HYDROPSYCHID.E. APHELOCHEIRA. 179 



N. G. (555.) subnebulosus. Steph. Catal. 317. No. 3598. — Am. subnebulosus. 

 Steph. Nomen. 2d edit. col. 119. — Pol. multiguttatus. Curtis, fol. 544. 



" Fuscous^ iridescent: antennae nearly as long as the superior (anterior) wings 

 in the male, spotted or annulated with ochre ; superior (anterior) wingg 

 with innumerable ochreous spots, with a white dot on a fuscous space on 

 the interior margin, and an oblique line on the disc ; posterior tibiae brown, 

 especially the upper side in the male." — Curtis, I. c. 



Also found, occasionally, within the metropolitan district, in June, 

 and not uncommon in Scotland, in July. 



Genus XVI.— APHELOCHEIRA* mihi. 



Antenna rather shorter than the wings, slender, placed somewhat remotely, 

 and distinctly serrated within: palpi slender, maxillary ovate, the basal 

 joints of nearly equal length, the terminal one scarcely longer than the 

 others united, transversely wrinkled : head densely pilose on the crown : eyes 

 globose : thorax short, ovate : wings ample, broad, anterior a little elongate, 

 narrowed at the base, expanded near the apex, which is obtusely rounded; 

 towards the tip are one or two very faint transverse nervures, but no vestige 

 of one on the costa ; hinder wings short, ovate, also with few indistinct 

 transverse nervures : abdomen rather short and robust, compressed, the tip 

 with two short horny processes in the males, obtuse in the females : legs 

 rather short ; anterior tibice slender, with two short spurs at the apex, inter- 

 mediate and posterior each with a pair of spurs at the apex, and a second 

 pair below the middle ; hinder tibiae rather stoutest and longest. 



The brevity of the antennae and wings, combined with the breadth 

 of the latter, the few transverse nervures with which they are fur- 

 nished, of which there are none about the middle of the costa ; the 

 simple unarmed anterior tibiae, &c. sufficiently point out their 

 distinction from the other genera of this family ; the wings are of 

 sombre hue, more or less faintly freckled with a pale tinge, in some 

 cases amounting almost to spots, as in the genus Thilopotamus ; but 

 the general habit of the insects demands their separation from those 

 insects.
