88 On the Dynastid Genus Loncliotus. 



Hah. N. Madagascar. 



The species is represented by a single male specimen in the 

 British ^luseum collection. It is about the size of L. crassus, 

 but relatively broader and shorter. The prothorax is irregu- 

 larly punctured and has smooth areas at the middle of the 

 base and sides. The hind angles are almost right angles. 

 The thoracic cavity is about as broad as it is long, reaching 

 to near the base, and, as in all the species except L. crassus, 

 is produced into two points on each side. The elytra are 

 closely and very coarsely punctured, the punctures not 

 forming distinct lines. The propygidium is produced and its 

 stridulatory strise are fine and close, with a still more finely 

 sculptured area on each side.

Hah. N. Madagascar : Nossi Be. 



There are two male specimens in the British Museum. It 

 is a compact globose species, differing from all the rest by the 

 form of the mandibles, which arc very prominent externally 

 and not distinctly lobed. The pronotum is very strongly and 

 deeply punctured, without smooth spaces. The scutelluni is 

 not quite smooth, but bears an angulate line of rather con- 

 fused fine punctures. The elytra are coarsely and irregu- 

 larly but not very deeply punctured, and tiie propygidium 

 bears very fine stridulatory strias which extend without inter- 

 ruption across the whole median part. The thoracic cavity 

 of the male extends nearly to the hind margin and is wide 

 and deep.
