012 RHYNCHOPHORA. 
1. Mecistocorynus sinuatipes, sp.n. (Tab. XXV. figg. 14, 14a-c, 3.) 
Black, shining, the antennz obscure ferruginous ; variegated with brown. fulvous, and white scales, the white 
scales more or less condensed into an interrupted curved or oblique line on each side of the disc of the 
prothorax, the two lines becoming confluent in front, and a transverse humeral patch and a postmedian 
fascia on the elytra, the disc of the latter usually mottled with black, the femora and tibie annulate with 
white, the scales on the pronotum and under surface larger than those on the elytra. Head densely 
punctate ; rostrum (¢ ) curved, rugulosely punctate in its basal half and sparsely punctate thence to the 
apex, (2 ) almost straight and smoother throughout; antenne with joints 1 and 2 of the funiculus subequal 
in length in the 9, 2 longer in the ¢, the club nearly as long as the funiculus in the 2? and equalling 
joints 2-7 of the latter in the ¢. Prothorax broader than long, rounded at the sides, feebly constricted 
and much narrowed in front, as wide as or wider than the prothorax in the ¢, narrower in the 9; densely 
punctate and sparsely granulate, and also feebly carinate. Elytra narrowing from a little below the 
base, flattened along the suture anteriorly; seriate-punctate, the interstices granulate, 3, 5, 7, and 9 
raised, Beneath coarsely, closely punctate. 
Length 83-114, breadth 33-4? millim. (¢ 2.) 
Hab. Mexico, Chilpancingo, Cordova (Hége), Tehuantepec (Sal/é); GUATEMALA, 
Torola, Pacific slope (Champion). | 
Found in numbers at Torola, on fallen timber, females predominating. The peculiar 
structure of the front legs of the male is given under the definition of the genus. 
MACROMEROPSIS, gen. nov. 
Rostrum moderately long, curved, subcylindrical ; eyes very large, finely facetted, rather narrowly separated ; 
antenne inserted behind the middle of the rostrum, joint 2 of the funiculus elongate, the club subcylin- 
drical or ovate, with distinct sutures ; prothorax broader than long, bisinuate at the base, the subrectangular 
hind angles received into the excavate base of the elytra, the ocular lobes feebly developed ; scutellum 
rounded ; elytra much wider than the prothorax, with ten rows of punctures, villose or ciliate at the 
sides in the 3; rostral canal extending to the anterior limit of the metasternum ; metasternal episterna 
broad ; ventral segment 2 as long as 3 and 4 united, the first suture arched; femora clavate, unidentate, 
the anterior pair subequal in length in the two sexes, the posterior pair scarcely reaching beyond the apex 
of the elytra; tibia rugose and feebly carinate, strongly unguiculate ; anterior tarsi clothed with long 
projecting hairs, and sometimes dilated, in the g; tarsal claws simple; body robust, subovate, winged, 
squamose. 
The two species referred to this genus are of large size, and they have the general 
facies of Hilipus suspensus and its allies. In the British Museum there is an unnamed 
allied South-American form with the sides of the elytra still more hairy. 
1, Macromeropsis binotatus, sp.n. (Tab. XXV. fige. 15,15 a, ¢; 150, an- 
terior tarsus, ¢ .) 
Subovate, robust, dull, black, the antenna obscure ferruginous ; mottled above with a dense clothing of fulvous 
and black scales, the black scales condensed into a sinuous, anteriorly narrowed vitta on each side of the 
disc of the posterior portion of the prothorax, and also clustered into a large irregular patch around the 
subquadrate white spot on the disc of each elytron beyond the middle, the scutellum and a small spot on 
the flanks of the prothorax white or ochreous; the elytra moderately ciliate at the sides in the ¢; the 
vestiture of the under surface sparse and pale, that of the legs closer, the scales on the latter sometimes in 
great part fulvous (in one specimen carmine-red), the tibize annulate with fuscous near the base. Head 
rugosely punctate, subgranulate and carinate ; rostrum rugulose and 5-carinate in its basal third, and 
thence to the apex almost smooth, the antenne inserted behind the middle, joint 2 of the fuuiculus
