1. Jamesia glohifera, Fab. 



Lamia globifera, Fabricius, Syst. Eleuth. ii. 284. 15. 

 Hypselomus variolosus, Pascoe, Trans. Ent. Soc. n. s. v. pt. 1 (1859). 

 J. subelongata, sordide griseo-brunnea ; thorace transverse niguloso 

 et acute tuberculato ; elytris prope basin tuberculis globosis nigris 

 politis et postice maculis nigris leviter impressis variegatis ; capite 

 lateribus parallelis, oculis magnis, subquadratis ; antennis brun- 

 neis, maris corpore multo longioribus ; pedibus simplicibus. Long. 

 10 lin. 



Not uncommon on dead trees throughout the Amazons region ; 

 also found at Cayenne. 



2. Jamesia pupillata, Pascoe. 



Hypselomus pupillatus, Pascoe, Trans. Ent. Soc. n. s. v. pt. 1. 

 Jamesia bipunctata, Jekel, Journ. of En torn. i. 260. 



J. subelongata, parum convexa, olivaceo-brunnea, nigro punctata ; 

 elytris medio utrinque ocellatis ; maris capite infra dilatato, corni- 

 bus frontalibus magnis acutis porrectis ; antennis quam corpus 

 duplo longioribus. Long. 1 1 lin. c? $ . 



Differs from J. globifera chiefly by the more depressed form 

 of the elytra, and the absence of basal elevation with globular 

 tubercles. It may readily be recognized also by the eye-like 

 spot on the disk of each elytron, consisting of a rounded, black, 

 slightly impressed spot, surmounted by a white speck. The 

 antennae are much more elongated, and the projecting angles of 

 the antenniferous tubercles in well-developed males are very 

 large and acute, and are directed horizontally. The base of the 

 elytron has a few minute granulations with punctures, and the 

 rest of the surface is sprinkled with rounded, dark-brown, 

 slightly impressed spots, as in /. globifera. 



Ega; not uncommon. 



Genus Hesycha (Dj. Cat.), Thomson. 



Thomson, Archiv. Entom. i. 187 (1857). 

 Fairmaire, Ann. Soc. Ent. Fr. (1859), p. 623. 



This genus was first characterized, in few words, by M. Thom- 

 son in 1857 ; but the description subsequently published by 

 M. Fairmaire defined more accurately its points of distinction. 

 It agrees with Hypselomus in having the first joint of the an- 

 tennae abruptly clavate, and the third joint curved ; the curva- 

 ture, however, is much less pronounced than in Hypselomus, 

 and is sometimes very slight. Its other distinguishing charac- 

 ters are (1) the elongate, parallelogram mical, and depressed 

 form of body, (2) the more elongated claw-joint of the tarsi, 

 and (3) the wide separation of the antennae at their origin.
