After having been. colonized for ‘three years in the Jenanese Beetle area,

ered at the Moors mote? (ees pile colony center. This is the third imported 
parasite of the Japan e beetle to have. ~peen, recayered, the other two being 
the. tachinid Centeter Sh vaich destroy rs the vestles, ‘and the scoliid Tiphia 
popilliavora, attacking the grub stage... 
Shipments of Dexia ventralis, a Korean fly attacking a number of scarabaeic¢ 
larvae, and a Tiphia attacking Anomala, were recently. sent from the station at

the territory infested with the orient al Anomala’ and Aserica. 
‘In the present season the colonizations. of Prosena siberita, Ochromeigeni: 
“ormioides, Tiphia vernali ;, and the so-called "Japanese red-leggzed" Tiphia have 
been much eae and, more satisfactory than in former years. This achievement 
has been due in. ge measure to the excellence of the ‘shipments from Japan, 
and to. the ae improvement in the technique of handling at the receiving
