Probably no insect described by my much valued friend Mr. Kirby 

 more strongly evinces his peculiar tact in establishing sound genera 

 than the subject of the present monograph, viz. Mimela. From his 

 own account in the 14th volume of the Linnsean Transactions, he 

 purchased this insect with a lot of Brazilian species, and at first 

 ranged it with Areoda, its general habit and aspect resembling a 

 tropical American type : meeting, however, afterwards with several 

 other specimens in a Chinese collection, he was induced to examine 

 it more closely, and the result of these observations was embodied 

 in his valuable paper in the Linnsean Transactions, in which he 

 proves distinctly that many of the characters of Mimela appear as if 

 borrowed from South American ty2)es, while its most essential ones 

 a]5proach nearer to Euchlora, the Asiatic type. Many entomologists 

 would, therefore, have rested contented with arranging it along with 

 Euehlora, as the French do at the present moment. Not so, how- 

 ever, Mr. Kirby ; he immediately formed it into a sub-genus, and 

 added the preceding ample characters. 



The distinguishing characters of Mimela appear to be the shape 



* (Mr. Kirby's specimens appear to have been destitute of the four anterior tarsi. 

 They differ from the posterior pair, as described by Mr. Kirl)y, in having one of tlie 

 claws on eacli of these four legs bifid. — F. W. H.)
