new or little known Cetoniidae. 143 



loDij aud slender, very coarsely punctured and strigose, anterior 

 tibiae very narrow aud without lateral teetli; intermediate and 

 posterior tibiae slightly curved, the outer side without any 

 distinct tooth, the inner side sparsely fringed with grey hairs; 

 the inner side o£ the posterior tibiae strongly serrate, the teeth 

 large and acute at the base but decreasing in size towards the 

 apex ; tarsi long, the intermediate ones half as long again as the 

 tibiae. The female differs in being of a rather larger and 

 broader form, more strongly punctured, with the club of the 

 antennae a little shorter, and the abdomen convex in the centre, 

 the legs are shorter and stouter, the anterior tibiae broader and 

 furnished with two large lateral teeth, the intermediate and 

 posterior tibiae, with a strong tooth on the outer side just 

 beyond the middle, and the inner side of the latter are not 

 serrate. Legth 25-27 mm.

This fine and distinct species differs from all other Cetoniidae 

 with which I am acquainted in the peculiar serration of the 

 posterior tibiae of the male, but as I do not consider it advisable 

 to increase the already too numerous genera which have recently 

 been made in some grouj)s of this family, I have referred it to 

 Melinesthes, although the characters of this genus, as defined by 

 Dr. Kraatz, will have to be somewhat modified to admit it. In 

 coloration it is very similar to some varieties of Jf. umhonata,

$ Elongate ; above greenish-blue, shining. Plead coarsely 

 punctured between the eyes, the base and apex sparsely and 

 finely punctured; clypeus a little narrowed in front, the lateral 

 margins very strongly reflexed, apical margin slightly elevated in 

 the centre, apical points rather short aud obtuse ; the margin 

 contiguous to the eyes and two elongate spots near the apex of 

 the clypeus, Avhite; antennae aud palpi pale fulvous, basal joint 

 of the former green. Thorax broadly rounded at the sides, the 

 posterior angles strongly rounded, the base slightly emarginate 

 before the scutellnm, the aj)ex considerably produced over the 

 head, coarsely and deeply punctured, the lateral margins slightly 

 reflexed; a narrow and interrupted marginal band on each side 

 white. Scutellnm with scattered punctures, the apex acute. 

 Elytra attenuate behind, the apex obliquely truncate and
