THE WINGS OF MECOPTERA 



305 



In the hind wing of this specimen vein Cui anastomoses with vein M4 

 for a short distance. Vein Cui bears one accessor}- vein on the right side, 

 but is unbranched on the left side. 



Dr. Fitch gave the popular name Earwig-fly to this insect on account of 

 the stout pair of forceps at the caudal end of the abdomen of the male.

The genus Notiothamna was established by McLachlan ('77) to receive 

 a remarkable insect from Chili , which he named Notiothamna Reedi. Only 

 a single mutilated individual was known, the head and pronotum of which 

 were nearly entirely destroyed. But the form of the wings and the presence 

 of a well-developed, nearly semi-circular lobe at the base of the inner margin 

 of the fore wings indicated that the species was allied to Merope tuber. 

 McLachlan gave a figure of his specimen, which was carefully copied by 

 Brongniart ('93). I reproduce Brongniart's copy, as it is better suited for 

 reproduction by photoengraving than the original (Fig. 318).
