not projecting ; " and in his Ann. du G. de N. adopts Ehlers' 
diagnosis of Progeria. Marion and Bobr. [Ann. des Sci. 
Nal., Series vi, vol. 2) assign palpi to their Autolyius [Pro- 
cercea) ornatus. They regard Progeria as a subgenus of 
AUTOLYTUS. 
Finally, Marenzeller (zur Keniniss der adriatischen Anel. 
aus dem Ixxii Bande der Sitzb. der K. Akad. der Wissensch.) 
states that Procercea picta 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 specimeps 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 Clapar^de. 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 fin d that A. hespe-
