MICROSETIA, Stephens. 

 This genus, as the name implies, contains a group of exceedingly minute, indeed the most minute, Lepidopterous 

 insects : the palpi are rather long, slender, and somewhat divaricating and incurved ; the terminal joint more 

 slender, and shorter than the preceding ; the antennas short and simple ; the head with a slight tuft : and the 

 wings convoluted in repose ; the fore ones elongate, somewhat linear, of dark or black colours, with a pale streak 

 near the base, and another (interrupted) towards the apex of the wings ; the fringe of all the wings is 

 very deep. 



Species I. — Microsetia sub-bistrigella — (Haworth, &c. ; Wood, fig. 1343 ; and our Plate CXII., Fig. 

 30) — Expands 5^ lines ; fore wings black or blackish, with a straight linear fascia before, and another beyond 

 the middle almost interrupted, both snow-white, silvery, or pale lutescent, the latter sometimes continuous, and 

 slightly curved ; hind wings dusky black. Taken in woods at the beginning of June. 



. Species 2. — Microsetia obsoletella — (Stephens; Wood, fig. 1344, and our Plate CXII., Fig. 31) 



Expands 5^ lines ; fore wings black, with a nearly obsolete slender fascia across the middle of the wing of ashj'- 

 white, and a faint yellowish spot near the apex of the costa : hind wings dusky-black. Taken in June, at
