LEIOPLEUEA. 155 



3. Leiopleura divisa. 



Oblongo-ovata, sat lata, depressa, nigra, nitida, capite antice obscure seneo-virescente ; thoracis disco punctato, 

 lateribus late subtilissime rugosis, virescentibus ; elytris nigro-purpurascentibus, subtiliter punctatis, 

 vermiculoso-striolatis, fasciis duabus sat latis ad suturam interruptis viridibus rugosis. 



Long. 1| lin. 



Hab. Panama, Volcan de Chiriqui 2500 feet {Champion). 



This species is very close to L. contigua ; but it is smaller, and has two bright 

 green rugose bands on each elytron — one a little before the middle, obliquely directed 

 upwards towards the scutellum, not reaching the suture ; the second near the apex, 

 similar but shorter. The basal joint of the antennae and part of the anterior surface 

 of the femora are brassy. The intermediate tibiae are subcylindrical and comparatively 

 straight. 



4. Leiopleura crassa. (Tab. IX. fig. 3.) 



Oblonga, convexa, nitida ; capite virescente ; tborace cseruleo, nitidis&imo, disco bene convexo, parce punctu- 

 lato, lateribus postice late deplanatis, basi transversim sat profunde impressa; elytris violaceo-cyaneis, 

 punctatis. 



Long, lf-lf lin. 



Hab. Panama, Bugaba {Champion). 



Var. 1. Capite tboraceque nigris. 



Hab. Panama, Bugaba 800 to 1500 feet {Champion). 



Var. 2. Tota nigra. 



Hab. Guatemala, Chacoj in Vera Paz, Las Mercedes 3000 feet, Cerro Zunil 4000 

 to 5000 feet {Champion) ; Panama, Volcan de Chiriqui 2500 to 6000 feet, Taboga I. 

 {Champion). , 



The head appears smooth, with some moderately large punctures scattered over the 

 surface ; but under the microscope some additional very fine punctures may be seen ; 

 there is a longitudinal impression in front. The thorax has a bluer tint than the 

 head ; it is not much narrowed in front, broadest at the posterior angles, which are 

 very acute and directed backwards ; the disc has a few punctures ; the sides are flat- 

 tened, narrowly in front, broadly at the posterior angles ; the lateral margins have a 

 narrow vermiculate-striolate border. The elytra are convex, declivous posteriorly ; at 

 the base as broad as the thorax, gradually but not much widened to about three-fifths 

 their length, and obliquely narrowed to the apex; dark violet-blue ; distinctly punc- 

 tured, the punctures of unequal size, irregular, not very close together. 



One example from Bugaba has the disc of the thorax nearly black, with the sides 



green. 



A single example from the Volcan de Chiriqui, probably referable to this species, 

 has the head and thorax black and the elytra obscure green.
