 clothed with gieyish jiubescence. 



//ft6. Nias l! (coll. I. W. Thomas). 



Very similar in coloration to several South American species, but differing fi-om 

 its Eastern congeners in the black clypeus and labrum, colour of the antennae, etc., 

 and eompariitively small size; L. honorata Baly has the head constricted behind and 

 a longer thorax. 



Lema imitans sp. nov. 



Lower part of face, the auteuiiae, breast, and legs black ; head, thorax, and 

 alxlomen rufous, elytra metallic blue, deei)ly punctate-striate anteriorly, the interstices 

 costate at the apex. 



Length 2 lines. 



This species, although closely allied to L. nigrilaln'is, differs in the following 

 way from that species : — The basal joints of the antennae are black, as well as the 

 following three joints (the rest are wanting), the anterior angles of the thorax are 

 slightly t.uberculiform, and the surface is entirely impunctate ; the scutellum is 

 distinctly truncate at its apex, the elytra are more strongly punctured anteriorly, but 

 the punctuation gets finer towards the apex ; lastly, the abdomen is rufous. 



Hab. Mias I. A single specimen (coll. I. W. Thomas). 



Lema celebensis sp. nov. 



Fulvous, the apex of the tibiae, and the tarsi black, thorax longer than broad, 

 imj)unctate ; elytra violaceous blue, finely punctate-striate, abdomen clothed with 

 yellow pubescence. 



Length 4 lines. 



Head deeply con.stricted behind the eyes, the latter deeply notched, antennae 

 robust, short, fulvous, the third and fourth joints alike (the two apical ones broken off) ; 

 thorax subcylindrical, longer than broad, moderately constricted at the .sides, the basal 

 sulcus deep, the sm^'ace entirely impunctate ; scutellum obscure fulvous ; elytra with 

 a distinct depression below the base, the latter distinctly, the rest of the surface very 

 finely punctate-striate, the punctures distinct to the apex and closely placed in striae, 

 the interstices imi)unctate and slightly costate at the apex ; underside and legs 

 fulvous, rather sparingly clothed with golden yellow pubescence, the apex of the tibiae, 

 and the tarsi black ; posterior femora extending to the first two abdominal segments. 



Hab. Celebes. A single specimen. 



To be separated from any of its nearly similarly coloured allies by the elongate 

 thorax, and by the colour of the tibiae and tarsi. 



Crioceris thoracica sp. nov. 



Broad, robust, black, thorax with a double row of punctures, subquadrate, elytra 

 fulvous, punctured near the suture and at the base only, underside clothed with greyish 

 pubescence. 



Length 3i to 4 lines. 



Head deeply constricted behind the eyes, the space surrounding the latter 

 rugose, labrum fulvous, antennae not extending to the middle of the elytra, black, 

 the lower three joints shining, the others pubescent, longer than broad ; fourth joint 

 nearly twice as long as the third, thorax nearly subquadrate, the sides but slightly 

 constricted at the middle, the surface without sulcus, shining, black, the middle near
