Stage II. 



Head slightly yellowish; body smooth, shiny, cylindrical, green, with prothoracic 

 "ears" sharply pointed. Length 6 mm. 

 Stage HI. 



Very similar to preceding stage; traces of reddish on dorsum and rear segments; 

 faint red dorsal and subdorsal spots at the junction of segments. "Ears" very 

 prominent, tinged with red. Length 12.5 mm. 

 Stage IV. 



Head small, well hidden by prothorax which is squarely built with "ears" drawn 

 out into two sharp points ; body cylindrical, green, tinged with rose, which color 

 increases gradually towards the anal segments, until it becomes the prevailing color; 

 anterior margin of prothorax rose; three rose-colored dots on posterior portion of 

 each segment dorsally. Length full grown 30 mm. 



The larva spun up but failed to pupate. 

 Food plants. Ampelopsis; Vitis. 



Eupithecia miserulata Grt. (teste Grossbeck). 



Ovum. Oval, flattened slightly at micropylar end, 4 mm. long; when first laid 

 pale yellow, later light orange. The whole siu-face of egg is faintly sculptured with 

 irregular hexagons. Duration of egg stage about 6 days. 

 Stage I. May 18th. 



Head black; body muddy green, slightly lighter laterally. Length, after feeding 

 a day, 3 mm. 

 Stage II. May 23d. 



Slender, cylindrical, tapering anteriorly; dull yellowish-green, skin granulated; 

 a broad red dorsal stripe tending to diamond-shaped enlargements in centre of each 

 segment; traces of a red subdorsal line on first two segments and a narrow lateral 

 line of similar color. Legs black. Length 5 mm. 

 Stage III. May 26th. 



Pale whitish, markings as before but rather clearer. Length 9 mm. 

 Stage 1 V. May 30th. 



Head small, flat, whitish, with sparse hairs; body tapering anteriorly, rather 

 flat with prominent lateral fold; skin somewhat granulate, whitish; a narrow red- 

 dish dorsal line, and a broad dorsal arrow-shaped mark with apex pointed forward 

 and resting on dorsal line on first five abdominal segments; 6th abdominal with 

 very small arrow-mark; other segments without; a brownish-red subdorsal line, 

 distinct on thoracic segments, very faint on abdominal, where it forms a lateral 

 boundary to the dorsal arrow-marks; a red stripe below lateral fold of skin; ventrally 

 whitish; claspers white. Length full grown 18 mm. Pupation on surface of earth 

 in slight web on June 4th. 



Pupa. WTiitish with legs, antennae, and veins on wing cases marked distinctly 

 in black. Emerged June 16th. 



Food 'plants. Our larvae were fed up on the flowers of dandelion. 

 We discovered similar larvee later on willow and wild cherry, which, 

 however, did not reach the imaginal stage.
