263] THE LARVAE OF THE COCCINELLIDAE—GAGE 31 



COCCINELLTNAE 



The body is elongate to oval, dorsal surface convex, ventral surface 

 concave or flat. The body-wall is provided with senti, strumae, verrucae, 

 chalazae, or evenly distributed setae. The head is provided with long 

 distinct setae. The epicranial stem and epicranial arms may be present 

 or wanting, when present, the epicranial stem never extends more than 

 one-third of the distance from the occipital foramen to a line drawn through 

 the antacoriae. The clypeal suture is never entire, but is usually indicated 

 by a distinct furrow which extends mesad on each side from the precoila. 

 The antennae are never more than three times as long as wide, consist 

 of three segments, and are inserted about midway between the ocelli and 

 the precoilae. The mandibles usually have one, two, or three teeth at the 

 distal end, and the proximo-mesal margin is provided with a triangular or 

 mound-shaped mola. 



This subfamily includes all of those tribes the members of which are 

 carnivorous. They may also be phytophagous to the extent that they 

 may eat fungi and probably small amounts of pollen. 



Tribes of Coccinellinae 



1(6) Epicranial arms always present; epicranial stem always present 

 in all larval stages unless obliterated by the separation of the 

 epicranial arms 2 



2(3) The dorsum of the body armed with senti six to eight times as long 

 as wide; the epicranial stem extending one-third of the distance 

 from the occipital foramen to a line drawn through the antacor- 

 iae; epicranial arms gradually divergent Chilocorini 



3(2) The dorsum of the body never armed with senti six to eight times 

 as long as wide 4 



4(5) Dorsum of the body armed with short senti, parascoli, or strumae; 

 epicranial stem, when present, never extending one-third the 

 distance from the occipital foramen to a line drawn through the 

 antacoriae; epicranial arms gradually or abruptly divergent 

 Coccinellini 



5(4) Dorsum of the body provided with small verrucae or setae; epi- 

 cranial stem always obliterated by the separation of the epicra- 

 nial arms, epicranial arms diverge from the occipital foramen 

 Microiveiseini 



6(1) Epicranial stem and epicranial arms never present in adult larvae 7 



7(8) The dorsal and lateral aspects of the body with strumae or 

 verrucae Scymnini 



8(7) The dorsal and lateral aspects of the body with fine slender setae 

 Hyperaspini
