596 On Aquatic Carnivorous Coleoptera or Dytiscide. 
I. 55.—Genus AGLYMBUS. 
Coxal lines quite obliterated ; upper surface bearing a sculpture of short lines. 
The seven species of this genus are with two exceptions South American, and are 
extremely rare in collections. The two Abyssinian species will probably prove 
another genus. 
897. Copelatus rufipes, Brullé, Agabus rufipes, M.C.—Ovalis, elongatus, sat 
angustus, nitidus, subtus piceo-rufus, supra niger, capite, prothoracis lateribus, 
elytris fascia basal, macula laterali signaturaque apicali, antennis pedibusque 
testaceis ; prothorace strigis haud subtilibus numerosis impressis, elytris in parte 
basali strigis similibus, in parte apicali fere levigatis. Long. 74, lat. 25 m.m. 
The male has the second and third joints of the front and middle tarsi a good deal 
thickened. The fem-le I have not seen. A variety occurs (in the same localities 
as the type form) having no trace of the basal fascia on the elytra. 
South America, (Brazil). 710. 
898. Agabus leprisuri, Aube, M.C.—Ovalis, minus nitidus, piceus, supra 
nigricante, capite elytrisque apice dilutioribus, prothoracis lateribus antennis 
pedibusque ferrugineis ; thorace elytrisque lineolis brevibus, profundis et 
numerosis impressis, illis versus elytrorum apicem obliquis. Long. 63, lat. vix 
32 m.m. 
The male differs from the female only by a slight incrassation of the basal joints 
of the front and middle tarsi. The species is readily recognized by its peculiar 
sculpture ; the specimens before me show some variation in size and form, and 
also in the number of the scratches on the thorax and elytra. 
South America, (Cayenne). 711. 
899. Aclymbus sculpturatus, n. sp.—Ovalis, fere opacus, piceus, supra nigricante, 
eapite elytrisque limbo dilutioribus, prothoracis lateribus antennis pedibusque 
ferrugineis ; thorace elytrisque lineolis profundis densis, impressis, illis versus 
apicem obliquis. Long. 6, lat. 84 m.m. 
This species is narrower in front and therefore more oval in form than in Agabus 
leprieuri (No. 898) and has the sculpture of the upper surface denser. The single 
individual I have seen isa male, and has the front and middle tarsi very little 
incrassate. 
South Americas, (Para, Bragance; de Mathan). 712.
