Notes on Table. 



B. In this Group the prothorax is very decidedly wider 

 at the base than at the apex, the increase beinsf often quite 

 regular. In BB the prothorax is occasionally slightly wider 

 at the base than at the apex, but the sides are always incurved 

 near the base, so that the apparent width is less conspicuous. 



B. d. Nearly all species of the genus have more or less 

 conspicuous setae, but in these species the setae are longer and 

 erect, not depressed; eonfinis has erect seta 3 , but they are 

 shorter than those of d . 



B. mm. To decide this character the head must be viewed 

 from the side. 



B. nn. In these species the base of the prothorax is 

 almost equal to the base of the elytra, but as their shoulders 

 are rounded, the sides behind them are somewhat wider. 



B. r. This character, although not mentioned in the 

 original description, is quite distinct on a co-type in the 

 Museum ; the depressions are distinct towards the sides, but 

 are not continued across the disc. 



B. ,<?. In these species the setae, although decidedly shorter 

 than in d, are of such a nature that their tips do net rest 

 upon the scales, whereas in $s they rest upon the scales 

 throughout their length. In aphthosus, however, a few of 

 the setae are not entirely depressed. 



y. For the purposes of this table, the rostrum is held to 

 commence at an imaginary line touching the front of the eves. 



F. i. The bisinuate lateral outline is not here referred 

 to, nor the feeble transverse impressions that sometimes accom- 

 pany same. 



F. j. Specimens of many species of the genus have the 

 head protruded beyond the prothorax more than it should be, 

 the extra space being glabrous ; but in these species the 

 squamose portion only is considered. In melvittensis the eyes 

 almost touch the prothorax ; whilst in mgicollis they are some- 

 what distant from it. 



F. o. On the muzzle of cyrtops there are a few green 

 scales. 



Myllocerus modestus, Pasc. 



niveus. Lea. 



In preparing the table given in the present paper I had 

 occasion to carefully compare the type of nireus, with two 

 co-types of modestus, and found that they belong to but one 

 species. 



Myllocerus foveiceps. Lea. 



At the time that this species w T as described I had seen 

 but two specimens, and these were probably bleached. There
