ISICERDES.—HESIODUS. 115 
sides ; prosternum deflexed behind, the apex broad, slightly produced, and margined within ; tibiz feebly 
channelled on their outer edge, spurs almost obsolete. 
Length 8 millim. 
Hab. GuateMa.a, Zapote (Champion). 
Two examples. Closely allied to a species from Colombia*, but longer, and the elytra 
more finely punctate-striate. Of a different facies from J. occultus; flatter, less convex, 
the thorax less distinctly margined at the sides; the elytra punctate-striate, the tibiz 
less distinctly channelled, &c. 
HESIODUS. 
Allied to Isicerdes, and differing as follows:—Head shorter, rather more deflexed, more deeply sunk into the 
thorax; the epistoma shorter, broadly rounded in front; the sides of the front very slightly swollen, 
almost equally rounded with the epistoma, and scarcely divergent ; labrum not visible from above; eyes 
more distant, more rounded and less transverse ; antenne as in Jsicerdes; prothorax narrowly margined 
at the sides, the margins sometimes indistinctly crenulate, strongly transverse, the base bisinuate, closely 
embracing the elytra; scutellum moderate in size, triangular; elytra and epipleure as in Jsicerdes; 
prosternum subhorizontal, the apex slightly produced and rounded; mesosternum simple ; trochantin 
distinct ; tibie not channelled on their outer edge, the spurs small, the posterior pair very slightly swollen 
about the middle in the male; femora unarmed; tarsi variable, long and thin, and the basal joint longer 
than the two following joints united, or (as in Jsicerdes) shorter and stouter, and the basal joint the length 
of the two succeeding joints united. Winged. Species shining, slightly metallic or black. 
This genus will include a few small and inconspicuous species from Central and South 
America, and probably the North-American Haplandrus ater, Lec., which, on account 
of the differences in the structure of the head, tibie (the spurs of the anterior pair 
obsolete, of the intermediate and posterior short but distinct), &c., we think best sepa- 
rated from Jsicerdes; the tarsi are variable in structure, and, except in H. longitarsis, 
short as in Isicerdes. The species are of similar habits to Isicerdes, and found by 
beating the branches or the still attached leaves of fallen trees. 
Some allied forms, perhaps not generically distinct, are found in Java. 
1. Hesiodus longitarsis. (Tab. VI. fig. 7, 3.) 
Oblong ovate, very convex, bright brassy sncous, often with a purplish or greenish tinge, shining. Head finely, 
shallowly, and sparingly punctured ; prothorax transverse, convex, scarcely wider behind than in front, 
* Tsicerdes attenuatus. 
Closely allied to I. funedris, and differing as follows :—The head less distinctly impressed on each side in front ; 
the thorax slightly narrowed anteriorly, the lateral margins more distinctly crenulate, and more closely 
and distinctly punctured ; the elytra comparatively shorter, more coarsely punctate-striate (the punctures 
longer and coarser and not so close together) ; prosternum horizontal, impressed oa each side within, the 
apex produced into a short broad tubercle, rugulose ; mesosternum raised on each side anteriorly, concave 
within. 
Length 8 millim.
