Molophilus plagiatus is related to M. cruciferus, Alexander, 
and MM. pulcherrimus, Kdwards, but is a very distinct species. 
AMolophilus sublateralis, sp. n. 
Male.—-Length about 3 mm. ; wing 3°3 mm. 
Female.—Length about 4°5 mm. ; wing 4°4 mm. 
Generally similar to M. playiatus, sp. n., differing as 
follows :— 
Antennal scape dark brown, the flagellum very pale testa- 
ceous yellow. Head dark brown. Mesonotal prascutum 
obscure yellow medially, the anterior margin broadly dark 
brown, this area sending caudad two conspicuous, sublateral, 
brown stripes that cross the suture and suffuse the centres 
of the scutal lobes, the extreme anterior Jateral margin of 
the preescutum likewise darkened, the space between this 
and the sublateral brown stripe obscure testaceous yellow ; 
postnotum pale, a little infuscated near the root of the 
halteres. Pleura with the dark brown stripe narrower, the 
dorsal portion being much paler than the deep brown ventral 
portion, this latter passing immediately beneath the root 
of the halteres ; ventral pleurites and the sternites silvery 
white. Fore femora covered with dense black sete as in 
plagiatus ; fore tibiee and tarsi likewise dark - coloured. 
Wings grey, the costal margin broadly and conspicuously 
light yellow; small dark patches of macrotrichiz much more 
abundant aud more clearly defined than in plagiatus, these
