Sp. 3. Bifrons. — This insect belongs to Monsieur 

 Serville's genus Inca, and seems confined to the 

 New World ; there are several recorded species 

 known. 



Sp. 4. Polyphemus. — This insect for many years 

 was considered unique, and was the chief ornament of 

 the Banksian cabinet : it has been stolen from thence 

 by some individual unworthy of the name of natu- 

 ralist. I regret to state also that a box containing some 

 rare and singular insects (from Sierra Leone and New 

 Holland) has disappeared from my own collection ; 

 should a similar occurrence take place I shall be 

 forced to close my cabinet, which it has ever been 

 my wish to render easy of access to the Entomolo- 

 gist. As the insect here above alluded to belongs 

 to a section which has the thorax trapezoidal, I sug- 

 gest the adoption of the generic term Mecynorhina 

 from the Greek words fXTjKvuco and pti', from the cly- 

 peus being prolonged into a horn. The following 

 characters will designate the type of form. Mecy- 

 norhina Hope: " Corpus ovatum, thorax trapezio- 

 dalis, caput tricorne, medio mergaformi porrecto, 

 bifido, lateralibus minoribus subarcuatis, apice acutis.
