106 Rev. F. W. Hope on some rare and 



To the same genus belong Lucanus Dalmanni and Luc. Cumingii 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 parum breviori- 

 bus. 



Long. lin. 26 \ \ lat. lin. 9. 



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



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



unispinosi. 



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 parum longioribus : dente forti fere trigono 

 ante basin posito : reliquis minoribus. 



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



Habitat in agro Assamensi. 



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

 apicibus valde acutis, dente valido supra et interne instructae. Thorax laevis, 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 valde exsertis denticulatis capiti tboracique sequalibus, tho- 



race postice utrinque dentato, elytris glabris marginatis. 

 Long. lin. 21£ ; lat. lin. 6|.
