60 Mr. Charles J. Gahan's Revision of 



Hab. Malacca and Sumatra. Type in Brit. Mus. 



This species agrees pretty closely with A. straminea, 

 Pasc, and A. Jlaviventris, Pasc, both in form and structure, 

 and is chiefly distinguishable from them by the difference 

 in the coloration of the elytra. It is without doubt the 

 species described by Fabricius as Cerarribyx daldorjli, but 

 it certainly is not one of the three forms included by 

 Illiger under that name. Illiger's C. daldorjli seems to 

 have been made up of three very distinct species, his 

 var. 1 being identical with splendida, Fab., his var. 2 with 

 Julgida, Fab., and his var. 3 with nitens, Fab. 



38. Astathes Jlaviventris. 



Astathes Jlaviventris, Pasc, Trans. Ent. Soc. Lond., (3) iii, 

 p. 352. 



Head, prothorax, and scutellum black ; elytra for about one-half 

 or two-thirds of their length from the base, violaceous-blue, and 

 thence to the apex, testaceous ; antennae reddish-brown at the base, 

 pale yellow in the middle, infuscate towards the apex ; body under- 

 neath and legs, piceous or black, with the abdomen, the tarsi and the 

 apices of the tibiae testaceous. Head distinctly, but not very closely 

 punctured in front, more feebly and sparsely punctured on the vertex. 

 Pronotum closely punctured at the sides of the central tubercle and 

 in the transverse grooves. Elytra feebly and somewhat sparsely 

 punctured. 



Hab. Borneo. Type in Brit. Mus. 



This species greatly resembles A. terrninata, Pasc, in size, 

 form and coloration, so much so that specimens of the two 

 species are sometimes mixed up together in collections. 

 But an examination of the character of the centro-dorsal 

 tubercle of pronotum will readily enable one to distinguish 

 them. Another character to be noted is the presence of a 

 rather well-marked depression on the last ventral segment 

 in the female of A. terrninata, and the almost complete 

 absence of any such depression in A. Jlaviventris. 



Genus Anastathes, gen. nov. 



Head almost flat between the antenniferous tubercles. Antenna? 

 rather short and thick, those of the female scarcely reaching to the 

 apical third of the elytra ; third joint not longer than the first ; 

 second joint scarcely longer than broad ; last joint sharply pointed 

 and sub-glabrous at the apex. Prothorax transverse, furnished with 

 an obtuse, transverse tubercle or ridge at the middle of each side, and
