Some lime ago, when about to publish a synopsis of the genus Scolops, the writer discovered that Dr. Uhler had the same genus in hand and his MSS. read for the press. As the result of the correspordence,the writer dropped his work for the time, and Dr. Uhler promised to send his types as soon as his paper was published. (Proc. Md. Acad. Sc., p. 401, 1900.) With his usual thoughtfulness, the Doctor sent on the types,and with the aid of these and a fine series of eastern forms received from Mr. Otto Heidemann the author has been able to definitely place all the described species and recognize a number of nerv ones.

The genus is found in its greatest abundance the border line of plain and mountain region, and so many rew forms have been found here in the past few years that there are no doubt many more to be found on further search.
