LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE. — XVIII. 



nv HARRISON G. DYAR, WASHINGTON, D. C. 



Haematopi^ grataria Fab. Riley h.is de- 

 scribed the mature larva and pupa and given 

 a short account of the habits, which has been 

 quoted bv Packard. 



Egg. Laid in a row side h\ side on the 

 edge of a leaf or .stem. Elliptical, flattened 

 above and below, wedge shaped, the larger 

 end moderately truncate; marked like a 

 thimble all over, the reticulations broad and 

 rounded, the cell areas depressed, forming 

 rounded shallow pits. The pores at the 

 angles of the reticulations show in certain 

 lights as white dots. Pale yellow, later turn- 

 ing red. Size .6 X .4 X .3 mm. 



Stage I. Head rounded, slightly bilobed, 

 erect, free, dull black, the face whitish, ir- 

 regularly bordered, looking like four conflu- 

 ent patches about the clypeus ; antennae 

 small ; width about .25 mm. Body moderate, 

 normal; white, a little sordid; a broad red- 

 brown subdorsal band, becoming, behind 

 joint 5, a broad single dorsal band, cut on 

 each segment by a posterior cuneiform patch 

 of the ground color dorsally and a small 

 anterior one subdorsally on each segment. 

 A similar broad subventral band, more dif- 

 fuse and a little paler, the pair obscurely 

 joining in the centers of the medial seg- 

 ments. Tubercles small, dark; setae short, 

 slightly enlarged at tips; shields uncornitied, 

 concolorous ; feet pale. 



Stage II. Head squarish bilobed, a dis- 

 tinct shallow vertical notch ; free, higher 

 than joint 2 ; brown mottled, a white patch 

 across the lower part of clypeus, a yellowish 

 white vertical band and broader, irregularly 

 edged patch behind the ocelli ; width .35 

 mm. Body somewhat thick, the segments 

 slightly enlarged centrally and a little angu- 

 larly bent, subannulate, tubercles and setae 

 obsolete. Greenish white, marked with dark 

 reddish brown. At the ends a broad sub- 



dorsal band, obscurely geminate, becoming 

 centrally a series of large V marks, one on a 

 segment, the points directed forward, joined 

 by narrow addorsal and sulidorsal lines, in 

 all five such marks, situated on joints 5 to 9. 

 Sides slightly marked with olivaceous in the 

 folds. A broad subventral band, obscurely 

 darker, running the whole length and partly 

 olivaceous, not so sharply defined as the 

 dorsal marks. Feet pale outwardly. A dark 

 lateral shade on joint 5. 



Stage III. Head as before, the brown 

 color darkened, spotted, the light color yel- 

 lowish-white; width .55 mm. Body yellowish 

 white in ground, but largely obscured. Sub- 

 dorsal line pale brown, sharply, though a 

 little pulverulently edged, continuous, ob- 

 scurely cutting the oblique, velvety brown 

 bars of joints 5 to 9, into which the former 

 V-marks are now divided. Lateral band vel- 

 vety brown, representing the oblique bars at 

 the extremities. A faint, geminate, pale 

 brown, stigmatal band, composed mostly of 

 the prolongations posteriorly of the oblique 

 bars, but a true line at the extremities. 

 Subventral band broad, pulverulently gem- 

 inate, dark brown, widened above centrally 

 on the segments, especially on joint 5, where 

 it forms a large spot. Feet pale outwardly. 

 Tubercles and setae obsolete. Body moder- 

 ate, rather robust, the segments slightly 

 swollen centrally. 



Stage IV. Head rounded, squarish above, 

 broad, lobes full at cheeks, held obliquely, 

 free from and higher than joint 2; densely 

 dotted with blackish brown, leaving a small 

 white vertical streak on the lobe and a space 

 behind the ocelli, the latter reticulate; width 

 .8 mm. Body moderate, a little tapering 

 before, not so behind, marked as befoi'e, but 

 the brown marks darker and more extensive 

 so that this color predominates, making the
