testaceous, the posterior femora, as well as the anterior and middle 

 femora, black, and the tibiae, especially the anterior pair, black to a 

 greater extent. 



Hah. West Borneo, Pontianak. In coll. Oberthtir and 

 in Brit. Mus. 



Astathes huhenthali y Heyden (Abh. Sencken. nat. Ges., 

 xxiii, p. 578 (1897), from Samarinda in East Borneo, seems 

 to be identical with this variety. It is described as being 

 closely allied to A. posticalis, Thorns., but differing as 

 follows : elytra violaceous to a greater extent (for four- 

 sevenths of their length from the base) ; front tibiae 

 wholly, and the middle and hind tibiae in their basal part, 

 black ; abdomen rufous ; central tubercle of pronotum 

 strongly raised (" thorace in medio postice alte calloso "). 

 These differences, with the exception of the last, are almost 

 precisely the same as those by which the above variety 

 may be distinguished from posticalis; but there is no 

 appreciable difference in the size or form of the pronotal 

 tubercle, and it is therefore possible that Hey den's species 

 may be one of the varieties of A. terminata, Pasc. instead. 

 In none of these varieties known to me, however, are the 

 front tibiae black to a greater extent than those of the 

 other two pairs ; as a rule, they are less black. 



31. Astathes purpurea. 



Astathes purpurea, Pasc, Trans. Ent. Soc. Lond., (2) iv, p. 

 108 (1857) ; id. (3) iii, p. 354. 



Head and prothorax black and glossy ; the underside and legs 

 pitchy-black, but with the hind-breast, the tarsi, and apices of the 

 tibiae testaceous ; elytra entirely of a dark purplish or violet colour ; 

 first three joints of the antennae brownish, the remaining joints pale 

 testaceous. Front of head distinctly but not very closely punctured ; 

 furnished with a rather feeble median carina in its lower part in the 

 female ; vertex of head and disk of prothorax sparsely punctured ; 

 centro-dorsal tubercle of prothorax feebly raised, slightly notched in 

 the middle behind, and impressed with a shallow pit in front. 

 Elytra relatively rather narrow, sparsely but rather strongly 

 punctured ; each with a juxta-sutural and two dorsal costae. 



Hah. Singapore. Type (?) in Brit. Mus. 



This species somewhat resembles A. caloptera, Pasc, in 

 general coloration, but differs in having the tarsi and 

 hind-breast testaceous instead of black ; and is further to
