features, not noticed in the original description, or inaccurately 

 stated, require recording. The puncturation of the elytra, 

 though becoming very fine at the apex, is not actually "obsolete." 

 The prothorax has the lateral carina strongly developed just 

 behind the anterior angles, but quite obsolete behind the anterior 

 transverse impression; the sides are hardly incurved laterally. 

 The ventral segments 3-6 are finely punctate behind the posterior 

 coxa?. 



g. (From a specimen in the collection of the National Museum, 

 Melbourne), with apical (sixth) ventral segment more strongly 

 punctate than female, and with the usual median notch so reduced 

 as to be with difficulty perceived; in fact it may be called 

 obsolete. 



I have detected the presence of wings in M. pulchra. 



Megacephala castelnaui, n.sp. 



Green; head between eyes dark in middle with golden tints 

 on each side; prothorax with middle of disc bluish-black; elytra 

 with a golden tint on disc in some lights, apex with narrow 

 testaceous margin. Mandibles (apex black), labrum, antennae, 

 palpi, and legs testaceous (tibiae, palpi, antennae, except basal 

 joint, paler). Underside of prothorax, sides of body, and anterior 

 ventral segments green; two penultimate ventral segments brown 

 in middle, becoming lighter-coloured towards sides; apical seg- 

 ments subtestaceous. 



Prothorax with a lateral carina on anterior fourth. Elytra 

 strongly punctate, puncturation strong on basal half, becoming 

 finer posteriorly, continuing to apex; the derm smooth between 

 the punctures (though slightly undulate on lateral parts of basal 

 half of disc). Ventral segments longitudinally rugulose towards 

 sides, segments 3-6 finely punctate backwards from posterior 

 coxal cavities. Length 18, breadth 7 mm.
