279] THE LARVAE OF THE COCCINELLIDAE—GAGE 47 



the caudal margin. The tenth segment is small, cylindrical, and slightly 

 chitinized, with a few fine setae on its surfaces. The segment is usually 

 directed caudo-ventrad. The rectum has been evaginated to form a suck- 

 ing disk. The legs are short and well developed, but do not extend beyond 

 the sides of the abdomen in the adult larvae. The coxacoriae are distant. 

 Hyperaspis signata Oliv. — The general form of the body is oval, the 

 dorsal surface is globose. The body is usually light-yellow to yellowish- 

 green in color. The dorsal aspect of the head is brown, tan, or yellowish 

 gray. The cephalic portions are spotted with small brown or black areas. 

 The head is provided with many setae which are usually the longest setae 

 found on the entire body. The tergum of the prothorax is rectangular 

 and about twice as wide as long. The dorsal shield is wanting and the 

 lateral and caudal surfaces are provided with setae which are about as 

 long as the segment. The mesothorax and metathorax are subequal in 

 length, but the metathorax is wider than the mesothorax. The lateral 

 margins of both of these segments are provided with a few short setae 

 which are not as long as the segment. The dorsal aspect of abdominal 

 segments one to eight are similar and strongly convex, with a very distinct 

 coria between the segments, and never densely setaceous but provided 

 with a few setae which are never as long as the segment bearing them. 

 The lateral margin of the dorsal aspect of the abdomen is provided with 

 a series of lobes between the annulets. These lobes are provided with a 

 few setae which are not as long as the segment. The sterna and the 

 lateral aspect of segments one to eight are provided with a few short 

 setae which are almost invisible. The tergum of the ninth abdominal seg- 

 ment is more or less shield-shaped, more than twice as wide as long, with 

 the caudal margin broadly rounded. The lateral and caudal margins 

 bear setae which are not as long as the segment. The ninth sternum is 

 about one-half as long as the tergum, its cephalic margin is broadly convex 

 while the caudal margin is deeply emarginate. The sternum and the 

 lateral aspects are provided with a few small setae. The tenth abdominal 

 segment is retracted into the ninth so that, as a rule, it is not visible. The 

 tenth segment is small, circular, and membraneous. The rectum is eva- 

 ginated to form a sucking disk. The legs are small, dark brown, and well 

 developed, but do not extend beyond the sides of the body.
