the median lobe and parameres of the aedeagus. They are thus 
evidently not conspecific. In S. striatipennis the basal three tarso- 
meres of the protarsus and basal two tarsomeres of the mesotarsus 
are dilated and bear tenent setae, while in S', laticollis the basal three 
tarsomeres of both legs are similarly modified. It should be noted 
that Portevin (1926) erred in describing this character for striati- 
pennis as well as in attributing a 5-5-5 tarsal formula to this species 
(tarsi are 5-5-4 segmented in S. striatipennis and S. laticollis). 
The genus Stetholiodes has been well characterized by Wheeler 
(1981), whose description is virtually unmodified by the addition of 
S. striatipennis. I would add that both Stetholiodes species lack an 
epistomal suture and have a supraocular carina and groove that 
separate the side of the head (including the eyes) from the dorsum. 
This last character is found in most or all Agathidium but is absent 
in Anisotoma and allied genera of Anisotomini. I agree with 
Wheeler that Stetholiodes is closely allied to, and possibly conge- 
neric with, Agathidium. At present Stetholiodes appears to differ 
from Agathidium only in having nine distinct punctate elytral striae, 
rather than fewer or no striae, and in lacking an epistomal suture. 
Further study of the large and diverse genus Agathidium is needed 
to clarify the status of Stetholiodes. 
I thank Mile. Nicole Berti of the Museum National d’Histoire 
Naturelle, Paris, for loan of the holotype of Agathidiodes striati- 
penne; and Fernando Angelini, Hermann Daffner, Stewart B. Peck 
and my wife, Margaret K. Thayer, for commenting on the manus- 
cript. Dr. Angelini has noted a recent collection of two males of S’. 
striatipennis from Aru, Kashmir, October 1977, leg. H. Franz, now 
in his collection and that of Dr. Franz.
