Megacyllene antennata (White) . New larval host

record.

RLA collected teneral adults, pupae, and prepupal larvae in December in a large broken branch of Celtis reticulata Torr. from AZ: Gila Co., Rye.

Microclytus gazellula (Haldeman) .

According to Craighead (1923), this species develops in the outer bark of living Quercus and overwinters as an adult. JV found one adult in a pupal cell in the outer bark of mature, living Q. alba

in October from PA: Montgomery Co., Green Lane. Two adults were found in pupal cells from PA: Luzerne Co., along Nescopeck Creek, one in May and one in September. In all cases, the trees were also inhabited by Encyclops caerulea (Say) , which is common in eastern Pennsylvania and can be found in more or less all mature Q. alba trees. The galleries of M. gazellula were noticeably smaller and more tightly packed with fine frass compared to those of E. caerulea , which are loosely packed. They seem to prefer mature trees with thick bark, which are rather scarce in the eastern USA due to significant logging in the past.
