna) Clarkii. 
Ovato-rotundata, valde convexa, rufo-picea, nitida; pedibus 
obscurioribus ; antennis nigris, capite thoraceque obscure 
rufis ; elytris obscure rufo-violaceis, subfortiter punctato- 
striatis, interspatiis planis, subremote tenuiter punctatis ; 
utrisque pustulis rotundatis quatuor 2-2 oblique positis flavis.

This lovely insect, the finest of the known species of Atechna, 
is at once to be distinguished from all its congeners by its much 
greater size; I have named it after my friend the Rev. H. Clark, 
who is just now engaged on a monographic paper of the genus 
Atechna. 
The four spots on each elytron form two obliquely transverse 
rows on the disc; the first placed before, the second below the 
middle. 
Genus Austratica, Chevr. 
Australica (Stethomela) Parryi. 
Subquadrato-oblonga, parallela, valde convexa, cuprea, nitida, 
zeneo-micans, subtus cupreo-zenea; antennis basi pedibusque 
obscure rufo-fulvis, illis apice nigris ; elytris pone medium 
declivibus, apice angulatis, profunde punctatis, punctis in striis 
remote dispositis.

Head smooth, impressed just above the epistome with a few 
deep foveze. Clypeus fulvous, epistome fulvo-azneous. Thorax 
more than twice as broad as long, sides straight and nearly pa- 
rallel, narrowed and rounded in front; disk smooth, very minutely 
punctured, impressed here and there on the sides and hinder 
half with large deep punctures, which have a metallic green re- 
flexion. ‘The punctures on the elytra, also metallic green, are 
similar in size to those of the thorax; they are arranged in nine 
rows, being placed at somewhat irregular and distant intervals in 
each row; in this respect they approach the punctation of Stetho-
