I was much surprised when a few specimens of 
this species were located in the midst of a mass 
of Drosicha townsendi (Ckll.), and it seems very jo Jo is piat 
strange that it has not been collected again in Ma- —chasi Mask., adult 
nila, but the material at hand has produced no {"¥., rom 
other specimens of this species. Those found pores, x 640. 
were from Manila “on various trees” (coll. Compere), and were 
collected in 1911.
