striated; the metathorax with a central longitudinal slight de- 
pression and obliquely striated, the striz diverging from the 
centre, its apex densely sericeous, and the pectus has a sericeous 
patch on each side beneath the wings; the tegule piceous; the 
wings clouded, with a dark border at their margin, their nervures 
black ; legs spinose, and the anterior tarsi ciliated. 
The abdomen has the petiole black as well as the extreme base 
of the first segment, the remainder of which, and the entire 
second, and base of the third, red ¢. 
The ¢$ differs in having the face beneath the antenne densely 
covered with a sericeous pubescence; the sculpture in general 
more strongly marked ; the metathoracic impression sometimes 
obsolete, with the petiole, and the superior surface of the two 
first segments, black ; sometimes the extreme base of the second 
red, and the rest entirely black.

abundant in the same district ; but that they are specifically 
different the most superficial examination will immediately 
detect, and until I have strong proofs to the contrary I shall 
hold Miscus a good genus.

head, geniculated merely at their extremity ; nearly all the joints 
of the palpi obconical.

Heap large, transverse, of the width of the thorax; eyes large,
