Encya cribrata, n. s. 



Praecedenti affinis, sed paulo latior, picea, confertim 

 ruguloso-piinctata; abdomine creberrime punctato, sqiia- 

 mulis angustissimis pallidis tecto. <? . Long. 9 lin., 

 late 4f lin. 



Uniform dark brown. Head and clypeus very strongly 

 and very closely punctured. Thorax much narrowed in 

 front, not much narrowed at the base, the sides rounded 

 behind the middle ; punctuation strong and very much 

 crowded. Scutellum very thickly punctured. Elytra 

 densely punctured, but the punctures are of unequal size ; 

 here and there are small, irregular, smooth intervals. 

 Abdomen rather thickly and moderately strongly punc- 

 tured ; clothed with pale short setae, or extremely narrow 

 scales. Basal joint of the antennae long ; the second 

 very short ; the third distinctly longer than the second ; 

 the fourth about as broad at the apex as long, with a 

 slight angular projection on the inner side ; the six apical 

 joints forming a rather long straight club. 



EUTRICHESIS, n. g. 



Clypeus very transverse, sej)arcited from the forehead 

 by a well-marked carina. Third and fourth joints of the 

 antennae subequal ; the club small, ovate, composed of 

 three lamellae. Mesosternum without intercoxal process. 

 Anterior tibiae with two strong teeth. Metathoracic para- 

 pleurae long and narrow. Claws furnished beneath in the 

 middle with a strong tooth. 



I propose this genus for some species of large size, with 

 the body clothed with a mixture of shorter and very long 

 hair. Although the large size of the species would lead 

 one to look for these insects among true Melolonthidce, 

 they should certainly, on account of the narrow para- 

 pleura, be placed ^'lihihQ RMzotrogiiKB, near Schizonycha. 



It appears to me that TricJiolepis, Blanch., which 

 Lacordaire " has no hesitation in uniting with " Lepi- 

 diota, would be better transferred to the RMzotrogiiKB, on 

 account of the narrow metathoracic parapleurae. Melo- 

 lontlia lactea, Gory, Leucopholis lepidota, Klug, Melolontha 

 grandis, Cast., and Lepidiota Savagei, Hope, are Melo- 

 lonthidce, and must for the present be put in the magazine 

 genus Lepidiota, and not under Tricholepis, as in Gem- 

 minger and v. Harold's Catalogue. Enthora has narrow
