not projecting ; " and in his Ann. du G. de N. adopts Ehlers' 

 diagnosis of Procer^ea. Marion and Bobr. [Ann, des Sci. 

 Nat., Series vi, vol. 2) assign palpi to their Auiolytus {Pro- 

 cercea) ornatus. They regard Progeria as a subgenus of 



AUTOLYTUS. 



Finally, Marenzeller (zur Keniniss der adriatischen Ariel. 

 aus dem Ixxii Bande der Sitzb. der K. Akad. der Wissensch.) 

 states that Procercea pida Ehlers (type of the genus) has 

 palpi, as well as two species described by himself (P. luxu- 

 rians Mar., P. macrophthalma Mar.). He accordingly cor- 

 rects (1. c. p. 37) Ehlers' diagnosis of the genus, and adds 

 that the same is true for Autolytus. The following spe- 

 cies will be seen to bear out this conclusion. 



Autolytus hesperidum ClaparMe,

My specimens agree with A. hesperidum Clpd. in every 

 particular, save that they certainly possess projecting palpi. 

 These form a thin rim, projecting a variable distance 

 beyond the head, plainly divided below, separated above 

 only by a shallow depression. The head proper is trans- 

 versely oval, thicker and more convex than the projecting 

 part. The outline of head and palpi together is exactly 

 that given by ClaparMe. In the position of the central 

 antenna given in his figure, the line between the palpi is 

 of course concealed. This is often the case both in living 

 and in alcoholic specimens. In fact, I examined a number 

 of specimens without observing the palpi. When I did 

 see them, I supposed that my previous identification was 

 incorrect. It was, however, impossible to make a descrip- 

 tion, by which my specimens could be distinguished from 

 A. hesperidum. I had not at that time seen the observations 

 of M. and B., and of Marenzeller, cited above, by which 

 my views have been confirmed. I can not find that A. hespe-
