black underside and legs distinguish this species well from B. mirabilis. The punctua- 

 tion of the elytra also is quite different. Two specimens were obtained, one of which 

 is figured.

Hab. Guatemala, Las Mercedes, Mirandilla {Champion); Nicaragua, Chontales 

 (Janson, Belt, Salle); Costa Eica 1 , Volcan de Irazu, Cache (Bogers). 



The specimens which are before me from the above localities are no doubt to be 

 referred to Stal's species, with which they agree in every respect according to the author's 

 description. The insect is of large size, above either metallic green or blue, but 

 without much gloss, each elytron having two fulvous transverse dentate bands, two 

 spots at the base, and another at the apex. The bands are either entire or separated 

 into spots. The thorax in the male insect is dilated and broader than the elytra. A 

 specimen from Nicaragua is figured. 



17. Doryphora decemstillata. (Tab. xiv. fig. 21.) 



Doryphora decemstillata, Stal, Diagn. 1858, p. 254; Monogr. Chrys. Amer. p. 39 ] . 



Hab. Mexico 1 , Cordova, Santecomapan, Cosamaloapam (Salle), Cerro de Plumas 

 (Hoge); Guatemala, Senahu (Champion). 



This large-sized species is easily known by its uniform dark greenish or bluish colour 

 and the ten fulvous spots on the elytra. A single specimen was received from Guatemala, 

 which differs from the Mexican forms in its more finely punctured elytra and thorax, 

 but agrees in all other respects. The figure representing the insect is too short, and 

 the last spot at the apex of the elytra is absent. 



18. Doryphora princeps.

Hab. Mexico 2 , Cosamoloapam (SalU) ; Beitish Honduras, river Sarstoon (Blanca-

This large and handsome species is a most variable one in regard to coloration as 

 well as to its sculpturing, which induced Stal to separate, as specifically distinct, his 

 B. magnifica, in which the entire disk of the thorax is greenish aeneous, and the elytra 

 rugose-punctate. I have, however, many intermediate forms before me, in which the 

 two bands of the thorax show all intermediate degrees of distinctness, from being well 

 separated to becoming united, the sculpturing of the elytra being equally variable, so
