sat tenuibus, medio fuscis, basi aplceque rufo-testaceis ; 

 thorace Itete rufo ; elytris fuscis, margine a{)icali rufo ; 

 abdomine dense subtiliter punctato, opaco ; pedibus rufis. 

 Long. corp. 2^ lin. 



Antennre moderately long, and not very slender ; the 

 basal joint yellow ; joints 2 — 7 infuscate, 8 — 1 1 yellow. 

 Head obscure reddish ; the clypeus in front acuminate. 

 Thorax very shining bright red. Scutellum reddish. 

 Elytra of a smoky colour, with the hind margin reddish, 

 closely and finely punctured. Hind body very obscure 

 reddish ; the base rather darker than the extremity, very 

 closely and densely punctured, and very pubescent, so as 

 to be quite dull. Legs reddish-yellow, underside dull 

 obscure red. 



A single individual, without special locality. 



Obs. — This species is about the size of the European 

 T. terminalis ; the antennas are of about the same length 

 but distinctly stouter; the front part of the clypeus is more 

 prolonged, and the punctuation of the hind body is much 

 denser. It greatly resembles T. Jlavlcollis, but has the 

 antennas stouter, the clypeus more prolonged in front, and 

 the hind body more densely punctured. 



3. Tanygnathus Jlavicollis, n. sp. Rufescens, capita 

 piceo, antennis apice thoraceque flavis, elytris piceo-rufls. 

 Long. corp. 1§ lin. 



Closely allied to T. riificollis, Kr., and about the size 

 of that species. Antennas slender, rather long; the 1st 

 joint yellowish, the next five darker, the rest paler again. 

 Head pitchy. Thorax bright reddish-yellow, rather broad, 

 of the usual form in this genus, and with the four ordinary 

 punctures. Elytra pitchy ; the suture yellowish at the 

 extremity, about the length of the thorax, closely and 

 finely punctured. Hind body dark reddish, rather closely 

 and finely punctured, and distinctly pubescent. Legs 

 reddish-yellow. 



Tapajos; one specimen, in bad condition. 



ACYLOPHOKUS. 



Up to the present time sixteen species appear to have 

 been described of this genus ; they are from Avidely diffe- 

 rent parts of the globe ; and the species in my collection 

 enable me to state that the genus is probably to be found
