8 THE CANADIAN ENTOMOLOGIST. 



Fourth stage. — Head round, leaf green, mouth parts yellow; many 

 short hairs arising from black conical granulations ; width 1.5 mm. Body 

 leaf green with a paler stigmatal line and thickly covered with black con- 

 ical granulations, some of which are larger than others and surrounded 

 by pale green, and all bear short setae. Under the microscope these 

 granulations are seen to arise from swollen green bases and the setae each 

 terminate in a clear spherical drop. 



Fifth stage. — Head small in comparison with body, round, leaf green, 

 thickly covered with conical granulations bearing minute setae, concolor- 

 ous with head, but a few of the larger ones are blue-black; width 2.4 

 mm. Body cylindrical, 5 mm. thick, dark leaf green with a distinct rather 

 broad, yellow stigmatal line strongly shaded with orange, extending the 

 whole length of the body and bordering the anal plate. Six annulets per 

 segment, each annulet containing some twelve conical blue-black granu- 

 lations, surrounded by bluish green at the base. Only a few of these 

 occur below the stigmatal line and then in the middle of the joints where, 

 also, just above the stigmatal line, and sometimes partly below it, the 

 granulations are connected by black, forming incipient transverse bands 

 on the annulets. The granulations are each tipped by a short black seta. 

 Feet and venter pale green, nearly smooth. The body is very minutely 

 punctured between the granulations when seen under the microscope. 



Chrysalis. — Suspended by the cremaster and a long very slight silken 

 loop. Thorax bent up at an angle of 45° with the body, rounded, a slight 

 depression posterior to it ; a long pointed process on the head like a horn, 

 almost continuous with the sides of the body. Wing cases enormously, 

 developed, projecting more than the thickness of the body, evenly rounded 

 along ventral line, flattened laterally and tapering ventrally to an edge. 

 Abdomen cylindrical, tapering; cremaster flattened, a little excavated 

 below. Colour dark pinkish vinaceousf , or pea-greeni, with a greenish 

 dorsal and lateral band, bordered with pale yellow ; ventral line and 

 veins of wing-cases narrowly yellowish. Length 25 mm.; thickness 

 through wing cases from dorsum to venter 10 mm.; thickness of abdo- 

 men posterior to cases 4 mm.; width of body 5 mm.
