AULACOPHORA MARGINATA. 41 



it is distinguished from species otherwise similarly coloured 

 (with black elytra). 



Aulacophora paliiata , Schall. 

 » orientalis , Hornst. 



I cannot distinguish the two above species , as the des- 

 criptions are similar. The species from Sumatra, described 

 by Hornstedt , is most probably identical with those in the 

 present collection , although the insect may also have its 

 habitat in India, from which locality Schaller's specimens 

 were described. 



Aulacopliora coffeoe, Hornst. 



I refer the specimens obtained at Sumatra to this spe- 

 cies. Many closely allied forms exist " in the Malayan Ar- 

 chipelago and otherwhere. 



All the specimens of the present species before me , have 

 the vertex of the head piceous, the entire underside and 

 four posterior legs black (Hornstedt says green which is 

 no doubt a mistake as no such coloured species exists). The 

 elytra are opaque and very finely punctured. The transverse 

 thoracic groove is deep and extends to the sides. 



Malarosoma parvula , n. sp. 



Elongate, subparallel, testaceous, terminal jonts of the 

 antennae black. Thorax very minutely , elytra finely and 

 closely punctured. — Length 2 lines. 



Head impunctate , deeply transversely grooved between 

 the eyes , encarpae contiguous , clypeus triangular , apex 

 of jaws black. Antennae rather robust, extending to one 

 third the length of the elytra , the third joint one half 

 longer than the second, four lower joints obscure fulvous , 

 the rest black. Thorax one half broader than long, the 

 sides strongly rounded and finely margined, the angles
