352 : SUPPLEMENT. 
less developed (possibly the specimens are females); their first club-joint is triangular, 
the inner angle acute, the second club-joint is nearly of the same form, the third or 
terminal joint is oval, shorter than in P. brevis, and the appendages are red. Two 
specimens. 
LYCTUS (p. 211). 
By an oversight the Subfam. “ Lyctini” (including two species of Lyctus) has been 
placed after Polycaon plicatus on p. 211; it should precede the Subfam. “ Bostrychini” 
on p. 210. 
Lyctus prostomoides (p. 212). 
To the localities given, add :—Murxico, Guanajuato (Sallé); ?Nicaracua, Chontales 
(Janson). 
One specimen from San Lorenzo in the State of Panama has the head and thorax 
covered with thick brownish-grey pubescence, and the elytra evenly pubescent. 
A single example, in very bad condition, from Chontales is perhaps referable to this 
species. 
APATE (p. 212). 
Apate punctipennis (p. 213). 
Bostrichus migrator, Sharp, Scient. Trans. Royal Dublin Soc. iil. series 2, p. 160°. 
To the localities given, add:—Mexico, Northern Sonora (Morrison), Tres Marias 
Islands (Forrer), Esperanza, Jalapa, Almolonga (MHége); Nicaragua, Chontales (Belt, 
im coll. Sharp); Panama, 'Taboga Island (Champion). 
By the kind permission of Dr. Sharp I have examined specimens of the species from 
Honolulu’, described by him under the name of Sostrichus migrator, and I agree 
with him that no difference exists between them and a specimen in his collection 
from Nicaragua; it appears certain to me also that it is identical with the present 
species. I have also through Dr. Sharp’s kindness examined an authentic specimen 
of Amphicerus fortis from Arizona; this latter, though very closely allied, differs (as 
I had gathered from the description) from both this, which I still regard as A. puncti- 
pennis, Lec., and from another species in my own collection, notably by the shorter 
thorax having the hind angles produced into a sort of tubercle. 
Whether Bostrichus bicornutus, Latr., is the same species, I have no evidence for 
determining, the synonymy in the Munich Catalogue only referring to catalogue names 
with no kind of authenticity or value.
