The above insect I have named in honour of the Marquis de 

 Breme, the author of the Monograph on the family of Cossyphus ; 

 at first appearance it I'esembles in form Emcephalus of Kirby ; it 

 is however allied to Cilibe orbicularis.

The above species was sent to me by Mr. William Sharpe Mac- 

 Leay, under the name of echinata, which I have retained, as it 

 differs considerably in form from all other species,* and may form 



* [This species is most nearly allied to HelcEus ovaius, Gu6rin, Voy. de la 

 Coquille, t. 5, f. 7, but differs from that species in its longer and more regular 

 form, the thorax having a semicircular outline, and not being " ud peu retreci en 

 avant," and the tubercles of the elytra are replaced in H. ovatus by broad 

 spines. — J, O, W.'\
