unequally punctured, but the impressions and dorsal channel in that species are much deeper, 
while the elevated spaces are almost smooth. 
D. fulgida, elongata, rufo-picea, cinero pubescens, thorace pube subflava densius vsrtito, 
punctate subcanaliculato, latitudine sesqui breviore, antrorsum angustato, lateribus rotundatis, 
pone medium sinuatis, postice parum angustato, angulis posticis prominulis, elytris thorace 
paulo latioribus rugose punctatis, lineis duabus solitis parum distinctis, viriditi3neis, epipleuris 
rufo-piceis, pedibus testaceis, tibiis tarsisque obscuris. Long. '37. 
Steilacoom ; Dr. Suckley. A little broader than D. elongata, and having the thorax formed 
as in D. testacea and Backii, from which it differs in color. 
Cerylon Latr. 
C. simplex, castaneum nitidum, elongatum minus depressum, thorace latitudine paulo 
longiore, lateribus postice parallelis, antice rotundatis, sat dense punctate, elytris striis 
punctatis fortiter impressis, interstitiis subconvexis. Long. 'lO. 
San Jose, California. The elytra are regularly although slightly convex transversely, and 
not at all flattened on the disc, as in C. castaneum and unicolor. fhe intervals between the 
striiB are somewhat convex, very finely and sparsely punctulate. The thorax is without disc- 
oidal impressions, and even the basal ones are hardly j^erceptible. 
Atomaria Kirby. 
A. laetula, oblonga, nigra, convexa, nitida, minus dense punctata, parce albo-pubescens, 
thorace convexo, rufo, antrorsum angustato, ad basin late rotundato et transversim impresso,

Variat supra nigra, elytrorum apice late rufo-testaceo. 
San Jose, California. Belongs to the second division of Erichson (Ins. Deutsch. 385,) having 
the antennae more distant from each other than from the eyes ; near the European A. unifas- 
ciata, from which it differs by the less dense punctuation. 
Pedilophorus Stefifahny. 
P. acuminatus, ovatus apterus, convexus, utrinque attenuatus, supra aeneus nitidus, cinereo- 
pubescens, thorace subtilius, elytris paroius punctatis ; subtus niger fortius punctatus cinereo- 
pubescens, tarsis piceis articulis tertio longe lobato. Long "IB. 
Morychus acuminatus, Mann. Bull. Mosc, 1852, 341. 
Sitkha^ Baron Chaudoir. Much broader than the next species, and gradually narrowed each 
way from the base of the elytra ; the latter are more sparsely punctured, and the pubescence, 
though not dense, is coarser. 
P. ohlongus, oblongo-ovaliS;, apterus, antice subacutus, convexus aeneus nitidus, subtilius 
cinereo-pubescens, thorace subtiliter, elytris distinctius punctatis ; subtus niger, fortius puncta- 
tus, cinereo pubescens,, tarsis piceis articulo tertio longe lobato. Long. 'IS. 
Pedilopliorus acuminatus % Lec. Proc. Acad. Nat. Sc. 7, 115. 
Oregon. The body is acutely narrowed from the base of the thorax forwards ; the thorax is 
a little more finely punctured than the elytra ; the latter are nearly parallel on the sides, and 
obtusely rounded behind.
