100 MANDIBULATA. NEUROPTERA. 



some of a fainter hue on the hmder margin ; posterior pair with the costal 



edge irregularly spotted and marked with fuscous. 

 The fuscous markings on the wings vary considerably : in some examples the 



wings are very much spotted, especially on the inner margin ; in others 



nearly, or quite, immaculate; others have the lower pair with a deep brown 



central dot. 



Rather a local species, but found in great abundance in some 

 places, especially on the margins of a brook on the side of a copse 

 near Colney Hatch^ in June ; also found near Halifax and 

 Warwick. 



Genus XVIII.— DREPANEPTERYX, Leach. 



Avtennw rather shorter than the body, placed a little remotely, stoutishj 

 moniliform, the basal joint very robust : palpi unequal ; maxillary long and 

 slender, the terminal joint subfusiform, acute ; labial very short : labruvi 

 rounded on its outer edge: head transverse: eyes moderate, prominent; 

 ocelli wanting : collar ample : thorax broad : wings broad, detlexed during 

 repose, scarcely pubescent ; anterior pair with very numerous dichotomising 

 nervures, united by two longitudinal series on the costal area, and three 

 somewhat irregularly-placed oblique series on the disc, exclusively of the 

 pair common to all the family; much dilated and rounded at the base, the 

 apex recurved ; the hinder margin deeply excised, and, with the recurved 

 apex, forming an acute hook, the base of the inner margin with a mucro- 

 nated process ; posterior pair shorter, with fewer nervures, somewhat 

 lanceolate-acute, the hinder margin waved : abdomen compressed : legs long 

 and slender. 



This singular-looking genus is very conspicuous from the form of 

 its anterior wings, which are irregularly excised and somewhat falcate 

 on the hinder margin ; they are considerably reticulated, and differ 

 much from those of the two following genera, especially on the costal 

 edge of the anterior wings, as may be seen by comparing the figures 

 in pi. xxxiii. f. 1, and pi. xxx. £ 3 and 4. One indigenous species 

 only is known.
