208 HETEROMERA. 
This species varies somewhat in the extent of the black markings on the thorax and 
elytra. An example from Jalapa is figured. 
7. Liodema flavo-variegatum. (Tab. IX. fig. 18.) 
Broad oval, convex, testaceous, slightly shining. Head black, the frontal half more or less testaceous, finely, 
shallowly, and somewhat closely punctured ; eyes strongly oblique, not widely separated ; antenn serrate 
from the fourth joint, joints 7-10 and the basal half of the eleventh slightly darker; prothorax strongly 
transverse, the sides rounded in a line with the elytra, the base strongly bisinuate, the surface very finely 
and somewhat closely punctured, a large black mark (angular on its outer edge and extending to the 
base) in the middle of the disc, and a broad crescent-shaped black mark on either side; elytra with 
regular rows of fine indistinct punctures, the interstices punctured like the prothorax, marked with black, 
thus—the base narrowly, from whence proceed three short longitudinal streaks (two close together about 
the middle, and one near the shoulder), a rather broad angulated band (reaching the lateral margin and 
confluent at the suture) about the middle, and a narrower subangulate band (not reaching the lateral 
margin) before the apex, the suture also black from the subapical band to the base; legs testaceous ; 
beneath reddish brown, shining. 
Length 3-37 millim. 
Hab. Panama, Bugaba (Champion). 
Four examples. A small, broad ovate, convex species allied to L. serricorne, but 
only half the size, the elytra differently marked, &c. 
STENOSCAPHA. 
Stenoscapha, F. Bates, Ent. Monthly Mag. ix. p. 237 (1873). 
This genus was described upon a single species (S. ¢édialis) from the Amazons; we 
now add another from Mexico. | 
1. Stenoscapha jalapensis. (Tab. IX. fig. 19.) 
Narrowly ovate, moderately convex, unicolorous reddish brown, slightly shining. Head extremely finely and 
shallowly punctured, the epistoma sharply defined by a semicircular impressed line; eyes small, distant, 
slightly oblique; antenne testaceous, joints 5-10 triangular; prothorax transverse, the sides scarcely 
rounded, and rapidly narrowing from the base, the surface almost smooth ; elytra the width of the pro- 
thorax at the base, gradually rounded at the sides, very sparingly and almost imperceptibly punctured, 
with scarcely any indication of striw; legs and palpi testaceous. 
Length 33 millim. 
Hab. Mexico, Jalapa (Hége). 
One example. The unicolorous and almost impunctate upper surface and somewhat 
differently formed head and thorax will separate this species from S&. tibialis. 
PANIASIS. 
Mentum transverse, small ; last joint of the maxillary palpi subtriangular; antenne long, passing some dis- 
tance beyond the base of the prothorax, rather slender, the third joint half as long again as the fourth 
joints 5-10 long and subtriangular and decreasing slightly in length, the eleventh joint the width of but 
much longer than the tenth, and bluntly rounded at the apex; head as in Platydema (P. diophthalmum,
