Neuropterous genus Ascalaphus. 7 
siderable extent, in which notices are given of the larve 
of eighteen different species of Ascalaphides, which he 
has divided into eight genera founded on the relative 
position of the abdominal spiracles and lobes, the size 
of the teeth of the mandibles, the form of the head, 
the form of the ocular peduncles, the labrum, and the 
palpi. They are named :—1, Haplogenius; 2, Ulula ; 
3, Suphalasca; 4, Helicomitus; 5, Glyptobasis; 6, Hybris; 
7, Theleproctophylla; 8, Puer; 9, Ascalaphus; 10, a 
section termed Holophthalmi. The species of which the 
larve are described are:—1, Ascalaphus macaronius, 
Scop.; 2, A. coccajus, Schifferm.; 3, A. longicornis, L.; 
4, Puer maculatus, Oliv.; 5, Theleproctophylla barbara, 
L.; 6, Hybris subjacens, Walk.; 7, Suphalasca Dietrichie? 
or subtrahens?; 8, Helicomitus ? sp.; 9, Glyptobasis 
imcusans or Ascalaphus cervinus, Ceylon, from Neitner ; 
10, Ulula Macleayana, L. Guild.; 11, U. senex, Burm. ; 
12, Ulula sp., an aurifera, M‘Lach.; 13 and 14, Haplo- 
genius spec.?; 15, Haplogenius sp.; 16, Haplogenius ?. 
Unfortunately no figures are given either of the larve or 
entire insects or of their characteristic details. 
In Mr. M‘Lachlan’s classification of the family 
Ascalaphide, published in the Journal of the Linnean 
Society, vol. xi., p. 219, 104 species of the family are 
arranged under 27 genera, of which 8 were proposed by 
Mons. A. Lefebvre in his memoir on the classification of 
the subfamily in the ‘ Magasin de Zoologie’ for 1842. 
Hight new species of Ascalaphides are described by 
Dr. Gerstaecker, in the 16th annual volume of the 
Mittheil. d. Naturw. Vereins Neuvorpomm. u. Rugen for 
1884, belonging to the genera Haploglenius (from Upper 
Amazons), Ulula (Chiriqui, two species), Suphalasca 
(Cameroons, two species), Dicolops, n.g. (Cameroons), 
and Ascalaphus (Amur and Asia Minor). 
The following is Mr. Staniforth Green’s account of the 
economy of the Ceylonese species, which he has for- 
warded to me with specimens illustrating the history of 
the insect in question :— 
‘‘T wish to call your attention to the larva of an 
Ascalaphus after its first moult. I found it alive about 
the middle of last April with about thirty others on the 
stem of a small lily growing in a pot in my garden; 
they were all lying in a long straight row, overlapping
