presented a couspicuous appearance. The male was tested for scent 

 with no perceptible result. A single specimen of Catophaga ega Boisd., 

 ^ fell to the net, but no corresponding male was seen. Small 

 yellow butterflies of the genus Terias abounded in the undei'growth. 

 These belonged to two distinct groups or sections, T. lineata Misk.. 

 the predominant form, being a member of the assemblage represented 

 by T. laeta, Boisd., while the other species present was the widely 

 distributed T. hecabe Linn. Fresh specimens of the latter appeared to 

 be generally of the dry- season form, but the wet and intermediate 

 phases were also to be met with. A. male T. lineata yielded a faint 

 flowery odour in scrapings of the scent glands ; in two males of T. 

 hecabe a slight but distinct flowery perfume was detected. In one of 

 these, a dry-season male, the " dog's head" was feebly developed. The 

 delicate-looking dragonfly, Neurothemis stigmatizans Fabr., ,^ , and an 

 unnamed Hemipteron near Biptorhis fuscus Fabr. completed the 

 catch on Magnetic Island, from which place we returned in the evening 

 to Townsville, across a sea which the sailors themselves acknowledged 

 to be exceptionally rough. 



We had expected to clear from Townsville on the evening of 

 September 7th, but were detained by order of the Naval authorities. 

 At 3 a.m. on the 8tli we were told to dismantle our wireless apparatus 

 and stay where we were until further notice. We were kept in un- 

 certainty about sailing all day long, but I found it possible to go 

 ashiire for an hour or two in the afternoon and to do a little collecting 

 in a steep and stony gully north of Townsville. The President of the 

 British Association and Mrs. Bateson, who also landed, drew my 

 attention to a tree where Tirumala hamata and Chanapa corinna were 

 going to roost in extraordinary numbers. C. corinna has usually 

 seemed to me to be odourless in both sexes, but on this occasion a cap- 

 tured male appeared to emit a snuffy odour, which was, however, very 

 slight. Mr. Bateson found a spider engaged in devouring a male T 

 hamata ; both these specimens he gave to me. A male example of 

 Precis albicincta Butl. was captured, which had on the underside the 

 whole of the posterior border of the hind- wing, and the greater part of 

 that of the fore-wing, sheared oft" as if by a straight cut from a 

 moderately sharp instrument. 



At midnight the embargo on our voyage was removed, and by 

 9 a.m. on September 9th we had started. Passing during the day some 

 fine bits of rocky, forest-clad coast, we arrived late at night at Cairns. 

 Next morning (September 10th) a party of us landed and proceeded
