118 Mr. G. T. Baker’s descriptions of some 
wings); also by the antenne being bluntly terminated, 
with the pectinations decidedly shorter. 
Zygena Oberthiri, n. 8. 
Corpus nigrum, thorax niger, collum albidum. Caput antenne- 
que violaceo-nigre. Ale antice nigrescentes, maculis quatuor 
anterioribus confluentibus minio-rubris, margine flavo-albido ; 
macula quinta posteriore reniformi rubra, margine flavo-albido, 
ciliis cinereo-fuscis. Ale postice minio-rubre margine nigro; ciliis 
fuscis. Femora nigra, tibie tarsique, cinereo-fusci. 
The anterior wings are of a blackish colour, with a faint bronze 
lustre. All the spots, except the posterior one, are confluent and 
of a vermilion hue, narrowly edged posteriorly and interiorly with 
cream-colour; in one specimen this cream border encircles the far 
red spot by the costa; the posterior vermilion spot, also encircled 
with cream, is kidney-shaped, placed close to the hind margin, 
with its long axis parallel thereto; the dark ground colour extends 
along the inner margin narrowly in the female, but wider in the 
male. The costa of male is edged by a narrow black line, whereas 
that of the female is edged by an extremely fine line of a creamish 
hue. The fringes are of a brownish cream-colour. The hind wings 
are vermilion, bordered with black rather broadly at the apex, but 
narrower towards the anal angle. Fringes brownish. The head 
and abdomen are bluish black; the thorax is also bluish black, 
with a whitish collar in both sexes. The femora are black, but 
the tibie and tarsi are greyish. Length, 23 to 24 mm. 
Two specimens of this very pretty Zygena were taken at 
Sebdou, both of which are in my collection. At present 
the species will stand in a somewhat isolated position, 
as, owing to the confluence of the spots, at least three- 
quarters of the fore wings are of a vermilion-colour, this 
feature separating it from any Palearctic Zygena. 
I dedicate this fine insect to Mons. C. Oberthiir, who 
has added so much to our knowledge of the Algerian 
fauna.
