MNEMYNURUS. 51 
8. Mnemynurus phenicoderes, sp. n. (Tab. III. fig. 29.) 
Rhomboidal, piceous or reddish-brown, the legs sometimes ferruginous, the antenne testaceous, the vestiture 
fine above: the head white between and behind the eyes, fulvous or red on the vertex ; the prothorax 
with a narrow, sharply-defined, sinuous, white fascia behind the middle, which extends narrowly down 
the centre of the median lobe to the base and is continued around the flanks beneath, the base itself 
also bordered with white towards the sides, the anterior half carmine-red; the elytra brownish or 
cinereous, the narrow cinereous scales here and there clustered into patches on the basal half of the dise 
and along the sides ; the scales on the under surface white, ochreous at the sides of the metasternum, 
the ventral segments 2-4 with two almost bare stripes, which extend outwards along the base of 2, 1 also 
bare at the sides in front ; the legs cinereous or whitish, the femora fulvous at the base above. Head 
densely punctate, except along the smooth raised median space on the vertex, the eyes well-separated 
above ; rostrum nearly reaching the first ventral suture, rugulose and carinate at the base, and smooth 
thence to the tip. Prothorax conical, about as long as broad, flattened on the disc; densely, rather 
coarsely punctate, except along the smooth median line. Elytra somewhat cordate, blunt at the apex, 
depressed along the suture; punctate-striate, the interstices rugulose, the inner ones flat, the outer ones 
convex. Legs elongate; femora each with a small sharp tooth, the knees sharply dentate. 
Length 54-64, breadth 23-27 millim. 
Hab. Panama, Bugaba (Champion). 
Five specimens. Smaller than JV. caloderes; the prothorax with a narrower, more 
sharply-defined, white, post-median fascia, extending narrowly down the median lobe 
to the base, the disc less convex, and the median carina almost obsolete; the eyes less 
approximate above; the fifth elytral interstice not prominent. ‘The conical prothorax, 
&e., separate WZ. phenicoderes from M. ignifer. 
4, Mnemynurus erythroderes, sp. n. (Tab. III. fig. 30.) 
Rhomboidal, black, the anterior half of the prothorax rufo-piceous, the antennal club and the tip of the 
rostrum rufescent, the vestiture fine above: the head whitish between and behind the eyes, fulvous on 
the vertex ; the prothorax with a short streak down the middle behind, a sharply-defined, transverse, 
interiorly narrowed, post-median fascia on each side of it, extending around the flanks beneath, and a 
space along the base, yellowish-white, the anterior half rust-red; the elytra brownish, mottled with 
flavyo-cinereous, the flavo-cinereous scales condensed into interrupted lines or spots on the alternate 
interstices at the base ; the scales on the under surface white, the ventral segments 2-4 with two almost 
bare stripes, which extend outwards along the base of 2,1 bare at the sides in front, the metathoracic 
episterna with the anterior portion also bare. Head densely punctate, except along the smooth raised 
median space on the vertex, the eyes rather narrowly separated above ; rostrum nearly reaching the first 
ventral suture, rugulose and carinate at the base, and smooth thence to the apex. Prothorax broader 
than long, conical, slightly rounded at the sides posteriorly, somewhat flattened on the disc; densely, 
finely punctate, and obsoletely carinate. Elytra subcordate, blunt at the apex, depressed along the 
suture; punctate-striate, the interstices 5, 7, and 9 convex. Legs elongate ; femora each with a narrow 
sharp tooth, the knees sharply dentate. 
Length 5-54, breadth 23-3 millim. 
Hab. Payama, Bugaba (Champion). 
Two specimens. Very like UM. phenicoderes, but with the prothorax more finely 
punctate, the whitish transverse fascia narrowing inwards and not reaching the short 
median basal vitta, the vestiture of the anterior half rust-red; the elytra with the 
alternate interstices interruptedly lineate at the base, 5, 7, and 9 raised; the under 
surface with several bare dark spaces along the sides.
