 (Wallace). Length 1 7-5-3::-7 mm. 



The puncturing of the abdominal .sterna is very variable and proves, as in L. hicolor, 

 to be of no use for the distinction of definite varieties — hence the name glabriventis becomes 

 a synonym. The central area of the metasternum bears at most a pair of symmetrically 

 placed punctures. It never bears irregular punctures such as are ordinarily characteristic 

 t)f L. ci/cJotaenitis. 



Leptaulax timoriensis (Percheron). 



Passalus (i»>oriensis, Percheron, 1841, pp. lit-il. pi. l.\xviii. fi^. 1. 

 Leptaulax timoriensis, Zang, 1905c, p. 223. 



Three specimens from Gng. Leo, Dutch Timor, 2,000-4,000 ft. ; five from Dilli. Port 

 Timor, 2.500 ft. ; one from Ihvaki. Wetter ; and two from the Alor Islands. Length 24-35 

 mm. 



This species is very near L. dentatus, being distinguished only by the structure of the 

 pronotum, which is less distinctly rectangular, and is unpunctured in the anterior angles, 

 except in very small specimens in which one or two punctures may be present in this 

 position. In small specimens the puncturing in and around the pronotal scars and marginal 

 grooves is more extensive than in large ones. 



Leptaulax anna, Zang. 



LeplaiihiT nvna. Zaiif:. lOO.'ir;. p. ,3H>. 



Four specimens from B. Aru Hassa, Sambawa, 2,000-5.000 ft. Length 30-31 mm. 



L. anna i.s very like L. timoriensis, but has the pronotal .scars less densely punctured, 

 has the elytra more distinctly broadened behind with their lateral grooves matt and 

 marked with somewhat worn-looking punctures, and has the metasternum hairy laterally 

 and in front. In the Van de Poll specimens (30-31 mm. long) the lateral and intermediate 

 areas of the metasternum are united ; but in a smaller .specimen in our collection (26 mm. 

 long and a co-type) they are di.stinct, though the ridge between them is somewhat weak 

 behind. The elytra are separate.
