hyaline, or slightly fusceScent, with rather darker nervures, and somewhat 

 glossy, immaculate. 



Taken within the metropolitan district, in June and July, not 

 common.

 He. confinis. Steph. Catal. 312. No. 3488. 



Testaceous-brown: eyes black ; antennae rather short and pitchy; legs testa- 

 ceous ; wings hyaline, slightly fuscescent, shining and immaculate, with 

 pale fuscous nervures. 



Also found within the metropolitian district, in June, but rarely. 



Family III.— PSOCID.E, Leach. 



Antenna rather long and slender, filiform, or setaceous, the articulations either 

 few in number and very indistinct, or numerous and somewhat moniliform : 

 palpi two or four, labial sometimes wanting : co//ar very small : thorax a 

 little tubercular : wings four, or wanting, anterior ample, elongate, with 

 a few irregular longitudinal nervures, and a few transverse ones ; posterior 

 pair usually small : legs simple : tarsi with two, three, or five joints : body 

 soft. 



As formerly mentioned, the insects of this family differ consider- 

 ably in habit from the others of this section ; their antennae are 

 much elongated, the collar very small, the wings narrow and elongate, 

 •with but few irregular, waved, and radiating nervures, and one or 

 two transverse ones ; the posterior wings are usually much smaller 

 than the anterior, and the insects are of small size : they are found 

 on the trunks of trees, old walls, amongst lichens, &c. during the 

 summer, and are very active : their larvas are active, and have con- 

 siderable resemblance to the perfect insect, except in being destitute 

 of wings. The indigenous species may be thus divided into genera : 



Alati ; tarn articulis 5-que : ..... 21. Coniopteryx. 



articulis 2.bus : ..... 22. Psocus. 

 Apteri ; tarsi articulis 3-bu8 : . . • .23. Atropos. 



Genus XXI.— CONIOPTERYX, Leach. 



AnienncE long and filiform, composed of from 20 to 40 pubescent, somewhat 

 moniliform, distinct articulations : labrum semicircular, slightly concave 

 before: maxillary pa'pi long, porrect, forming a kind of beak, 5-jointed :
