series of punctures becoming obsolete at the tip. Coxal lines large, extending to the 
hind margin of the first abdominal segment. A good series has been received. 
This insect is closely allied to Cathartus nitidus, Grouv., but is considerably larger 
and more closely punctate. |

Var. concolor, var.n. Prothorace dense punctato, elytris immaculatis. 
Hab. Guatemata, San Gerénimo (Champion). 
This species is distinguished by the peculiar form of the thorax, and the excessively 
dense punctuation of the under surface of the head. The head is short and broad, 
rather coarsely punctate above, with a very distinct acute denticle behind the eyes; the 
antenne are abruptly clubbed, the terminal joint being almost spherical. Thorax 
rather small, the front margin projecting very slightly at each side, so that behind it 
there is a short constriction; the lateral margin finely crenulate, a little narrowed 
behind; the surface somewhat shining, bearing fine and large punctures, and with a 
smooth space along the middle. Elytra pubescent, with regular rows of punctures, 
obsolete behind. Six specimens, no two of which quite agree, and this makes me 
doubtful as to whether the individual from San Gerénimo with densely punctate 
thorax is really distinct.

Hab. Mexico, 'Teapa (H. H. Smith); Nicaracua, Chontales (Janson).— ANTILLES, 
St. Vincent, Grenada °. 
We have received only two examples of this species; it appears to be distributed 
widely in the eastern and western hemispheres, and has been found on board ship. 
It is distinguished from its allies by having the sides of the thorax setigerous.

Mr. Champion found a good series of this species. Iam indebted for its name to 
M. Grouvelle; Reitter’s description is not at all characteristic.
