forwardly directed parts of the scars are much more, and the other parts less, deeply impressed 

 than in either. The lateral areas of the metasternum are somewhat smoother and the 

 prcnotum and elytra somewhat more convex than in either. 



Gonatas schellongi, Kuwert.

 Gonatas schellongi, Kuwert, 1898, p. 314. 



Numerous specimens from New Guinea (Stephansort, Milne Bay, Humboldt Bay, 

 Torres Straits), Kei Islands, and New Brittain (Herbertshöhe). Length 28-32 mm. 



The antennal lamellae are longer than in the two preceding species, and the posterior 

 margin of the mentum is more strongly curved, the scars consequently forming a W- rather 

 than a &>-shaped figure. The left mandible is as broad as the right and scarcely if at all 

 longer ; its anterior lower tooth is less distinct than in G. minimus, but more distinct than 

 in other species of the genus. The form of the outer tubercles varies slightly, and 

 G. tridentatus, Kuwert, is unlikely, I think, to prove distinct ; G. differens, albertisi, major 

 and novaebrittanniae will perhaps also prove to be identical with the present species. The 

 lateral areas of the metasternum are punctured and hairy. The dorsal grooves of the elytra 

 are less distinctly punctured than are the lateral ones.

Gonatas germari, Gravel)'', 1914c, pp. 250-251, pi. xiii, figs. -47-17«. 



Numerous specimens from Ternate and Batjan (Labuan), five from Halmaheira 

 (Dodinga) and Great Banda, one from Morty Island near Halmaheira, one from the Kei 

 Islands, and one said to be from Australia. Also one from New Guinea (Dorey) and four 

 from Bum (Wakollo in the central part of the island, and Hat on the east coast) all of much 

 larger size. Length, excluding the Dorey and Bum specimens, 23-5-26-5 mm. ; length of 

 Dorey specimens 29-0 mm. ; length of Bum specimens 31-0-32-5 mm. 



The antennae and mentum resemble those of G. schellongi. The left mandible is 

 distinctly longer than the right, and its anterior lower tooth is more or less obsolete. The 

 lateral areas of the metasternum are punctured and more or less hairy. The difference 

 between the distinctness of the punctures in the dorsal and lateral grooves of the elytra is 

 less great than in G. schellongi. 



Gonatas tenimbrensis, n. sp. 

 Fig. XVI, 2. 



Five specimens from Tenimber (or Timor Laut), four being from Jandema. Length 

 25-5-27-0. 



Closely allied to the preceding species, from which it differs only in having still less 

 or no trace of the left anterior lower tooth, in having antennae with shorter lamellae like those 

 of G. minimus and G. cetioides, and in having the lateral areas of the metasternum 

 unpunctured and hairless. The scars on the mentum are deeply impressed throughout.
