" In the same regions there is also an uniformity or great equality 

 of temperature, well adapted for animal as well as vegetable life. 

 The exuberance of the latter adds to the humidity of the atmo- 

 sphere, as well by the exhalation of the foliage as by preventing 

 free evaporation from the soil. In the boundless forest and inter- 

 minable jungle there will generally be found a great equality of tem- 

 perature, brought about in consequence of the umbrageous shelter 

 impeding the absorption of heat by day, as it checks the free radia- 

 tion of it at night. It is then, owing to the presence of tropical 

 vegetation, united with moisture, that there arises considerable uni- 

 formity of temperature ; in a word, it is from local causes that we 

 are enabled to explain the reasons why we meet with the repre- 

 sentatives of tropical genera of plants and insects extending into 

 higher latitudes than at first might naturally be expected." 



Sp. 1. Euchlora viridis, Fabricius.

E. glabra, punctata, supra viridis nitens suhtus cupreo-aurala, 

 pedibus cupreis. Sternum hand porrectum.

Httb. in China. 



Varietas E. Elytris cupreo-marginatis, corpora supra ceneo mar- 

 ginato, antennisque piceis. 



This species is found also at Singapore, Assam, in Bengal, and in 

 the island of Ceylon. On the iinder side it is of a rose-coloured 

 copper, appearing about the sternum and the lower rings of the 

 abdomen of a brassy vivid green.

 viride, aureo -opalino colore tinctum, infra viridi-ceneum, pedibus

 Hub. in Java, Mus. Dom., MacLeay. 



" I have received this species from Java ; it varies in size, and may 

 at once be distinguished from E. viridis by its smooth upper sur- 

 face, which is of an opalescent bright green ; its under side is also 

 more brilliant, and of a golden-coloured bronze ; the tibiae and tarsi 

 are invariably green. The E. MacLeaii of Mr. Kirby's MSS. is 

 only a large variety of this species."

 " This insect is closely allied to E. viridis, MacLeay ; it is, how- 

 ever, distinct. Viridis in form is oval. Cvpripes, ovate : the under
