I think I took at least one other specimen, but gave it 
away very soon. The same species has occurred to me at 
Cairo, but only 2. The Z, if I mistake not, is still 
unknown.

PALARUS LEPIDUS, KI]. 
The synonymy of the smaller Palarus spp. is much 
confused, and Mr. Saunders appears to have had some 
doubt what to call these specimens. 
They agree entirely with Egyptian insects in my collec- 
tion which were determined for me by Herr Kohl as 
lepidus. I did not find this species in Algeria myself; 
probably I left before it had appeared.

PALARUS SP. ? (aetus, K1., sec. E. Saunders) 
Mr. Saunders considered this to be a 2 of laetus, K1., of 
which, according to Herr Kohl i. litt., Aistrio, Spin., is a 
synonym. As I only know f f of laetws (taken by myself in 
Egypt and determined by Kohl), I cannot say for certain 
that this is not its 2; but I am more inclined to think 
that it belongs to the species next to be recorded whose f 
was taken in the same locality (Biskra), and in general 
appearance agrees extremely well with it. (I believe that 
laetus is only recorded from Egypt, though it is quite 
likely that it may occur algo in Algeria.) But it must be 
admitted that the present insect agrees perfectly with
