269] THE LARVAE OF THE COCCINELLJDAE—GAGE 37 



are wanting; and its sternum is provided with ventral and ventro-lateral 

 chalazae. The tenth tergum is not visible from the dorsal aspect and the 

 greater part of its ventral aspect is hidden by the evaginated rectal disk. 

 The legs are long and slender, about one and one-half times as long as the 

 metathorax is wide. 



CocciNELLA Linne 

 The body is fusiform, elongate and widest at the metathorax. The 

 head is usually light-brown colored and provided with many setae. The 

 epicranial arms diverge immediately from the occipital foramen and be- 

 come obsolete near the antacoriae. The mouth is directed ventrad and 

 slightly cephalad. The thoracic segments are provided with a dorsal 

 shield. The dorsal and dorso-lateral aspects of abdominal segments one 

 to eight are provided with parascoli or verrucae, the ventro-lateral aspect 

 with verrucae, and the ventral aspect with verrucae or chalazae surrounded 

 by a few setae. The dorsum of the ninth abdominal segment is shield- 

 shaped and densely setaceous, the ventral aspect is provided with verrucae 

 or chalazae, and is about one-half as long as the dorsal aspect. The legs 

 are well developed, stout, and extend beyond the lateral margins of the 

 body. The coxacoriae are distant. The basal portion of the tarsal daw 

 is provided with a distinct appendiculate tooth. 



Species of Coccinella 



Terga one to eight with distinct parascoli; prothoracic shield with two 

 distinct, longitudinal, dark, heavily chitinized areas on each side of 

 the meson C. 9-notata 



Terga one to eight with strumae; prothoracic shield with a single, dark, 

 heavily chitinized area on each side of the meson C. sanguinea 



Coccinella 9-notata Herbst. — The body is fusiform, usually stout, and 

 widest at the metathorax. The dorsal and dorso-lateral surfaces are pro- 

 vided with parascoli, and the ventro-lateral surface with small verrucae. 

 The general color is light grayish-brown to dark tan or brown marked with 

 white or lemon-yellow areas. The dorsal portion of the head is light- 

 brown and the face is cream-colored. The epicranial arms diverge from 

 the occipital foramen and the mouth is directed slightly ventrad and 

 cephalad. The prothorax is wider than long and oval in outline; the dorsal 

 shield covers the greater part of its dorsal surface and bears four distinct, 

 dark-colored, longitudinal areas; and the cephalic, lateral, and part of the 

 caudal margins are provided with chalazae. The mesothorax and meta- 

 thorax are subequal in size, each is about twice as wide as long and each 

 dorsal surface is provided with a small oval dorsal shield on each side of the 

 meson. There is a small dorso-lateral parascolus on the caudo-lateral 

 portion of both the mesothorax and metathorax. Each thoracic sterna 

 is provided with a pair of verrucae which are adjacent to the ventro-meson.
