J anuary. 
Ohs. — Mr. Masters tells me that he found this species in- 
habiting caves in thousands in both the above-mentioned widely 
separate localities ; the caves at Lawson are very damp, and so 
overshadowed by precipitous I’ocks, that on the hottest days in 
January the place is perfectly cool and gloomy, while those at 
Bowral are situated in a small dry gully altogether exposed to 
the sun ; at the first locality another fly, Br achy dicrania fumosa, 
described by me in the present paper, occurs in large numbers, 
and at first glance appears greatly to resemble the above.
