separate from the Gtli. It ap])ears to me to be correctly 

 placed as Lacordaire has it, and is closely allied to Homo- 

 tropus, above described, agreeing Avith this also in having 

 no membranous border to the elytra. It is the internal 

 claw that is the more slender, not the external, as stated 

 by Blanchard.

 creberrime subtiliter ruguloso ; fronte irregulariter punctu-

 stitiis crebre fortiter rugoso-punctatis ; antennis pallide 

 piceis ; pedibus piceis ; corpore subtus longe piloso. 



Long. 5^ lin. 



This insect forcibly reminds one of some of the smaller 

 MacrophyllcB among the Melolonthidce. 



The elytra are very rugose ; each elytron has several 

 well-marked channels, those on the dorsal region being in 

 pairs with a narrow ridge between them ; the more elevated 

 parts as well as the extreme margin are brown. The 

 clypeus has a slight notch, or emargination on each side.

Meststcechus, gen. nov. 



Mandibles simple, straight on the inner edge, rounded 

 on the outer, concave above. Labrum free, slightly 

 transverse, rounded in front, beset Avitli bristle-like hairs. 

 Mentum elongate ovate, narrowed at the apex, thickly 

 beset with- long stiff hair; palpi short, the apical joint 

 narrowed towards the apex. Clypeus entirely rounded in 

 front, margined. Antennte 10-jointed, the 6th and 7th 

 transverse, the 8th, 9th and lOtli forming a long, stout, 

 slightly-arched club. Tarsi rather long and slender ; the 

 claws subequal, the inner one a trifle shorter than the 

 outer ; the larger claw of the anterior pair split before the 

 apex. 



This genus is closely allied to Amhlyterus, but differs 

 in having the mentum more regularly narroAved in fi-ont 

 and not truncate, and only the larger claw of the anterior
