COPTOCYCLA. 197 
26. Coptocycla gibbifera, (Tab. X. figg. 23, ¢; 23a, profile of ditto; 
24, 2, var.) 
3. Rounded-triangular, very broad, convex, shining, flavo-testaceous ; the prothorax with a transverse black, 
castaneous, or ferruginous patch of variable size on the basal part of the disc—excised on either side and 
produced in the middle in front, and with an interrupted testaceous median line, or divided down the 
middle, so as to form two sinuous stripes; the scutellum black with a testaceous line down the middle, 
or entirely testaceous; the elytra with the disc black, castaneons, or rufo-testaceous, and with a broad 
similarly-coloured ramus extending across the margins to the humeri, the suture anteriorly and some 
irregular markings and spots on the disc flavo-testaceous ; the antenn flavo-testaceous, with the apical 
Joint, and sometimes the tenth also, black ; the legs and under surface flavo-testaceous. Antenne very 
elongate and slender, filiform, joint 3 nearly twice as long as 2. Prothorax about twice as broad as long, 
with the base deeply sinuate on either side of the broad median lobe and obliquely truncate laterally ; 
the disc smooth, transversely depressed in the middle at the base; the margins very broadly expanded 
laterally and in front, subhyaline, and reticulate. Elytra nearly one-half wider than, and about three 
times as long as, the prothorax, very deeply sinuate-emarginate at the base, with the humeri rather 
sharp and greatly produced anteriorly, reaching to a little beyond the middle of the prothorax; the disc 
longitudinally convex, abruptly transversely gibbous below the base, with rows of coarse, subapproximate 
punctures, which towards the suture are placed in rather deep strie, the interstices smooth, flat at the 
sides, convex towards the suture, and here and there connected by transverse or oblique feebly raised 
spaces ; the margins very broadly expanded, gradually becoming narrower towards the apex, smooth and 
reticulate, subhyaline from a little below the base, broadly concave before the middle and obliquely 
excavate within the humeral angle. Claws simple. 
9. The antenne shorter ; the prothorax with the base more rounded towards the sides; the humeri more 
divergent and slightly sinuate externally. 
Var, The antenne and prothorax entirely flavo-testaceous ; the elytra flavo-testaceous, faintly variegated with 
darker markings, the basal ramus distinct but not reaching the humerus. 
Length 73-8, breadth 64-74 millim.

Sixteen examples. Following Boheman’s arrangement, C. gibbifera should be 
placed next the Brazilian C. vigens, the only species of the genus described by him 
with gibbous elytra and strongly produced humeri. ‘The present species closely 
resembles C. asperata, Boh.; but it has the humeri more produced in front (especially 
in the male), the disc of the elytra smoother posteriorly, and the base of the prothorax 
more deeply sinuate on either side of the median lobe. C. gibbifera also approaches 
those species included in Psalidonota by Boheman. We figure a male from Bugaba, 
and a pallid female from Chontales.

‘“‘ Rotundata, modice convexa, nitida, supra lete castanea, margine toto flavo-hyalino, reticulato; subtus

dilutiore ; elytris mediocriter, crebre striato-punctatis, singulo in disco exteriore linea nigra, a basi ad 
medium extensa; margine late explanato; humeris antrorsum valde prominulis, acutis.—Long. 83, 
lat. 73 millim.”
