624 PHYTOPHAGA. 



Of rather elongate and narrow shape ; the head bluish-Mack at the vertex, very finely and rather remotely 

 punctured ; the frontal tubercles strongly raised, broadly trigonate, and nearly contiguous, scarcely divided 

 by the apex of the clypeus ; the labrum, palpi, and mandibles fulvous ; antennae half the length of the 

 body, the six or seven lower joints fulvous, the others fuscous and each stained with fulvous at the base, 

 the third joint slightly longer and rather more slender than the second, the apical joints somewhat 

 thickened ; thorax twice as broad as long, the sides slightly rounded at the middle only, the surface 

 minutely punctured, fulvous, with a broad but shallow depression on each side ; scutellum black ; elytra 

 dark metallic blue, very closely and distinctly punctured, the punctuation here and there arranged in 

 closely approached rows of larger and smaller impressions, the shoulders rounded ; the breast and the 

 apex of the last ventral segment black, the rest of the underside and the legs fulvous ; the posterior 

 tibiae with the usual spine ; the first joint of the posterior tarsi longer than the following three joints 

 together. 



Eab. Mexico, Ciudad in Durango (Edge). A single specimen. 



15. Monolepta brunnea. 



Testaceous ; head piceous ; antennae fulvous, the sixth to the eighth joints black ; thorax obsoletely impressed, 



obscure piceous ; elytra chestnut-brown, finely punctured, the base distinctly raised. 

 Length 1| line. 



Hah. Panama, Volcan de Chiriqui (Champion). 



M. brunnea is separated from the other small species of the genus by the elytra being 

 distinctly raised at the base and dark brown in colour, in connection with the colour 

 of the antennae and that of the head and thorax. The second and third joints of the 

 antennas are short and equal ; the thorax is more or less stained with piceous ; and 

 the elytra, which are finely and closely punctured, have a transverse depression below 

 the raised basal portion, the depression being slightly darker than the rest of the 

 surface. 



16. Monolepta championi. 



Keddish-fulvous ; antennae pale fulvous, the sixth, seventh, and the apical two joints black ; thorax minutely 

 punctured; elytra punctured like the thorax, reddish-fulvous, the base more or less piceous; legs 

 testaceous. 



Length 1 \ line. 



Head not visibly punctured, deeply transversely grooved between the eyes, the latter very large; clypeus 

 somewhat strongly raised in the middle ; palpi piceous ; antennae half the length of the body, the third 

 joint scarcely longer than the second ; thorax more than twice as broad as long, minutely granulate and 

 punctured ; elytra convex, punctured like the thorax ; the first joint of the posterior tarsi as long as half 

 the tibiae. 



Eab. Panama, Bugaba, Volcan de Chiriqui (Champion). 



Two specimens. M. championi agrees in general shape and colour with M. brunnea 

 and M. triplagiata; but' differs from the first in the elytra not being raised at the base, 

 and from both in the colour of the antennae and in the unicolorous elytra. 



17. Monolepta hondurensis. 



Testaceous, the antennae and tibiae more or less fuscous ; head and thorax minutely granulate and punctured,
