ccii Proposed Division of Neuroptera 



Imago having scarcely any similarity to either larva or pupa, with 

 transverse head, deeply received into the well-developed pro- 

 thorax ; the wings are nearly alike, recumbent, and deflected, 

 numerously veined, but not finely reticulated, the hind-wings 

 are longitudinally folded. 

 These insects appear further divisible in accordance with the fol- 

 lowing formula. 

 Ocelli 3 : — 



Body clothed with hair Ithoneshle, Newm. 



Body naked : — 



Antennae simple Corydalid^e, Newm. 



Antennas pectinated ChauliodesiDjE, Nwm. 



Ocelli SiALiDiE, Leach. 



Obs. 1. — The Ithonesidae appear to be a numerous group, confined 

 to New Holland. Ithone is the only genus described, but there are 

 many species, and these very dissimilar, and likely to be generically 

 subdivided when we become better acquainted with the entomological 

 productions of the wonderful country in which they are found. 



Obs. 2. — In this division must also be placed, at least provisionally, 

 the curious Spanish infect, Dilar Nevadensis of Rambur, which has 

 much the appearance of a Hemerobius, but the male has pectinated 

 antennae, and the female a very long exserted ovipositor : the antennae 

 of the male are rather longer than the body, and have twenty-six arti- 

 culations, each of which is furnished with a single long branch at its 

 extremity, these gradually increase in length from the base to the tenth 

 articulation, and from this decrease to the tip. The mouth has not 

 been examined, and the economy is entirely unknown. Not being 

 able to associate this insect with any other division of the Corydalina, 

 I propose to institute the division Dilarid^e, Newm. 



Characters of Phryganeina.* 

 Larva aquatic, much resembling in figure that of the Lepidopterous 

 genus Psyche ; the head is small, without antennae, and having 

 corneous mordent mandibles ; the leg-bearing segments are of 

 equal development, and have a coriaceous skin ; the legs are 

 short ; the abdominal segments are covered with a soft skin, 

 and are inclosed in a case constructed of extraneous materials, 

 after the manner of the genus Psyche and other sacktriigers 



* I think the name of the genus should have been Phryganodes, i. e., consisting of 

 fragments of twigs, or like a little bundle of dry twigs, and ihe group would in that 

 case have been Pkryganodeina : the termination I have given I am aware is unclassical
