LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE.— XL. 



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



Lycia cognataria Guenee. The ^^^ has been noticed by A. P. W. Cramer and 

 there are several good descriptions of the mature larva extant, besides a poor 

 figure, published by Lintner. The larval stages have not been before noticed. 

 I am indebted to Mr. H. H. Lyman of Montreal for the eggs, which hatched 

 before arrival. The larvae fed readily on maple, but are, apparently, rather general 

 feeders. 



Egg. Elliptical, roundedly and distinctly flattened above and below, ends rounded and 

 much alike, no distinct flattening of micropylar end nor marked depression of the other end. 

 Reticulations distinct, in longitudinal rows, forming waved ridges, the cross striae being a 

 little weaker than the longitudinal lines. Reticulations confused at the ends, and less 

 strongly marked. Size .6 X .4 X .3 mm. "Color bright green. Laid loose in large num- 

 bers " (Lyman). 



Stage I. Head rounded, bilobed, full, bhickisii oxer the lobes, dull sordid on clypeus 

 and mouth ; sutures of clypeus deep, well marked; width about .3 mm. Body normal, mod- 

 erately robust, whitish, becoming sordid green from the food ; a dull purple, broad, subdor- 

 sal band, obscurely joined intersegmentally on the abdomen and completely so on joints 

 10-13, separate on thorax; a broad, diffuse, dull purplish ventral band, later resolving into a 

 series of medioventral patches. Thoracic feet black, abdominal ones dark outwardly. 

 Tubercles black, small, noi'mal ; setae inconspicuous. Cervical shield colored like the body, 

 undifferentiated, but anal plate and anal leg shields triangular, broadly blackish edged.
