Hah. — Phillips River district, West Australia. 



I am indebted to that enthusiastic and indefHti<j;able collector, 

 Mr. C. French, of the Victorian Department of Agriculture, for 

 a pair of the above distinct species, which I have great pleasure 

 in dedicating to him in appreciation of his services to entomology. 

 While belonging to the same group as //. echidna White, and H. 

 Macleayi Bieme, it differs markedly from eacli; the elytral costse 

 of H. Frenchi replacing the spines of the former, while the costse 

 of the latter are much less prominent, and not broken up into 

 teeth beliind, with the many other differences shown above.
