Temnochila Westwood. 
T. acuta, Isete viridi-aenea, cyaneo-micans, capite antice subtilius, postice 
vage grosse punctato, thorace latitudine haud longiore parcius punctato, lateri- 
bus late rotundatis, postice angnstato, angulis posticis haud prominulis, elytris 
thorace haud latioribus, humeris acutis, subrugosis seriatim subtilius puncta- 
tis, punctis postice minus profundis. Long. -58. 
One specimen, Texas, Mr. Haldeman. Resembles T. chlorodia, but the 
thorax is more regularly rounded on the sides, and less suddenly narrowed 
behind, and the posterior angles are not at all prominent ; the series of punc- 
tures of the elytra are less effaced towards the tip. 
T. aerea, olivaceo-aenea, subnitida, capite antice subtilius, postice vage 
grosse punctato, thorace latitudine haud longiore, lateribus antice parallelis, 
postice oblique angustato, angulis posticis paulo prominulis, elytris thorace 
haud latioribus, subtiliter rugosis, subseriatim punctatis, punctis postice paulo 
minus profundis. Long. -58. 
One specimen, San Francisco, California. Differs from the other species 
known to me by the rounded humeral angles of the elytra, the punctures are 
arranged in rows, but as they are all of the same size and not closely placed, 
the rows appear somewhat confused. 
Anchomma Lec. 
A. costatum, elongatum piceum opacum, punctatum, pube pallida rigida 
parce vestitum, capite margine late deplanato, utrinque late sulcato, thorace 
latitudine longiore lateribus pallidioribus, rectis marginatis, dorso acute bicos- 
tato ; elytris margine costisque utrinque tribus acute elevatis, interstitiis bi- 
seriatim punctatis ; antennis crassis rufo-piceis, oculis divisis. Long. 'IS. 
One specimen from the sea shore at San Diego, California. This new genus 
is closely allied to Corticus and Sarrotrium. The antennae are thick and setose : 
the first and second joints are equal, the third is nearly one half longer ; 4 — 10 
transverse, 11th narrower subquadrate. The sides of the head are dilated, so 
as to divide the eyes into two small linear portions, one superior, the other 
inferior. The mentum, palpi, feet and tarsi are as in Corticus. The first three 
Joints of the abdomen are equal in length, the fourth is shorter, and the fifth 
hardly longer than the fourth. 
DiTOMA Latr. 
D. sulcata, linearis, obscure ferruginea opaca, capite thoraceque scabris, 
parce setulosis, hoc marginato vix serrato, utrinque alte costato, elytris sutura, 
margine costisque utrinque quatuor acute elevatis, seriatim setulosis, inter- 
stitiis rugosis vix punctatis biseriatim setulosis. Long. '13. 
Colorado River, about Fort Yuma. 
D. o r n a t a , linearis depressa, picea opaca, capite thoraceque fortiter scabro- 
punctatis setulosis, hoc lateribus marginatis serratis, angulis anticis parum 
prominulis, omnibus rotundatis, utrinque bicostato, elytris sutura margine 
costisque quatuor acute elevatis seriatim setulosis, interstitiis biseriatim cri- 
bratis et breviter setulosis, macula subbasali alteraque pone medium magnis 
rufis utrinque ornatis, antennis pedibusque obscure ferrugineis. Long. -11 — '13. 
Found with the preceding. Larger and more depressed than D. quadri- 
guttata, with the angles of the thorax more rounded. 
Synchita Hellwig. 
S. variegata, oblongo-elongata, fusca opaca scabra, albo-setulosa, anten- 
nis pedibus elytrisque testaceis, his nigro-tesselatis, margine sutura costisque 
quatuor angustis elevatis, interstitiis biseriatim cribratis. Long. '09. 
Fort Yuma, Colorado River, California. Body oblong elongate, slightly con- 
vex, blackish brown ; head and thorax scabrous, covered with short white hairs, 
which are decumbent though rigid. Thorax not wider than long, not narrowed
