HOMALISPA. 7 
the outer disc sulcate, their interspaces thickened, here and there distinctly costate ; 
outer limb reflexed, its surface concave, impunctate. 
In coloration this species strongly resembles many species of Homalispa. 
HOMALISPA. 
Homalispa, Baly, Cat. Hispide, p. 33. 
The present genus, apart from the structural differences of the mouth and antenne, 
may be known from Cephaloleia by the broader and more ovate form. With the excep- 
tion of the two described here the species inhabit the warmer parts of South America ; 
about a dozen species are known. 
1. Homalispa variabilis. (Tab. I. fig. 9.) 
Anguste oblongo-ovata, depressa, nitida; subtus nigra, pectoris medio nigro-piceo, thorace inferiori capiteque 
flavis; supra flava, antennis, capitis vertice scutelloque nigris; thorace levi, utrinque late excavato, vitta 
lata discoidali nigra ; elytris oblongis, distincte punctato-striatis, dimidio postico vittaque late suturali nigris, 
Var. A. Elytris flavis, vitta suturali pone medium obsoleta. 
Long. 23 lin. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Lower face excavated, concave ; vertex impressed with a few fine punctures. Antenne 
more than half the length of the body, filiform, very slightly attenuated at the base and 
apex; joints cylindrical, the second half the length of the basal one, the third as long 
again as the second. Thorax twice as broad as long at the base; sides very oblique, 
quickly converging from base to apex, straight behind the middle, slightly rounded 
anteriorly, apical angle produced, subacute, the basal one very acute; basal margin 
broadly concave, emarginate on either side, its medial portion very obtusely rounded 
and slightly reflexed; upper surface smooth and shining, remotely impressed with very 
fine punctures, only visible under a strong lens ; medial disc covered with a broad black 
vitta, which extends from base to apex; surface between this discoidal vitta and the 
lateral margin excavated, the lateral margin itself reflexed. lytra rather broader than 
the base of the thorax; sides straight, nearly parallel, apical margin (conjointly) 
obtusely rounded; the outer border very finely serrulate, serratures distant on the 
sides, closer at the apex; each elytron with eleven rows of distinct punctures, the first 
row short; outer striz subsulcate, their interspaces slightly convex. 
This species, of which I have seen five specimens, all collected by Mr. Champion, is 
very variable in pattern, and in the extent of the black coloration of the elytra. 
2. Homalispa limbifera. 
Late ovata, depressa, flava, nitida; scutello antennisque nigris, abdomine pallide piceo; thorace levi, ad latera 
sparse foveolato-punctato, disco plaga magna nigra, cuneiformi, a basi ad apicem producta instructo; 
elytris sat fortiter punctato-striatis ; piceo-nigris, limbo exteriori late flavo. 
Long. 2 lin.
