ing exterminated them. Mr. Cook, however, said that the mon 

 goose was still scarce on Porto Rico. Mr. Ashmead suggested 

 that the Spiroboli might climb the trees to get away from their 

 natural enemies, such as Pyrophorus. 



The second paper was by Professor Kincaid, and was enti 

 tled " Notes from Alaska." He spoke of his trip in 1897 on the 

 Fur Seal Expedition, giving general remarks as to the forms col 

 lected. At Sitka he found several sawflies and a Psychoda previ 

 ously described from Vancouver and Seattle. At Unalaska he 

 found a rich collecting field, where, if the whole season were 

 covered, good finds would result. He found there Tenthredo 

 nigrofasciata, a form described in 1822, which he takes to be a 

 Macrophya. On the Pribiloff Islands he found several species of 

 beetles. Carabidag and Curculionidae were found under logs. In 

 the tundra, or very deep moss, he found some interesting species 

 by digging up the moss and shaking it over cloths. In digging 

 post holes beetles fell into the holes from the tundra, and inter 

 esting forms were collected in this way. Among the Diptera, 

 Muscidae were very abundant. Syrphidae, however, were rare, 

 although there were many flowering plants. There were some 

 Borboridas which were of importance in fertilizing flowers, espe 

 cially the Gentians. Among the Hymenoptera, Bombus kin- 

 caidi Ckll. was the most prominent, but there were numerous Ich- 

 neumonidae and Chalcididae, and one newsawfly. He noticed nu 

 merous galls on willows, indicating the occurrence of gall-making 

 sawflies. There w;ere very few Lepidoptera, and no butterflies 

 among them. The forms consisted of an Arctian, a Noctuid and a 

 few micros. A few spiders were found, but no orb weavers. 

 There were two Myriapods and eight or ten species of Thysa- 

 nura but only two Hemiptera, the one a Capsid and the other an 

 Aphid. In his trip made in 1899 with the Harriman Expedition 

 he found it interesting to compare the Pribilofts with the Popof 

 Island, where he collected rather thoroughly. In the latter 

 place there were very few beetles. The absence of beetles he 

 accounted for on the ground of the abundance of rodents. He 

 found two butterflies. The absence of strong flying insects he 

 accounted for by the prevalence of very severe winds. The flight 

 of one of the butterflies had been very peculiarly modified, as he 

 thought, by the strong winds. It could hardly be induced to fly,
