60 MANDIBULATA. NEUROPTERA. 



Fuscous, slightly shining; abdomen pale, the apical segments and the margins 

 of the central ones dusky-brown ; legs pale ; filaments pale lurid, immacu- 

 late, joints short ; wings transparent, costa faintly yellowish. 



Found within the metropolitan district. 



Sp. 16. minor. Obscure fusca, segmentorum marginibus rufescentibus, pedihus 

 pallidis, alls angiistis hyalinis costa concolore. (Exp. Alar. 34 liu.; long. corp. 

 y lin. ; 1. set. 3 lin.) 



Eph. minor. Steph. Nomen. 2d edit. Appendix. 



Slender, dull fuscous ; segments of the abdomen with their margins slightly 

 reddish ; legs very pale ; filaments lurid, immaculate ; wings narrow, 

 transparent, costa concolorous. 



Taken at South Lambeth, in June. 



Gekus IV.— CiENIS mihi. 



/fead broad, short : e^e* small, remote, rounded: <Aor-a.r large, ovate : wings 

 two, short, broad, with numerous longitudinal nervures, and two or three 

 transverse ones near the costa : abdomen about as long as the thorax, obtuse 

 at the apex, and terminated by thi-ee filaments of very variable length in the 

 respective species : anterior legs in the male long, their femora thickened, 

 tibise and tarsi slender, four hinder pair short, rather slender. 



This genus is readily known by the brevity of its wings and abdo- 

 men, the latter not exceeding the length of the thorax, and scarcely 

 extending beyond the outer anal edge of the expanded wings ; its 

 apex is, however, furnished with three setae, or filaments, by which 

 character alone it may be distinguished from the two following 

 genera. The species appear to be rather scarce, or are very local.

Amongst the smaller species of the genus (family) with the entire body, and 

 the anterior wings black ; the posterior wings white. 



Probably the pseudimago of one of the foregoing species.
