abnormally early, only just after R 1 , which is almost connate with sub- 
costals, hindwing with SC 2 scarcely stalked, hindtibia without median 
spur. The costal edge of the forewing is less strongly purple, and the 
terminal adornment is slightly different. If this be a Heterocrita, the 
tibial armature of the genus must be variable, which I already suspect. 
But I have only seen two or three examples, and some of them may have 
been broken. That is clearly not the case, however, with the present 
specimen. Walker says of his discerpta that it has four long spurs. At 
present his type A has a single median and a pair of terminal, his $ a single 
median only. 
Allochrostes biornata, n. sp. (PI. XII, Fig. 38). 
A, 14 mm. Face green. Palpus greenish. Vertex with some red 
scales posteriorly and crossed by a red line behind the antennae. Antennal 
shaft white with some red dots. Thorax green, anteriorly dark red spotted 
with white ; abdomen dorsally red dusted with white, and with white 
dorsal spots, the third large. 
Forewing yellow green (somewhat faded), the costal margin red,, 
irregularly dappled and irrorated with white, a larger white spot in apex, 
termen narrowly red, containing very large white spots at veins ; ante- 
median and postmedian lines waved, whitish, very weak ; discal spot 
elongate, somewhat curved, white, surrounded with red ; fringe long,, 
white, proximal half marked with red at vein-ends. Hindwing without 
red costa, but with a thick, interrupted sub-basal red line, conspicuous- 
in cell and at inner margin ; the rest nearly as in forewing, the cell-spot 
slightly less elongate, more reniform, antemedian line not discernible. 
Underside of forewing more broadly red costally, cell-spot red, not white- 
centred ; both wings with a thick red terminal line. 
Waterberg District, January to March, 1899. Type in Transvaal 
Museum. 
Ckrysocraspedct leighata Warr., ab. dehonorata, n. ab. (PI. — , Fig. 13). 
Differs from typical leighata (Warr. Novit. Zool., xi, 466 ; collected 
at the same locality and date) in the entire absence of the dark purple 
sub terminal bands both above and below, the yellow at termen thus appear- 
ing less sharply defined. 
Durban, 26th February, 1909. Type § in coll. L. B. Prout. 
It is not absolutely impossible that C. nigribasalis Warr. (Novit. Zool.> 
xvi, 112) is also an aberration of this variable species, 
Anacosymbia , n. gen. 
Face smooth. Palpus rather short, with appressed scales. Tongue 
developed. Antenna in A bipectinate with long, slender, finely, ciliated 
branches, apical segments merely shortly ciliated ; in 2 very minutely 
ciliated. Femora glabrous ; hindtibia in A without spurs, tarsus not 
aborted, almost as long as tibia ; $ with all spurs. Wings shaped as in 
Epicosymbia. Forewing with cell about one-half, DC normal, SC 2 from 
cell, anastomosing with SC 1 and with SC 3 ' 4 to form a double areole, SC 5 
arising before the latter anastomosis, R 2 normal, M 1 well separate. Hind- 
wing with venation normal, SC 2 extremely short-stalked with R 1 .
