ALLECULA. 415 
and somewhat abruptly converging in front, the hind angles sharply rectangular, the basal fovese scarcely 
indicated, the surface unimpressed, and closely, coarsely, and equally punctured; scutellum sparsely 
punctured ; elytra rather long, a little rounded at the sides, with coarsely but not closely punctured 
very shallow strie, the strie becoming much deeper and more finely punctured towards the apex, the 
interstices feebly convex and sparsely and finely punctured, the punctures distinctly coarser towards the 
apex; beneath closely and somewhat coarsely punctured, the metasternum flat and almost unimpressed in 
the middle, the mesosternum convex and rather abruptly declivous in front ; legs brownish-piceous. 
Length 123-14 millim.; breadth 54 millim. ( 9.) 
Hab. Nicaraeua, Chontales (Belt). 
Two female examples. The broadly truncate mandibles, very broad, strongly trans- 
verse, and coarsely punctured thorax, broad and oblong ovate shape, and other 
characters mentioned above, will enable this insect to be easily identified. 
2. Tarsi feebly lobed beneath; upper surface more depressed ; elytra very shallowly 
and very finely punctate-striate. 
8. Allecula depressa, (Tab. XIX. figg. 1, 1a, ¢.) 
Elongate, rather depressed, obscure reddish-brown or brownish-piceous, slightly shining, thickly clothed with 
short pubescence. Head closely, irregularly, and rather finely punctured, a space on the middle of the 
vertex smoother; eyes comparatively large, and moderately widely separated; antenne ferruginous ; 
prothorax transverse, small, narrow, feebly transversely convex, the sides almost straight or very slightly 
narrowing behind and narrowed and a little rounded in front, the hind angles rather obtuse, the disc 
shallowly but somewhat broadly canaliculate, and transversely flattened before the base and apex, the 
basal fovese scarcely indicated, the surface finely (but deeply), irregularly, and rather sparsely punctured ; 
scutellum sparsely punctured ; elytra long, depressed on the disc, subparallel in their basal half, much 
broader than the prothorax, with very fine shallow striz, the strie with moderately fine and closely placed 
punctures, the interstices almost flat, very feebly convex towards the apex, and each with about two rows 
of fine punctures; beneath finely and sparsely punctured, the metasternum very closely and finely so 
in the middle behind in the male; legs slender, fusco-ferruginous. 
¢g. Anterior tibiz triangularly widened on the inner side about the middle. The lateral lobes of the last 
ventral segment broad at the base, narrow and slender outwardly, abruptly curved inwards about the 
middle, the apices blunt and almost meeting; the central sheath gradually narrowing, the apex slightly 
rounded, the basal part of the apical portion roughened and slightly setose on each side. (Fig. 1 a.) 
Length 93-103 millim.; breadth 33-33 millim. (¢.) 
Hab. Mexico (coll. F. Bates), Capulalpam (Sa//é). 
Four male examples. Labelled Allecula(?) mexicana, Dej., in Mr. F. Bates’s 
collection. 
9, Allecula opacipennis. (Tab. XIX. fig. 2.) 
Moderately elongate, rather depressed, piceous-brown, rather dull, the elytra opaque, thickly clothed with short 
pubescence. Head closely punctured, a space on the middle of the vertex smoother; prothorax trans- 
verse, small, narrow, feebly transversely convex, the sides slightly rounded, widest at the middle, and 
narrowing almost as much behind as in front, the hind angles very obtuse, the disc shallowly but rather 
proadly canaliculate and transversely flattened before the base and apex, the basal fovex small and shallow, 
the surface finely (but deeply) and rather closely punctured ; scutellum finely and somewhat closely punc- 
tured ; elytra moderately long, depressed on the disc, much broader than the prothorax, subparallel in their
