Thanks CD for suggestions for improving his descriptions of species by indicating localities. With few exceptions the Chalcidites of South America and Australia are remarkably like European species.
Chalcidites collected by CD are all similar to those of Europe. Mentions other specimens quite different from European forms.
Identifies two dipterous species of parasites [chalcidites].
Was not able to attend to the aphids last year, but will make use of CD’s suggestions and "study as much as I can the inquiry as to species".
Identified two flies as species of Empis that suck flowers, but the females also feed on small Diptera.
Identifies flies sent to him by CD. [CD note states that these were found with orchid pollinia adhering to them.]
The horns and spines of homopterous insects do not vary between sexes. Sexual differences in Blattidae.
