Fort Vancouver and Prairie Paso, Dr. Cooper. In one specimen tbe third joint of the 
antennae is entirely black; in tbe other it is pale at tbe base, like the following ones. This 
species closely resembles L. obliterata, but tbe thorax is shorter and more broad behind. The 
impressions are much stronger, and the disc is separated from the base by a sudden declivity. 
The basal margin is yellow ; and on the elytra there is no trace of the two spots before the 
middle, seen in S. obliterata , and the apex is not at all rufous. 
Tbe testaceous sides of the thorax and annulated antennae were not mentioned in the descrip¬ 
tion given by me of Strangalia obliterata , (Journ. Ac. Nat. Sc. 2d ser. 1, 328,) as, on account 
of the very dark color of the only specimen then known to me, they were not observed. 
L. impura, longiuscula, sordide testacea, flavo-pubescens, capite thoraceque obscuris dense 
punctatis, illo linea frontali subtili, thorace latitudine paulo longiore, convexo, lateribus postice 
parallelis ad medium subangulatis, ad apicem breviter constricto ; elytris confertim punctatis, 
macula rotundata submarginali ad medium nigricante notatis, a humeris postice subangustatis 
ad apicem oblique truncatis. Long. '4. 
One specimen, without antennae, sent by Mr. Wittick from Sacramento. Quite distinct from 
every other species known to me, and, although of a slender form, seems to belong to the (A—7) 
division of Strangalia.—(Vide Journ. Acad. Nat. Sc. 2d ser. 1, 332.) 
L. laeta, crassiuscula nigra dense sericeo aureo-pubescens, thorace convexo, utrinque con¬ 
stricto, lateribus valde rotundatis, medio tuberculatis ; elytris nigris, fasciis quatuor latis flavis 
aureo-pubescentibus, fasciis secunda et tertia ad suturam connexis ; pedibus ferrugineis, anten¬ 
nis corporis dimidio haud longioribus crassis, oreque obscure ferrugineis. Long. - 6. 
California, at Sacramento, Mr. Wittick ; Steilacoom, Mr. Gibbs. A very beautiful species, 
allied to L. nitens , but very distinct. Tbe anterior yellow fascia is curved, and sometimes con. 
nects with the second at the suture. 
L. amabilis, elongata nigra, supra parce subtiliter pubescens, capite thoraceque confertissime 
punctatis, hoc latitudine haud longiore, antrorsum angustato, lateribus rotundatis, ad apicem 
constricto, ante basin transversim impresso, angulis posticis acutis ; elytris intra humeros 
longius impressis, confertim punctatis, macula rotundata prope scutellum, fascia postice obliqua 
ante medium, altera latiore ad trientem ab apice, et macula rotundata ante apicem pallide 
flavis, postice subangustatis, ad apicem oblique emarginatis; antennis pedibusque obscure 
ferrugineis, femoribus infuscatis. Long. *3. 
A very beautiful little species, of which a single specimen was collected by Mr. Gibbs at 
Steilacoom. It belongs, with the preceding, to division (A— 7) of Strangalia. 
L. valida, elongata, testacea, subtilius pubescens, thorace parvo latitudine longiore, ante 
medium angustato, utrinque constricto, canaliculato, dense subtilius punctato, pareeque grosse 
punctato ; elytris thorace duplo latioribus, nebulis duabus ante medium, duabus ad medium 
alteraque maiore ante apicem fuscis, parallelis postice obtusis, spina suturali prominula. Long.
