- OCHRESTHES. 51 
an assemblage of species closely allied to Clytus, but differing in style of markings and 
colours and in the carinated elytra. The mesosternum is in some species distinctly 
prominent ; and in such cases there is very little distinction from Trichorys; thus 
Ochresthes z-littera is very closely allied to Trichoxys sulphurifer. With Clytus the 
genus is connected through such species as Clytus scalaris. | 
Eleven species are. known. 
1. Ochresthes circuliferus. 
_ Clytus (Ochroesthes) circuliferus, Chevr. Ann. Soc. Ent. Fr. 1860, p. 472.

2. Ochresthes obliquus. 
Clytus (Ochroesthes) obliqguus, Chevr. Ann. Soc. Ent. Fr. 1860, p. 4731. 
Hab. Mexico (Sallé'). 
3. Ochresthes sommeri. 
_ Clytus sommeri, Chevr. Col. du Mexique, 1” cent. fase. 4; Lap. & Gory, Mon. Clyt. p. 72, t. 14. f. 83, 2. 
Clytus tibialis, Lap. & Gory, Mon. Clyt. p. 71, t. 18. f. 83, 3 
Clytus (Ochroesthes) sommeri, Chevr. Ann. Soc. Ent. Fr. 1860, p. 474°, 
Hab. Mexico, near the city}. 
4. Ochresthes citrinus. 
Clytus (Ochroesthes) citrinus, Chev. Ann. Soc. Ent. Fr. - 1860, p- 474: 
Hab. MEXICO. 
5. Ochresthes pollinosus. 
Clytus pollinosus, Chevr. Col. du Mexique, 1” cent. fasc. 4; Lap. & Gory, Mon. Clyt. p. 73, t. 15. 
f. 387 (figura vitiosa). 
Clytus (Ochroesthes) pollinosus, Chevr. Ann. Soc. Ent. Fr. 1860, p. 476°. 
Hab. Mzxtico, Cordova, Orizaba!; Guaremaza, San Gerdnimo, El Jicaro (Champion) ; 
Costa Rica, river Sucio, Caché (Rogers). 
The Costa-Rican examples differ from those of Mexico and Guatemala in the external 
angle of the truncated apex of the elytra being a little more prolonged and pointed.
