the yellow transverse antemedian lateral patch on the elytra reduced to-a small spot, 
and in one of the San Gerénimo examples it is entirely obsolete. C. callosa, Boh., 
. from Texas, appears to be a very close ally of this species. | 
HYBOSA. 
Hybosa, Boheman, Monogr. Cassid. iii. p. 1 (1855). 
Kight species of this Tropical-American genus have been described, one only of which 
enters our region. Hyéosa is chiefly distinguished by the base of the prothorax being 
strongly bisinuate on either side, with a broadly produced obtuse median lobe.

_ The type in the Baly collection is a female; the male is rotundate, much less 
elongate. The four specimens before me from Central America include both sexes; 
the females agree perfectly with the type. 
CHARIDOTIS. 
Charidotis, Boheman, Monogr. Cassid. iti. p. 7 (1855) (part.). 
The species here referred to Charidotis agree in the following particulars :—Antenne 
short, not extending beyond the base of the prothorax ; joint 3 very short, much shorter 
than, and not nearly so stout as, 2; joints 4-6 each much longer than 3, 7-11 stout, 
8-10 not longer than broad. In the South-American C. miniata, placed by Boheman at 
the head of the genus, joints 4 and 5 are subequal, each twice as long as 3, the latter 
very short, and 6-11 are thickened. Boheman included various species under Coptocycla, 
such as C. fahrei, C. circumducta, C. zonata, &c., with an equally short third antennal 
joint; but these species have longer antenne, with the joints subfiliform or gradually 
thickening outwardly. Sixty species of Charidotis have been described, all Tropical- 
American, the genus ranging as far north as the Mexican State of Vera Cruz. Nine 
species only are known to me from within our limits, all of which appear to be very 
rare. As understood here, several species placed by Boheman under Charidotis belong 
to Coptocycla, e.g. C. circulifera &c.
