the antenne are slender and setaceous; the spurs of the posterior tibiz are equal, 
marrow and obtuse. The mouth and its organs are black ; the labrum moderately 
emarginate; the feet are black, the thighs rufous at base. Pallas, Icon. Ins. 
Ross. tab. E. f. 33, is cited by Olivier under this species, but the reference does 
not appear in my manuscript.

This species replaces the preceding in the Southern States; inform and struc- 
ture it is precisely similar; the antenne are a little shorter, the first joint and 
the base of the 2d and 3d are rufous; the labrum and palpi are rufous; the outer 
margin of the thighs, tibia and tarsi is black; the coxz are rufous; the two ex- 
ternal vitte of the elytra are confluent at the humerus.

Middle and Southern States. The outer joints of the antenne are closely ar- 
ticulated; the eyes are oval, very slightly emarginate, and not transverse, as in 
the species of the preceding division. ‘The spurs of the posterior tibiz in the 
species of this division are very slender and veryacute. ‘The vitta of the elytra 
is occasionally obsolete, and sometimes entirely wanting; in the latter case the 
pubescence of the thorax is more scanty, so that the specimens have entirely 
the appearance of small individuals of L. cinerea Lec. (Lytta marginata Fabr.)

form and stiucture to the preceding, and only differs in the pubescence being 
denser and uniform in color.

Two specimens; San Diego, California. Body black, thinly covered above 
and below with fine cinereous pubescence. Head rounded behind the eyes, 
which are oval, convex and scarcely emarginate; punctured, vertex witha small 
red spot, front with three faint impressions between the antenne; antenne 
shorter than the head and thorax, very slightly thicker externally, joints closely 
articulated, not at all rounded, 3d longer than the 4th. Thorax narrower than 
the head, somewhat bell-shaped, narrowed in front, rounded on the sides, disc 
punctured, middle of the base transversely impressed. Elytra more than twice 
as wide as the thorax, conVex, sides parallel; rugosely punctured, with a broad 
fulvous vitta, covering the whole humerus, and reaching the external margin at 
the base, contracted at one third the length of the elytra, then dilated again, and 
extending nearly to the tip, and including a lateral black spot at the posterior 
fourth ; this spot is connected with the black margin. Tarsi black, claws testa- 
ceous, with the inferior portion one third shorter than the superior. Spurs of the 
posterior tibia very fine and acute.
