46 MODERN CLASSIFICATION OF INSECTS. 
vol. xv. p. 511.) The figures which L. Guilding sent to the Linnzan 
Society, in illustration of the history of this curious insect, were not 
published. Iam able, however, to give a figure (63. 20.) of a larva 
contained in the collection of the Rev. F. W. Hope, which is evidently 
that of an Ascalaphus. ‘The head is very flat, deeply emarginate be-

pendages on each side. 
The family HEMeRopitp® * (Hemerobidee Leach) is composed of

during life; the ocelli are mostly obsolete, but they exist (three in

lip large, and rounded at the anterior angles; the jaws (fig. 64. 3.) 
horny and acute, with a tooth below the centre; the maxille (jig. 
64. 4.) long, with the inner lobe broad and ciliated, and with a broad, 
compressed, hirsute external lobe ; the lower lip (fig. 64. 5.) is entire 
and rounded, arising from a distinct leathery mentum ; the prothorax
