strife are evanescent posteriorly and scarcely reach the 

 middle, the interstices are punctulate and there is a shallow 

 impression, somewhat transverse, on either side before the 

 middle ; the propygidium has four fovese similar to those of 

 N. iinpressicollis, Lew. (fig. 1^ Proc. Ent. Soc. Lond. p. 335, 

 1885), and the pygidium has two fovese resembling those of 

 N. furcatus, Lew. [1. c. fig. 15) ; the prosternum is parallel 

 laterally, with marginal striae which join at the base but are 

 a little shortened in front ; the meso- and metasterna have a 

 median canaliculation common to both segments, the latter 

 is marginate laterally ; the legs are reddish brown. 



In its rather robust form this species most resembles 

 iV. Andrev)esi, Lew. ; it is the only species at present 

 known that has a frontal stria.

Eutidium lepidum, sp. n. 



Ovato-latum, depressum, nigrum, nitidum ; fronte plana, obsolete 

 bistriata, striis brevissimis ; pronoto impunctato ; elytris stria 1* 

 brevi, coeteris nullis ; propygidio fere impunctato ; pvgidio sparse 

 et minute punctate. 



L. 5| mill, (absque mandibulis). 



The wider and more depressed form of this species distin- 

 guishes it from the other three known of the genus. Also 

 the absence of any long elytral stria, almost impunctate pro- 

 pygidium, and the sparse and equally scattered fine punctures 

 of the pygidium are characteristic of E. lepidum, and there 

 are faint indications of frontal striaa such as are observable in 

 Hololepta aradiformis, Er.

Hololepta dux, sp. n. 



Oblongo-ovata, subparallela, depressa, nigra, nitida ; fronte Isevis- 

 sime striata ; thorace S foveolato, angulo antice baud producto ; 

 elytris stria 1* appendice recta ; propygidio pares circum, pygidio 

 dense, punctato. 



L. 15 mill, (absque mandibulis). 



Oblong, oval, somewhat parallel laterally, depressed, black 

 and shining ; the bead is feebly impressed anteriorly with 

 two extremely fine curved frontal striae, which apparently 

 meet behind the middle of the mentum ; the thorax is 

 sparsely punctured at the sides, somewhat acute at the anterior
