ONCIDERES. 125 
2. Oncideres sparsa. (0. callidryas, 3 var., Tab. IX. fig. 10.) 
Minus elongata, castaneo-fusca, subtus cano-tomentosa, capite thoraceque griseis ; elytris maculis difformibus hic — 
illic confluentibus canescenti-fulvis sparsissime punctatis, punctis basin versus asperato-tuberculatis, 
apicem versus obsoletis; antennis (scapo fusco excepto) rufo-castaneis. 
Long. 73.lin. 
Hab. Mexico, Toxpam (Sailé); Nicaragua, Chontales (Belt). 
The irregular and widely-scattered punctures of the elytra effectively distinguish 
this species from O. callidryas. ‘Towards the base some of the punctures are accom- 
panied each bya small tubercle ; and near the apex they become smaller and shallower. 
The spots of hoary tomentum are more or less tinted with fulvous, and are all of irre- 
gular form, condensing most towards the middle of the sides. 
8. Oncideres tessellata. 
Oncideres tessellata, Thomson, Physis, ii. p. 901. 
Hab. Costa Rica!.—Soutn America, Venezuela. 
The punctuation of the elytra is similar to that of 0. sparsa, but rather denser; 
the tawny tomentum is condensed into round spots, which clothe the elytra from near 
the base to the apex, leaving a large lateral patch of whiter colour.

4. Oncideres albomarginata. (Tab. IX. fig. 12.)

Hab. Muxico, Cordova (Sailé); Nicaraeua, Chontales (Bel¢*)—Sourn AMERICA, 
Venezuela, Cayenne 1. 
In Mexico the species occurs (according to an example in M. Sallé’s collection) in a 
somewhat modified form, the colour being much paler and the white elytral border 
being in consequence less clearly defined.
