HAMMATOSTYLUS.—LUDOVIX. 273 
Chevrolat in his genus Hammacerus (a name long preoccupied in Hemiptera), but 
cannot be satisfactorily identified with any of them. It comes nearest H. brenthoides, 
but is narrower and has fewer bristles on the elytra.

Chevrolat takes Torophorus fasciatus, Gyll. (=tantalus, Rosensk.), from Tropical 
South America, as the type of Zudovix, and the species now added is a nearly allied 
form. These insects have the rostrum slender, curved, and in the male much shorter 
than in the female (in which sex it is as long as the body), the scrobes in both sexes 
extending as far as the eyes, which are well separated above, the second joint of the 
funiculus nearly three times as long as the third, the scutellum comparatively large, 
and the tarsal claws armed with a long slender tooth. ‘The scattered vestiture is 
coarse and squamiform, instead of long and bristly as in Hrodiscus, &c. 
1. Ludovix bifasciatus, sp. n. (Tab. XIV. figg. 8, 8,8, 3.) 
Elongate, narrow, subcylindrical, shining, rufous, the basal half of the rostrum, the head, the scutellum, two 
fascize on the elytra—one at the base, the other, wider, beyond the middle,—the meso- and metasternum, 
the coxse, and the knees broadly, black ; the elytra with scattered, coarse, white, semierect, squamiform 
hairs, the meso- and metasternum and the sides of the abdomen somewhat thickly clothed with elongate, 
adpressed, white scales. Head small, convex, smooth, faintly foveate between the eyes, which are large 
and somewhat widely separated; rostrum slender, curved, a little shorter than the elytra, smooth, the 
antenne inserted about the middle, joint 2 of the funiculus elongate, as long as 3-5 united. Prothorax 
convex, a little longer than broad, rounded at the sides, much narrowed and constricted both at the base 
and apex, sparsely, rather coarsely punctate, the punctuation becoming coarser on the flanks, a space down 
the middle of the disc impunctate. Elytra elongate, scarcely wider than the prothorax, subparallel in 
their basal half, flattened on the disc, the humeri obtuse ; rather coarsely seriate-punctate, the interstices 
narrow, with widely scattered, coarse punctures. Meso- and metasternum coarsely punctate, the base of 
the abdomen also with a few coarse punctures. Ventral segments 1, 2, and 5 more or less depressed 
along the middle, the depression on 5 broad, rugulosely-punctate and pubescent at the tip. Legs long ; 
femora each armed with a short tooth beneath; tibiee sinuate within; tarsi moderately long, joint 1 
nearly as long as 2-4 united, the claws with a long fine tooth. 
Length 53-63, breadth 14 millim. (d.) 
Hab. Panama, David in Chiriqui (Champion: ¢ ).—Gutana, Cayenne (Mus. Brit.: 2 ). 
Perhaps a variety of L. fasciatus, from which it differs in the shorter rostrum of 
the g, the shorter prothorax, the bifasciate elytra, and the black head, basal half of 
the rostrum, and knees. The description is taken from two males from Chiriqui, and 
there is a female from Cayenne, in the British Museum, with a very much longer 
rostrum, that doubtless belongs to the same species.
