NEOLYBiEBA KEMOTA, Blackb. 



Among the allies of Mtlatiteriua this species is readily 

 identifiable by the fifth interstice on each elytron being sup- 

 plied with a distinct preajDical callus. Many of the scales on 

 the upper-surface have, in some lights, a beautiful golden 

 lustre, a fact not m.entioned in the original description, but 

 of extremely rare occurrence in the Criiytorliyvclilden. 



AoNYCHUs STiiiATUs, Lea, var. 



Two specimens from the Northern Territory evidently 

 represent a variety of this species. They differ from the types 

 in having the darker scales absent from the prothorax, except 

 for a feeble spot on each side of the base ; on the elytra also 

 they occupy considerably less space than the whitish ones, and 

 form somewhat angular markings abont the suture and sides. 



Mechistocerus maemoreus, n. sp. 



d" . Black, antennae and tarsi red. Densely clothed with 

 scales closely applied to derm ; and with stouter suberect ones. 



Head with dense and rather coarse punctures. Ocular 

 fovea elongate, rather suddenly enlarged in front. Rostrum 

 long and thin ; basal third with coarse partially-concealed 

 punctures, leaving three feeble ridges, elsewhere shining, and 

 with small, clearly-defined punctures. Antennae thin; scape 

 inserted one-third from apex of rostrum, first joint of funicle 

 stouter, but no longer than second. Froiliovd-v lightly trans- 

 verse, sides strongly rounded ; with a feeble median carina : 

 with large and usually distinct punctures. Elytra elongate- 

 subcordate, about one-third wider than prothorax : with rows 

 of large, but more or less concealed punctures. Mefasternuni 

 distinctly shorter than the following segment: with fairly 

 numerous punctures, including a distinct row on each epis- 

 ternum ; narrowly impressed along middle, but the impression 

 deep and dilated at both ends. Ahdomen with sparse punc- 

 tures, some as large as on metasternum, but most of them 

 smaller ; basal segment feebly depressed in middle. Femora 

 lightly dentate, the hind ones jnst passing apex of elytra. 

 Length, 5j-7^ mm. 



9 . Differs in having the rostrum thinner in front of 

 antennae, much less of the base with coarse punctures, and 

 without median ridges ; antennae inserted not so close to apex 

 of rostrum; and basal segment of abdomen gently convex.
