210 HETEROMERA. 
1. Lelegeis eneipennis. (Tab. IX. fig. 23, 3.) 
Oblong ovate, depressed, subparallel, brownish testaceous, shining. Head transversely impressed in front, 
finely and sparingly punctured ; prothorax strongly transverse, the sides slightly rounded and gradually 
converging from the base, the apex deeply arcuate emarginate, the anterior angles rounded, the base 
deeply bisinuate, the surface sparingly and finely (the sides rather more coarsely) punctured ; elytra finely 
punctate-striate (the punctures shallow and rather closely placed), the interstices flat and very minutely 
and sparingly punctured, darker in colour than the prothorax, brown, with a distinct eneous tinge ; legs 
and antenne testaceous; beneath shining, almost smooth, the ventral surface sparingly punctured, along 
the sides much more coarsely punctured, the first segment also longitudinally wrinkled. 
Length 6 millim. (¢.) 
Hab. Mexico, Cordova (Sal/é). 
One example, in somewhat immature condition. 
COSMONOTA. 
Cosmonota, Blanchard, Hist. Nat. des Ins. ii. p. 30 (1845) ; Lacordaire, Gen. Col. v. p. 305. 
Some few species of this genus are known from Tropical America; one has been 
described from Mexico, and we now add another from Nicaragua. 
Cosmonota, as Lacordaire remarks, is very near Platydema, and separated from that 
genus more by general facies and system of coloration than by salient characters. 
These insects are of the same habits as Platydema. 
1. Cosmonota nigripes. (Tab. IX. fig. 20.) 
Cosmonota nigripes, Chevr. Petites Nouv. Ent. ii. p. 173°. 
Hab. Mexico, Cordova (Sallé1, Hoge); British Honpuras, Belize, R. Sarstoon 
(Blancaneaux) ; GUATEMALA, Zapote, El Tumbador (Champion) ; Nicaragua, Chontales 
(Belt, Janson). 
A large species, with the upper surface red and shining, the tibia, tarsi and antenne 
(the two basal joints excepted) black. 
A totally different insect, from Brazil, in Mr. F. Bates’s collection is labelled (appa- 
rently in Chevrolat’s handwriting) “ C. nigripes, Chevr., type”; this species, however, 
does not agree with either the published description or locality. An example from 
Chontales is figured. 
2. Cosmonota pubescens. (Tab. IX. fig. 21.) 
Obovate, rather convex, black, shining. Head long, the epistoma long, projecting beyond the sides of the front, 
and sharply defined, coarsely (the epistoma more closely and rather more finely) punctured, the intra- 
ocular space shallowly impressed in the middle; labrum and mouth-parts red; antenne long, setose, 
joints 7-10 subtriangular, the eleventh joint much longer than the tenth and bluntly rounded at the apex, 
the two basal joints, and the outer half of the apical one, red, the rest piceous; prothorax transversely 
convex, broader than long, narrowing a little anteriorly, the sides slightly rounded in the middle, and 
distinctly sinuate before the base, the apex broadly but not deeply arcuate emarginate, the anterior angles 
rounded, the base strongly bisinuate and with an oblique fovea on each side, the posterior angles promi- 
nent but not acute, the surface finely, regularly, and sparingly punctured, and with two or three shallow
