NEW GENERA OF COLEOPTERA. 511 



a delicate brown pubescence : thorax coarseh' rugose, with a 

 prominent acute spine on each side, about the middle : elytra ob- 

 soletely rugose, interspersed with a few deep punctures, and hav- 

 ing two abbreviated rows of obtuse and compressed tubercles at 

 equal distances from the suture and from each other, and parallel ; 

 the first tubercle of the inner row forming an acute spine ; this 

 series terminating just beyond the middle of the elytra, and the 

 external one continuing a little farther : the tibiae covered with a 

 brown silky down. 



From Van Dieman's land. This singular insect closely re- 

 sembles in habit an Amycterus, with the antennas of a Longi- 

 corn. I do not hesitate placing it in Serville's genus Morimus, 

 although the antennse are approximate, which would perhaps, 

 in his opinion, require its being formed into a distinct genus. 



Tribe. — MoRDELLONiE, Latreille. 

 Genus. — Pelecotoma, Fisch. 



Sp. Pelecot. Fischerii. Shuck. Castaneum, aureo-tomentosum, 

 alhido lineatum et maculatum; elytris conniventibus. (Length 

 9 lines.) 



Entirely of a pale chestnut ; covered on the head, thorax, extreme 

 base of the elytra, and beneath, with a dirty grey down which be- 

 comes of a bright golden tinge at one-third of the length of the 

 elytra, at the base of which there are three indistinct longitudinal 

 parallel white lines, terminating about the middle ; just beyond 

 which, there is a broad whitish band, interrupted at the suture ; 

 and beyond this an elongate cordiform whitish mark, common to 

 both the elytra, which are narrowly marginated both at the suture 

 (where they are united) and externally: the edges of the abdo- 

 minal segments quite white. — A female, from the Brazils. 



Ohs. — ^I have much pleasure in dedicating this fine insect to 

 the distinguished entomologist who is the author of the genus. 

 I have no doubt of its being different from the Pelecot. Leachii. 

 (Latr. Diet. d'Hist. Nat. torn. xxv. p. 135,) than which also it is 

 larger. According to the descriptions, it would most resemble 

 the Pelecot. LatreilUi of St. Farg. et Serv. in the Ency. Met. 

 torn. X. p. 3!2, No. 2 ; but the distinctions of size, and the dis- 

 position of the white markings, induce me to think it different 

 from that also.
