Var. The upper surface dull bronze-black, with a greenish or bluish lustre; the elytra moré ‘sparsely. 
punctured, the interspaces sometimes irregularly raised. 
Hab. Nicaragua, Chontales (Janson); Panama, Volcan de Chiriqui (Champion). 
With a long series of specimens it is impossible to separate 7. cwruleopunctata from 
T. casta, the types of which are before me. Typical 7. cw@ruleopunctata have the 
elytra more sparsely punctured and the interspaces less coriaceous, but intermediate 
forms occur. The colour is variable, as is also the length of the humeral process of 
the elytra. Of the variety two specimens only have been seen. T. cewruleopunctata is 
doubtfully recorded by Boheman ? as from New Orleans, which is evidently a mistake ; 
the specimen in the Baly collection named by him? is from Guatemala. Fig. 13 is 
taken from the type of 7. casta, fig. 14 from that of 7. ceruleopunctata.

Var. The upper surface dull brassy-cupreous, the punctures golden-green at the bottom. 
Hab. Mexico, Minatitlan (Hoge). One specimen. 
This insect is much more shining than 7. casta, and it has the prothorax as well as 
the elytra coarsely punctured, the punctures on the elytra much more numerous. The 
single specimen from Costa Rica has the humeral process more elongate, and the 
suture more raised below the base. The locality quoted by Chevrolat ! is ‘ Toulepeck.”

Tauroma, subg. Desmonota, Chapuis, Gen. Col. xi. p. 374. 
One species only of this genus, which contains some familiar and abundant Brazilian 
insects, is known to me as yet from within our limits. Desmonota is sunk by Chapuis 
as a subgenus of Zauroma. It is exclusively confined to Tropical America, just 
entering our southern limits.
