1853.] o85 



Two specimens from Santa Isabel, California ; another brighter colored one 

 from Sacramento, from Mr. Rathvon. Greenish black, or bright blue-green; 

 head sparsely f^unctnred and pilose, truncate at base, vertex with a red spot. 

 Antennae black, more than half as long as the body, very slightly thickened, 

 outer joints elongate, oval, last joint acuminate. Tliorax as wide as the head, 

 subquadrate, rounded anteriorly, spars^ly punctured, base moderately reflexed, 

 disc sometimes channeled and impressed. Elytra one half wider than the thorax, 

 parallel, scabrous, sprinkled with extremely short, indistinct hairs; middle tibiae 

 slender, slightly bent ; posterior tibiae as in the last, but the outer spur is less 

 dilated. 



14. L. stygica, atra, opaca, capite nitidiusculo, parce punctato, gutta ver- 

 ticali testacea, thorace sub-quadrato, vage punctato, basi reflexo, elytris scabris. 

 Long. 48--55.

Oregon. Entirely dull black, without lustre, except on the head. Head 

 parallel on the sides, almost truncate behind, occiput slightly channeled, vertex 

 with a testaceous spot. Antennce longer than the head and thorax, slightly 

 thickened externally, outer joints rounded oval. Thorax quadrate, rounded in 

 front, sparsely punctured, scarcely channeled, basal margin reflexed. Elytra 

 nearly twice as wide as the thorax, parallel, very scabrous. Legs as in the pre- 

 ceding species. 



1/). L. Rathvoni, capite thoraceque parce pnnctatis, viridi-aureis, illo 

 puncto verticali rubro, hoc ovali, latitudine longiore, elytris purpureis scabris, 

 antennis nigris elongatis. Long. -35. 



A beautiful little species found near Sacramento, California, by Mr. Child, 

 and given me by Mr. S. S. Rathvon. Head bright golden green, sparsely punctured, 

 with a few fine gray hairs ; occiput rounded; vertex broadly impressed, with a 

 small red >pot. Antennae black, joints 3-9, slender, scarcely increasing in thick- 

 ness, longer than the head and thorax, (remainder wanting.) Thorax shining 

 golden green, longer than wide, oval, sparsely punctured, base slightly reflexed. 

 Elytra a little wider than the head, coppery purple, scabrous, obsoletely 

 sprinkled with short hair. Beneath blackish green, with cinereous pubescence : 

 middle tibiae slender, slightly curved; (posterior tibias wanting.) 



16. L. 1 u g e n s, atra, parce pilosa, capite thoraceque nitidiusculis, parce 

 punctatis, hoc elongato antice angustato, elytris scabris. Long. 42-'5. 



Cantharis hi gens Le Conte, Ann. Lye. 5, 161. 



Abundant at San Diego, California. A long, slender, black species, resem- 

 bling some in Division (B.), but with the antennae of the present division. Head 

 moderately punctured and pilose, base broadly rounded, vertex slightly im- 

 pressed, not spotted. Antennas as long as the head and thorax, moderately 

 thickened externally, outer joints rounded, very little longer than wnde. Thorax 

 narrower than the head, one half longer than wide, narrowed at tip, base scarcely 

 at all marijined, disc sparsely punctured and pilose, scarcely impressed. Elytra 

 long, parallel, a little wider than the thorax, scabrous, sparsely pilose. Middle 

 tibice slightly curved ; posterior tibiae with the outer spur a little thicker than 

 the inner one, concave and slightly obtuse at apex. 



The difference between the spurs of the posterior tibias is not obvious, except 

 on very close inspection, but the appearance of the species refers it to this divi- 

 sion rather than to those with two acute spurs on the posterior tibise.

 punctatis, hoc subcampanulato, antice impresso, elytris convexis postice latiori-
