in Canada by Dr. Bigsby. 
Body long and narrow, black, underneath slightly and minutely punc- 
tured, with the sides of the breast and abdomen brilliant with a silvery 
lustre from decumbent silky hairs, above glossy and almost naked. Head 
thickly punctured, but behind each eye there is a levigated space ; 
antennæ longer than the prothorax, intermediate joints not slenderer 
than the others, the fourth as long as the fifth ; neck short and levigated: 
prothorax bell-shaped, not constricted anteriorly, depressed posteriorly ; 
thinly punctured, especially in the disk: scutellum triangular: elytra 
punctured but not thickly, punctures almost arranged in rows, towards 
the apex they are very slight ; a reddish-yellow subflexuose stripe runs 
from the middle of the base of the elytra a little more than half way 
towards the apex, which is diverging and truncated: the ventral segments 
of the abdomen terminate in a reddish membrane. [Synonymous with 
L. vittata Oliv.; common in Canada on flowers during June and July;

Taken in Nova Scotia by Dr. MacCulloch. 
Very nearly related to the preceding species, from which it differs 
chiefly in being much smaller, in having the underside of the body more 
thickly covered with hairs glittering like silver ; in having the throat pale- 
_ red; the fifth joint of the antennz longer than the fourth; the punctures 
of the elytra more numerous and scattered; the yellow stripe sunning 
nearer to the apex of the elytra, dilated at the base and not flexuose : the 
fore-breast also in the disk, the after-breast on each side, and the base of 
‘the thighs are obscurely red : the tibiæ are piceous. ae
