A. Hiiultibia of ^ with 3 spurs. Antenna of $ simple. 
L. rubricorpus IFarr. (= plagiata Auriv.', (J = niveicristata Front, ? aenospila B.-Bak). 
Abdomen of B partly green, the crests white; that of the 9 predominantly red. The B lacks the reddish spot 
on abdominal margin of hind wing, often also that at tornus of forewing, rubricorpus was described from Nigeria, 
plagiata from Iviliniandjaro, niveicristata, from Natal, but the species is now known to inhabit also Sierra 
Leone, Ivory Coast, Cameroons, Nyasaland, Transvaal and even Madagascar; the latter perhaps a race, with 
larger, blacker blotches, but only a single $ yet known. omorrhodia suhsp. nov. (2 f) has the white dorsal 
crests on tei’gites 2—4 of the abdomen larger than in any other ^ of rubricorpus, a rosy mark at base of costa 
of fore wing just liehind the fine white costal line, a very small one at tornus of hindwing; hindwing less angled 
than in typical rubricor pus. Sao Thome Island, January cb Eebruary 192G (T. A. Babn.s), 3 $$ in the Joicey 
collection. 
B. Hindtibia of B with 2 spurs. Antenna of $ sometimes (palliata) pectinate. 
L. atricristata sp. nov. Evidently near rubricorpus (2 f), notwithstanding the loss of the proximal 
spur of the hindtibia. Abdomen with the anterior crests black. Hindleg slender throughout. Wing-shape and 
markings nearly as in well-marked B rubricorpus. Nyasaland; Zomba, October 1925, 1 (J, expanding 37 mm; 
in the Joicey collection, sent by H. Barlow. 
L. palliata Warr. (5 a) is a rather large species, recognizable at a glance by the very large, irregu- 
^larly oval distal patch on the forewing; the markings at base and abdominal margin vary in extent. In 
^le name-type all these dark markings are reddish. — ab. ustipennis Warr. has the markings dark purple-grey. 
Both forms were described from Southern Nigeria but the species is found from Sierra Leone to the Congo 
tand on i\It. Mlanje, Nyasaland. 
14. Genus: Heterocrita Warr. 
W ARREX founded this genus on a d of bidentata B.-Bak., which he misidentified as “araria Guen.” This 
sjiecies has, as IVarrexs diagnosis indicates, thick and lamellate antenna and 2 spurs only on the hindtibia. The 
$ palpus is extremely long and slender, otherwise the sexes are alike. Both wings have the distal margin 
excavated between the 1st and the 3rd radial, the forewing scarcely noticeably, the hindwing rather deeply. In 
the “Genera Insectorum” (fasc. 139, j). 138) I misapplied the name Heterocrita to the true araria Guen. which 
differs in the antenna, the hindtibia, $ palpus, etc.; see Adicocrita. 
H, bidendata B.-Bak. is a small species, recognizable by the shape and structure, the rather large 
red-brown rings on the 3rd discocellular and the purplish costal margin and distal margins, the latter slightly 
expanding near the apex and again (triangularly) at the tornus. Sierra Leone to Angola (the type locality), 
also from Nandi. 
15. Genus:Adicocrita gen. nov. 
I propose this name for “Heterocrita ITn/r.”. Prout olim, in err. (Gen. Ins. 139, p. 138); see above. The 
$ palpus has the 3rd joint of moderate length. Antenna in A shortly pectinate, in $ simple. Hindtibia in both 
sexes with 1 proximal and 2 terminal spurs. Abdomen with small crests, about as in Lophorrhachia, to Sect. A 
of which, indeed, the present genus shows an evident relationship, though differing in the B hindtibia, the 
excavated distal margin of the hindwing and the rather wide separation of the 1st median at its origin from the 
3rd radial on both wings. Only known from South Africa. 
A, araria Guen., founded on a damaged $ from Namaqualand, is larger than koranata {'2 g) and appears 
to differ further in having the abdomen (excepting the green base) predominantly wdiite, only with 2 anterrior 
red, white-centred spots, and the fringes reddish. 
A. koranata Feld. (2 g) has the abdomen above a good deal clouded with red, the crests red, some¬ 
times in the bordered on each side with white. Cell-dots red. Postmedian red vein dots (distinct in araria 
type) may be present or obsolete. Terminal line red. Fringe partly white, spotted with red at the veins. $ with 
a red mark at middle of abdominal margin of hindwing. Cape Colony and reaching the Transvaal. Perhaps a 
form of the following. 
A. discerpta Walk. (2 b) differs chiefly in having narrow purple borders above and beneath, but in 
adchtion the ter men of the hindwing seems less strongly toothed at the 1st and 3rd ra dials. Cape of Good 
Hope.
