Dezscr. Caput mediocre subtrigonum, clypei lobis tribus, duobus lateralibus vix di- 
stinctis, intermedio majori emarginato, angulis anticis paulo productis et obtusis. 
Capitis vertex cornu brevi acuto elevato. Trophi fere ut in precedenti. Thorax 
transversus, abdomine vix latior, lateribus rotundatis serrulatis breviter rufo- 
hirtis, angulis posticis reflexis, disco elevato et in medio impressione lata et 
irregulari antic’ in tuberculos duos rotundatos terminato ; punctatissimus. Ely- 
tra convexa semicircularia, punctatissima ; lineis 6 longitudinalibus leviter sin- 
guloimpresso. Tibie antice graciles, margine externo subsinuato, nec dentato, 
calcari parvo acuto unico terminali. Tibie intermedi extus curvate, serrulate, 
apice paulo dilatato, bicalcarate, calcari interno brevi obtuso, externo elongato 
acuto. Tibie postice elongate fere recte serrulate, calcari unico elongato 
acuto ad apicem interné instructe. Tarsi antici nulli, 4 postici depress! setigeri, 
unguibus nullis. 
Obs. The two insects last above described present such a total diversity of habit and 
form, that unless minutely investigated they would certainly be considered as two distinct 
types of form which ought to be placed widely apart. When, however, we examine 
them in detail, they are found to agree in several very remarkable peculiarities, such 
as the form of the labial and maxillary palpi, the structure of the middle and posterior 
tibie, tibial spurs, and tarsi, so that it is impossible to do otherwise than place them 
in the same genus, although certainly differing far more widely from each other in 
habit than the other groups or types of form of Scarabeus, which are established 
almost entirely upon variations of habit. It must, therefore, be considered a very 
remarkable circumstance, that whilst amongst the Scarabeide in general, the uniformity 
in the structure of the trophi is so great that we find the remark applied to them, 
‘¢Instrumentis in cibariis haud valida patet distinctio,” these two greatly diversified 
forms should possess not only a similarity of organization in these parts, but that this 
organization should be so anomalous ; for it is in vain that we look throughout the 
insect world for labial palpi of a form analogous to that in these two species ; but it is
