NEUROPTERA. — RAPHIDIIDZ. 55 
caught without difficulty. They appear in great numbers, and live 
but a very short time. The Rev. F. W. Hope possesses a singular 
monstrosity occurring in a specimen of N. coa, in which one of the 
anterior wings is partially undeveloped.* 
It is in this place that I may nctice a singular insect, figured by 
P. Roux in the Annales Sci. Nat., tom. xxviii. pl. 7., under the 
name of Necrophilus arenarius ( jig. 66.1.); but which appears to 
me to be a Neuropterous larva, exhibiting considerable affinity with 
the larve of the Hemerobiide. If the relation of the Nemopterze 
with that family be proved, is it possible that this may be the larva of 
that genus? The body is oval, with a slender linear neck, longer than 
the entire body ; small head; long sickle-shaped mandibles ; two an- 
tenn, and six long simple legs. From its size it might either pro- 
duce a Nemoptera, Bittacus, or Panorpa. 
The family Rapuipup®+ Leach, consisting of the single genus 
Raphidia Zz7., is a singular little group, distinguished by the elongated 
neck-like prothorax, flattened head, and simple fore legs as well as by the 
elongated ovipositor of the female (fig. 66.2. Raphidia ophiopsis 3 ). 
The head (fig. 66. 3. under side of head) is oval and flattened, broader 
than the prothorax, with prominent eyes placed at the front of the sides 
of the head; the ocelli, three in number (but wanting in R. crassicor- 
nis); are placed between the eyes ; the antenne are slender, filiform, and
