generic name, and this precludes its homonymy with Necro- 
philus Latreille. 
In 1857 Schaum, in the first article of the first volume of 
the “Berliner Entomologische Zeitschrift,” gave a descrip- 
tion and excellent figures of what he regarded as Roux’s 
insect, with an account of the alimentary canal and nervous 
system, drawn from some 20 specimens which he had cap- 
tured in 1852 in the dust of tombs at Beni-Hassan, near 
Cairo. Schaum was strongly of the opinion that the insect 
was a larval Nemoptera. Westwood had previously repro- 
duced Roux’s figure in the second volume of his “Introduc- 
tion to the Modern Classification of Insects,” (1840) and 
had ventured the suggestion that the insect from its size 
might either produce a Nemoptera, Bittacus or Panorpa.” 
Within more recent years Roux’s or Schaum’s figures have 
been reproduced in various other general accounts of the 
Neuroptera, such as those of Sharp, Navas and Maxwell- 
Lefroy. 
The mystery which has so long enveloped the affinities of 
Necrophylus has been recently dispelled by G. Storey, en- 
tomologist of the Egyptian Ministry of Agriculture, and 
C. B. Williams (Eltringham 1923, Withycombe 1923-b, 
1924), who found it near Cairo, in the dust accumulated on 
the floors of desert caves or under rocky ledges and suc- 
ceeded in rearing the imago. This proves to be a Crocine 
Nemopterid, to which Withycombe (1923a) has given the 
name Pterocroce storeyi. Storey reared a few adults from 
larvae taken about 1915 from a cave some four miles from 
Wadi Digla, where Williams obtained his specimens in 1922. 
Eltringham and Withycombe have published excellent fig- 
ures of the larva, (one of which is here reproduced as Fig. 
1), and the latter has also described an allied form, Nina 
joppana, males and females of which had been reared in 
1921 by Aharoni (Blair 1920-1921) from larvae taken in 
the sand of caves near Jaffa, Palestine. The larva of this 
species closely resembles that of Pterocroce storeyi but has 
a distinctly shorter “neck.” 
Both Eltringham and Withycombe seem to believe that 
the introduction of the new name Pterocroce storeyi is jus- 
tified for the insect reared by Storey and Williams. Eltring-
