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



Amimes [Cerambycidse]. 



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

 tennae 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 subpyrifomi, the third twice its length, the re- 

 mainder gradually longer. Eyes large, prominent, reniform. 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 coxae conical, approxi- 

 mate. Pro- and mesosterna simple. 



The specimen from which the above generic details have been 

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

 ciety,' 2nd ser. iv. p. 238, as Psilomerus ? macilentus. 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 Psilomerus 

 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 Methia, Newm., hitherto forming 

 with Dyspliaga, 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 Dectcs, 

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