6 Mr. J. 8. Baly on new Species of Cassidide. 
II.— Descriptions of new Species of Cassidide, together with a List 
of all the Species belonging to the same Family collected by the late 
M. Mouhot tn Siam and Cambodia. By Josern 8. Baty. 
Tur insects described in the following paper are principally those 
sent to this country by M. Mouhot; added to them are a few others 
lately received by me from other parts of the world. With regard 
to the List of Species, I have undertaken, in accordance with the 
wishes of Mr. Saunders, to draw up a catalogue of the Phytophagous 
insects collected by the late M. Mouhot, a set of the species having 
been ceded to me for that purpose. I propose taking each family 
separately, publishing them from time to time in this Journal as 
opportunities for their study arise. I have taken the Cassididee first, 
Professor Boheman’s recent supplement having brought our know- 
ledge of that group up to the present time. All the species contained 
in M. Mouhot’s early collections were sent by me to Boheman for 
determination ; and one, Coptocycla plausibilis, was described by him 
as new. The new species in the present paper arrived too late for 
insertion in his work. 
Spheropalpus Deyroller.

antennis, thoracis plaga dorsali, a basi fere ad apicem extensa, scu- 
tello, mesocoxarum plaga, geniculis, tibiarum apice, tarsis, metasterni 
macula triangulari parva, elytrisque nigris; his crebre subrugoso-punc- 
tatis, punctis prope suturam subseriatim, disco vage dispositis, utroque 
disco interiore obsolete bicarinato ; margine basali anguste obsoleto,

Hab. Brazil. 
Oblong-ovate, moderately convex, flavous, subnitidous, shining be- 
neath. Thorax rather more than twice as broad as long; sides broadly 
rotundate-ampliate, slightly narrowed at the base, the anterior angles 
armed with a very small obtuse tooth ; upper surface remotely but deeply 
and irregularly pitted, middle of disk longitudinally grooved, sides very 
deeply impressed, rugose-punctate, dilated margin reflexed, rather less 
closely punctured than the sides of the disk; on the disk is a large 
black longitudinal patch, which extends from the base nearly to the 
apex of the thorax. Scutellum forming an elongated triangle, the apex 
obtuse, its surface smooth, impressed near the apex with a single fovea. 
Elytra punctured as in S. e:nctus, sides obliquely dilated from the base 
to the middle, then obliquely narrowed and slightly rounded to the 
apex ; the latter narrow, obtuse. 
For the possession of this beautiful insect (which is probably a
