Scpt.-Dec, 1920.1 Barber and Ellis: The Family Cupedid.e. 201 



life-history and the bionomics of the species herein concerned is more 

 ample it seems correct to place the CupedidiE in the Polyphaga, in the 

 position Kolbe has suggested for its retention. 



Immature Stages. 



Snyder (27) has recently pul)li.shcd descriptions and fifjurcs of 

 the larva? and pupae of Ciipcs concolor and has thereby filled a long 

 felt need. 



The larv?e were found excavating longitudinal burrows in solid, 

 but decaying chestnut (telegraph pole) and oak (trestle timbers). 

 The following is Mr. Snyder's cliaractcrization of the larva; and 

 pupse of Cupcs concolor Westw. 



" The lar\ a is 23.5 mm. in length, white, elongate and subcylindrical. 

 Body gradually broadening from the sixth to the eighth abdominal segment, 

 ninth abdominal segment conical, with numerous long hairs on sides, armed 

 with more heavily chitinized sharp tubercles, being produced to a narrow, 

 heavily chitinized cylindrical anal process; anal process widening at apex, tip 

 concave. Pleural ridge on all abdominal segments. Prothorax prominent, 

 approaching the characteristic dilation of Eiipsalis and Lymexilonid larvae, 

 broader than head and other thoracic segments. Prosternum broad, flat, armed 

 with numerous chitinized asperities. Legs 5-jointed, excluding claw; first 

 joint large, flattened, fleshy lobe. Labium with hairs on anterior portion. 

 Antennae 4-jointed. Maxillae with all three parts distinct; lacinia thick and 

 fleshy, with long hairs pointing inward on anterior portion, palpi 3-jointed ; 

 galea 2-jointed. Labium black, chitinous, chisel-edged emarginate, with 

 2-jointed palpi. Mandible lilack, chitinous with largo, blunt basal tooth and 

 3 other teeth. 



"Pupa is 11.5 mm. in length, white, body somewhat flattened, abdominal 

 segments gradually broadening : anal segment widest, conical ; genitalia with 

 2 lateral, curved, chitinous hooks, pointing anteriorly. Dorsal carina running 

 the whole length of the body, becoming more distinct toward the end of the 

 abdomen. -Antenna; lying ventrally, overlapping the elytra. Head bent ven- 

 trally at right angles to prothorax. First pair of legs lying between other 

 pairs."
