164 _ PHYTOPHAGA. 
iii. Elytra with a compressed, obtuse, transverse elevation before the middle. 
8. Batonota eremita. 
Batonota eremita, Boh. Monogr. Cassid. iv. p.'240°. 
Hab. Costa Rica (coll. Dohrn 1). 
Apparently exceedingly close to, and perhaps not distinct from, B. insidiosa, from 
which it seems to differ in having the elytra marked with smaller and more numerous. 
spots, and the elevation obtuse (instead of subacuminate, as in B. insidiosa). 
9. Batonota biplagiata. (Tab. VIII figg. 10; 104, profile; 10, antenna.) 
Subtriangular, broad ; the upper surface opaque, clothed with a very short, fine, scattered, ashy pubescence ;: 
the head, antennz, prothorax, scutellum, legs, and the body beneath black; the elytra green or bluish- 
green, each with a very large dilute sanguineous or rufo-testaceous patch occupying fully half the entire 
surface—extending from the base to far beyond the middle and almost surrounding the ante-median 
elevation, and laterally (from a little behind the humeral carina to beyond the middle) to very near the 
outer margin. Head sparsely punctured and canaliculate between the eyes; antenne extending to far 
beyond the humeri, joints 1-5 almost smooth, shining, 2 and 3 very short, equal, 4 and 5 longer, 5 longer 
than 4, 6-11 densely punctured and opaque, 6 elongate, as long as 3-5 united, 6-10 equal in length, 
11 much longer than 10. Prothorax strongly transverse, broadly and feebly arcuate-emarginate in front, 
the sides rapidly arcuately converging from the base, the base deeply emarginate on either side of the 
broad slightly emarginate or truncate median lobe and thence to the hind angles very obliquely truncate ;. 
the disc obsoletely longitudinally carinate in the middle in front; the margins concave, moderately 
expanded ; the entire surface thickly, very minutely punctate. Scutellum foveate in the middle. Elytra 
at the base nearly twice as wide as the prothorax, subtriangular, conjointly rounded at the apex, narrowing 
from the base, with a strongly compressed, transverse, obtuse elevation before the middle ; the disc coarsely,. 
closely, subseriately punctured, and with two irregular carine near the suture and one about the middle, 
the punctures on the apical portion much finer and shallower ; the margins very broadly expanded, thickly, 
finely, confusedly punctured, and separated from the disc by a row of very coarse, deep impressions; the 
humeri prominent but obtuse, reflexed and slightly oblique in front, and with an oblique carina extending 
inwards to the prominent humeral callus. Beneath shining, sparsely pubescent, the apex of each ventral 
segment fringed with longer hairs; prosternum very deeply sulcate. 
Length 14-143, breadth 13-134 millim. 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
Two examples, from the western slope of the Volcano. Allied to B. rufo-ornata, 
B. sexplagiata, &c.; but with a more obtuse elytral elevation (not at all acuminate, if 
viewed from behind), the elytra each with a very large dilute sanguineous or rufo- 
testaceous patch occupying half the entire surface. 
CISTUDINELLA. 
Head deeply withdrawn beneath the prothorax ; the latter broadly rounded or truncate anteriorly, the base 
broadly arcuate-emarginate on either side and with an obtuse median lobe, the hind angles sharp and 
produced backwards, the anterior angles obliterated; the scutellum small, strongly transverse; the elytra 
forming almost a continuous outline with the prothorax ; prosternum trnncated in front, proudced and 
very broadly, triangularly dilated behind the coxe, and received by the deeply excavate V-shaped
