spots ; but the general arrangement of the latter clearly show the specimens to belong 

 to the present species, which may be also known by the sutural stripe, instead of 

 branching off in different directions as in most other species of Calligraphy being of 

 nearly equal width and without any divisions or spots attached to it.

This seems a very widely distributed species, being found in most collections, and is 

 easily recognized by the S-shaped longitudinal subsutural stripe ; from Ventanas and 

 Tuxtla I have several specimens which differ either in wanting the posterior transverse 

 line attached to the S-shaped stripe, or in having the shoulder-spot attached to the 

 latter anteriorly. Besides these differences, some specimens (no doubt immature) are 

 fulvous with a bluish gloss ; others show a more elongate, posteriorly narrowed shape ; 

 but I have no doubt whatever that they are but local forms of the same species. 



20. Calligrapha viginti-maculata, (Tab. XI. fig. 11.) 



Calligrapha 20-maculata, Chevrol. Coleopt. du Mex. 1833 *; Stal, Monogr. Chrys. Amer. p. 285 2 . 

 Hab. Mexico 12 , Orizaba, Cordova (Salle); Guatemala, Capetillo, Cerro Zunil, 

 Duefias (Champion). 



The locality given by Chevrolat and Stal is Mexico only. Mr. Champion has obtained 

 many specimens in Guatemala. The insect is easily recognized by the twenty roundish 

 silvery spots of the elytra ; the latter vary, however, from greenish aeneous to piceous, 

 of which colour I have several specimens from Mexico before me. The shape and 

 colour of the spots are equally variable ; they are either yellow or metallic golden or 

 silvery, while their shape is round, oval, or irregularly angulate ; but their position is 

 always the same.

Of this species I have two specimens before me labelled by Sturm C. maculata. The 

 elytral spots resemble, in their position, those of C. 20-maculata ; but they are smaller, 

 of less rounded shape, and have no punctures, but are smooth and rather convex or 

 raised • the interstices are more strongly punctured and almost rugose-punctate. I also
