particularly narrow but much the same width throughout; the first joint of the antennae is 

 very much incrassate, the third joint Tabanits like, and the forehead is narrow.

Pangoninae. 



The gênera in this division recorded from New Guinea and neighbouring islands are 

 as yet poor in the number of species and include only : 

 Pangonia (in sensu latu), Chrysops and Silvms.

Only two species hâve been described as yet. One new species is added. 



Pangonia lasiophthalma Macq. Suites à Buffon, I, p. 193 (1834), perhaps the same as Erephopsis 

 contigua Walker, from Australia, Diatomineura caliginosa Walker, Proc. Linn. Soc. London, VIII, 

 p. 108 (1865); Ricardo, Ann. Mag. Nat. Hist. (7) V, p. 118 (1900).

1. Diatomineura caliginosa Walker.
