Lucanoid Coleoptera. 99 



Hob. — Ins. Philip. 



Long. 4^ lin. In Mus. Brit. 



Considerably smaller than Gardamis sidcatus, West., 

 but closely allied to it ; the head more strongly punc- 

 tured, less emarginate in front, the angles in front of the 

 eyes rounded, instead of being rectangular as in C. sul- 

 catus, the prothorax less closely punctate, the interstices 

 of the elytra, moreover, are smooth, and the external 

 denticulation of the tibiae not so strong. 



Ceratognathus Westivoodii, Thomson. 



The $ of this species, hitherto unknown to our collec- 

 tions, has recently been received at the Hopeian Museum, 

 Oxford ; it was sent by Dr. Howitt, from Melbourne, as 

 distinct, and under the MS. name of G. setiger. The $ 

 is readily distinguished from the c? by its very short and 

 more strongly punctured mandibles. 



Ceratognathus helotoides, Thomson. 



Specimens, both $ and $ , of this hitherto rare species 

 have recently been received both by Mr. Bates and my- 

 self, from the province of Canterbury, New Zealand, 

 collected by Mr. Fereday. C. helotoides has, I believe 

 erroneously, been stated as belonging to the Australian 

 fauna. 



Ceratognathus ahdominalis, n. sp. ( ? ) . 



C. parvulus, cylindricus, punctatissimus, brunneo- 

 obscurus ; elytris costis nonnullis obsoletioribus longitu- 

 dinalibus, interstitiis irregulariter maculis cinereis notatis ; 

 abdomine subtus rufo-piceo; tibiis posterioribus iner- 

 mibus. 



Hah. — Moreton Bay. 



Long. Corp. 5 lin. 



A single specimen only has fallen under my notice; it 

 assimilates in form and general character of sculpture to 

 C. niger, ? , but is considerably smaller, and of an obscure 

 brownish colour ; the elytra are furnished with several 

 small irregularly formed squamulose patches of grayish 

 colour, of which traces are visible on the prothorax; the 

 latter has a narrow polished longitudinal line extending
