IYG: Mr. H. W. Bates on the 



2. Phygojjoda suhvesfita, White. 



Odontocera suhvestita, White, Cat. Long. Col. Brit. Mug. p. 190. 



K. Tapajos, Amazons. 



This species would be almost equally well placed in the 

 genus Chan's, sect. II. The hind thighs are longer and rather 

 more abruptly clavate than in any species of Chans, but they 

 are less so than in Phi/goj^oda alhitarsis. 



AcOEETHRA, nov. gen. 

 Corpus, praecipue abdomen valde elongatum. Caput parvum, rostro 

 paululum producto. Oculi c? magni antice fere contigui, 5 

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

 tatis, serratis. Thorax parvus, antice angustatus. Ehjtra cunei- 

 formia, obtusa, abdominis segmeuti primi medium attingentia, 

 disco nitida. Pedes postici elongati ; femora gradatim clavata ; 

 tihice haud scopiferse ; tarsi breves. Metasternum baud distentum; 

 abdomen S liueare, gracile, $ sessile. 



This genus is closely allied both to Charis and Phygopoda^ 

 but cannot be united to either without rendering their defini- 

 tion impossible. The simple hind tibiaj and obtuse cuneiform 

 el^^tra distinguish it from Phygopoda ; and the elongated hind 

 legs and abdomen separate it from Charis. The abdomen is 

 of disproportionate extension, exceeding by one half the length 

 of the rest of the body. 



Acorethra chrysaspis, n. sp. 

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

 lato-punctatis ; elytris cuneiformibus, disco pallide fiiscis politis, 

 macula utrinque scutellari scutelloque aureo-tomentosis ; pectore 

 aureo-tomentoso ; segmento primo ventrali testaeeo, caeteris ( $ ) 

 utrinque macula laterali aureo-tomentosa ; pedibus fulvo-casta- 

 neis, posticis valde elongatis, tibiis louge hirsutis haud scopiferis, 

 femoribus gradatim clavatis, basi pallidis. Long. 5-7 lin. c? 5 • 



Novo Friburg, Eio Janeiro {coll. Dr. Baden and H. W, 

 Bates). 



Head narrow ; muzzle as in Ph. alhitarsis, moderately elon- 

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

 di.stant. Thorax gradually naiTowed 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. Antennas 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.
