with a large triang-ular depression on each side. El\tra strongly narrowed 

 from behind the shoulders to a little bevnnd the middle, thence subparallel to 

 apex ; scutellar area broadly depressed. Pygidimn short, obtusely rounded. 

 Anterior tarsi strongly expanded, 1st joint twice as wide as long, 2nd and 3rd 

 larger, 4th very short and wide, oth almost as broad as long. 



Maxillary palpi highly modified, 2nd joint long, flat, expanded towards 

 apex, closely united to the short broad 3rd joint; 4th joint lying against the 

 2nd and 3rd, combined with a long, rather clavate arm and three lung hairy 

 finger-like processes arising from its base (fig. 3). 



Length 4 mm. 



Hah. BoRXEO, Sandakan (C F. Bake/'). 



A single specimen, but veiy distinct, apart from the peculiar tarsi 

 and palpi of the S , in the bi-impressed base of the thorax and the 

 strongly narrowed elytra. 



Calycella nigriceps, sjd. n. 



2 . J'ulvous, with the head, except labrum, tops of elvtra and tarsi of first 

 two pairs of legs black; the antennae, except the two basal joints, and the 

 anterior and intermediate tibiae are also fuscous. Antennae serrate, joints 

 3-10 triangular, 3rd as long as 4th and oth together. Last joint of maxillary 

 palpi somewhat spoon-shaped, the inner side and superior face yery short, so 

 that the apex, which is to some extent excavate, is very oblique and expcsed 

 to view from above. Pygidium short, triangular, but little longer than hypo- 

 pvgium. Third and fourth joints of first two pairs of legs expanded, the latter 

 divided almost to the base. The whole surface finely, but, except on the elytra, 

 not densely pnnctate and pubescent, the pubescence of the same colour as the 

 derm, except that of the tibiae which is golden. 



Length 10 mm. 



Hal. Malay Pexixsula, Negri Sembilan (S". JV. Bidley). 



Yer\' distinct on account of its size and colom-, as well as the greater 

 conyexity, both longitudinally and transversely, of its dorsal surface, 

 which give it more the appearance of a Calyce. The posterior angles of 

 the head are acute, and project laterally to considerably beyond the eves. 



Calycella horneensis, sp. n. 



Rufous-brown, clothed with a golden pubescence. Eyes large, separated 

 by a space less than the width of one of them, more nearly approaching the 

 back of the head than iu the other species of the genus, but separated from it 

 by a narrow strip which projects laterally behind the eye. Anterior and 

 posterior angles of the thorax completely rounded. Elytra convex, not 

 depressed along the suture. Pygidium short, triangular, scarcely longer than
