116 HETEROMERA. 
the sides slightly rounded, feebly sinuate before the base, anterior angles rounded, hind angles subacute, 
the base strongly bisinuate, usually feebly impressed transversely before the base, finely, shallowly, 
and sparingly punctured; elytra strongly convex, rather long, slightly wider than the thorax, with 
regular rows of fine distant impressions placed upon shallow indistinct strie, interstices exceedingly finely 
and sparingly punctured ; legs black, rarely reddish brown; intermediate and posterior tarsi long and 
thin, basal joint of the latter longer than the two following joints united. 
Length 63-73 millim. (¢ 9.) 
Hab. Mexico, Cordova (Sallé), Jalapa (Hége); Nicaragua, Chontales (Belt). 
Not rare in Mexico; one example only from Nicaragua, An allied species is found 
in the Amazon region *. 
2. Hesiodus sordidus. 
Allied to H. longitarsis, and differing as follows :—Colour reddish brown, with a slight greenish tinge ; pro- 
thorax more closely and distinctly punctured ; elytra punctate-striate, the punctures fine and approximate, 
the interstices rather more distinctly punctured, scutellar stria distinct, the base straighter; tarsi shorter, 
the basal joint of the hinder pair about as long as the two following joints united. 
Length 6 millim. 
Hab. Mxxico, Cordova (Sallé).—Brazit, Ega (coll. F. Bates). 
One example from each locality. 
3. Hesiodus jansoni. 
Oblong ovate, strongly convex, black, shining. Head finely and rather closely punctured ; prothorax trans- 
verse, widest at the base, slightly narrowing anteriorly, the sides slightly rounded and very feebly sinuate 
before the base, feebly impressed transversely before the base, the base strongly bisinuate, distinctly, finely, 
and rather closely punctured; elytra a little wider than the thorax, finely and rather closely punctate- 
striate, the striz feebly impressed, interstices very finely and rather closely punctured, humeri distinct ; 
tarsi short, basal joint of the hinder pair the length of the two following joints united. 
Length 63-74 millim. (¢ @.) 
Hab. Nicarasva, Chontales (Janson). 
Several examples. Of the form of Jsicerdes occultus, but much smaller, the tibie 
not grooved on their outer edge, the elytra finely and shallowly punctate-striate. 
4, Hesiodus conspurcatus. 
Oblong ovate, convex, black, shining. Head closely and not very finely punctured, the epistoma smoother ; 
prothorax transverse, widest at the base, scarcely narrowing anteriorly, the sides slightly rounded before 
the middle and almost straight behind, hind angles rectangular, lateral margins slightly crenulate, base 
* Hesiodus brasiliensis. 
Allied to H. longitarsis ; prothorax a little wider anteriorly, more distinctly, less finely, and more closely 
punctured ; the elytra less finely punctate-striate, the punctures coarser and closer, the scutellar stria very 
distinct ; tarsi much stouter and shorter, the basal joint of the hinder pair as long as the two following 
joints united. 
Length 6 millim. 
Hab, Braz, Ega (coll. F. Bates). One example.
