Macroglossa lepcha, n. sp. 



Allied to M. obscuriceps, from which it differs in having the head and thorax olive- 

 green ; the black band across the abdomen feebly developed ; the primaries narrower ; 

 the central greyish band (which is scarcely distinguishable in M. ohscurkeps) quite 

 obsolete, the subbasal lines bounding it internally, converted into a black band, which 

 is broad on the inner margin, and tapers towards the costa ; wings below with the trans- 

 verse lines less distinctly marked ; the internal orange area brighter. Expanse of wings 

 2 inches. 



Calcutta (Atkinson). Coll. Dr. O. Staudinger. 



This species is also allied (but less closely) to M. avicula and M. lombylans. Mr F. 

 Moore has generously permitted me to describe the Sphingidae recently forwarded to 

 him by Dr. Staudinger, and forming part of the late Mr. Atkinson's collection.
