156 SEKEICOENIA. 



One example from Cerro Zunil and another from Volcan de Chiriqui agree with 

 var. 2, except that they appear broader and have a slight coppery-brown tint on the 

 thorax. 



5. Leiopleura viridifrons. 



Oblonga, convexa, nitida ; capite antice viridi ; thoracis disco convexo, punctulato, lateribus deplanatis, viri- 



dibus, margine antico cupreo, basi transversim sat profunde impressa ; elytris subtiliter punctulatis.

Hab. Panama, Volcan de Chiriqui 5000 feet {Champion). 



This species is very close to L. crassa ; but the thorax is a little broader, the elytra 

 are scarcely widened behind the middle, so that they are more gradually narrowed to 

 the apex, and the sculpture is finer. The head in front is golden-green, less convex 

 than in L. crassa, longitudinally impressed in the middle, finely rugose, and with some 

 distinct punctures. The antennae are brassy. The thorax has the margins more 

 broadly rugose, the rugose surface occupying almost one-third of the width. The elytra 

 have the surface less smooth, with fine striolse between the punctures. 



6. Leiopleura pulchra. (Tab. IX. fig. 4.) 



Oblonga, convexa, nigra, nitida ; capite tboraceque aureo-viridibus, hoc macula antice nigra ; elytris violaceo- 



nigris, fascia lata mediana apiceque aureo-viridibus.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



The head is almost smooth, but under the microscope is seen to be finely vermiculate- 

 striolate, with some distinct punctures scattered over the surface ; there is a longitu- 

 dinal impressed median line. The antennae are aeneous. The thorax is sculptured 

 somewhat in the same way as the head, but the punctures are moderately strong, not 

 very close together ; there is a little rugosity at the anterior angles ; the disc is not so 

 convex as in L. crassa, and the sides are not so impressed ; there is a transverse impres- 

 sion on each side of the base. The elytra are convex, narrowly margined, the surface 

 somewhat uneven, marked with rather large punctures, which are more numerous in 

 the basal half; the lateral subhumeral impression is well marked, but without distinct 

 limitations. 



7. Leiopleura puncticeps. 



Oblonga, convexa, nitida ; capite sat crebre punctato, aureo-viridi ; thorace punctato, medio fusco-nigro, late- 

 ribus late aureo-viridibus ; elytris violaceo-nigris, convexis, crebre punctatis, vitta juxta suturam postice 

 fascia mediana juncta, maculaque transversa ante apicem viridibus.
