No. 2323. LARVAE OF THE GLERIDAE—BOVING AND GHAMPLAIN. 637 



PHYLLOBAENUS MEEKEtl Horn. 



Is a predator on barkbeetles, Jeffery pine infested with Ips, alliga- 

 tor juniper infested with PMoeoshms and reared from cypress. 

 New Mexico, Arizona, and California. Observations by Hopkins, 

 Webb, and Chrisman. 



Genus NEICHNEA Wolcott and Chapin {ELLIPOTOMA Spinola; 

 ICHNEA Castelnau). 



NEICHNEA LATICOKNIS Say. 



Is one of the principal enemies of the smaller 8colytoidea in the 

 east. Is a predator on Phloeosinus in Juniperus virginiana and 

 Taxodimn distichvm^ Ghramesus icorme, and sometimes Scolytus k- 

 sfinoms in hickory, Phloeofhthorus in Morus, Phloeo'phthorus in 

 Gercis canadensis^ Phloeotrihus in Celtis and many other Scolytoids 

 in various trees. 



The adults are active during the summer months, June to August. 

 They are diurnal and can be found running over or resting on in- 

 fested twigs or on foliage. 



The eggs are laid in or at the entrance gallery of host. The larvae 

 are to be found in the primary ^gg gallery of the Scolytoid. They 

 feed upon the dead parent adults, the eggs and first krvae of their 

 host. But one larva of the Clerid occurs in the primary egg gallery 

 of the Scolytoid. 



The Clerid larva when mature remains in the primary Qgg gallery 

 where it overwinters. It probably feeds to some extent on the mois- 

 ture, etc., in the gallery, but does not follow the larvae of host into 

 their mines, nor does it wander from the gallery. 



Prepupal larvae and first pupae may be found in the spring (May 

 26, at Westbury, Long Island, New York). Adults emerge in June. 

 In localities where two generations of the host occur it is very prob- 

 able that there will be two generations of the predator. 



The pupae occur bare in the primary Qgg gallery of the host. No 

 protective covering or whitish exudation observed. 



Distribution: Pennsylvania, New Jersey, Connecticut, West Vir- 

 ginia, Virginia, Florida, Maryland, North Carolina. 



Observations by Fiske, Hopkins, Craighead, Champlain.
