This is a common insect in Central America. It varies greatly in size, and also in 
the colour of the antenne, and of the under surface, the elytral markings, too, are. 
sometimes obliterated. With the types of Boheman’s insects before me, I am unable 
to distinguish more than one variable species. C. meticulosa was based upon a 
discoloured male example of C. erratica, with the apical five joints of the antenne 
apparently (?) infuscate ; the characteristic transverse ferruginous spot on the suture 
before the middle is very distinct in the type, though it is not mentioned by Boheman. 
C. varicornis (the type of which is contained in the British Museum) has the elytral 
markings obliterated and the abdomen entirely testaceous, characters of no importance 
when a long series of specimens is examined; it has been received from a number of 
localities in company with C. erratica. The elytra usually have an indeterminate vitta 
on the outer part of the disc—extending from a little in front of the humeral callus to 
beyond the middle and then curving inwards to the suture,—and a common transverse 
spot on the suture before the middle, ferruginous or fuscous, the rather coarse, 
scattered, subserially arranged punctures being similarly coloured. The antenne are 
testaceous, and usually have the ninth and tenth joints, and sometimes the eighth also, 
infuscate ; but in some specimens (from Chiriqui) they are almost entirely testaceous, 
and in others the apical joint is infuscate, except at the tip; the third joint is a little 
longer than the second, and shorter than the fourth. Several of the Chiriqui examples 
are unusually large, others, again, from Teapa are small, the species varying considerably 
in this respect. In some specimens the elytra are subseriately punctured to the apex ; 
the transverse sutural spot is nearly always distinct, even in the variety varicornis. 
We figure a male example from Tuxtla. 
79. Coptocycla angularis. (Tab. XII. fig. 15, ¢.) 
Rounded-triangular, moderately convex, flavo-testaceous; the prothorax with an indistinct oblong dilute 
fuscous or castaneous patch on the middle of the disc behind, this being excised in front ; the elytra with 
a common transverse subquadrate patch across the suture before, and an irregular fascia beyond the 
middle, some irregular markings, the punctures, and a broad ramus on the margin at the base extending 
from the disc outwards, dilute castaneous or fuscous; the antenne flavo-testaceous, with the ninth and 
tenth joints more or less infuscate; the legs flavo-testaceous; the body beneath black, marked with ' 
yellow at the sides, the abdomen with the sides and apex broadly flavo-testaceous. Antenne moderately 
long, slender, the apical five joints a little thickened, joint 3 short, not longer than 2. Prothorax nearly 
twice as broad as long, rather feebly sinuate at the base on either side of. the median lobe, broadly 
expanded at the sides and in front, smooth ; the disc obliquely grooved on either side of the median lobe 
behind; the margins hyaline and reticulate. Elytra very much wider than, and about three times as
