Fort Vancouver and Prairie Paso, Dr. Cooper. In one specimen tbe third joint of the 

 antennae is entirely black ; in the other it is pale at the base, like the following ones. This 

 species closely resembles L. obliterata, but the thorax is shorter and more broad behind. The 

 imjjressions are much stronger, and the disc is separated from the base by a sudden declivity. 

 The basal margin is yellov ; 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. 



The 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, fiavo-pubescens, capite thoraceque obscuris dense 

 punctatis, illo Irnea frontali subtili, thorace latitudine paulo longiore, convexo, lateribus postice 

 parallelis ad medium siibangulatis, 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. nitem, 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 hand 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. S. 



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, canaliculate, dense subtilius punctate, parceque 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.
