LARVAL FORMS OF COLEOPTERA 



often with numerous fan-sliaped, spinulose, or otherwise un- 

 commonly formed, small hairs; juxta-cardo present) 29 



Mandible without large, inultituberculate or multiearinate 

 molar structure 31 



29. Body choloniform, similar to body of a scale insect; along the 



sides with flat projections carrying spinulose setae. (Head 

 not visible from above; distal end of maxillary mala provided 

 with a brush of long, club-shaped hairs) 



Miirmediidoe'^^ (pi. 27 I-L) 

 Body different. (Maxillary mala with or without a terminal 

 brush) 30 



30. Distal end of maxillary mala with a brush consisting of a few, 



about four, long, stiff, curved and pointed setae; mandible 



Avith distinct apical part Endomi/chidae - Mijcetaeinae^^ 



(PL 39 A-G) 

 Distal end of maxillary mala with a differently shaped, often 

 large brush, or without a brush, or with a brush with few 

 setae but then with a mandible without apical part. 



Endom ijch idae-Endom ychinae*^ 

 (pis. 39 H-V, and 40 A-T) 



31. Mandible with reduced, smooth, and usually condyliform 



molar (mola like?) structure; distinct hypopharyngeal 

 sclerome present. (With or without cardo ; juxtacardo ab- 

 sent; with or without lacinia mandibulae ; three ocelli pres- 

 ent on each side of head, except in the blind termitophilous 

 larva of Orfalistes ruhidus Gorham, from Barro Colorado 

 island. Canal Zone, Panama) 



C occinellidae-C occinellinae (pis. 

 37 H-L and 38 A-I) 

 *® The larva of the different endomychid genera are remarkably 

 distinct from each other, strongly emphasizing the compound char- 

 acter of the family. On the other hand, the family is closely linked 

 both with the Lathridiidae and the Murmediidae, notably through 

 the endomychid Rhymhus. The larva of this genus occupies a re- 

 markable central position, approaching the specialized larvae of 

 the major part of the lathridiid genera in the unique development 

 of their mandibles, the primitive larva of the lathridiid genus 

 EufalUa in having an almost separate lacinia and galea, and the 

 Murmidiidae in the possession of tufted pleural projections. 

 Through this larva the Endomychidae and all of the families which 

 are closely or more remotely related to them may be traced to 

 primitive ancestors, in reality to near the leptinid association of 

 the Staphylinoidea. 



The larva of the Sphindidae, interpolated here before the 

 endomychid association, represents unquestionably a simple, primi- 

 tive eucujoid type, but its more precise systematic position is 

 rather uncertain. (Compare pp. 109 and 110 in the paper by 

 Peyerimhott', quoted in footnote number 46).
