5. OPHEKOPTKRA Hubn. 



Verz. 321. 1818. 



Type brumatd L. 



Palpi short, porrect, slender ; antennte of % dentate, with fascicles 

 of hairs on each segment; antennse of 9 filiform; front smooth; 

 tongue short, weak; hind tibiae with all spurs; fore wings of <? 12 

 veins, one accessory cell, 6 long stemmed with 7, accessory cell large, 

 7, 8, 9 and 10 arising from at or near its end ; hind wings 8 veins, 

 3 and 4 wndely separate, 5 nearer 4 than 6, 6 and 7 long stemmed, 

 8 with cell to beyond middle ; wings of 9 partly developed extend- 

 ing about length of thorax ; body of 9 somewhat vermiform ; 

 frenulum wanting. 



It is doubtful whether this species has even been taken within our 

 limits. I have never seen it myself to be certain of it, but Staud- 

 inger catalogues it, doubtfully from Greenland. 

 Species. — 0. boreata Hiibn. 



6. PARAPTERA n. gen. 

 Type danbyi Hiilst. 



Tongue wanting ; palpi short, slender ; antennse of S with seg- 

 ments round, even, each with two slender fascicles of hairs ; 9 an- 

 tenniB filiform ; clypeus untufted ; thorax and abdomen untufted, 

 in 9 more closely joined, somewhat vermiform ; hind tibiae wnth one 

 pair of spurs only, or very rarely with upper pair slightly developed ; 

 fore wings of S 12 veins, with one accessory cell, 5 nearer 4 than 

 middle of cell, 6 long stemmed with 7, cell large, la and 16 both 

 present, strong ; hind wings 5 much nearer 4 than middle of cell, 6 

 and 7 long stemmed, 8 with cell more than half its length ; 9 with 

 wings partly aborted, these reaching somewhat beyond thorax, and 

 being about the size of the ordinary wings on emergence from pupa; 

 frenulum wanting. 



Very close to Opheroptera, differing in tongue, antennae of S , and 

 spurs of hind tibiae, though in none of these in a very mai'ked 

 degree.
