parallel ; a third joint appears to be indicated by a minute 

 point. 



I can detect nothing to separate the smaller black specimen 

 from the larger one described. Harold's description is very 

 imperfect; but I think there is little doubt that the Museum 

 examples are referable to his species, wiiich is u nearly 

 black variety with the suture of the elytra tinted with green.

Obscure blue, with green reflexions, the thorax darker 

 steel-blue. The head has the two teeth in front moderately 

 separated, the space separating them rounded at the bottom, 

 the margin with a small emargination on the outside of each 

 tooth ; the frontal carina is a little broader than high, with 

 its a]jex arcuate, smooth in front and behind ; the side-piece 

 is divided into two unequal portions by an obtuse ridge 

 parallel to the posterior margin. The thorax has its sides 

 nearly parallel at their middle ; the median line is strongly 

 marked and extends beyond the middle ; the basal impres- 

 sions are distinct ; the punctures on the posterior part oi the 

 disk are very fine and moderately separated, gradually 

 becoming more distinct towards the sides, and in front they 

 are moderately strong; the anterior ridge is very distinct, 

 considerably sinuate on each side of the median projection, 

 which has its angles very slightly raised. The posterior 

 tarsi have the basal joint twice as long as broad, narrowed at 

 its base ; the second joint much narrower, subparallel, a little 

 shorter than the basal joint 5 at the apex of the second joint 

 there is a minute projecting point, which appears to indicate 

 the third joint. 



The female, which I have seen in Mr. Nevinson's collec- 

 tion, differs from the male in having the frontal ridge wider 

 and much less elevated, and the ridge on tiie front of the
