Deloyala pallida, Sturm, in litt.’ 
Hab. Muxtco2—5(Chevrolat?; Sallé, ex coll. Sturm), Cordova ( Sallé), Cuernavaca (Hége). 
I have seen four specimens of this insect, including one, no doubt the type, from. the 
Chevrolat collection in the British Museum. P. separata only differs from P. vitticollis 
in having much fewer punctures on the disc of the elytra, these being widely separate 
one from another.

Physonota bicolor, Sturm, in litt. 
Hab. Mexico 1-3 (Sallé, ex coll. Sturm), Oaxaca (Hége). 
There are two examples of this peculiar species in the Sallé collection, without 
nearer indication of locality. The type from the Stockholm Museum is figured. A 
rather narrow, oval species, with coarse, subserially arranged punctures on the elytra, 
the margins also coarsely punctured. The single specimen from Oaxaca is much 
smaller than the type, and has the dorsum of the elytra pitchy-brown, probably from 
discoloration. 
14. Physonota mexicana. (Tab. VIII. fig. 21.) 
Physonota mexicana, Boh. Monogr. Cassid. ii. p. 206", and iv. p. 249°; Cat. Col. Ins. Brit. Mus. 
ix. p. 100°. 
Hab. Mexico !~%, Guanajuato (Sallé), ‘Tula and Pachuca in Hidalgo (Hége). 
Sent in plenty by Hoge from the State of Hidalgo. P. mexicana is closely allied to _ 
P. ovata, Boh., but may easily be known from it by the blackish arcuate or >-shaped — 
mark on either side of the disc of the prothorax near the base, midway between which 
is a short oblong streak ; the elytra are rather coarsely, irregularly, seriate punctate, 
the margins also coarsely punctured. 
15. Physonota flavago. (Tab. VIII. fig. 22.) 
Physonota flavago, Boh. Monogr. Cassid. 11. p. 210’, and iv. p. 249%; Cat. Col. Ins. Brit. Mus. ix.

Hab. Mexico !~, Ciudad in Durango 8100 feet (Forrer). 
We figure the type from the Stockholm Museum. Very closely allied to P. picti- 
collis, Boh., but differing from it in the immaculate prothorax, and in having the 
elytra more coarsely and more closely punctured. ‘The two specimens (¢ ¢ ) received
