APPLE LEAVES HEMEEOBIUS SPECIES. 95 



three discoidal vein^a by having, like this speeies, an anastamosing- veinlet rtmning in- 

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

 t.he latter part of May. 



The Pine-bush lace-winq (H. 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 (H. hyalinatus) 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 mid- 

 dle of the inner margin forward of the medial series of veinlets, are 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 triend lace-wing (H. 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 distant from each other, with an anastamosing vein- 

 let 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 

 connecting thfe inner fork of the second discoidal with the outer fork of the first dis- 

 coidal, and a second, commonly continuous with this last, connecting the outer with 

 the middle fork of the first discoidal; another veinlet is situated half way 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 Westebit lace-wing (H. occidenialis) has the wings hyalineand 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 robust, black; a black dotoj 

 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 veinlets similar in situation to those of the pre-
