Discussion: The lectotype of Desmoris montanus Dietz is evi- 
dently either teneral or lighter (in color) than the average specimen 
of S. sordidus LeConte. There is some individual variation in size 
and color in S. sordidus, and it is not difficult to find some specimens 
which are as large as the lectotype of D. montanus and more reddish 
brown than piceous. 
In the past, many authors have applied the name Desmoris con- 
strictus (Say) to the species which LeConte (1876) named Smicronyz 
sordidus. Upon examination of Say’s description (1823) of Desmoris 
(then Rhynchaenus) constrictus, and a specimen (now the neotype) 
determined by Say as Rhynchaenus constrictus, it is evident that Say 
applied that name to a different species than the one described by 
LeConte as Smicronyx sordidus in 1876. <A full discussion of the 
differences between the two species is given with the discussion of the 
neotype of Smicronyx (Desmoris) constrictus (Say). 
Distrisution: S. sordidus is one of the most wide-ranging Smi- 
cronyxz species in North America. Existing records indicate the pres- 
ence of this species in parts of all the major regions west of the Atlantic 
coastal plain, including the interior plains region, the Gulf coastal 
plain, the southern Rocky Mountains, the basin and range province, 
and the Pacific mountain system. The following specimens were
