52 Mr. Charles J. Gahan's Revision of 



This variety differs so slightly from the type as to make 

 it extremely probable that the type itself came from 

 Borneo or Java, and not from Japan as stated by Thomson. 

 No other specimens of this or of any species of Astathes 

 have been recorded from Japan. The species is very 

 closely allied to A. instabilis, the only definite character 

 by which it is distinguishable being the presence of 

 numerous tawny setae on the anterior violaceous area of 

 the elytra, causing the latter to exhibit a somewhat golden 

 gloss in certain lights. 



24. Astathes montana, sp. n. 



Head, prothorax, underside, femora, and base of antennae, reddish- 

 testaceous ; vertex of head and two small spots on the pronotum faintly 

 piceous, intermediate joints of antennae pallid, last joints infuscate : 

 elytra of a deep violaceous-blue colour, except at the extreme apical 

 border where they are rufescent ; all the tibiae, and the posterior face 

 of the front femora blackish. Head distinctly but rather sparsely 

 punctured, with the interstices between the larger punctures on the 

 front minutely punctulate ; prothorax sparsely punctured on the 

 centro-dorsal tubercle, in the channel in front of it, and on the lateral 

 tubercles ; elytra sparsely punctured from the base almost up to the 

 apex. 



Long. 12, lat. 5 mm. 



Hah. Himalayas (Melly). Type ($) in Brit. Mus. 



In coloration this species resembles A. violaceipennis, 

 Thorns., but differs in having the tibiae entirely black. It 

 is distinguished further from that species in being less 

 densely setose, and having the centro-dorsal tubercle of 

 the prothorax less raised, and without a pit on each side 

 in front. 



25. Astathes velata. 



Astathes velata, Thorns., Syst. Ceramb., p. 557 (1865) ; 

 Pasc, Trans. Ent. Soc. Lond., (3) iii, p. 353. 



Yellowish-testaceous j with the last five or six joints of the antennae 

 infuscate ; and the elytra from the base almost to the middle, 

 violaceous-blue, but with this violaceous-blue area more or less widely 

 interrupted at the suture by a triangular extension forwards of the 

 testaceous area. Centro-dorsal tubercle of the prothorax feebly 

 raised, appearing as little more than the median portion of a sinuate 

 ridge crossing the pronotum from side to side ; but w T ith the anterior 

 slope of the tubercle extending to the transverse groove in front and 

 raised slightly above its level so as to interrupt it.
