MICROTTA (new genus). 



Species of small size. Wings elong.ated, margins perfectly entire 

 and rounded ; apex of fore-wing obtuse ; abdominal margin of hind- 

 wing not forming a gutter to receive the abdomen, wliich latter extends 

 beyond the extremity of the wings. Fore-wing costal nervure ter- 

 minating on the costa a little beyond the middle of the wing; sub-costal 

 nervure emitting its first branch a long way before, its second a still 

 longer way after, the end of the cell; second, third, and fourth branches 

 emitted at nearly equal distances from each other; upper radial nervure 

 joining the sub-costal immediately after the end of the cell, the upper 

 discoeellular nervule is consequently wanting; the middle disco- 

 cellular is moderately short and angular in the middle, the lower 

 discoeellular extends obliquely outwards and joins the median (which 

 forms an angle to receive it) a considerable distance beyond its terminal 

 fork : the lower discoeellular is tubular only towards the median, 

 becoming atrophied towards its junctio^i with the middle discoeellular. 

 Hind-wing sub-costal nervure widely distant from the costal, upper 

 discoeellular short and oblique, middle discoeellular also short, cur- 

 ving and continuous with the lower radial ; lower discoeellular quite 

 obliterated. Head moderately broad, eyes naked ; palpi clothed in 

 front wifii long hair-scales. Antennae stout, not pale ringed; club 

 abrupt, thick, obtuse, slightly curved. Thorax weak and small. T/egs 

 strongly spined beneath ; front legs of the female with terminal rudi- 

 mentary joints rather elongated, and their spines wide apart. Colours 

 simple, entirely destitute of wavy lines above and beneath, and of 

 sub-marginal spots, lunules, or lines. 



39. — MICROTIA ELYA. 



(^ $ . Expana. 1" 3'" "Wings elongate, narrow, obtuse, and 

 entire. Dark blackish brown ; fore-wing with an oblique sub-apical 

 belt curved a little outwards, and a large sub-triangular spot in the 

 middle of the hind border orange-tawny. Hind-wing with a broad 

 discal orange-tawny stripe across the disc (a little nearer the base), and 

 widest on the abdominal border. Beneath : the same, but a little 

 paler : outer end of the sub-apical belt of fore-wing, and the whole 

 of the discal stripe of the hind-wing (except near the abdominal edge) , 

 pallid. Base of palpi and of costa of fore-wing orange-tawny. Body 

 and antennae black.
