For most of the material from which the following new
species of Cicadidae are described, I have to thank Mr. F. P.
Dodd (queensland) and Mr. H. Elgner, of the same State.
Amongst them it will be noticed is a new species of Cyclochila
from Queensland, and also a species of Prasia, a genus so far
unrecorded in Australia, though common in New Guinea. I
have had some difficulty in deciding upon the generic deter-
mination of Psaltoda pulchra, as it has strong affinities with
Thopha in the structure of the head and the proportions of the
tegmina and wings. The abdomen, however, is unadorned with
the sacs which hide the tympana in the division Thopharia,
so I have placed the species tentatively in the genus Psaltoda.

The fourth in a series of online collections from Harvard University, Expeditions and Discoveries delivers maps, photographs, and published materials, as well as field notes, letters, and a unique range of manuscript materials on selected expeditions between 1626 and 1953. The collection is made possible with the generous support of the Arcadia Fund . In the 19th and 20th centuries, Harvard University played a significant role—as underwriter, participant, collector, and repository—for pace-setting expeditions around the world. For Internet users, Expeditions and Discoveries provides selective access to Harvard’s multidisciplinary records of those expeditions.
