2731 THE LARVAE OF THE COCCJNELLIDAE— GAGE 41 



one to eight bear the dorso-lateral parascoli, the first and fourth are white 

 and the remainder are brown to dark tan-colored. The ninth abdominal 

 segment is longer than wide; its caudal margin is acutely rounded; its 

 dorsal surface is brown colored, chitinized, and bears many chalazae and 

 small setae. The lateral aspect of segments one to eight is provided with 

 distinct lateral strumae, those on segments one and four are white. There 

 is a small paralateral verruca ventrad of each lateral strumae. The lateral 

 aspect of the ninth segment bears chalazae. The sterna of segments two 

 to nine are provided with four chalazae arranged in a transverse row on 

 each segment, the sternum of the first segment has only two chalazae 

 present, the ventrolaterals are wanting. 



Adalia Mulsant 



This genus is represented in the material studied by a single species. 



Adalia bipunctata Linn. — The body is elongate, oval in outline, the 

 third and fourth abdominal segments are the widest. The general color 

 is dark brown to bluish-gray, mottled with light yellow or cream-colored 

 spots. The dorsal part of the head is dark brown to black and heavily 

 chitinized, while the ventral portion of the front and clypeus is white or 

 cream-colored. The epicranial stem is absent and the epicranial arms 

 curve broadly laterad and mesad to the pretentorinae, giving the front a 

 more or less circular appearance, then extend laterad from the pretentorinae 

 toward the antacoriae near which they become obsolete. The mouth is 

 directed cephalo-ventrad. The prothorax is crossed longitudinally by a 

 median and two lateral yellow stripes. The dorsal shield is not united to 

 the meson of the mesothorax and metathorax and the two portions are 

 separated by a cream-colored area. The lateral aspect of the prothorax is 

 glabrous. The cephalic portion of the mesothorax and metathorax is also 

 glabrous; while the caudal portion is large and bears a small but distinct 

 struma on each segment. The mesothoracic and metathoracic spiracles 

 are located in the coriae between the segments. The thoracic sterna are 

 distinct, each sternum bears a pair of small verrucae near its cephalic 

 margin. The coxacoriae are distant. Abdominal segments one to eight 

 are each provided with a transverse row of four strumae on the tergum. 

 The mesal portions of the dorsal strumae of the fourth segment are white, 

 while the lateral portions are brown, the dorso-lateral strumae of the first 

 segment are surrounded by a distinct white area, and the dorso-lateral 

 strumae of the second to the eighth segments are surrounded by a much 

 smaller white area. Each struma is provided with three to five prominent 

 chalazae. The lateral aspect of segments one to eight is yellow and the 

 strumae are brown except on the fourth segment where they are light 

 yellow. There is a small but distinct chalaza on each segment ventrad of 

 the lateral strumae of segments one to eight which is surrounded by a few
