260 Mr. C. O. Waterliouse on Cohoptera 



in the Museum collection that agrees well with the type of 

 repercussa. The specimens labelled repercussa in Capt. Kerre- 

 mans'' collection are males of A. viridis, Kerr. They differ 

 from the type in M. Oberthiir's collection in not having the 

 sutural striae impressed, but striato-punctate. 



A. nurolimbata, Bohera., is a male, and, according to a 

 specimen from N "Garni labelled "compared with type" by 

 Mr. Saunders, is very close to repercussa, but is rather less 

 convex and has tiie dorsal area aeneous green ; the disk of the 

 thorax is rather closely and somewhat strongly punctured. 

 The suture and fii'st and second interstices of the elytra 

 smooth at the extreme base only. The sides are densely 

 punctured, but not transversely rugulose. 



Tlie colour of the elytra, according to description, should 

 be cyaneous. 



A female received from N'Garai with the above-mentioned 

 male is green, and, as is usually the case, is less punctured 

 on the elytra, the sutural interstices being smooth for half 

 their length. 



I am inclined to believe that aurolimbata may be only a 

 variety of repercussa, of which viridis is the female. A. fossi- 

 coKis, Harold, may also perhaps be female of the same. 



A. gabonensis, Th., is a female. I could not find any 

 specimen in the Museum to agree quite with the type. The 

 type has the thorax rather narroM'cr than is usual in viridis, 

 the disk is finely punctured, and the median furrovr less 

 marked. It may be an extreme variety. 



Acmaodera poslicalis, L. & G. 



A. postica/is. L. & G., the type of which, by the kindness 

 of M. Oberthiir, I had the opportunity of examining, is a 

 female. It resembles a small A. viridicenea, but is, I think, 

 nearer A. viridis, Kerr., the elytra having the interstices 

 carinulate at the apex. A specimen in the Museum is 

 entirely violet. In the type the violet colour and green 

 shades are irregular and, I should imagine, not natural. 



It may be an extreme variety of viridis. 



Acmaodera fascigera, Harold. 



The sexual differences are not so striking, but the males 

 have the base of the elytra very dark. 



Acmceodera Klugii, Saund. 

 The sexes of this species are alike.
