No. 2323. LARVAE OF THE CLERIDAE—BOVING AND CHAMPLAIN. 627 



In most instances the pupal cell of the host was utilized, but in 

 some cases they constructed pupal cells in the galleries or in the 

 wood. Pupae were found from December 1st until spring. The 

 majority overwinter in the pupal stage rather than that of mature 

 larvae, as do most of the Clerids studied. The pupal cell was 

 but slightly lined with the whitish exudation, but the loose particles 

 and frass at each end of the cell were' firmly sealed with it. 



In most cases the pupae rested vertically in the cell. 



The transformation from pupal to adult stage takes place in early 

 spring. The adults begin to emerge in June. 



The species occurs in Eastern and Central States, Southwest to 

 Texas. Observations by Champlain. 



Adults collected by Fiske beneath chips and dead bark of girdled 

 chestnut, Melrose, North Carolina, May 18, 1903 ; by Hopkins, Wood 

 County, West Virginia, May 15, 1891. 



CYMATODERA INORNATA Say. 



Is a predator on secondary woodborers. Reared from dead, dry 

 limbs of hickory infested by Bostrychus hicornus; from dead stand- 

 ing birch infested by Melasis and Buprestid larvae; also reared 

 from oak, hackberry, and beech. 



Adults fly during June and July in Pennsylvania. 



Occurs in Eastern and Central United States. 



Observations by Hopkins, Craighead, Van Horn, Champlain. 



CYMATODERA MOROSA LcConte. 



Is a predator in larval stage on Geramhycid and Buprestid borerb 

 infesting scrub oak in Colorado. Found feeding on Ghrysohothris 

 larvae beneath bark and larvae of Brothylus geminatus in the base 

 and roots. The life history as far as noted is very similar to C. 

 hicolor, except that pupae were not observed until spring. Observa- 

 tions by Champlain, at elevations ranging from 6,000 to 7,000 feet in 

 Colorado. 



CYMATODERA UNDULATA Say. 



Is a predator on wood; stem and twig borers. Reared from 

 chestnut infested by Oallidium aereum; maple infested by Eucne- 

 mids; Populus deltoides infe'sted by Oherea; oak infested by Elaphi- 

 dion; also from sumac, wild grape, hackberry, birch, butternut, 

 Celastrus scandens and Ampelopsis quinquefolia. 



Adults fly during July, August, and September. Occurs in 

 Eastern and Central United States. Observations by Hopkins, 

 Kirk, Fiske, Craighead, Webb, Van Horn. 



CYMATODERA BALTEATA LeConte. 



Adults reared from dying wild grape infested by Clytoleptus 

 albofasciatus in Pennsylvania; also reared from hickory and hack-
