length in the two sexes ; fifth ventral segment transversely depressed 

 in the middle at apex in $. 



Var. ? The elytral fasciae wanting. 



Hob. Philippine Is., Luzon [type], Pulo Batu (Semper, 

 in Mus. Brit.). 



Amongst the ten examples of this species in the Museum 

 (eight of which were obtained by Semper), there are three 

 males, also a pair from Luzon ; the immaculate specimen 

 ($), also from Luzon, has slightly longer elytra, the head 

 more rounded behind, and the occipital groove a little 

 deeper than in the rest. M. bicincta is a rather large, 

 robust form, with interruptedly albo- or flavo-bifasciate, 

 closely punctate, feebly striate elytra; a somewhat oval 

 head, with a short, shallow occipital groove behind; large 

 eyes; slender antennae, with joints 9-11 thickened and 

 1 1 greatly elongated in <$ ; a long, roughly sculptured pro- 

 thorax; stout legs, and a broad basal joint to the anterior 

 tarsi. The males are narrower than the females and have 

 the pygidium subtruncate at the tip ; the femora and tibiae 

 vary in colour, as in several of the allied species. M. 

 pubescens, Pic, from Balabac Island, near Borneo, would 

 appear to have a still longer terminal joint to the antennae 



8. Macratria leucozona, n. sp. (Plate LXIV, fig. 16, <$.) 



Moderately elongate, narrow, shining (when denuded); closely, 

 finely pubescent, the vestiture in great part fuscous, except along 

 the basal margin of the prothorax, on a common, broad, dense 

 post-basal fascia on the elytra, and on the greater part of the under 

 surface, where it is white or cinereous ; black, the antennae, mouth- 

 parts, palpi, tarsi (joint 1 of the posterior pair excepted), and anterior 

 tibiae (except at the base), testaceous. Head rather small, convex, 

 obconic, very minutely, diffusely punctate, the occipital groove 

 short, deep, the eyes comparatively small, distant from the base; 

 maxillary palpi long, stout, the terminal joint large, cultriform; 

 antennae slender, joints 9-11 thickened, 9 and 10 each a little 

 longer than 8, 11 in $ about as long as the two preceding united. 

 Prothorax convex, narrow, elongate -oval, attenuate in front, densely, 

 roughly punctate, the basal groove hidden by the fringe of white 

 hairs. Elytra moderately long, much wider than the head, gradually 

 narrowing from the base, closely, somewhat roughly punctate, and 

 also feebly punctato-striate on the anterior half of the disc, the 

 seriate punctures scarcely coarser than the others, the interstices
