168 ME. E. m'lachlan on the neuropteea op 



dinal line on the scutellum, continuous with the black median line 

 of the anterior lobe. Metanotum likewise with black lines in the 

 sutures, and spots on the lateral lobes. Pectus and lileurae un- 

 spotted. 



AMomen marked with black (indistinctly in the dry insect). 

 Legs green, with microscopic black hairs ; tarsi dusky ; claws 

 much dilated internally at the base, the apical portion slender and 

 strongly curved. 



Wings broad, acute and almost angulate at the extreme tips. 

 In the anterior pair there is a small blackish line close to the 

 base of the costa, in front of a black tubercle at the extreme base ; 

 another blackish tubercle at the extreme base of the radius ; reti- 

 culation dark green, with short black hairs ; most of the trans- 

 verse nervules &c. marked with blackish at each end (as also in 

 the posterior); gradate nervules wholly black, 8 in the inner, 

 9 in the outer series; partition nervule of the third cubital 

 cellule ending far beyond the nervule above it : pterostigma 

 dusky. 



[In the living insect the eyes are noted as coppery-green. The 

 abdomen is intricately marked with black, each segment having a 

 transverse fascia augulaterl on each side, and a lateral line 

 emitting from the middle a finer line directed forwards and in- 

 wards, &c.] 



Expanse 32-33 mm. Breadth of anterior wing 5|-6 mm. 



Madeira {WoUaston, one $ in my collection). 



Canaries : about pine trees near Aguamansa, Teneriffe, 4000 

 feet, 16th December {Eaton, one ? ). 



The example given to me by "Wollaston is much discoloured. 



It is dif&cult to assign to this a position with regard to Euro- 

 pean species ; perhaps in some respects it might be placed near 

 Ch.formosa.
