280 LAMELLICOKMA. 



Yar. Aurea, tibiis et tarsis cupreis. Boucard, Proc. Zool. Soc. 1878, p. 294 3 . 



Bab, Costa Eica, Candelaria Mountains 3 . 



Six examples; all of a silvery hue, like a ball of mercury, to which Salle aptly 

 compares it; the sides of the breast beneath and legs being of the usually smooth 

 subopaque pinkish-clayey hue characteristic of the undersides of all the allied species, 

 but with the centre of the sternum (including the hind trochanters) and abdomen 

 greenish-silvery polished and the tarsi rich violet. The variety described by Boucard 

 is not contained in our collections. 



The specimen figured is from the Volcau de Chiriqui. 



9. Plusiotis badeni. 



Plusiotis badeni, Boucard, Proc. Zool. Soc. 1878, p. 294, t. 16. fig. 2 \ 

 Hab. Mexico, Orizaba (Salle). 



A small, rather oblong species, with a roughly granulate-rugose pygidium, a burnished 

 silvery apical callus, and a long, and slender sternal process. The elytra are somewhat 

 regularly punctate-sulcate, with the alternate interstices (four on each elytron) irregu- 

 larly punctured, as in P. auripes. The sides of the thorax are broadly rosy-red. 



10. Plusiotis lacordairei. 



Plusiotis lacordairei, Boucard, Proc. Zool. Soc. 1875, p. 122, t. 23. fig. 4 1 . 

 Hab. Mexico, Juquila * and Las Peras in Oaxaca (Salle). 



Very closely allied to P. badeni, but the silvery apical callus is larger and still more 

 brilliant and the sides of elytra and body have a silvery lustre ; the sternal process is 

 only about one half the length, though very acute ; and the pygidium is much less 

 roughly punctate-rugulose. The thorax is destitute of red lateral vitta. Three 

 examples, including both sexes. 



11. Plusiotis sallsei. 



Plusiotis sallati, Boucard, Proc. Zool. Soc. 1875, p. 123, t. 23. fig. 3 \ 

 Hab. Mexico, Orizaba 1 (SalU), Jalapa (Hoge). 



Nearly allied to the two preceding, but larger and (in the female) broadly ovate, with 

 remarkably long tapering clypeus ; the pygidium thickly punctured, without rugae. The 

 sternal process is nearly as long as in P. badeni and the sides of the thorax are rosy-red 

 as in that species. The apical callus of the elytra is scarcely shining. Three examples, 

 all females. 



12. Plusiotis auripes. 



Chrysina auripes, Gray in Griffith's Anim. Kingd., Ins. i. p. 517 l (1832).
