374 RHYNCHOPHORA. 
Six specimens. Smaller and shorter than JM. bistrigellus, the elytra with the whitish 
spot at the base of the third interstice less elongate, the strie broader and deeper, the 
interstices not so smooth, the prothorax more coarsely punctate, the prosternum (as 
in MW. tumefactus) transversely tumid or lamellate between the coxe anteriorly in 
the male. 
19. Madarus brevilinea, sp. n. (Tab. XIX. figg. 5, 5a, 3.) 
Somewhat fusiform, sneous, shining; the sides of the prothorax, the elytra (a broad space along the suture 
excepted), under surface, and legs sparsely clothed with small, hair-like, ochreous or cinereous scales, the 
third elytral interstice with a dense line of rather coarser, similarly-coloured scales at the base. Head 
finely punctate, transversely depressed between the eyes; rostrum strongly arcuate, stout, usually about 
as long as the head and prothorax, closely punctate, the apical portion much smoother in the °. 
Prothorax broader than long, rounded at the sides, rapidly narrowed in front; closely punctate, the 
punctures transversely confluent on the flanks. Elytra not wider than the prothorax, transversely 
depressed on the disc anteriorly; very finely striate, the interstices with minute, scattered punctures, 
which become asperate laterally, the third about equal in width throughout. Pygidium large, prominent. 
Beneath coarsely and rugosely, a broad space along the middle of the metasternum and abdomen very 
sparsely and finely, punctate. Prosternum not or feebly bifoveate in front. Anterior femora obsoletely 
dentate, the others sulcate beneath. 4 
¢d. Anterior tarsi slightly dilated and hairy ; prosternum somewhat tumid between the coxe anteriorly. 
Length 5-53, breadth 2-2} millim. (¢ 2.) 
Hab. Mexico, Playa Vicente (Sallé), Cordova (Hoge), Teapa (Hoge, H. H. Smith). 
Ten specimens, varying greatly in the length of the rostrum, apparently all females 
but one. Separable from WM. distigma, &c., by its rather narrow form, the bright 
veneous surface, the fine vestiture, the narrower ochreous or whitish streak at the base 
of the third elytral interstice, aud the very finely striate elytra. 
20. Madarus macrogrammus, sp. n. (Tab. XIX. figg. 6, 6a, 3.) 
Madarus macrogrammus, Jekel in litt. 
Somewhat fusiform, broad, bronze-black, shining; somewhat thickly clothed (a broad space along the middle 
of the prothorax, the scutellum, and the first and second elytral interstices excepted) with narrow, hair- 
like, fulvous or fulvo-cinereous scales, the elytra with a dense ochreous vitta extending down the third 
_ interstice from the base to near the apex. Head closely punctate ; rostrum strongly arcuate, about as 
long as the head and prothorax, thickened towards the base, closely punctate, the apical portion in the 2 
abruptly narrowed and almost smooth, the antenne inserted at or a little behind the middle. Prothorax 
transverse, rather convex, rounded at the sides anteriorly, rapidly narrowed from about the middle, 
feebly constricted in front; closely punctured, the punctures becoming transversely confluent towards 
the sides. Elytra subtriangular, not or scarcely wider than the prothorax, transversely depressed on the 
disc anteriorly ; narrowly striate, the interstices finely punctate, becoming asperate towards the sides, 
the second very gradually widened towards the base. Pygidium large, prominent. Beneath rugosely, 
a broad space along the middle of the metasternum and abdomen very sparsely and finely, punctate. 
Prosternum bifoveate near the apex. Anterior femora not or obsoletely dentate. 
¢. Anterior tarsi slightly dilated, hairy, the anterior tibie also with a few hairs within. 
Length 43-63, breadth 2-24 millim. (d 9.)
