This species would be ahuost equally well placed in the 

 genus Charisj sect. II. The hind thighs are longer and rather 

 more abruptly clavate than in any species of Charisj but they 

 are less so than in Phygopoda albitarsis. 



AcOEETHEA, nov. gen. 



Corpus, praeeipue abdomen valde elongatum. Caput parvum, rostro 

 liaululum producto, OcuU (S raagni antice fere contigui, 2 

 modice distantes. Antennce modice breves, articulis a sexto dila- 

 tatis, serratis. Thorax parvus, aiitice augustatus. Elytra cunei- 

 formia, obtusa, abdominis segmenti primi medium attingentia, 

 disco nitida. Pedes postici elongati ; femora gradatim clavata ; 

 t'lhhe liaud scopiferiB ; tarsi breves, Metasternum baud distentum; 

 abdomen J Hneare, gracile, 5 sessile. 



This genus is closely allied both to Charis and Phygopoda, 

 but cannot be united to either without rendering their defini- 

 tion impossible. The sim])le hind tibiaa and obtuse cuneiform 

 elytra distinguish it from Phygopoda ; and the elongated hind 

 legs and abdomen sejjarate it from Charis. The abdomen is 

 of disproportionate extension, exceeding by one half the length 

 of the rest of the body. 



Acoreihra chrysaspis, n. sp. 



A. gracilis, fusco-castanea, capite tboraceque obscurioribus, reticu- 

 lato-pvmctatis ; elytris cuneiformibus, disco pallide fuscis politis, 

 macula utrinque scutellari scutelloque aurco-tomentosis ; pectore 

 aureo-tomeiitoso ; segmento primo ventrali testaceo, caeteris ( $ ) 

 utrinque macula lateral! aureo-tomentosa ; pedibus fulvo-casta- 

 neis, posticis valde elongatis, tibiis longe hirsutis baud scopiferis,

 Bates) . 



Head narrow ; muzzle as in Ph. albitarsis^ moderately elon- 

 gated. Eyes, in male contiguous in front, in female moderately 

 distant. Thorax gradually narrowed in front and slightly 

 constricted at the base. Elytra not reaching the apex of first 

 segment, dehiscent at suture, obtusely pointed at apex ; disk 

 with a few scattered punctures, shining. Antennae rather 

 more than half the length of the body, thickened at the tips ; 

 third to fifth joints linear. The abdomen in the male is very 

 slender and linear, in the female sessile and not disproportioned 

 to the metasternum.
