the fore-wing as well as to the entire hind-wing, thus involving 
just so much of the wings as was exposed during rest. He 
considered that the present series of specimens tended to 
illustrate and confirm Professor Poulton’s view of the generally 
cryptic character of ‘‘ dry-season ” phases. 
Professor E. B. Poutroy, F.R.S., read a paper entitled 
‘Notes upon some remarkable parasitic insects from North 
Queensland” by F, P. Dopp, F.E.S., and exhibited the fine and 
carefully labelled material sent by the author. This material 
consisted of a series of Lraconide bred from Lepidopterous 
hosts, Chalcidide from Lepidopterous and Hymenopterous 
hosts, and a new Cyrtid fly of the genus Ogcodes, bred from 
the Attid spider, Cosmophasis bitaeniata, Keys. The accurate 
observations upon these parasitic species render the paper of 
much value. Thus the host of the extraordinary and beautiful 
Chaleidid genus Schizaspidea of Westwood has never before 
been observed; but Mr. Dodd records that the specimen 
obtained by him—an example of a new species—was bred from 
the pupa of a large ant of the genus Camponotus. Professor 
Poulton desired to express his warm thanks for the kind and 
cordial help he had received from distinguished naturalists, 
in naming and describing the material, communicated to 
him by Mr. Dodd. In an Appendix to the paper the new 
forms of Braconidxe and Chalcidide were described by Colonel 
C. T. Bingham, and the new Cyrtid fly by Dr. Benno Wandol- 
leck of Dresden. The ants had been kindly named by 
Professor Auguste Forel of Morges, and the Attid spider by 
Dr. G. W. Peckham of Milwaukee. 
Dr. G. B. LonesrarF read a paper “On some Rest Attitudes 
in Butterflies,” illustrated by numerous specimens arranged 
upon backgrounds of specially-prepared sand-paper approxi- 
mating to the natural surroundings of the insects in their 
various habitats. 
Dr. T. A. CHapMAN understood that Dr. Longstaff’s remarks 
referred chiefly to resting attitudes during quiescence, when 
invisibility was desired, but the heliotropic attitude with tail 
to the sun, was familiar to observers of Vanessas and other 
Nymphalids—and some other butterflies of the European 
fauna. During their active period, when, settling, usually on
