4, Agabus flohrianus. 
Elongatus, subdepressus, niger, antennis rufis, pedibus piceis ; superne subtiliter reticulatus, vel nitidus ( ¢), vel 
opacus (2); prothorace angusto, basin versus leviter angustato, angulis posterioribus obtusis. 
Long. 10 millim. 
Hab. Mexico, Amecameca in Morelos (Flohr, Hoge). 
Allied to A. cordatus, Lec., and A. amaroides, Sharp; it is distinguished from the 
latter by the peculiar form of the thorax, which, instead of becoming broader behind, 
is a little narrower at the base than it is in front, and much narrower than the base of 
the elytra. The upper surface is densely and finely reticulate, and there are three 
irregular series of punctures on each wing-case, and a minute depression on the disc of 
the thorax ; all the legs are elongate, the hind pair remarkably long and slender. The 
male, in addition to the surface being more shining than it is in the female, has the 
basal three joints on the front and middle feet a little incrassate. 
AGAMETRUS (to precede the genus Copelatus, p. 34). 
Agameirus, Sharp, Trans. Roy. Dubl. Soc. n. s. ii. p. 547 (1882). 
This genus has hitherto consisted of three species found in the north-west parts of 
South America. 
1..Agametrus nitens, 
Late ovalis, depressus, nitidissimus, niger, antennis palpisque rufis, capite anterius et in vertice prothoraceque 
ad latera rufescentibus, elytro singulo versus latus post medium puncto flavescente notato; prothorace 
basi utrinque sinuato, angulis posterioribus acutis; elytris omnino obsoletissime reticulatis. 
Long. 73, lat. 4 millim. 
Hab. Panama, Pefia Blanca 3000 feet (Champion). 
This insect is larger and more depressed than A. labiatus, and is destitute of the 
lateral linear rufescent marks on the elytra, and has the base of the thorax more sinuate 
on each side. Only one example was obtained; it is a male, and has very distinct 
sexual pubescence on the front and middle feet, and a few oblique scratches on each 
side of the middle of the last ventral segment.
