HEGEMONA. | 271 
punctured and not crenulated, the fifth interstice forming a strong pointed tooth a little 
before reaching the apex. In colour the head and thorax blackish-bronze, almost dull, 
the elytra of a browner bronze, more shining, and with a very slight cupreous tint. The 
specimen described is, no doubt, a female.

Hegemona compressus, Allard, Mittheil. der schweiz. ent. Ges. v. pp. 61, 254°. 
Hab. Muxico! (coll. Oberthiir, ex coll. Mniszech) ; Guaremaua (coll. Stuttgart Mus.), 
Lanquin (Champion). 
The type of this species, kindly lent me by M. Réné Oberthiir, agrees well with a 
male example captured by myself at Lanquin, and a second in the Stuttgart Museum. 
In this species the prosternum is subhorizontal, strongly acuminately produced, and 
longitudinally excavate on each side between the coxe. ‘The example from Lanquin is 
figured. 
7. Hegemona lineatus. (Tab. XI. fig. 23, ¢.) 
Bronze-black, the head and prothorax rather dull, the elytra shining. Head very minutely, shallowly, and 
sparingly punctured, broadly flattened and excavate anteriorly, the epistoma separated by a fine groove 
(deeply impressed posteriorly, shallowly so at the sides) ; prothorax subquadrate, nearly as long as broad 
in the male, shorter in the female, very gradually narrowing from the base, the sides almost straight, the 
hind angles subrectangular, the anterior angles produced in front, rounded, and comparatively very promi- 
nent, the disc sometimes with a very shallow fine impressed line, the surface finely, shallowly, and some- 
what closely punctured; elytra long, rather narrow, compressed and but little rounded at the sides, 
strongly gibbous, a little wider than the prothorax at the base, the stris very finely and shallowly punc- 
tured on the disc, much more coarsely so at the sides, the interstices strongly convex (still more strongly so 
posteriorly), almost smooth, alternately coloured metallic green and purplish-cupreous, and the first, second, 
and fifth usually confluent at the apex in both sexes, the apices somewhat obtuse ; beneath bronze-black, 
shining, almost smooth ; prosternum horizontal, strongly acuminately produced, smooth, its anterior face 
concave within and declivous, the apex rounded off and not tuberculiform. 
Length 17-20 millim.; breadth 7-9 millim. (d 2 .) 
Hab. Brivish Honpvuras, Belize (Blancaneaux); Guatemata (Sallé, coll. Brit. and 
Stuttgart Museums), San Juan and Panima in Vera Paz (Champion). 
Numerous examples. This vividly-coloured insect is nearest allied to HH. compressus, 
from which it may be known by its duller head and thorax, the latter much more shal- 
lowly and finely punctured, the elytra rather duller and shorter and less compressed at 
the sides, the interstices much more convex, the prosternum smoother, &c. The known 
localities for this species are all on the Atlantic slope. 
8. Hegemona niger. (Tab. XII. fig. 2, 4.) 
Black, slightly shining. Head very finely and sparingly punctured, the epistoma comparatively short and 
separated by a moderately deep groove, the vertex with a shallow semicircular impressed line extending 
on each side anteriorly to the inner margin of the eye; prothorax transverse, the sides moderately 
rounded and scarcely more narrowed anteriorly than at the base, the hind angles subrectangular, the
