Fort Vancouver and Prairie Paso, Dr. Cooper. In one specimen tbe tbird joint of tbe 
antennae is entirely black ; in tbe otber it is pale at tbe base, like tbe following ones. Tbis 
species closely resembles L. obliterata, but tbe tborax is sborter and more broad bebind. The 
impressions are mucb stronger, and tbe disc is separated from tbe base by a sudden declivity. 
Tbe basal margin is yellow ; and on tbe elytra tbere is no trace of tbe two spots before tbe 
middle, seen in S. obliterata, and tbe 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 baud 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. The 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 baud longiore, antrorsum angustato, lateribus rotundatis, ad apicem 
constrictOj 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 tbe 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 punctate, parceque grosse 
punctate ; elytris thorace duplo latioribus, nebulis duabus ante medium, duabus ad medium 
alteraque maiore ante apicem fuscis, parallelis postice obtusis, spina suturali prominula. Long.

One specimen, from Shoalwater Bay, Dr. Cooper. Of the anterior spots, the inner is larger;
