and in one from Frontera, Mexico, the two external black vitte of the elytra 
are confluent, or, at most, separated by a fine line of light pubescence. The 
thorax is elongate, transversely depressed before the apex, and parallel at the sides 
behind. The anterior tibiz have two spurs in the male. The labrum is rather 
deeply emarginate.

Dugés* describes an Hpicauta from the Sierra de San Luis Potosi, Mexico, under 
the name of £. vittata (Fabr.); but, from the description, I have no doubt that his 
insect is really referable to the closely-allied EH. lemniscata. Both Leconte? and 
Horn? state that E. lemniscata replaces E. vittata in the Southern States. I have not 
seen a specimen of either from within our limits. According to Dr. Horn?, E. vittata 
is abundant in early summer on potato and tomato-plants in the Middle States.

Not uncommon in Chiriqui. Allied to £. vittata, but smaller and narrower; the 
thorax black ; the elytra with the shoulder, the lateral margin, a slender median vitta 
nearly or quite reaching the apex, and sometimes a narrower abbreviated vitta within 
the margin, luteous, the suture, at most, very narrowly luteous; the underside and 
legs black, the coxe and the extreme base of the femora reddish-testaceous. The 
thorax is long and narrow, parallel at the sides behind. The eyes are very large and 
deeply emarginate; the spurs of the hind tibie are slender and subequal; and the 
anterior tibiz are bicalcarate in the male. In E£. vittata and E. lemniscata the suture 
is rather broadly luteous, the black stripe on either side of it does not extend so near 
to the base, and the humeri (as in £. vitticollis) are not entirely luteous. |

Elongate, opaque, very finely and closely punctured, finely pubescent; the head reddish-testaceous, with two 
spots of variable size on the vertex, the mouth-parts, and eyes black, the pubescence yellowish; the

black, with the lateral margin, the apex, and a narrow median vitta—widening a little in front and
