536 SUPPLEMENT. 
One example. Larger than D. pallida (=cucujiformis), the head much more finely 
punctured ; the thorax less constricted behind, and much more finely and sparsely 
punctured; the epistoma of the male much larger and angularly produced on either 
side in front (instead of truncate); the lateral processes in this sex stouter and more 
prominent, without an additional tooth beneath. Easily distinguishable from our other 
species by the quadrituberculate anterior margin of the head in the male sex. 
SITOPHAGUS (p. 160). 
Sitophagus cynzoides (p. 162). 
To the locality Mexico, add:—Ciudad in Durango (Hége), Mexico city, Las Vigas 
(fohr). 
This species was doubtfully included by me in Sitophagus ; it would be better placed 
in Mophis, the head being similarly formed in both sexes. S. cynwovdes closely 
resembles I. affinis, but is more elongate and more parallel; the thorax is more 
deeply emarginate in front, and the basal fovese are shallower. 
ULOSONIA (p. 163). 
Ulosonia bi-impressa (p. 165). 
To the localities given, add:—Mexico, Tehuantepec, Tapachula (Hége), Temax in 
North Yucatan (Gaumer). 
METULOSONIA (p. 166). 
Metulosonia reflexa (p. 166). 
To the localities given, add :—Mexico, Motzorongo in Vera Cruz (Flohr). 
MOPHIS (p. 168). 
This genus approaches very near Cynewus, but may be known from it by the broader 
epipleuree, the more prominent eyes (the sides of the front not extending so far 
outwards), and the differently formed antenne. 
Mophis affinis (p. 169). 
Mophis aterrimus, huj. op. p. 169. 
To the localities given, add:—Omilteme in Guerrero (H. H. Smith), Huitzo in 
Oaxaca (Hoge). 
The locality Las Vigas should be erased.
