608 PHYTOPHAGA. 



Of this interesting species there is also but a single specimen contained in the Salle 

 collection. The rugose sculpture of the elytra of 8. rugosa is a rare exception amongst 

 the Galerucinae, and entirely in opposition to the smooth and impunctate surface of the 

 preceding species. 



5. Scelida elegans. (Tab. XXXIV. fig. 15.) 



Scelida elegans, Chap. Gen. Col. xi. p. 184, note 1 \ 

 Hah. Guatemala 1 , near the city (Salvin). 



8. elegans served Chapuis for the establishment of the genus, and may be known 

 from its allies by the flavous colour of the head, thorax, underside, and legs, the bluish 

 elytra, and their exceedingly close and distinct punctuation. The specimen in "my 

 collection measures 5 lines. Mr. Champion does not appear to have met with this or 

 the following species. 



6. Scelida balyi. 



Scelida balyi, Jac. P. Z. S. 1878, p. 993 \ 

 Hob. Guatemala, Aceytuno (Salvin). 



The locality of this species was, through an oversight, not given by me at the time 

 of publication 1 . Only a single specimen was obtained by Mr. Salvin. 8. balyi differs 

 greatly from any of the preceding forms by the black vertex of the head and the 

 similarly coloured spots on the coxae ; and also by the shape of the mesosternum, the 

 sides of which are conically raised and produced into a point. 



7. Scelida bella. (Tab. xxxiii. fig. 9.) 



Metallic green, the head, antennae, thorax, and legs flavous ; elytra metallic cupreous, finely rugosely-punctate. 



Length 4 lines. 



Head impunctate ; antennas more than half the length of the body, flavous, the fourth joint slightly longer 

 than the third ; thorax quadrate, narrowed towards the base, the surface flat, with two obsolete foveas, 

 entirely impunctate ; scutellum broader than long ; elytra closely and finely rugose and punctured, of a 

 metallic reddish-cupreous colour ; underside metallic green, covered with yellow pubescence, the anterior 

 portion of the breast and the legs flavous ; the first joint of the posterior tarsi as long as the following two 

 joints together. 



Hah. Panama, Volcan de Chiriqui 3000 feet (Champion). 



S. bella agrees with 8. viridis in the colour and clothing of the under surface ; but 

 differs in the colour of the elytra, the shape of the thorax, and the less elongate first 

 joint of the posterior tarsi. 



8. Scelida metallica. (Tab. xxxiii. fig. 10.) 



Metallic blue or green, the basal joints of the antennas, the head, thorax, and legs fulvous ; elytra scarcely 



visibly punctured, the basal portion raised. 

 Length 3-4 lines. 

 Head impunctate ; antennae slender, the apical joints fuscous, the five basal joints fulvous, the third joint one 



half smaller than the fourth; thorax subquadrate, one half broader than long, the sides straight,
