74 THE CANADIAN ENTOMOLOGIST. 



margin elevated ; disc irregularly punctate, a rather large fovea in front of 

 the scutellum. Scutellum yellow. Elytra distinctly scabrous, subopaque 

 to the naked eye, shining under a lens, finely sparsely pubescent ; costse 

 faintly indicated. Body beneath alutaceous, very finely scabrous, the 

 meso- and metathoracic regions rougher than the rest. Legs yellow, 

 knees, tips of tibiae and tarsi blackish. Length, lo to 12 mm. 



Eight specimens are before me, all taken at Pierre, South Dakota, by 

 the late P. C. Truman. The principal variation in markings consists of a 

 tendency to loss of the elytral stripe, although one strongly-developed 

 specimen, with the vitta well marked, has the suture dark for the greater 

 part of its length. The under surface of the body is always more or less 

 blackish, sometimes almost entirely so except the prothoracic region, which 

 remains yellow. In one case, the anterior tibise are blackish to base. By 

 the form of the head, this insect is allied to P. hitulata and P. Germari, 

 being close to the latter in several respects, but Dakotana has shorter and 

 thicker antenn?e. The style of ornamentation and the opacity of the 

 elytra will at once distinguish it from bilineata. The maxillary palpi are 

 not deformed in the male, the last joint being but slightly modified. 



MY LAST REPLY TO MAJOR CASEY. 



BY E. WASMANN, S. J., LUXEMBURG. 



In Dr. David Sharp's "Zoological Record, Insects," 1901, I find in 

 the list of my publications of that year, under the title, 1449, ''On some 

 genera of Staphylinidce described by Thos. L. Casey,'" the following note : 

 " Casey replies to this, I. c, pp. jj2, 313.'' 



As I do not receive American journals here, I tried to get the 

 respective nos. of the Canadian Entomologist from one of my friends. 

 Being informed now of the contents of Major Casey's " reply," I 

 understand why he did not send it to me, although I had sent him a copy 

 of my critic paper ''■On some genera of Staphylinidoi" already, Nov. 

 2nd, 1901. 



The manner in which Major Casey has treated our scientific 

 controversy differs far from my own in the article cited above 

 (Canad. Entom., Sept., 1901, p. 249-252). In an angry tone he 

 reproaches me of " disingenuousness," "narrow-mindedness," etc.; he 

 even tries to misinterpret my own personal correspondence with him 

 in a way (juite new in scientific discussion.
