398 Harris's Description of 



hceus torquata and micans of Drury, together with both sexes 

 of the gigantic beetle called Goliathus Cocicus by Gory and 

 Percheron,* but differing from the true Cacicus of Voet, in 

 having a triangular black patch on the shoulder of each 

 elytron. The cabinet of the Essex County Natural History 

 Society, at Salenij contains these same species, together with 

 a male and female of Goliathus or Hegemon Drurii, and other 

 valuable insects, mostly brought, by Mr. George A. Perkins 

 from Western Africa. 



The writer of this article has enjoyed the rare opportunity 

 of seeing all the Goliath beetles in these cabinets, as well as 

 those in the private collections of Dr. Savage and Mr. Perkins. 

 On this account, and not from any ambition to connect his 

 own name with the description of a new foreign species, he 

 has been induced to yield to the request of Dr. Savage in 

 drawing up the characters of the Polyphemus and of the new 

 species allied to it, and has ventured to prefix to them some 

 observations on the remarkable group to which these insects 

 belong. 



Lamarck instituted the genus Goliath, or Goliathus, as it is 

 now generally denominated, in the year 1801, for the recep- 

 tion of ScarahcBUs Goliatus, Cacicus, Polyphemus, and some 

 other species. 



Most of the insects included in this genus are large, and 

 some of them are of gigantic proportions, and are much prized 

 for their beauty and extreme rarity. The clypeus of the males 

 is generally forked or armed with horns. The mentum is 

 wide, deeply notched, and divided into lobes, and the origin 

 of the labial palpi is concealed within a deep sinuated furrow 

 in the outer edge of each lateral lobe. In the African species, 

 the maxillae are horny, and are furnished with teeth and a 

 terminal brush or pencil of hairs ; the mandibles end with a 

 thin and horny lobe ; the epimera or frusta are more or less 

 conspicuous between the outer angles of the thorax and the 

 shoulders of the elytra, and the latter are dilated and promi- 



* It is surprising that these authors and subsequent writers have not noticed the 

 ditference between Voet's species and this insect.
