metallic gloss, legs somewhat paler. Sac small, decorated with grass stalks, not differing much from those 
of allied species. On the wing at end of June. Bjarre, Lebanon. Probably only a mountain form of the 
preceding species. 
24. Family: Aegeriidae.

S. talisehensis Bril. (16 f). We are now able to give an illustration of this species that was newly de- talischcnsis. 
scribed in Vol. 2, p. 386. — Further we are in a position to give a picture of S. melliniformis Lasp. (16 i). 
7. Genus: DJpsosphecia Splr. 
We are also glad to be able to give an illustration of the species D. roseiventris Brtl. which was 
first described in Yol. 2, p. 393 (16 f). — Similarly of I), barbara Brtl. (16 h). 
8. Genus: Cliamaespliecfa Splr. 
The illustration of this Genus in Vol. 2 can now be amplified by the illustration of Ch. icteropus 
unicolor Bag. (16 i). See Vol. 2, p. 398. unicolor. 
25. Family: Cossidae. 
2. Genus: Cossus F. 
C. osthelderi Daniel. Wing contour wider, apex more truncate than in C. cossus. Body and forewings osthelderi. 
pale, abdomen sleek, collar merely as a black fringe, without yellow edge. Markings vary exceedingly, all 
striations also on hindwings, more distinct owing to the paler ground colour, central area of forewings more 
richly striated with black. 50 — 55 mm. North Amanus. 
C. tablai Dumont. Not compared by the author to any known species. Thorax black, abdomen ochreous tablai. 
brown, only the 2 first segments whitish. Forewings pale grey with black striations that are particularly 
dense at base, at inner margin and to half-way along costa. From there to apex striations are still more 
prominent as they stand out on whiter ground. Ground colour consists of irregular patches of white to 
ochreous red. The largest patches are above the inner part of vein 1, in the cell and around the base of vein 
2, where there is one patch on either side. A large white patch from vein 6 to costa, beyond same there 
are 5 more to the apex. There are black spots on costa from which the reticular lines spread, these are 
most dense over the centre of the inner margin, least dense in outer marginal area. Except for the white sub¬ 
costal nervure, all the veins are blackish. Base and anal angle whitish. Hindwings unicolourous grey, paler 
at base. $ 64 mm. Tahla (Morocco). The larva feeds in a species of Acacia.
