 emarginatc: thorax very uneven, U indistinctly crenate.l. with ■ <]• , , 



forming a semicircular lobe at each angle behind: the posterior margin v« rv com«\.

with innumerable little black but:. f large shining hi 



having a faint channel on each, with lines of smaller buttons between them and round 

 the costal margin, and 2 more regular rows un either nde of the suture .- 

 with 2 minute indistinct teeth on the outside near the middle, the other* mi. 



This insect, from Valparaiso, might be mistaken for a large tpectmen of the 

 following, but it is readily distinguished by the hinder thoracic angle* not 

 being- excised. 



67. Trox pilularils, Germ. Coleopterorum Specit r, vol. i. p. 1 1.;. 



From Rio Janeiro, but apparently not abundant : the 1 lines of buttons on 

 the elytra are large and very elevated. 



*68. Trox lachrymosus, Curt. 



Cinereus nigro mixtus, thorace parvo insequali, elytris amplis elongato-ovati-- 



punctato-striatis lineis 4 tuberculorum magnorum 5 parvonnn Dotal 

 Length from 5 to 6 lines, breadth from 3 to 4. 



Ash-coloured, the elevations black; head and thorax punctured: clypcus not large, with a 

 thickened margin and 2 raised oval tubercles on the crown : thorax small, 1 li- 

 as well as the clypeus edged with short black hairs, the base slightly produced at the 

 scutel ; 2 large elevations near the disc with a little pit in each, one on either side, and 

 4 along the base : elytra nearly twice as broad and 4 times as long as the thorax, the 

 buttons not very elevated : stria? of elytra punctured, and between them, except at the 

 outer margin, are 4 lines of large and 5 of minute black shining buttons, and there are 

 2 large humeral elevations : anterior tibiae 6hort and slightly sinuated outside. 



This species is common at Valparaiso, and is similar in form and propor- 

 tions to T.suberosus, Fab. ; the small thorax, punctured elytra, with the costal 

 margin free from buttons, and above all the large higli and bare should- 

 distinguish this species from its congeners.
