Hind angles of thorax very broadly rounded ; fourth joint of antennae prolonged 

 in a process, fully half as long as the following joint Staff, Schauf. 



With the exception of Ulkei, which is from Utah, all the species are 

 from California. The females of three are known tome. In the more 

 extensive paper which I have prepared fuller descriptions will be given 

 together with such figures of details as may be needed to arrive at a cor- 

 rect understanding of the systematic position of Pleocoma. 



WILLIAM W. HILL. 



At Elizabethtown, Essex County, N. Y. , on January 28th, 1888, 

 died William W. Hill of Albany, N. Y. This news will sadden all who 

 in any way have known Mr. Hill during his life lime, and among Ento- 

 mologists there are few who do not know him or his work. 



Mr. Hill was born September 19th, 1833, at Pittsfield, Mass., but 

 removed to Albany early in life, and entered the business house of Na- 

 thaniel Wright, dealer in saddler's hardware, at the age of fifteen. At the 

 age of twenty he became a partner in the firm of Nathaniel Wright & Co., 

 and on the death of the senior member of the firm the business was con-

 part of each Summer in the North Woods or in the Adirondacks — com- 

 bining this sport with his study of nature. 



For many years he was more especially interested in Botany and 

 made large collections of plants. In 1875 he became more especially 

 interested in Insects, and collected persistently, carefully and systematic- 

 ally — with what success all Lepidopterists know. Though more partic- 

 ularly a Lepidopterist he collected also in other orders, to obtain a re- 

 presentation of local species. With Messrs. Bailey, Eintner and Meske 

 he made excursions in the vicinity of Albany and finally Centre was hit 

 upon, as an extraordinarily productive locality and here collecting was 

 carried on with such vim and persistency that the place became known 

 as "Butterfly station." Enormous quantities of "sugar" were prepared 

 and used, and thousands of moths paid the penalty. During his visits 

 to the Adirondacks Mr. Hill not only sugared persistently, but every
