To the same genus belong Lucanus Dalmanni and Luc. Cum'mgii of my 

 cabinet. I am aware also of other species which are wrongly regarded as 

 varieties of the Fabrician Luc. Alces. 



Dorcas, MacLeay. 



Sp. 4. Dorcas Westermanni. 



Niger, mandibulis porrectis multidentatis capite thoraceque parCim breviori- 

 bus. 



Long. lin. 26i ; lat. lin. 9. 



Thorax lateribus irregulariter angulatis. Elytra nigro-castanea, Hnei longitudinali (in sin- 



gulo) fere ad marginem impressa. Pedes antici tibiis denticulatis ; quatuor posteriores 



\uuspinosi. 



The above insect, received from Silhet, is named in honour of Westermann, 

 the prince of Danish entomologists. 



Sp. 5. Dorcas De Haani. 



Niger, mandibulis porrectis capite pariim longioribus : dente forti fer^ trigono 

 ante basin posito : reliquis minoribus. 



Long. lin. 22 ; lat. lin. 7^^- 



Habitat in agro Assamensi. 



Caput clypeo lato ciliato, prominentia frontis antice latiori. MandibulcB capite longiores, 

 apicibus valde acutis, dente valido supra et interne instructae. Thorax Iffivis, margi- 

 natus. Elytra nigra, nitida, lateribus rugoso-punctulatis. Pedes tarsis subtus auri- 

 comatis. 



I have described the above species from my own collection : it was pre- 

 sented to me by Lady Jones, and was taken in the Assamese territories. It 

 is here introduced, as it appears to recede from the typical oriental species of 

 Dorcas, and is named in honour of Professor De Haan of Leyden, an able ori- 

 ental entomologist. 



Sp, 6. LucANus Brahminus. 



Niger, mandibulis vald^ exsertis denticulatis capiti thoracique sequalibus, tho- 



race postice utrinque dentato, elytris glabris marginatis.
