154 Mr. R. McLachlan on 
extending to Turkestan ; always apparently very rare, but 
no doubt owing to want of systematic searching. 
Creagris plumbeus, Oliv. 
Hab. Algiers, on the ramparts, 3rd May, 1893; Sidi- 
Ferrouch, on the coast west of Algiers, 8th May, 1898 ; 
Azazga, at light in the inn, 13th September, 1893 ; various 
localities about Biskra in May and June, 1894; 13 examples 
in all. 
Those from Algiers and neighbourhood equal the largest 
South European examples, those from Biskra are distinctly 
smaller. The markings on the pronotum vary. In all 
(excepting one ¢ from Biskra) the dark interruptions on 
the neuration are absent or scarcely visible, but examples 
from Sicily are similar in this respect. I possess the species 
also from Tiout and Méchéria in the province of Oran 
(L. Bleuse). 
Hagen has pointed out (Stett. ent. Zeit., xxvii, p. 289) 
that the probable range of this insect is very great, if 
certain forms presenting slight differences are considered 
as scarcely worthy of separate names. The same form 
(slightly modified) would thus extend over all the Mediter- 
ranean region, the whole of Africa to the Cape of Good 
Hope, Asia Minor and Central Asia, and probably to India 
and Ceylon if C. perfidus, sedulus and adversus, Walk. 
(scarcely separable znter se) be considered. 
C. murinus, Klug (a synonym of plumbeus) is given by 
Hagen (1. c.) following Schneider, as extending from Syria 
to the Cape of Good Hope, and further on (p. 402) as from 
the Cape only. Klug, Symb. Phys. gives Syria as the 
locality, and on pl. xxxvi, fig. 5 it is indicated as syriacus, 
a name that does not occur in the text. 
Myrmeleon lugdunensis, Villers, has been identified with 
C. plumbeus. Could this be sustained that name would 
have priority ; the very short description does not convey 
to my mind any indication that Villers had this insect 
before him. 
Myrmecelurus atrox, Walk. 
Hab. Biskra, 3rd June, 1894, 3 ¢, 2 2. Practically 
agreeing with Walker’s type from Turkey; the Indian 
M. acerbus, Walk., is perhaps not different. Differing 
from typical M. trigrammus, Pallas, in its smaller size, in
