and has two obvions impressions. Each elytron has six fur- 

 rows, united in pairs at the base ; the fifth ceases at about half 

 the length of the elytron ; the sixth is rudimental only. 



Inhabits Brazil. A single specimen is in the cabinet of the Rev. 

 F. W. Hope, and three others in that of Mr. Children.

 This species so closely corresponds with the foregoing that 

 I have considerable hesitation in considering them distinct. 

 The present insect is rather less in size, rather less glabrous, 

 and scarcely so broad in proportion to its length : there is 

 again a difference of habitat, the Cucujus rufus of Fabricius 

 inhabiting the United States, and the Isonotus castaneus of 

 Perty inhabiting Brazil ; and I may remark it is a circum- 

 stance of extremely rare occurrence that the same species is 

 common to both countries. That the present insect is the 

 Cucujus rufus of Fabricius appears pretty evident from that 

 author's description, which I subjoin below. There is a spe- 

 cimen in the cabinet of the British Museum, a second in that 

 of the Entomological Club (donor J. O. Westwood), and a 

 third in that of Mr. Westwood, which is the identical speci- 

 men described by him in the c Zoological JournaP as the type 

 of his genus Catogenus, and which he has kindly placed in my 

 hands for examination and description. It is useless to repeat 

 the description already given with C. castaneus ; the reader 

 must refer to that species, notice the slight variation above al- 

 luded to, and add the following description from Fabricius in 

 the e Entomologia Systematica/ remembering also the differ- 

 ent locality ; a subject formerly so much neglected, that I find 

 it a matter of difficulty to obtain the habitat of any rare spe- 

 cies if it happen to boast of any antiquity.
