and everywhere closely punctured, except on the abdomen and 
antenne ; elytra with a coppery tint at the sides, the apices sub- 
truncate, with the outer angle not produced but rather slightly 
rounded ; abdomen luteous, impunctate ; femora bright green ; 
tibiz and tarsi black; antennz black, the scape with a slight tint 
of green. 
Length 5 lines. 
Closely allied. to an undescribed species known in collections 
as Chrysoprasis pubescens, but differing essentially in the form of 
the apices of the elytra and in the short stiff pubescence.

Caput breve, antice paulo productum., Antenne ¢ corpore 
fere duplo longiores, serrate; ¢ breviuscule, 1 1-articulatz ; 
scapo subpyriformi; articulo tertio vix scapo longiore, apice 
paulo dilatato; czteris brevioribus et bilateraliter dilatatis. 
Prothorax levigatus, utrinque pone medium angulato-den- 
tatus, postice fortiter constrictus. Scutellum angusté trian- 
gulare. £lytra subtrigonata, humeris prominulis, rotundatis. 
Pedes mediocres, antici breviores; femora clavata. Pro- 
sternum elevatum, sub-latum. Mesosternum declive, in medio 
dentatum. 
In some of its characters this genus is intermediate between 
Lissonotus and Charinotes, differing from the former in the lateral 
prothoracic spine and declivous mesosternum, from the latter in 
its smooth prothorax and 11-jointed antennee—at least in the 
female—while from both it differs in its elongated muzzle. The 
only male in the collection has but ten joints to its antennz, the 
last or perhaps two last having been lost. In this and the 
allied genera forming the sub-family Trachyderine, the form of 
the scutellum appears to have a real generic value ; in this genus 
it has that of a long narrow triangle. ‘The species described 
below bears a marked general resemblance to Lissonotus corallinus, 
especially in its coloration,
