A common insect in Central America, ranging from the Mexican State of Durango 
right down to Panama, and probably extending into the northern parts of South 
America. 0. leprosa is doubtfully recorded by Boheman ® as from Brazil. 
The rows of coarse punctures on the elytra are interrupted beyond the middle by an 
oblique, smooth, flavous space, which becomes much wider externally, and is much 
more raised in some specimens than in others. ‘The elytra have an abrupt, strongly 
raised, transverse elevation across the suture below the base, this and a spot on the 
humeral callus being usually sanguineous or dilute castaneous. ‘The antenne are very 
elongate and filiform, the third joint nearly three times as long as the second. 
We figure a specimen from Chontales, agreeing perfectly with the (somewhat 
discoloured) type. | 
5. Coptocycla dorsoplagiata, (Tab. X. figg. 5,3; 5a, profile; 5, antenna.) 
Rotundate, convex, dilute flavo-testaceous, shining; the elytra flavous, with the suture narrowly, a transverse 
spot at the summit of the post-basal elevation, the punctures on a broad space between it and the apex 
of the disc (widened anteriorly and posteriorly), and the fourth to the sixth rows of punctures to about 
one third from the base, castaneous or dilute castaneous; the antennee testaceous, with the apical three 
joints partly or entirely black; the legs and under surface testaceous. Antenne very elongate, slender, 
filiform, joints 8-10 elongate and subequal, 2 more than twice as long as 2. Prothorax subtrapezoidal, 
the base deeply sinuate on either side of broad median lobe and abruptly and obliquely truncated 
laterally, the apex rounded; broadly expanded, reticulate, and subhyaline in front and at the sides; the 
surface almost smooth, the disc obsoletely canaliculate. Elytra very much wider than, and about three 
times as long as, the prothorax, conjointly rounded at the apex in the female, more obtuse behind in the 
male, very deeply sinuate-emarginate at the base, with rounded prominent humeri; the disc convex, 
transversely gibbous below the base, and excavate on either side of the suture before this, with rows of 
very coarse deep punctures, which are interrupted before the middle by a S-shaped smooth elevation 
extending from the post-basal elevation outwards, the punctures themselves crowded upon a broad space 
between this and the apex and remote upon the rest of the surface, the interstices smooth and uneven; 
the margins exceedingly broadly expanded, becoming narrow at the apex, smooth, reticulate, and sub- 
hyaline, separated from the disc by a row of deep punctures, and transversely plicate internally a little 
before the middle. Claws simple. 
Length 10-104, breadth 93-104 millim. 
Hab. Mexico (Mus. Brit.); Guaremata, Chacoj in Vera Paz, Zapote (Champion) ; 
Nicaragua, Chontales (Belt); Costa Rica (Van Patten). 
Six examples. This species is allied to the Cuban C. dorsopunctata (Boh.) (and the 
Mexican specimen referred to that species by Boheman no doubt belongs here); but 
differs constantly from it in having the crowded castaneous punctures limited to a 
narrower space on the elytra, the sparsely punctured flavous lateral spaces being much 
more extended. It differs from C. leprosa in having the elytra less gibbous, and the 
rows of punctures not interrupted beyond the middle by a transverse, smooth, irregular 
fascia ; and from C. contempta by the less gibbous elytra and smooth margins.
