142 : HETEROMERA. 
punctured, and with two fine rather sharp coste on the disc and one at the sides, the inner one not 
reaching the apex, the suture also distinctly raised, the apices obtuse and divergent; beneath closely 
and finely punctured and pubescent, rather shining, piceous or piceous-brown with an ‘neous lustre, the 
sides of the meso- and metasternum more or less violaceous, the head and prothorax brilliantly so, the 
epipleure coppery or violaceous ; legs slender, black or brownish, the coxe pale testaceous, the penultimate 
joint of the tarsi tomentose beneath. 
3. Fifth ventral segment rather deeply emarginate ; the sixth with the lateral lobes projecting considerably 
beyond the fifth and hairy at the apex. 
Length 7-93 millim. (¢ 2.) 
Hab. Guatemaua, Purula, Sabo, and Sinanja in Vera Paz (Champion). 
Found in profusion by myself in the humid forest-region of the Atlantic slope at 
elevations of from 1500 to 4000 feet. The insect superficially resembles Calleros sinanje, 
Gorh., a species of Lycide inhabiting the same district, and, like it, is found resting 
upon leaves in the moist forest. The thorax is much more coarsely and more roughly 
punctured than the head and is of a uniform crimson- or coppery-red colour. The 
elytra in certain lights appear purplish or violaceous, and their colour is obscured 
by the brownish pubescence. A female example is figured. 
20. Sisenes mimetes. (Tab. VI. fig. 25, 9 .) 
Allied to S. lyciformis, and differing as follows :—The head closely and rather coarsely punctured, with the 
sides piceous, dark bronze, or blackish-violaceous, a longitudinal space in the middle behind (narrowing 
anteriorly and becoming broader towards the base) reddish or flavous; the prothorax yellowish- or brick- 
red, with the sides in front narrowly violaceous, the surface densely and rather coarsely punctured ; the 
elytra black, blackish-violaceous, or blackish-brown, with the sides to about the middle (very broadly at 
the base and rapidly becoming more narrowly so) ochraceous ; the rest as in S. lyciformis. 
Length 63-9 millim. (¢ @.) 
Hab. Mexico, Cordova (Sallé), Jalapa (Hége). 
Five examples. The very much finer and less rough punctuation of the thorax and 
the differently-coloured upper surface distinguish this species at a glance from S. /yci- 
formis, with which it agrees closely in size, shape, and sculpture. The antenne have 
joints 83-5 very much thickened. This species, like many others of widely different 
families, bears a remarkable resemblance to certain Lycide inhabiting the same dis- 
tricts, a similar system of coloration and general facies—and, to a certain extent, form 
of antenne—existing in various Central-American Longicornia, Hispide, Galerucide, 
Lagriide, and Meloide. 
21. Sisenes personatus. (Tab. VI. fig. 26, ¢ .) 
Elongate, thickly pubescent, opaque; the head black, a narrow longitudinal space down the middle behind 
ochraceous, the sides of the front and the mandibles (the tips excepted) flavous, the labrum black ; the 
prothorax black, with a broad longitudinal band down the middle, and the sides narrowly at the’ base, 
ochraceous; the scutellum ochraceous ; the elytra black, with a short lateral stripe at the base (starting 
from the shoulder and gradually narrowing behind) ochraceous. Head about as wide as the prothorax, 
densely and rather finely punctured, the eyes small ; antenne ( @ ) black, rather long, tapering outwardly, 
joint 2 very short, joints 3-5 very much stouter than the others ; prothorax comparatively large, broader 
than long, the sides a little rounded anteriorly and very slightly sinuate behind, the hind angles some-
