FAMILY 11. 



PLANIPENNES.(l) 



This family comprises those Neuroptera in which the antenna, 

 always multiarticulated, are much longer than the head, without 

 being subulate or styliform. Their mandibles are very distinct; 

 their inferior wings almost equal to the superior ones, and extended 

 or simply folded underneath at their anterior margin. 



Their wings are almost always much reticulated and naked; their 

 maxillary palpi are usually filiform or somewhat thicker at the ex- 

 tremity, shorter than the head, and composed of from four to five 

 joints. 



I will divide this family into five sections, which, by reason of 

 the habits of the Insects that compose them, form as many small 

 sub-families. 



1. The Panorpat^ of Latreille, which have five joints to all the 

 tarsi, and the anterior extremity of their head prolonged and nar- 

 rowed in the form of a rostrum or proboscis. 



They constitute the genus 



Panorpa, Lin. Fab. 

 Where the antenna are setaceous and inserted between the eyes; the cly- 

 peus is prolonged into a conical, corneous lamina, arched above to cover 

 the mouth; and the mandibles, maxillx and labium are almost linear. They 

 have from four to six short, filiform palpi. 



Their body is elongated, the head vertical, the first segment of the trunk 

 usually very small, in the form of a collar, and the abdomen conical or al- 

 most cylindrical. 



There is much difference between the two sexes in several species. 

 Their metamorphoses have not yet been observed. 



P. communis, L. From seven to eight lines in length; black; rostrum 

 and extremity of the abdomen russet; wings spotted with black. — On 

 hedges and in woods. 



2. The Myrmeleonides, which also have five joints in the tarsi, 



(1) Flat- winged.
