ADEPHAGA. 



(Hoge) ; Guatemala, Chiacam, Panzos, Chacoj (Champion) ; Nicaragua, Chontales (Belt, 

 Jansori) ; Panama, Volcan de Chiriqui ( Champion) . 



Differs very slightly from the widely distributed South- American C. picea, having the 

 elytra a little broader posteriorly, and the colour being generally darker. It cannot be 

 more than a northern form of that species. 



9. Coptodera chloris. 



C. tripartite^ affinis, sed magis elongato-oblonga, signaturisque dissimilibus. O. lehioidi proximior, signaturis 



simillimis sed striis minus distincte punctatis ; major et magis oblonga, elytris saturatius nigro- vel 



olivaceo-viridibus ; thorace valde transverso, quam in C. tripartita latiore, angulis posticis obtusis fere 



rotundatis ; elytris baud profunde striatis interstitiis fere planis, nitidis, margine et fasciis duabus flavis ; 



fascia prima extus angustata, lineolis apud interstitia 7 m et 8 m brevissimis, apud interstitia 4 m et 6 m elon- 



gatis prsecipue postice prolongatis ; vertiee et thoracis disco interdum fusco-maculatis. 

 Long. 2|-3| lin. 



Hab. Mexico, Mirador (Hoge, Flohr). 



Belongs to a difficult g 



of species, of which G. tripartita is the type. From 



C. tripartita it is distinguishable at once by the lineole of the first fascia on the fourth 



being much 



ged behind, the same lineole in C. tripartita being much 



abbreviated posteriorly. In this respect it agrees with C. lebioides, a smaller 

 from the Amazons and Ecuador (2-2

which I hesitate to refer 



different facies, due to the more oblong form of its elytra, less conspicuously 



punctured striae, and darker g

10. Coptodera flavodisca. (Tab. VII. fig. 16.) 



Coptodera flavodisca, Chaudoir, Mem. s. 1. Thyreopt. p. 77 \ 



Hab. Guatemala, San Geronimo, El Tumbador, Zapote, Balheu (Champion) ; Nica- 

 ragua, Chontales (Belt, Janson) ; Panama, Volcan de Chiriqui, Bugaba ( Champion). 

 South America, Amazons 1 . 





The extent of the yellow oval spot in the common centre of the elytra varies, 

 diminishing, but not regularly, with the distance from the equator ; thus in Panama 

 the type form occurs in company with a variety in which the yellow spot is reduced to 

 a stripe not extending beyond the fourth striae, whilst at Chontales only the type form 

 seems to occur, and in Guatemala the type form is altogether absent, and the spot is 

 lessened, as in the Panama variety, or disappears altogether. The extreme unicolorous 

 variety has so distinct a facies that it is convenient to give it a separate name and 

 mention. 







Var. 0. immaculipennis. Elytra unicoloria, magis olivaceo-aenea, interdum disco obscure rufescens, margi- 

 nibus pallidis. 



Hab. Mexico, Cerro de Plumas (Edge) ; Guatemala, San Geronimo, San Joaquim, 

 Tamahu, Balheu (Champion).
