HESIODUS.—ILUS. 117 
feebly bisinuate, very finely and diffusedly punctured; elytra long, strongly convex, with regular rows of 
coarse longish impressions, the impressions becoming coarser and deeper outwardly, without impressed | 
striz, the interstices smooth, humeri distinct ; tarsi short. 
Length 543 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. Resembles Jsicerdes occultus, and the elytra sculptured as in that 
species, but very much smaller; the eyes more distant, the tibie not grooved on their 
outer edge. 
5. Hesiodus debilis, (Tab. VI. fig. 6.) 
Elongate oval, moderately convex, very dark reddish brown, shining. Head closely and rather coarsely punc- 
tured ; prothorax strongly transverse, subquadrate, about as wide behind as in front, the sides slightly 
rounded before the middle, almost straight behind, hind angles rectangular, the base feebly bisinuate, 
closely and rather coarsely punctured; elytra scarcely wider than the thorax, subparallel, punctate- 
striate, the punctures fine and approximate, the interstices finely, sparingly, and distinctly punctured, 
scutellar stria distinct, humeri subdentiform and impressed within ; antenne short, third joint short and 
scarcely as long as the united first and second joints, seventh to tenth joints strongly transverse ; tarsi 
short, stout, basal joint of the hinder pair the length of the two following joints united. 
Length 5 millim. . 
Hab. GuatTEMALA, Pantaleon (Champion). 
One example. Of the form of Isicerdes funebris; the structure of the posterior 
tarsi and the elytral sculpture much as in that species, but very much smaller, the eyes 
more distant, the tibie not channelled on their outer edge, the spurs of the inter- 
mediate and posterior tibiee short but distinct. 
ILUS. 
Form of Haplandrus femoratus, Fabr. Mentum trapeziform, trilobed, inflexed on each side, strongly raised and 
convex in the middle anteriorly, anterior angles distinct ; last joint of the maxillary palpi securiform ; 
antenne short, scarcely reaching to the base of the thorax, widening outwardly, third joint rather long 
and as long as the united first and second, fourth and fifth subequal and oboval in form, sixth and seventh 
much wider and subtriangular, eighth to tenth broad and transverse and widening outwardly, eleventh 
twice as long as and still broader than the tenth, and bluntly rounded at the apex; head short, broad, 
sunk into the prothorax to the eyes ; epistoma broadly truncated in front, short ; sides of the front feebly 
divergent and but little swollen; eyes distant, large, broad oval; labrum almost hidden from above ; 
prothorax very short, strongly transverse, very narrowly margined at the sides, strongly bisinuate at the 
base, hind angles divergent and acute, closely embracing the elytra; scutellum triangular ; elytra wider 
and moré than three times as long as the thorax, with regular rows of shallow rounded impressions 
and traces of obsolete stris ; epipleuree narrow, widened suddenly at the base, and ending about the last 
ventral suture; prosternum subhorizontal, broad, the apex slightly produced and in the form of a short 
blunt tooth, deeply impressed within, the centre raised and longitudinally convex ; mesosternum raised on 
each side, concave within ; anterior and intermediate femora scarcely swollen; intermediate cox oblique, 
the trochantin very small and narrow, and scarcely visible ; posterior femora widening on the inner side 
from the base to about the middle, then abruptly emarginate, thus forming a short broad triangular 
tooth; tibie curved, the extreme apices pubescent on their inner side, not grooved, the spurs of the 
anterior pair almost obsolete, of the hinder pairs short and distinct ; tarsi rather long, basal joint of the 
posterior pair the length of the two following joints united, and almost as long as the last joint. Winged.
