Scarabus Lkssoni, Blainville, Diet. Sci. Nat. pi. 48. fig. 32; 

 Lesson, Voy. de la Coquille, vol. ii. p. 334. pi. 10. fig. 4. 



Auricula Petiveriana, var. Deshayes. 



S. testd ovatd, longitudinal iter substriatd, rufo-castaneo varie- 

 gatd ; spird lateribus concavis ; aperturd oblongd, spird lon- 

 giore ; labio subplano, labro postice arcuato. 

 Hab. New Ireland ; Hinds. (Mus. Cuming.) 

 The oval form and oblong mouth render this species easily distin- 

 guished from S. imbrium : the upper tooth on the inner lip is longer, 

 and two of the five teeth in the outer lip are more prominent than 

 the others.

 Hab. Borneo ; Cagayan, province of Misamis ; Mindanao ; in

Scarabus trigonus, Troschel, Wiegmann's Archiv, 1840.

The triangular form, approaching that of Tomogerus, at once di- 

 stinguishes this species : the middle tooth on the inner lip is double, 

 the upper tooth prominent : there are five teeth in the outer lip, two 

 being more prominent than the others.
