New and lilllc-knoivn Lagriidae and PediUdae. 203 



shallow, and arranged in regular rows, becoming fine towards the 

 apex, the narrow interspaces somewhat convex. Pygidium in $ ( ?) 

 deeply notched at the tip and subcarinate down the middle in front 

 of the emargination, that of (J ( ?) subtruncatc at the tip, simple. 

 Legs stout; basal joint of anterior tarsi much thickened in both 

 sexes. 



Length 4f-G mm. 



Hab. New Guinea, Korido, Geelvink Bay (Beccari : 

 type); Morty: Batchian; Gilolo. 



The above description is taken from six specimens in 

 the Museum, all probably collected by Wallace, including 

 a pair from Batchian, those with a truncated pygidium 

 assumed to be males. They differ from M. beccarii, accord- 

 ing to Pic's diagnosis, in having much darker legs; but 

 as these limbs frequently vary in colour in the allied 

 species, no importance need to be attached to this char- 

 acter. His variety submetalliea is said to be larger, and 

 to have a more robust, broader prothorax, and therefore 

 seems to be more nearly related to M. wallacei, from 

 Waigiou, which has joints 1-8 of the antennae much 

 stouter and almost wholly black, the prothorax rounded 

 and less attenuate in front, etc. 



2. Macratria wallacei, n. sp. (Plate LXIV, fig. 13, <$, 

 antenna.) 



Elongate, robust, shining, sparsely clothed with rather long' 

 adpressed, brownish-cinereous hairs; black, with a metallic bluish 

 lustre in certain lights, the legs nigro-piceous, the mandibles and 

 the maxillary palpi, and the basal joints of the antennae in part, 

 testaceous. Head as long as broad, much narrower than the pro- 

 thorax considerably developed behind the comparatively small eyes, 

 rounded at the sides posteriorly, and feebly emarginate at the base, 

 closely, minutely punctate; antennae rather long, comparatively 

 stout, joints 4-8 gradually widened, slightly longer than broad, 

 9-11 elongate and much thickened, together about the length of 

 3-8 united, 9 more than twice the length of 8, 11 very little longer 

 than 10. Prothorax convex, greatly developed, oblong-oval, not 

 compressed on the flanks posteriorly, rather coarsely, closely punc- 

 tate, the basal groove sharply defined. Elytra moderately long, 

 much wider than the prothorax, narrowed from the base, separately 

 rounded at the a] lex, flattened on the disc; rather sparsely punctate, 

 the punctures on the anterior half coarse, shallow, and arrange d in 

 regular rows, becoming fine towards the apex, the narrow int.
