396 Mr. E. Newman on the Genus Passandra, 



Sp. 8. Hect. semifuscum. Caput et prothorax f us ca, catera obscure 

 ferruginea; linece prothoracis dualaterales, antice obsolete, discus 

 complanatuf, punctatus ; singuli elytri stria quatuor pariter dis- 

 positce. (Corp. long. *4 unc. lat. *08 unc.) 



Head and prothorax dark brown, elytra, abdomen and legs 

 ferruginous. The head is rugose ; there is a very obvious 

 impression on or rather behind the clypeus ; the transverse 

 and longitudinal furrows of the head are deep and very di- 

 stinct; the antennae are somewhat more slender, and the joints 

 more elongate than in the others of this genus; the terminal 

 joint is also much larger. The prothorax has a posterior and 

 lateral marginal ridge, the posterior portion being incrassated, 

 reflexed, and notched in the middle ; on each side a line arises 

 from the posterior angle, and proceeding upwards towards the 

 anterior margin ceases at about half the length of the protho- 

 rax. Each elytron has four striae in pairs ; the first originates 

 by the side of the scutellum and extends to the apical angle ; 

 the second, approximate to the first, is considerably abbreviated 

 at each end ; the third, distant from the second, is also abbre- 

 viated at each end, but extends rather below the second ; the 

 fourth approximates to the third, originates nearer the shoulder, 

 and extends rather below it. 



Habitat unknown. There is one specimen in the cabinet of the 

 British Museum without record of its locality. 



Sp. 9. Hect. rufipenne. 



Cucujus rufipennis, Fab., ' Syst. Eleu.' ii. 93. 



" Black, with the elytra alone ferruginous." — Fab, loc. cit. 



" Inhabits the island of Sumatra. In the museum of M. Sehestedt." 



The brief description of this species agrees tolerably well with 

 H. semifuscum, but as it enters into no particulars whatever as to the 

 sculpture, it would be inexcusable to conclude from so trivial a simi- 

 larity as that of colour that the species were identical. 



Genus Catogenus, Westwood. Isonotus, Perty. Aniso- 



cerus, Hope. 

 Antennae moniliform and of equal thickness throughout. 

 Head with two deep frontal longitudinal furrows which do not 

 reach the transverse posterior furrow. The tarsi are very di- 

 stinctly 5 -jointed.
