Species of Ithopaloccra from Sierra Leone. 22.T 



me many very interesting species, among otliers that most 

 interesting and rare Argi^rocheila undifera, Stgr., wliicli, 

 owing to the keenness of observation and enthusiasm of 

 Mrs. Cator (who spent a couple of months with lier husband), 

 they were able to take in some numbers. Mr. Cator reports 

 it as one of the most sliy species he knows ; it is not a 

 strong flier, as we might imagine, but at the very least 

 alarm it drops instantly, and it is almost impossible to find 

 it in the undergrowth, so that, with its uncertain flight, it is 

 by no means easy of capture. There are several new species 

 in the collection which I here describe; my measurement for 

 the expanse of wings is taken by doubling the distance from 

 the centre of the thorax to the apex of the wing. The types 

 are in Mr. Uator's collection. 



Acrcea Calori, sp. n. 



^ . Primaries diaphanous, with the apical area blackish 

 grey for two fifths between the apex and the end of the cell ; 

 termen broadly dusky, slightly tapering to the tornus ; a 

 broad, dusky, diagonal band from the costal margin of the 

 cell across the angle of vein 2 to near the tornus ; a twin 

 dusky spot at the end of the cell, followed by a large twin 

 sj)0t ju.st beyond it ; the space between veins 3 and 4 dusky ; 

 costa slightly dusky to the cell. Secondaries dull straw- 

 colour, with a very broad dark termen, with the veins and a 

 central stripe in the vein-spaces darker and extending well 

 beyond the dark terminal area, several small black spots at 

 the base. Under surface: primaries with all the pattern 

 showing through, but the apical area and termen tinged with 

 ochreous; the veiiis and a slight central dash in the vein- 

 spaces dusky. Secondaries brownish ochreous, with two 

 black spots at the base over the cell, two spots near the base 

 in the cell, and two smaller spots on the discocellulars ; two 

 spots just outside below the cell at the base, followed by 

 two below them ; an oblique row of three spots, the uppt.-r 

 one in the angle of vein 2. All the veins are dusky fur 

 nearly their whole lengthy and there is a long, central, dusky 

 stripe between each. 



? . Like tlie male, both above and below, but larger and 

 the secondaries are rather paler. 



Expanse, ^ 72-73, ? 83 mm. 



'ihis species will come between A. epidica, Obth., and 

 vesperalisy Smith. 



Eujflcra Dorothea^ sp. n. 

 fj . Head, thorax, and abdomen extremely dark olivc-grcen.
