54 RHYNCHOPHORA. 
narrowing from a little below the base, the obliquely truncated humeri almost in a line with the sides of 
the prothorax, the basal margin sharply raised; deeply punctate-striate, the interstices punctulate and 
almost flat. Mesosternum subvertical, with a narrow transverse depression between the cox limited in 
front by an arcuate ridge. Metasternum shallowly depressed down the middle. Legs very long, slender ; 
femora unidentate, the anterior pair sometimes unarmed, the intermediate and posterior pairs carinate 
externally ; knees with a sharp spine. 
Length 5-74,, breadth 23-3? millim. (d 9.) 
Hab. Guatemata, Las Mercedes, Pantaleon, Zapote, Teleman (Champion).—Sovtu 
America, Cayenne, Amazons (lus. Brit.). 
Six specimens from Guatemala, two from Cayenne, and one from the Amazons. ‘This 
species is very like a Mnemynurus, but it has a shorter rostrum. 
2. Hoplocopturus nigripes, sp.n. (Tab. IV. figg. 4, 4a, 8.) 
Subovate, black, the antenne ferruginous; above thickly clothed with narrow scales: the anterior half of the 
prothorax and a line behind the eyes carmine-red, the space between them white, the prothorax with a 
narrow fascia near the base, extending down the median lobe, and the elytra with the base, two undulate 
fascia, and an oblong patch on the suture at the apex, also white, the rest of the upper surface blackish, 
the two blackish elytral fasciz extending downwards on to the side-pieces of the metasternum ; the 
under surface closely set with coarser, oval, white scales, the legs with piliform, white scales. Head 
broad, closely punctate, the eyes separated by a narrow space; rostrum reaching the middle of the 
metasternum, rugulose and carinate at the base. Prothorax nearly twice as broad as long, obliquely 
narrowing from the base, the anterior constriction indistinct ; densely punctate. Elytra short, rounded- 
triangular, blunt at the apex; punctate-striate, the interstices rugulose, flat. First ventral segment 
broadly depressed down the middle in the ¢. Legs moderately long, the posterior femora extending 
beyond the apex of the abdomen; anterior and intermediate femora obsoletely, the posterior femora 
distinctly, unidentate ; anterior knees feebly, the others sharply, dentate. 
Length 3, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
Two specimens. This insect resembles Mnemynurus longispinis, but it has the 
rostrum and legs shorter and blacker, the eyes less approximate, the prothorax 
shorter, the elytra with sharply-defined, complete, light and dark fascie, the latter 
extending downwards on to the sides of the metasternum. The head is much broader 
than in H. leptopus, H. varipes, and H. armatus. 
3. Hoplocopturus quinquevittatus, sp.n. (Tab. IV. fige. 5, 5a; 56, meso- 
sternum.) 
Elliptic, flattened above, shining, black, the antenne ferruginous; the head with a line around eyes, the 
prothorax with five narrow vitte (the outer ones scarcely visible from above), and the elytra with 
the basal margin, the suture, two undulate transverse fascize on the disc, and a narrow streak at the apex 
of the seventh interstice, yellowish-white, the rest of the vestiture of the upper surface sparse and 
blackish; the under surface and legs with yellowish-white scales, the ventral segments 1-4 with a 
broad space down the middle, 1 and 2 also with a space at the sides, and 5 entirely, infuscate or bare. 
Kyes extremely large, very narrowly separated. Rostrum rugulose and carinate at the base. Joint 2 of 
the funiculus as long as3—7 united. Prothorax much broader than long, narrowing from the base, feebly 
constricted in front; closely, rather coarsely punctate, the punctures on the middle of the disc transverse. 
Elytra oblong-cordate ; deeply punctate-striate, the interstices almost flat, rather sparsely, minutely 
punctate. Meso- and metasternum depressed between the middle cox, the mesosternal depression limited
