368 Mr. F. P. Pascoe on some new or little-known 



Amimes [Cerambycidae]. 

 Head very short and rounded in front, narrowed behind the eyes. An- 

 tenna? eleven-jointed, arising between the eyes from short divaricate 

 tubercles, two or three times as long as the body, setaceous, the basal 

 joint short, narrowly subpyriform, the third twice its length, the re- 

 mainder gradually longer. Eyes large, prominent, renifonn. Palpi 

 slender, pointed. Lip and epistome very short and transverse. Man- 

 dibles entire at the apex. Prothorax elongate, irregularly subcylindrical, 

 narrower than the head and elytra, unarmed. Elytra subparallel. Legs 

 slender, basal joint of the tarsi elongate. Anterior cotyloid cavity 

 widely angulated externally, open behind ; its coxa? conical, approxi- 

 mate. Pro- and mesostema simple. 



The specimen from which the above generic details have been 

 drawn up was originally described by me in the ' Trans. Ent. So- 

 ciety,' 2nd ser. iv. p. 238, as Psihmerus ? maeilentus. The generic 

 name was a MS. one used for a congener at the British Museum, 

 but, as I afterwards found from an inspection of the true Psiloments 

 at Paris (Jardin des Plantes), had nothing whatever to do with my 

 species. As I cannot refer it to any published genus, a new name 

 has therefore become necessary. With regard to its affinities, I have 

 with some hesitation placed it near MetMa, Newm., hitherto forming 

 with Dysphaga, Hald., a small group, originally proposed by Leconte, 

 and principally characterized by its anterior cotyloid cavities open 

 behind. M. James Thomson in his ' Essai,' p. 128, combines Deetes, 

 Leconte, with them ; but this and Dysphaga I have not seen.

 posticis albis. 



Hab. Australia (Adelaide). 



Very narrow and elongate, ferruginous ; head punctured in front, 

 deeply impressed between the antenna?, the vertex dark brown ; pro- 

 thorax punctate-granulate, very irregular, with a protuberance at the 

 side near the base, and another on the disk above it ; scutellum small, 

 bluish-black ; elytra terminating at the end of the third abdominal 

 segment, reddish testaceous, with a strongly raised longitudinal line 

 on each ; abdomen above dark brown ; legs slender, posterior tarsi 

 yellowish white ; body beneath brown, abdomen at the base ferruginous ; 

 antenna? not reaching to the end of the elytra, dull brown, the basal 

 joint ferruginous, the three apical yellowish white. Length 8 J lines.
