Hab. Mexico, Lerdo (Flohr in coll. Bates). One pair only. 
Not closely allied to any other species of the genus known to me. The elytra 
are much shorter than in O. cingulata and O. scitula.

Taricanus truquil (p. 126). 
To the Mexican locality given, add :—Izucar (Sallé), Tehuacan (Hoge).

elongato, angusto. Antenne in ¢ corpore dimidio breviores, in 2 corpore paullo breviores ; articulis 
1° et 3° subtus dense, 4°-11™ multo sparsius, ciliatis, seapo quam art. 3"° multo breviori, gradatim clavato, 
versus basin quam in 7. truquii magis angustato; articulo 3° versus apicem gradatim incrassato,

Hab. Mexico, Jalapa (Hoge). 
A large number of examples. 
Agrees with the very much larger and more robust 7. truqudi in all its generic 
characters except the shorter and somewhat differently thickened and ciliated antenne. 
The essential peculiarities of these organs are, however, the same, the joints being naked 
above and densely ciliated or bearded beneath on the first and third joints.

griseo. 
9. Antenne corpore paullo breviores, articulis 1°-2™ undique dense breviter setosis nec incrassatis, 1° quam 
3** paullo breviori sat graciliter clavato ; 3° et sequentibus subtus breviter ciliatis.

Hab. Panama, Volcan de Chiriqui (Champion). 
One example. 
Lacordaire described his P. rodriguezi from a female example which he mistook for 
the male, which latter sex differs in having a narrower head, more elevated antenni- 
ferous tubercles (penicillated at their apices), and antenne twice the length of the body,
