1903] DYAR:— XORTH AMERICAX GEOMETRIDAE 1 69 



Stage III. Head rounded, flat before, broadly shallowlv bilobed ; grayish, speckled 

 with black, thickly so over the apex and in a patch on each side of clypeus above; a black 

 patch at base of antennae; width .9 mm. Body cylindrical, moderate, normal, tubercle ii of 

 joints 5 to 7 and 12 forming high cones, the rest elevated roundedly. Feet of joints 2 and 3 

 held appressed, those of joint 4 erected. Shining bronzy black with scarcely any marks. 

 Traces of a whitish addorsal line and irregular pale areas stigmatally anteriorlv, largest on 

 joints 5 and 6 and traces of white dotted supra- and substigmatal lines. Feet all black; setae 

 moderate, pointed, dark. 



Stage IV. Head squarely rounded, lobes separated by a wide low notch, flattened 

 before, depressed at apex of clypeus; clypeus reaching two thirds to vertex, the paraclypeal 

 pieces nearly reaching vertex; light gray with many irregular crinkled black spots irregu- 

 larly vertically arranged on the sides and partly confluent behind the vertices of the lobes ; 

 sutures of mouth black marked; width 1.6 mm. Body cylindrical, normal, robust, not 

 elongated; tubercles prominent, especially ii on the raised part of the abdomen and forming 

 a stout cone on joint 12. Blackish, especially across the centers of the segments, a rather 

 broad whitish addorsal line, broken and obscured centrally, rather distinct on the thorax 

 and before tubercle ii on joint 12. Sides yellowish blotched, scarcely defining subdorsal, 

 suprastigmatal, and two subventral lines which are irregularly traceable; a conspicuous black 

 patch behind the spiracle on joints 6 and 7, slightly indicated on other segments. Venter 

 blackish, pale medioventrally and between joints 10-13. Thoracic feet black, abdominal 

 ones dark, the plates of joints 13 lighter. Cervical shield not developed. Tubercles black, 

 single, normal, dark, pointed. 



Stage V. Head rounded squarish, scarcely bilobed, the vertical notch obsolescent, flat- 

 tish before, the sutures at apex of clypeus depressed; surface shagreened ; vellowish, mottled 

 and spotted with brown, heaviest on sides of lobes and in clypeal depression; width 2.3 mm. 

 Body normal, robust, tubercles roundedly produced, smooth, ii the largest, on joints =; to 7 

 forming distinct cones, on 12 situated on a slight dorsal prominence, normal, iii to v closely 

 surrounding the spiracle, two tubercles representing vi ; no cervical shield, anal shields 

 developed, triangular, but concolorous and not corneous. Skin minutely spinulose ; spira- 

 cles large, black rimmed; setae distinct, dark. Varies from sordid gray to green without 

 distinct lines or strong markings. There is a general indication of longitudinal lines, pale, 

 marked with fine brown dottings. These lines are addorsal, subdorsal, suprastigmatal, and 

 two subventral, but all are ill defined, especially the subventral ones. Feet pale. 



Plpa. Cylindrical, normal, abdomen tapering, with three movable incisures; cremaster 

 two stout spines joined at the base into a flatfish plate; cases wrinkled ; abdominal segments 

 coarsely punctured. Length 18, width 5 mm.
