The fulvous markings both of the thorax and of the elytra apparently vary greatly 
in this species. I have only given the principal forms of coloration above, but inter-. 
mediate grades exist. M. rubrolineata is very closely allied to J. xerene, Newman, 
but may be known by its smaller size and narrower and more conical. thorax ; the 
serratures also on the outer margin of the elytra are nearly obsolete in the latter 
species. 
++ Interocular space distinctly produced ; four upper joints of the antennae 
consolidated into a single piece. 
UROPLATA. 
Uroplaia, Guérin, Icon. du Régne Ann. iii. Texte, p. 274; Baly, Ann. & Mag. Nat. Hist. 3rd 
ser. xiv. p. 335 (1864). 
Uroplata is closely allied to Chalepus, being only separated from that genus by the 
soldering together of the four upper joints of the antenne.. As a rule the insects: 
belonging to the two genera can be readily separated; but in certain- species of 
Chalepus (morio and its allies) several of the upper joints are so closely articulated 
with each other, and at the same time so densely clothed with adpressed hairs, that it 
requires a close examination to ascertain whether they are distinct or consolidated 
w th each other. 
Uroplata, taken as a whole, is more heterogeneous than Chalepus in the form both 
of its antenne and of its elytra; it probably, next to the latter genus, is also more 
numerous in species than any other (with perhaps the exception of Hispa proper) in 
the family. | 
‘The species are found in Central and South America; none, so far as my knowledge 
extends, occurring in the United States or in any other part of North America; the 
insects placed by Von Harold in his Catalogue as inhabiting the northern continent 
belong to the genus Chalepus.
