iSz Records of the Indian Museum. [Vol. XVI, 



This very striking new species seems at present to stand rather 

 remote from its congeners. 



It differs from the members of the lacteola group in the 

 characters of the and appendages, the upper pair being without a 

 ventral spur so far as I can determine, whilst it resembles them in 

 having a non-metallic upper lip. 



For the present it may well be allowed to stand as the sole 

 representative of a distinct group within the genus. 



Types a* 9 oi A. pier is and of A. splendidissima, n. spp., 

 will be returned to the Indian Museum. 



Lastly one may remark that whilst A. pygmaea (Ramb.) is 

 well represented in the Museum collection by specimens from 

 Northern and Peninsular India, A. incisa, Selys, is not included 

 from any locality west of Assam ; the collection has in addition to a 

 specimen taken on the Abor Expedition, one from Rangoon and 

 one from the Inle Lake, S. Shan States (7215/H.1). All three 

 are males. For synonymy of A. Pygmaea see Ris' paper referred 

 to in the Supplementa Entomologica ^ No. V. 



Genus Argiocnemis. 



See Ris, Abhand. Seiickenb. Natiirf. GeseUsch., Bd. XXXIV, p. 517 

 (19.13)- 



The upper anal appendages of the male, at least in the case 

 of Argiocnemis ruhescens, Selys, bears a very strong resemblance to 

 that of A. lacteola, Selys, and its immediate allies, as do the 

 appendages of the form I have called A. obscura from Upper 

 Assam. The spur is not visible without a partial removal of the 

 appendages. I have not been able to re-examine the type of 

 A. aborense, Mihi, to determine w^hether the spur is present in it 

 also. 



Ris {loc. cit.) has come to the conclusion, suggested by Selys, 

 that the following names are all synonyms of A. nibescens, Selys, 

 A. rubiola, Selys and var. interuiedea, Selys, race sumatraita ,'Kru.geY , 

 A. lunulata, Selys, A. nigricans, Selys. 



The position of A. obscura, Laidlaw {Rec. Ind. Mus., VIII, 

 p. 346, 1914) is uncertain. A. aborcnse, Laidlaw (loc. cit., p. 347) is 

 certainly distinct. 



I have not seen any specimens belonging to the genus from 

 Peninsular India, and have not enough material to determine 

 satisfactorily the status of specimens that I have for examination. 

 But I am inclined to believe that one or more of these specimens 

 from the Malay Peninsula are specifically distinct from A. rubes- 

 cens, Selys. 



A minor character which I have noticed in all specimens 

 of Argiocnemis that I have examined is perhaps worth note. It is 

 that the dorsum of the thorax is almost entirely devoid of the 

 hairs which are so numerous in some genera.
