in its northern parts was evidently very great, so that the study of Siberian 

 species became essential, especially that part of Siberia extending from Lake 

 Baikal and the Altai Mts. eastward to the Paciiic, of which the fauna was 

 closely allied to ours. 



His remarks were discussed by Dr. Lutz and Dr. Bequaert, the latter say- 

 ing that the new method of fixing limits was very interesting and in northern 

 Africa its results were corroborated by those of botanists, based upon the dis- 

 tribution of Acacia. However, he thought it difficult to agree about Arabia 

 and the Sahara, the latter having possibly been at one time less arid than at 

 present. 



Mr. Leng mentioned the work of Poppius on the genus Cryobiiis as sup- 

 plying evidence of the strong relation between Siberian and Hudsonian 

 beetles. 



Mr. Dow spoke of the great interest attached to John Abbot's plates and 

 their superiority to the reproductions, also of the price he was paid for his 

 work by John Francillon, viz.: 6^ cents for each figure. 



Dr. Lutz spoke of Westwood's original drawings presented by Mr. Hyde 

 to the Museum. 



Mr. Watson read a paper on " A Large Number of Species of Butter- 

 flies observed in One Day's Collecting," which will be printed elsewhere. 



Mr. Notman exhibited and distributed specimens of Protheca pubcritla, 

 a Ptinid beetle, of which he had bred more than 100 from rotten wood at 

 Keene Valley, N. Y. 



Meeting of March 5. 



A regular meeting of the New York Entomological Society was held at 

 8:00 P. M., March 5, 1918, in the American Museum of Natural History, 

 President Lewis B. Woodrutf in the chair, with 22 members and two visitors, 

 Messrs. F. G. Carnochan and J. Tee Van, present. 



The Secretary read a letter from War Savings Society Bureau and ex- 

 hibited enclosures accompanying same. 



Mr. Engelhardt spoke of " Collecting in the Plateau Region of South- 

 western Utah," illustrating his remarks by a large number of photographs 

 and specimens of the Lepidoptera mounted by his companion, Mr. Jacob 

 Doll. Mr. Engelhardt said in part that their headquarters from about April 

 19 to July 22 were at Gregerson's Ranch, Bellevue, Iron Co., Utah, from 

 whence many excursions were made into the surrounding mountains, which 

 in beauty of rugged sculpture and coloring, were among the most remarkable 

 natural features of the continent. Bellevue is midway between Parowan and 

 St. George, Utah, where H. F. Wickham collected, but the great differences 

 of elevation in southwest Utah, ranging from 3,000 ft. in the Virgin River 

 Valley to 10,000/12,000 ft. on the plateaus, cause great faunal differences, and 

 his efforts were largely devoted to the more elevated sections, hitherto unex- 

 plored by entomologists. A full account of the expedition, with a map, is 

 given in the January number of the Brooklyn Museum Quarterly. The in-
