92 APPLE LEAVES — HEMEB.0BIUS SPECIES. 



black stripe the whole length on its outer side. Thorax with an impressed 

 transverse line forward of the base of the first segment, and a longitudinal on e 

 on the anterior elevated lobe of the second segment. Legs white. Wings very 

 slightly angulated at their tips; stigma marked by a slight opacity; veinlets 

 dusky ox black. Wings expand 1.10. Taken the middle of July. 



41. (40 ) A black dot on the outside of the first joint of the 

 antennse at its tip. 



The Dotted-iiorned Golden-eye ( C. punctic-rnis} is perhaps only a va- 

 riety of the preceding, as it corresponds with it in all respects, except that the 

 basal joint of the antennas has only a black dot at its apex on the (niter side, 

 and there are no dots on the edge of the sockets of the antennas ; the first seg- 

 ment of the thorax has two transverse impressed lines and a longitudinal one 

 behind the middle. The abdomen has a brown stripe above on each side. Wings 

 expand 1.15. This also occurs in the middle of July. 



42. (39.) Antenna? pale. 



The Consumptive Golden-ete (0. tabida) is pale green, almost white; 

 the head is white and without spots, except a slight discoloration on the cheeks 

 in some individuals which commonly disappears in the preserved specimen; 

 the antennas are white their whole length; the thorax is white along the mid- 

 dle, and pale green upon each side; the wings are obtusely angulated at their 

 tips, their veins white tinged in places with green, the veinlets greenish white, 

 their ends black, the two series towards the tip entirely black. Wings expand 

 0.95. Occurs the fore part of August. 



The Lace-wing flies pertaining to the genus Hemerobius differ 

 from each other much more than these we have been considering. 

 They are generally of pale dull colors, but vary greatly in size, 

 in the veins and spots upon their wings, &c. Most of the fol- 

 lowing species have three longitudinal veins branching from the 

 rib vein towards its base on the inner side ; the three last species 

 however, have only two such veins, whilst the first has several, 

 and the second has four. 



The Freckled lace-winc (Flemerobius irrara'us, Say) is black and hairy 

 with a pale yellowish stripe on the middle and another upon each side of the 

 thorax. The head, scutel and under side of the body is also pale yellowish. 

 The wings are hyaline and glassy, with numerous irregular blackish spots and 

 dots, those on the margin larger and alternated with whitish spots, and there 

 is a largish darker colored spot near the middle and another towards the tips 

 of the inner longitudinal veins, situated upon their connecting veinlets. The 

 veins are black alternating with white. The hind wings are without spots ex- 

 cept in the region of the stigma; their veins are black with only the marginal 

 and rib veins alternating with white. The wings expand from 2.25 to 3.20
