Two specimens from Santa Isabel, California; another brighter colored one 
from Sacramento, from Mr. Rathvon. Greenish black, or bright blue-green; 
head sparsely punctured and pilose, truncate at base, vertex with a red spot. 
Antenne black, more than half as long as the body, very slightly thickened, 
outer joints elongate, oval, last joint acuminate. ‘Thorax as wide as the head, 
subquadrate, rounded anteriorly, sparsely punctured, base moderately reflexed, 
disc sometimes channeled andimpressed. Elytra one half wider than the thorax, 
parallel, scabrous, sprinkled with extremely short, indistinct hairs ; middle tibize 
slender, slightly bent; posterior tibize as in the last, but the outer spur is less 
dilated. 
14. L. stygica, atra, opaca, capite nitidiusculo, parce punctato, gutta ver-

Cantharis stygict Le Conte, Ann. Lyc. 5, 161. 
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. Antenne 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. 
15. L. Rathvoni, capite thoraceque parce punctatis, 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. 8.8. Rathvon. Head bright golden green, sparsely punctured, 
with a few fine gray hairs; occiput rounded; vertex broadly impressed, with a 
small red spot. Antennz 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 tibice slender, slightly curved; (posterior tibie wanting.) 
16. L. lugens, atra, parce pilosa, capite thoraceque nitidiusculis, parce 
punctatis, hoc elongato antice angustato, elytris scabris. Long. -42--5. 
Cantharis lugens 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 antenne of the present division. Head 
moderately punctured and pilose, base broadly rounded, vertex slightly im- 
pressed, not spotted. Antenne as long as the head and thorax, moderately 
thickened externally, outer joints rounded, very little longer than wide. Thorax 
narrower than the head, one half longer than wide, narrowed at tip, base scarcely 
at all margined, disc sparsely punctured and pilose, scarcely impressed. Elytra 
long, parallel, a little wider than the thorax, scabrous, sparsely pilose. Middle 
tibie slightly curved; posterior tibize 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 tibiz 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 tibiz.
