 rather larger than the jjreceiling one. and acutely produced

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

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



Group Melolontliidae. 

 Mycernus, gen. nov. 



Body ovate-oblong, slightly convex, not pubescent. Cly- 

 peus deejily emarginate medially. Palpi short ; terminal 

 joint of the maxillary truncate at apex, subseeuriform ; the 

 labial very short. Antenna 8-articulate, rather short ; the 

 club composed of three leaflets, which are not longer than 

 the preceding five joints combined. Anterior tibia tri- 

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

 male, sometimes small. Posterior co.ra 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 

 coxse. Pyyidium exposed, broad, widely rounded. 



Ihe tyi)e bears a remarkable superficial resemblance to 

 Fyronotu festiva, which, however, is well differentiated by its 

 large, conspicuous, intercoxal process. 



Psilodontia is, undoubtedly, the most nearly related genus, 

 but its intercoxal lamina is curved forwards and downwards 

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

 consists of more elongate and somen hat eurvate leaflets. 

 The elypeus is truncate or slightly rounded apically. The 

 eyes are smaller and less convex. All 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 coxae are slender, 

 much eurvate, 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
