APPLE LEAVES HEMEROBIUS SPECIES. \)9 



wholly immaculate. Its spotted wings at once separate it from the following 

 species, which differ from all our other lace-wings with three discoidal veins hy 

 having, like this species, an anastomosing veinlet running inwards from the 

 base of the first discoidal. This species occurred upon pine bushes the latter 

 part of May. 



The Pine-bush lace-wing (//. Pinidumus). Wings hyaline, slightly tinged 

 with smoky, the marginal dots all of a uniform brown color; veins of the fore 

 wings white with brown rings; veinlets black margined with dusky, forming 

 a few brown spots, of which three or four form a curved row across the disk. 

 Body pale dull yellow, sides of the thorax brown. Wings expand 0.45. This 

 is nearly related to tutatrix, from which, however, it is readily distinguished 

 by having a slender anastamosing veinlet connecting the second longitudinal 

 vein with the base of the third longitudinal or the first of the three which 

 branch from the rib-vein. It may frequently be met with upon pine bushes, 

 from May till the last of July. 



The Glassy lace-wing (//. hyalinalus) is much like the preceding, but the 

 wings are more clear and glass-like, their veins very faintly mottled with dusky 

 the veinlets colorless instead of brown and not in the least margined with 

 dusky, and in the middle of the inner margin forward of the medial series of 

 veinlets, arc two or three veinlets connecting the first longitudinal vein and its 

 branches with the margin. The marginal dots are unicolor. Wings expand 

 0.45. Possibly this is only a variety of the preceding. It occurs with it upon 

 pine bushes in May, June, and July. 



The Little friend lace-wing (//. amiculus). Two discoidal veins only 

 arising from the inner rib-vein, as in the remaining species. Wings hyaline 

 mottled with smoky dots and irregular unequal spots; margin of the fore 

 wings with a regular series of black dots, one between the apex of each of the 

 veins, but none upon the tips of the veins; veins brown dotted with black, 

 more conspicuously so in the axilla and the area outside of the rib-vein; veins 

 of this last mentioned area (the costal) forked; the two rib-veins rather dis- 

 tant from each other, with an anastamosing veinlet towards their base; second 

 discoidal fork anastamosing with the outer branch of the first near its base, 

 then forking, with the outer fork anastamosing twice with the rib-vein and 

 once with the inner fork; slightly forward of this last is another veinlet con- 

 necting the inner fork of the second discoidal with the outer fork of the first 

 discoidal, and a second, commonly continuous with this last, connecting the 

 outer with the middle fork of the first discoidal; another veinlet is situated 

 halfway between this and the base of these forks, which is the first of a series 

 extending inwards and bordered with dusky, which color is continued onwards 

 to the inner margin; there are also three veinlets towards the base. The hind 

 wings are hyaline and without spots or veinlets; the margin has a dot between 

 the tip of each vein. Body dull brown, antennae yellowish, legs dull white. 

 Wings expand about 0.42. Taken from May until October, on peach trees 

 and on wild shrubs, both in this State and Illinois. 



The Western lace-wing (//. occidentalis) has the wings hyaline and not 

 mottled with smoky dots or clouds, but adorned with two faint parallel lines 

 of a more dusky tinge in all the cells; margin dusky; veins and veinlets ro- 

 bust, black; a black dot on the margin between the tips of each of the veins; 

 outer fork of the first discoidal vein anastamosing with the rib-vein near its 

 base instead of with the second discoidal as in the preceding species, the other
