502 SUPPLEMENT. 
Asida obovata (p. 63). | 
To the Mexican locality given, add :—Paso del Norte in Chihuahua (Hoge). 
Asida blapsoides (p. 63). 
To the Mexican localities given, add :—Zapotlan in Colima, Guadalajara, Toluca 
(Hége), Amecameca (Flohr), Volcan de Ixtaccihuatl 11,500 feet (Richardson). 
A very close ally of A. obovata and A. convera, Lec., but differing from both of them 
in the less reflexed margins of the thorax, the anterior angles of which are more obtuse. 
The coarsely punctured specimens referred by me to this species, of which we have 
received but few as yet, will probably have to be separated ; these include two forms— 
one with, the other without, a marginal carina to the elytra. 
Asida blanda (p. 63). 
To the Mexican locality given, add :—Aguas Calientes city, Lagos (Hoge). 
Distinct from A. blapsoides in all its varieties by the more thickened and reflexed 
lateral margins of the thorax; A. obovata has the thoracic margins more narrowly 
reflexed. 
Asida sphericollis (p. 64). 
To the Mexican locality given, add :—Aguas Calientes city (Hoge).
