Described from a S in inferior condition in the British Museum 

 {type) from .the Khasi Hills {SJaden), and 3 5 ? in Indian 

 Museum : 30.vii. 1904, labelled "caught in hospital "; 31. vii. 1904, 

 " caught in Kolasil " ; the third specimen from above Tura, Garo 

 Hills, Assam, 3500-3900 ft., Sept. 1917 {tgpe $ ) {Mrs. Kemp). A 

 short, thick-set, Megaspis-Uke species, yet undoubtedly an Enstalis ; 

 closely allied to latus, Macq., from which it a])pears to be specifically 

 separated by the characters stated in the table of species. E. latus 

 may possibly be a Megaspis, as Macquart notes the scutellum as 

 broad, although in his figure it appears of normal size. He does 

 not mention the wrinkled space on the frons.
