328 RHYNCHOPHORA. 
the head and prothorax, rugosely punctate to the tip. Prothorax broader than long, transversely convex, 
narrowing from the base, rounded at the sides anteriorly, strongly constricted in front ; densely, finely, 
rugulosely punctate, and with indications of a raised median line. Elytra shining, narrowly striate, the 
interstices very broad, flat, and densely, finely punctate. Beneath closely, the middle of the metasternum 
and abdomen more sparsely, punctate; first ventral segment broadly excavate. 
Length 4-43, breadth 23-23 millim. (¢.) 
Hab. Mexico (Mus. Brit.) ; Guatemaua, Capetillo (Champion). 
Two males, the one from Mexico somewhat abraded. A broad, rhomboidal form, 
with a large patch on each side of the prothorax at the base and two broad fascie on 
the elytra ochraceous, the rostrum rather short, stout, and rugosely punctate, the 
femora and prosternum sulcate, the anterior tibie hollowed at the apex externally. 
CESENNIA, gen. nov. 
Rostrum arcuate, moderately long; mandibles curved, stout, decussate at the tip; antenne inserted at 
about the middle of the rostrum, stout, the scape clavate at the apex, joints 3-7 of the funiculus 
strongly transverse, widening outwards, the club ovate; prothorax tubulate in front; scutellum free; 
elytra much wider than the prothorax, subtriangular; pygidium not visible; prosternum unarmed, 
declivous and broadly depressed down the middle anteriorly, deeply bifoveate in front, the space between 
the widely-separated anterior coxe flattened; tibie strongly unguiculate; tarsal claws free; body 
rhomboid-ovate, squamose. 
Type, C. latecincta. 
The single species placed under Cesennia is very like Gerwopsis duplocinctus, but 
the general structure is different: the mandibles are curved externally, the prosternum 
is deeply bifoveate in front (instead of narrowly sulcate down the middle), the outer 
joints of the funiculus are short and stout (though the club is of normal size), the 
anterior coxe are very widely separated, and the femora are not sulcate beneath. 
1. Cesennia latecincta, sp.n. (Tab. XVII. figg. 10, 10a, 3.) 
Nigro-piceous, the antenne, tibia, and tarsi obscure ferruginous; the elytra each with a very broad, common, 
arcuate, transverse band of narrow ochreous scales beyond the middle and the rest of their vestiture 
almost entirely dark brown; the prothorax, the base of the rostrum, under surface, and legs with 
small scattered ochreous or whitish scales. Head closely punctate; rostrum rather longer than the 
head and prothorax, much thickened towards the base, flattened and more slender in its apical half, 
striate-punctate. Prothorax transverse, strengly rounded at the sides anteriorly, narrow and tubulate 
in front; densely, finely, rugulosely punctate. lytra gradually narrowing from the base, finely 
punctate-striate, the interstices broad, flat, and densely punctate. Beneath densely, the abdomen 
sparsely, punctate. First ventral segment depressed along the middle. Anterior tibie narrow, slightly 
hollowed externally. 
Length 32, breadth 2 millim. (d.) 
Hab. Paxama, Volcan de Chiriqui 4000 feet (Champion). 
One male. Narrower than Gerwopsis duplocinctus, the elytra less widened at the 
base and each with a single arcuate fascia, the rostrum tapering outwards.
