22. Astathes instdbilis, sp. n. 



Head, prothorax, body underneath, legs, and antennae testaceous ; 

 fourth and fifth joints of the antennae pallid, and the last three or 

 four infuscate ; tibiae sometimes more or less blackish ; elytra 

 violaceous-blue, except in the apical fifth or sixth part, which is 

 testaceous. Head sparsely punctured above, more closely in front, 

 with the interstices minutely punctulate. Pronotum strongly but 

 sparsely punctured ; the central tubercle almost as strongly raised as 

 in A, levis, Newm. Elytra sparsely punctured ; each with two 

 distinct dorsal costae in addition to an acute costa lying close along- 

 side the suture ; the setae on the violaceous area black, those on the 

 apical testaceous area, tawny in colour. Antennas of the male a 

 little longer than the body, those of the female reaching to the apical 

 fifth of the elytra. 



Var. 1. Elytra entirely testaceous, and the setae on them all tawny 

 in colour. 



Var. 2. Elytra testaceous ; with the setae mostly black in colour, 

 those only near the apex being tawny.

23. Astathes japonica. 



Tetraophthalmus japonicus, Thorns., Archiv. Ent., i, p. 51 

 (1857). 



Head, prothorax, body underneath, legs, and base of the antennae, 

 testaceous ; intermediate joints of the antennae pallid, the last four 

 or five infuscate ; elytra violaceous, except in their apical sixth part 

 and for a short distance forwards along the sutural and lateral 

 margins, rather closely beset with tawny setae, especially at and in 

 front of the middle so that a faint tawny band becomes visible there 

 in certain lights. Head sparsely punctured above, more closely in 

 front, with the interstices minutely punctulate. Pronotum sparsely 

 punctured. Elytra distinctly, but not closely, punctured from the 

 base almost to the apex ; each with two acute dorsal costae in addition 

 to one running alongside the suture. Antennae of the male a little 

 longer than the body. 



Hal. (?) Type {$) in coll. Oberthiir. 



Var. Apex of elytra more narrowly testaceous than in the type ; 

 middle and front tibiae, and sometimes also the hind tibiae, blackish.
