60 Mr. C. 0. Waterhouse's descriptions of 



tinctly punctured all over, with no costae nor striae. 

 Pygidium gently convex, moderately thickly and distinctly 

 punctured, very slightly impressed on each side at the 

 margin. Mesosternal process transverse, a little angular 

 in the middle, evenly arcuate in front. The segmentations 

 of the abdomen margined with deep blue. Anterior tibine 

 with two teeth. 



Coptomia rufo-varia, n. sp. 



C. praslnce affinis, viridis, thorace elytrisque rufo-tinctis ; 

 elytris fortiter striatis, pygidio leviter convexo haud 

 impresso, transversim striolato. $ . 



Long. 9 lin. 



Very close to C. prasina, but much narrower, and 

 pale yellowish green, with the thorax and especially the 

 scutellum and dorsal region of the elytra coppery red. 

 Head and thorax less strongly punctured than in prasina. 

 Scutellum more acuminate. Elytra deeply striated, but 

 the punctures in the striae are scarcely visible even with 

 a magnifying power, and there is no fine line at the 

 bottom of the stria, as is usual in prasina ; the first four 

 interstices are straight and equally broad ; the fifth and 

 sixth strige are very strongly punctured, straighter, and 

 nearly of equal length ; beyond these there are two lines of 

 strong punctures besides the marginal one ; the apex is 

 finely striolate, as in prasina. The pygidium is not im- 

 pressed on each side of the disk, but is evenly convex, 

 and although closely striolated, is not so closely as in 

 prasina.
