(Champion, Trétsch). 
Var. 9. Thoracis spinis lateralibus nullis. 
Hab. Payama, Volcan de Chiriqui (Champion). 
The five examples of this variety are more or less abraded and imperfect, but in the 
unabraded parts of the elytra the black spots are seen to be much larger than in the 
Chontales form of D. nivea, chiefly on the lateral margins and on the disc, in the latter 
situation being more or less confluent, and running into short transverse submacular 
fascie. The disappearance of the lateral spine of the thorax in two female examples 
from Chiriqui is remarkable, as it exists in a male from the same locality; in its place 
is an obtuse tubercle. The spine, however, varies in form in the other specimens.
