ULEDA. 
Uleda, Castelnau, Hist. Nat. 11. p. 220. 
Mentum large, coarsely punctured, transversely oval, the sides produced laterally, pilose in the male, glabrous 
in the female ; ligula prominent, the anterior angles rounded, triangularly emarginate in front; palpi 
stout, the last joint of the maxillary pair securiform ; inner lobe of the maxille toothed at the apex ; 
labrum prominent, coarsely setose, separated from the epistoma by a more or less distinct membranous 
space; antennz stout, perfoliate, setose, widening outwards, rather short, not reaching to the base of the 
prothorax, the third joint scarcely longer though narrower than the fourth, the seventh to the tenth trans- 
verse, the eleventh almost twice as long as and rather broader than the tenth, and bluntly rounded at 
the apex; head short, broad, somewhat deflexed, deeply sunk into the prothorax; epistoma short, 
distinctly defined posteriorly by a transverse impressed line, broadly but feebly emarginate in front ; 
lateral margins of the front but little swollen; eyes rather large, convex, strongly transverse ; prothorax 
much broader than long, narrowing anteriorly, the lateral margins distinctly swollen and reflexed, the 
base strongly bisinuate and’ not margined ; scutellum large, scutiform ; elytra broad, a little broader than, 
and closely embracing, the prothorax, widest behind the middle, narrowly margined, the humeri rounded, 
regularly and deeply punctate-striate, sometimes with a scutellar stria ; tibice dilated outwardly, the two 
front pairs finely denticulated on their outer edge, in the male the anterior pair inwardly curved, and 
the inner apical angle broadly and obliquely produced and covered witb short fulvous hairs, and the 
intermediate ones also slightly produced at their inner apical angle (in U. diaperoides &c. the outer half 
broadly expanded), spurs strong ; tarsi stout, thickly clothed (the inner sides also of all the tibise towards 
their apices, sparingly) with long fulvous hairs beneath, the first joint of the posterior pair long, as long 
as the apical joint ; epipleure broad, abruptly terminating some distance before the apex of the elytra ; 
prosternum deflexed behind, the apex slightly produced; mesosternum short; intercoxal process broad, 
slightly rounded in front ; form convex, broad oval, short. 
This genus contains some few species, mostly undescribed, from Tropical South 
America, one of which has been found in Mexico by Truqui; Uloma (Uleda) 
diaperoides, Cast., from Brazil, also belongs to it. The broad ovate, short form, and 
characters given above are, in my opinion, sufficient to separate this genus from 
Uloma. I adopt the name Uleda, used by Castelnau for a section of Uloma containing 
U. diaperoides. Lacordaire (Gen. Col. v. p. 333) retains this species in Uloma. ‘The 
species here described is, however, more typical; in Mr. F. Bates’s collection the genus 
is separated from Uloma and labelled Melania? 
1. Uleda grossa. (Tab. VII. fig. 13, ¢; 134, labium, ?; 134, labium, 3; 
13 ¢, maxilla and maxillary palpus.) 
Broad ovate, short, convex, black, shining. Head finely and sparingly punctured; prothorax much broader 
than long, widest behind the middle, rounded at the sides, narrowing anteriorly, much broader at the 
base than in front, the angles obtuse, finely and rather closely punctured ; elytra broad, slightly rounded 
at the sides, widest some distance behind the middle, deeply and regularly punctate-striate (the punctures 
the interstices slightly convex and very finely and sparingly punctured; beneath 
placed close together), 
along the sides, the sides and base of the ventral surface with numerous 
shining, coarsely punctured
