284 • LAMELLICOENIA. 



An oblong species of dark-green colour with strong metallic gloss, especially on the 

 margins, scutellum, abdomen, and pygidium ; the elytra punctulate-sulcate ; and the 

 head (especially the clypeus) smaller than in the allied species. The sternal process 

 is very short, tuberculiform, and hidden in the long fulvous villosity of the pectus. 



The Orizaba example in the Salle collection is much larger than those from northern 

 localities (30 millim., <s ). 



A specimen from Ciudad is figured.

 [Buchan- Hepburn). 



We have only one much damaged example of this distinct species, which is regularly 

 and rather distantly punctured (without impressed striee) over the elytral surface. The 

 colour is a beautiful light green, metallic on the under surface. The sternal process 

 is very short, tuberculiform. 



22. Plusiotis chalcothea. (Tab. xvi. fig. 8.) 



Elongato-oblonga, convexa, saturatius fusco-aenea, nitidissima, viridi-ameo-relucens ; capite parvo, dense punc- 

 tato, vertice lseviore ; clypeo antice triangulari, apiee anguste producto et reflexo, d breviore, ? longiore ; 

 thorace convexo a basi ad apicem curvatim angustato, angnlis anticis obtusis, posticis subrectis, margine 

 basali medio subinterrupto, snpra disco minutissime sparsim punctulato vel lsevi, lateribus et sulculo 

 marginali grossius et crebrius punctatis ; elytris punctulato-striatis, stria suturali versus apicem profunde 

 impressa, margine laterali ( c? $ ) teimi. Pygidium ( c? $ ) mediocriter convexum, sparsim longe pilosum, 

 minute punctulatum vel strigulatum vel fere lseve, splendide viridi-seneum. Subtus cum pedibus viridi- 

 asnea, nitida, bis plus minusve piceo-rufo-translucentibus, pectore et abdomine lateribus longe fulvo-villoso. 

 Sterni processus minutus, tuber culiformis. 



Long. 25-31 millim. tf 2 • 



Hab. Costa Rica ( Van Patten). 



This species approaches the Colombian P. anomala (Burm.) in some of its characters, 

 but it is a more typical Plusiotis ; the postcoxal process of the presternum is well 

 developed, but bends at an obtuse angle, and the apical part between the coxae is 

 unusually broad. 



Eight examples.
