162 PHYTOPHAGA. 
Apparently not uncommon in Western Mexico. The prothorax is deeply foveate on 
either side of the middle at the base, a character not mentioned by Boheman; some 
specimens have a brownish 4-shaped mark on either side of the disc, the two marks 
often connected in front, but this may be partly due to discoloration. A specimen 
from Ventanas is figured. 
2. Batonota yucatana. (Tab. VIII. figg. 3; 34, profile.) 
Obtusely triangular, the prothorax shining, the elytra subopaque; castaneous or yellowish castaneous ; the 
antenn piceous, with the five basal joints testaceous; the legs and the body beneath testaceous or rufo- 
testaceous, the tibise sometimes stained with piceous above. Head canaliculate and punctured between 
the eyes; antenne rather short and slender, not extending beyond the humeri, joints 1-5 almost smooth, 
shining, 2 and 3 very short, subequal, 4 and 5 twice as long as 3, equal, 6-11 densely punctured and 
opaque, 6 barely the length of 4 and 5 united, 6-10 subequal in length, 11 longer than 10. Prothorax 
strongly transverse, feebly arcuate-emarginate in front (truncate if viewed from above), the sides very 
rapidly and abruptly converging from the base, a little rounded behind, the base deeply emarginate on 
either side of the broad emarginate median lobe and thence to the hind angles very obliquely truncate ; 
the disc transversely convex, hollowed on either side in front (appearing longitudinally raised in the middle 
at the apex), and with a shallow fovea on either side of the median lobe at the base; the margins feebly 
expanded, the exterior edge slightly reflexed ; the entire surface very sparsely, finely punctate. Scutellum 
flat, almost smooth. Elytra at the base one and a half times the width of the prothorax, obtusely triangular, 
bluntly rounded at the apex, narrowing from the base, the sides sinuate behind the humeri; armed with 
a very long, erect, compressed, obtuse spine before the middle; the disc very coarsely, subseriately 
punctured, the punctures not very closely placed, and with indications of two or three irregular coste, 
the interstices with very minute scattered punctures; the margins narrowly expanded, with a series of 
very coarse, deep, transverse foveee extending from the middle to the apex, almost smooth in front; the 
humeri moderately prominent, rounded exteriorly and in front, and with an oblique carina extending 
inwards to the humeral callus. Beneath very shining, almost smooth, the apex of each ventral segment 
sparsely punctured and pubescent; prosternum flat and almost unimpressed behind, more or less foveate 
in the middle in front. 
Length 64-74, breadth 54-6 millim. 
Hab. Mexico, Temax in North Yucatan (Gawmer). 
Numerous examples. This small species is allied to B. aurita, Boh.; but it is much 
smaller and darker than that insect, the prothorax is more transverse, and the coarse 
punctures on the elytra are not nearly so numerous, the interstices flatter and sub- 
opaque. ‘The punctures on the elytral interstices are only visible under a strong lens. 
ii, Elytra with a compressed, acute or triangular, transverse elevation before the middle. 
3. Batonota nodosa. (Tab. VIII. figg. 4; 4, profile.) 
Batonota nodosa, Boh. Monogr. Cassid. 11. p. 160*, and iv. p. 2377; Cat. Col. Ins. Brit. Mus. ix. 
p. 94°. 
Hab. Panama, David, Caldera, Tolé (Champion).—Conomsia 1-3, 
Not uncommon in Chiriqui, where it has been found on the calabash-tree, Crescentia 
cujete. I have compared our specimens with one from Colombia in the British 
Museum, named by Boheman himself.
