CALOMACEASPIS.— ANTICHIEA. 265 



Apparently an abundant insect in the Province of Vera Cruz. The great majority 

 of the examples are, as Burmeister describes the species, bright metallic green, but 

 individuals occur of a rich reddish-golden hue, with the elytra, as usual, less glittering 

 and golden-green, and others are intermediate between these and the typical state.

In addition to the colour-variations mentioned by Blanchard, the following may be 

 noticed : vermilion with a golden tinge, and head and thorax dark olive-green with 

 elytra vermilion and golden-red round the edges. A specimen from Cuernavaca is 

 figured.

About 80 species of this beautiful and highly characteristic Tropical American genus 

 have been described. Its limits have been left in much uncertainty by authors who 

 have dealt with it ; the grouping of its forms and those belonging to allied genera 

 leading to different results according as the general facies, the size of the scutellum, or 

 the dentition of the tarsal claws are taken as the chief points of distinction ; and the 

 graduation from form to form greatly increases the difficulty. I propose here to limit 

 the genus to those species which have exteriorly bidentate mandibles, a more or less 

 large triangular scutellum, the thorax with truncated or sinuated medio-basal lobe, and 

 the mesosternal process well-developed. The mode of dentition of the tarsal claws is 

 treated as a specific or at most a minor group character.
