S. dimensa Walk. Considerably larger (29 or 30 mm), rather longer-winged, costal vein of hindmng 
anastomosing only to abont the middle of the cell. The faint postmedian line is not, as in celhilata, parallel 
with the termen throughont but is lunnlate inward at the fold. Cape. 
S. oedocnemis Prout (5 c). Similar to cellulafa, but with the costal vein of the hindwing more as in 
dimensa, the fringes nearly as white as in invenusta. The face is of a very indefinite colour, dull red partly 
overlaid with green scales. Lines rather better developed than in most Syndromodes. The cJ is structurally 
distinct from all the others in having the hindtibia swollen almost as in Hemidromodes. S. Rhodesia. 
50. Genus: Meiuidromocles Prout. 
Palpus in shortish, in $ moderate. Tongue wanting. Antenna short and stout, vdth moderate pectinations 
in the ^ and very short and slender ones in the $. Hindtibia of the strongly swollen, with the proximal spurs 
well developed, the terminal ones very short; in the $ wth the proximal spurs short, sometimes wanting. 
Abdomen of $ robust. Venation nearly as in Syndromodes, the costal vein of the hindwing anastomosing to 
scarcely one-half the cell-length. Two closely related species, both from the semi-desert countries which 
separate the Aethiopian from the Palaearctic Region. I have described a third from India. 
H. robusta Prout (4 e). Plain green, with only the faintest possible siiggestion of paler lines. Face 
light orange-reddish. Egyptian and French Siulan and British Somaliland; the type from Port Sudan. 
H. affinis Rothsch. (4 e) only differs in having rather broad and conspicuous pale lines and is perhaps 
a race. Sahara: Hoggar Mountains. Also from Aswan, Egypt. 
51. Genus : Hieroelitliouia Prout. 
Differs from Hetnidromodes in that both sexes have only a single pair of spurs on the hindtibia. See 
further Vol. 4, p. 27. In addition to the three I'alaearctic species there described, I have provisionally referred 
to the genus one African one, of which the d' is unfortunately still unknown, and now add a second. 
H. featheri Prout (5 c). Broader and rather larger than the species of the preceding genus. Face 
green. Somaliland. 
H. migrata sp. n. (4 e). d, 23 mm. Face and palpus deep red. Vertex and antennal shaft white. 
Thorax and abdomen green, jDaler beneath. Rather more robust than typical Plierochthonia, ajjex of forewing 
rather less sharp. Green, with fine whitish irroration recalling Prasinocyma, unmarked excepting very faint 
indications of darker cell-dots. Underside rather paler.'iVoi, Kenya, 600 m, 2—8 March 1912 (Ch. Alluaud 
and R. Jeannel), type in Mus. Paris. Also from Kibwezi, Kenya and from Neu-Moschi, Kilimandjaro, 800 m. 
52. Genus: Xaiitliocliira Btlr. 
Eye rather small. Palpus of d' shortish, with minute terminal joint. Tongue present. Antenna of d 
moderately pectinated. Hindlegs lost in the unique type. Abdomen short, without crests. Forewing with 
all the subcostals stalked, the 1st anastomosing with the costal, 2nd radial from very near 1st, 1st median not 
stalked. Hindwing with distal margin weakly sinuate between the radials, abdominal margin long; costal 
anastomosing at a point with subcostal, 2nd subcostal very shortly stalked with 1st radial, 2nd radial from 
close to 1st, 1st median connate with 1st radial. Affinities quite uncertain. 
X. truddata Btlr. (2 k). Bright orange; fore wing with black-brown apical patch, in its posterior part 
with some red shading proximaUy; hindwing with a much less extended apical patch, predominantly red above, 
black-brown beneath. Madagascar. 
X. ( ’) hypocrypta Prout (5 c) can scarcely be congeneric with the preceding, but its position is equally 
doubtful. Considerably smaller, more slenderly built, different izi shape and maculation and Avith the 1st sub¬ 
costal of the forewing arising from the cell, anastomosing Avith the 2nd, as Avell as Avith the costal. ForeAving 
beneath Avith a dull purple apical patch, at costa 4 mm wide. Madagascar. 
53. Genus: Cacochloris Prout. 
From here on to the end of the Heniitheinae, all the genera are without frenulum in either sex. Gacochloris 
was erected for two sand-coloured species of rather robust build, Avith short tongue, strongly pectinated
