longer than broad, the 5th and 6th subquadrate ; the 7th is 

 rather larger than the preceding one, and acutely produced 

 in front ; the three leaflets of the club are of nearly equal 

 length; but they are barely half as long as those of the male. 

 The eyes are large and prominent.

Two mounted males and one female, marked No. 68, were 

 forwarded to me for examination by Mr. G. V. Hudson. 



Group Melolontliidse. 

 Mycernus, gen. nov. 



Body ovate-oblong, slightly convex, not pubescent. C/p- 

 peus deeply emarginate mediall3^ Palpi short ; terminal 

 joint of the maxillary truncate at apex, subsecuriform ; the 

 labial very short. Antenn(S 8-articulate, rather short ; the 

 club composed of three leaflets, which are not longer than 

 the preceding five joints combined. Anterior tibice tri- 

 dentate externally in both sexes, the upper tooth, in the 

 male, sometimes small. Posterior coo'ee with stout short 

 prolongations, these only moderately curved. Sternal process 

 slender and very narrow, horizontal, its front edge vertical 

 and hardly extending forwards beyond the intermediate 

 coxae. Fygidhim exposed, broad, widely rounded. 



The type bears a remarkable superficial resemblance to 

 Fyronotaf estiva, which, however, is well differentiated by its 

 large, conspicuous, iutercoxal process. 



Psilodovtia is, undoubtedly, the most nearly related genus, 

 but its intercoxal lamina is curved forwards and downwards 

 to the breast. Its autennse are dissimilar, and their club 

 consists of more elongate and somewhat curvate leaflets. 

 The clypeus is truncate or slightly rounded apically. The 

 eyes are smaller and less convex. Ail the palpi are longer. 

 Tarsi longer, their 3rd and 4th joints slender at base, 

 whereas in Mycernus the corresponding joints of the anterior 

 are oblong. The appendages of the hind coxse are slender, 

 much curvate, and acute at the extremity, quite hook-like 

 in fact. The pygidiura is only half as broad and almost 

 quite truncate behind. 



Mycernus elegans, sp. n. 



Glossy, brilliant green ; a longitudinal discoidal stripe 

 and an irregular space near each side of the thorax ; the
