CALLICHROMA T.ESTACE1PENN1S. 153 



The metasternuni (which is provided with a smooth im- 

 pressed median liue) , the ventral segments , the fore side 

 of the femora and the inner half of the tibiae covered 

 with a fine but extremely dense punctuation, that on the 

 hind part of the femora, outer half of the tibiae and on 

 the tarsi is very sparse. 



The legs are slender and compressed. 



The described specimen was captured by Mr. A. L. van 

 Hasselt in May 1878 in the District of Rawas. 



2. Callichroma (an n. g.) testaceipennis, sp. n. (ƒ. 



This insect appears to be allied to Aromia as well as 

 to Callichroma. It has the inter-antennary ridge and the 

 mandibles shaped as in Aromia but the general appearance 

 of Callichroma. From both genera it dififers by its stout 

 and shorter antennae (extending only a little beyond the 

 apex of the elytra in the male) , by its strongly compres- 

 sed and more elongate posterior metatarsus (almost as 

 long as the following joints taken together) etc. As how- 

 ever the genera of the Callichrominae are as yet only very 

 unsatisfactorily defined , I hesitate to augment the confusion 

 by establishing a new genus for this species , which moreover 

 is easy to recognize. 



Length 33 mm. , that of the antennae 35 mm. ; breadth 

 at the shoulders 9,5 mm. — Metallic green, with shades 

 of cyaneous especially on the base of the antennae and on 

 the legs ; the elytra yellowish-testaceous , with (perhaps 

 accidentally) a somewhat reddish tinge on the basal fourth , 

 their apices narrowly bordered with dark brown ; the front 

 margin of the clypeus , the upper lip , and the tips , inner 

 edges and under surface of the mandibles black; the fore 

 side of the antennae beginning with the tip of the 3rd 

 joint dull black; the hind side of the 5th and following 

 joints with shades of blue or green which however gra- 

 dually disappear towards the end of the antennae. Glabrous , 

 with the exception of the under surface of the thorax
