266 On Coleoptera of the Family Buiircstidse. 



Long. 24 mm. 



Hab. Andaman Islands (/?. Meldola). 



Differs from D. gratiosa in having the elytra dark green 

 and the pale green of the suture restricted to the extreme 

 base, &c. It differs from D. Bowrbujii in being smaller, 

 in the colour of the elytra, and in having the apex bright 

 pale green instead of coppery. 



It is worthy of notice that this form is nearer to the Hima- 

 layan D. Boivringii than to D. gratiosa from Penaug. 



Chrysochroa Fivhstorferi, sp. n. 



Form and arrangement of colour as in C. rugosicoUis, 

 Saund. Head and thorax very dark, obscure purple, the 

 lattej' slightly cyaneous on the disk, rather closely and 

 strongly ])unctured, the sides rugose. Elytra very pale 

 yellow, the basal half of the margin, a large somewhat 

 triangular patch before the middle, and the apical third 

 nearly black, the extreme apex tinted with aeneous. Sternum 

 purple ; abdomen bluish tcneous. ^ ? . 



Long. 42-50 mm, 



Huh. Tonkni (//. Fruhsforfer). 



Specimens of this species were received with the name 

 7'vgicollis, Saund , attached. I think, however, that they are 

 distinct. In addition to the difference in colour it is distin- 

 guished by being less elongate, and the thorax shorter and 

 broader. This is particulaily noticeable in comparing the 

 males. 



Chrysochroa viltata, Fabr. 



C. vittata, F., is allied to C. ocellaia, F., and not to 

 C 67/i?yew6iA', witli which it is so often associated in collections. 



C vittata, ocellota, falgens, similis, and Ludekingii form a 

 group having the thorax somewhat constricted in front and 

 the elytra emarginate at the apex. 



Chrysochroa unidentata, Fabr. 



I think the synonymy of this species, as given by Capt. 

 Kerremans' list in Wytsman^s 'Genera,^ p. JS, is not quite 

 correct. C. marginata and C. sublineata should be associated 

 with C. mutubiiis. The true C. unidentata has the thorax 

 dark coppery, with two well-defined green vittaj. 



Chrysochroa Thelwalli, sp. n. 

 Head coppery. Ihorax golden green, with a jjuiplc
