Hab. Mexico, Toxpam (Sallé), Juquila (Hoge); GuatTeMata, Las Mercedes [type] 
(Champion). 
‘Three specimens. 
19. Goniocleus pusillus, sp. n. (Tab. XII. figg. 11, 11a.) 
2. Rufescent, clothed with a clayish-coloured pubescence. Rostrum nearly twice as broad as long, with a 
feebly elevate short mesial carina, longitudinally punctate-rugate like head. Frons nearly two-thirds the 
width of the rostrum. Segments 9 and 10 of the rufous antenna brown, 9 a little longer than apically 
broad. Prothorax broader than long, widest at angle of carina, blackish above, except apical margin, 
which is rufous, this colour gradually more extended laterally, a blackish half-ring expanding from side 
to side and bordering the rufescent apical portion is without clayish-coloured pubescence ; middle of 
pronotum without large punctures; callosities vestigial ; dorsal carina very feebly convex, practically 
straight, lateral angle distinct, though strongly rounded. Elytra each rounded at basal edge between 
scutellum and humeral depression, short, deeply striate-punctate, the alternate interspace subcarinate ; 
three black-tufted tubercles in third interspace, of the same size and equidistant, not much elevate, a 
minute fourth tubercle farther backwards; some black pustules in fifth interspace and a number of black 
dots farther laterally; sutural angles not elevate. Underside pubescent-grey. Legs rufous, greater 
portion of femora and middle of tibie brown. 
Length 33-4 millim. 
Hab. Guatemata, El Tumbador, Zapote (Champion); Panama, Volcan de Chiriqui 
(Champion). 
Three females. 
20. Goniocleus icas, sp. n. (Tab. XII. fig. 12.) 
2. Brownish-black; upperside pubescent clay-colour, irrorated with brown and black, second and third 
tubercles of elytron black, apical declivity of elytra and pygidium evenly pubescent-clay-colour, this area 
truncate in front and sharply defined ; underside more grey. 
Rostrum half as wide again as broad, rugosely punctured like head. Frons half the width of the rostrum. 
Shaft of antenna and tip of last segment rufescent, club brown, segment 9 as broad at apex as long. 
Prothorax broader than long, widest at angle of carina, without large punctures on notum, except some 
laterally ; callosities obsolete, hardly traceable ; dorsal carina practically straight, the lateral angle a little 
over 90°, with the apex rounded off. Elytra each with rounded basal edge; punctures less deep than in 
the preceding species and interspaces more even ; three rounded and moderately elevate tubercles in third 
interspace, some feebly raised black dots in fifth, seventh, and ninth interspaces. Legs somewhat 
rufescent, especially the tarsi; tibiae not distinctly ringed. 
Length 4 millim. 
Hab. Mexico, Juquila (Sal/é). 
Two females. 
21. Goniocleus ornaticeps, sp.n. (Tab. XII. fig. 13.) 
2. Brownish-black, pubescent cinnamon-brown above variegated with grey, grey beneath variegated with 
brown at sides; a spot on each side at base of rostrum, an interrupted border to eye, a mesial dash and 
two basal spots on pronotum, and two spots at base of pygidium, ochreous. 
Rostrum nearly twice as broad as long, punctate-rugulose, with trace of a smooth mesial carina. Frons half 
the width of the rostrum. Occiput somewhat convex, not flattened. Eyes about one-fourth longer than 
wide. Antenna brown, club broad, segment 9 as broad at apex as long. Prothorax broader than long, 
widest at angle of carina, without large punctures on notum, but with two small rounded tubercles and
