MACELLOPALri'S. 123 



stripe. Legs missing, except the coxse, and the femur and tibia of 

 one hind leg; all these are uniformly light brown, the femur 

 having a very narrow black ring at the base. Wings pale yellow, 

 costal border darker yellowish brown ; stigma brown, distinct ; 

 halteres light brown, with a black spot on upper side of knob. 



Length, JO mm. 



Described from one specimen in the Indian Museum from 

 Sibsagar. 



Bigot's description of his flaveolus is very short, and would 

 apply to the present species, but as he marked fulvidus himself as 

 a new species I presume it to be distinct. 



Some considerations on the possible synonymy of this genus 

 with Leptipaljous, Roud., and Heliomyia, Dol., have been set forth 

 by me.* Of the three genera, Lejjtipaljms (1850) would take 

 precedence. Apart from the two species described by me, only 

 one other is known, flaveolus, Big., from New Guinea.
