The above insect seems to be rather abundant in Ceylon, 
numerous specimens having fallen under my notice, but those 
with highly-developed mandibles appear to be scarce. In Sir 
Emerson Tennant’s History of Ceylon, i. 27, Cat. of Coleop., the 
name Cingalensis is misprinted Bengalensis: in the same work, the 
genus Singhala (sp. tenella, Blanchard), belonging to the family 
of the Rutelide (vid. Cat. Coll. Mus. Hist. Nat. Paris, part 2,” 
p- 198), is erroneously placed with the Lucanide.

A new species from Ceylon, in the collection of Count Mniszech. 
According to M. Henri Deyrolle, closely allied to O. Cingalensis ; 
a description will shortly appear in the Ann. Soc. Ent. de France. 
It will form, together with O. Cingalensis and O. @ratus, the third 
section of the genus Odontolabis, having elongate mandibles, but 
the head, instead of being armed with a spine behind the eyes, 
is only slightly inflated, the body depressed and highly polished, 
and the anterior tibiz are curved. The sub-genus Calcodes of 
Westwood (vide Hope’s Catalogue) is incorporated with this sec- 
tion, the metallic colour of Calcodes e@ratus forming only one of its 
chief characters,

Genus (vel sub-genus) novum inter Anoplocnemum et Odontola- 
bidem collocandum. Caput maribus magnum, transverso- 
quadratum, lateribus pone oculos haud tuberculatum, margine 
antico fere recto, clypeo in tuberculum parvum porrecto. 
Antenne clava tripartita. Mandibule maribus dente parvo 
sub-apicali intus armate. Maxille in utroque sexu inermes. 
Prothorax transversus, lateribus inermibus, parallelis, angulis 
posticis rotundatis. Tibie anticee extus 4-dentatze, mediz et 
posticee inermes. Elytra brevia, ovata, haud striata. 
This new and interesting sub-genus approaches most nearly to 
Odontolabis, but the insects in that group have the head deeply 
emarginate in the middle of the anterior margin, as well as armed 
with a strong spine on each side of the head behind the eyes ; and the
