Characters of the Order. 



" Wings much deflexed, with strong ncrvures, hispid or hairj', the lower 

 wings plicate : antenna: inserted between the eyes, often very long, 

 composed of an inlinity of joints : ytei elongate, spinulose: tarsi 

 elongate, tive-jointed ; the last joint with two small nails : larva 

 elongate, agile, somewhat cylindric, com])osed of twelve joints, the 

 three first harder than the rest, and each bearing a pair of feet; the 

 last segment with two hooked processes. It inhabits tvdjes con-

 fect insect, shut up In the tube it inhabited whilst a larva, but having 

 the power of motion prior to its emerging from the water (in which 

 it resides), for the purpose of changing into the fly-state." 



Genus 375. PIIRYGANEA. Liimi, Fabr., Geoff., Latr., Leach. 



Dr. Leach has paid the greatest attention to the insects of this 

 Order, liaving collected them with unexampled assiduity in various 

 parts of England, Ireland, Scotland, and Wales. The Doctor 

 will probably publish a work on this Order. When published, I 

 must refer the student to it for a further account of the genera. 



Fam. I. Leptocerid.e. Leach. 

 Antenna much longer than the whole body. 



Genus 376. LEPTOCERUS. Leach. 



Antennae simple, not denticulated. 



.*;p. 1. Lept. interruptus. 



Phryganea interrupta. Fahr. 



Inhabits Great Britain. It is found in great plenty near Luss, on the 

 banks of Loch Lomond, on the margins of rivulets at Dreghorn 

 near Edinburgh, and near Carlisle in northern England. It occurs 

 during the day-time on the smaller branches of trees, and in the af- 

 ternoon flies about in great abundance, in flocks.
