350 LAMELLICOENIA. 



The margins of the thorax are distinctly less broadly incrassated than in C. mutabilis 

 and C. punctato-striata ; in this respect the species approaches the North-American 

 C. nitida. The colour varies : (1) dullish green, very dark and tinged with brassy 

 beneath ; (2) the same, with the margins of the thorax and the whole of the elytra, 

 except a broad triangular juxtascutellar patch, dull fulvous ; (3) wholly fulvous above, 

 except the disc of the thorax, which remains green ; (4) thorax and elytra entirely 

 fulvous. The length ranges from 21 to 23 millim. 



5. Cotinis pueblensis. (Tab. XXII. figg. ll, ll a.) 



C. pauperulce quam proximo affinis, sed differt duplo majore et robustiore ; nigro-viridis, opaca, elytrorum 

 lateribus obscure rufo translucentibus, subtus nigro-senea, nitida ; carina frontali antice leviter declivi, 

 cornu clypeali late triangulari ; thoracis margine latins incrassato, antice obsoleto et cum lateribus sparsim 

 grosse punctato ; elytris passim grosse striato-punctatis ; processu sternali antice (parte mesosternali) trans- 

 verso et subacute rotundato ; metasterno coxisque posticis angulis postero-externis sicut in G. mutahili et 

 afflnibus acute productis ; subtus pubescentia vulpino-rufa. 



Long. 28 millim. tf (?). 



Hab. Mexico, Matamoros Izucar in Puebla [Edge). 



Possibly a local or geographical form of C. pauperula. One example only. 



6. Cotinis producta. 



Elongato-oblonga, viridis, opaca, subtus metallica, elytris fulvis, sutura et plaga juxtascutellari viridibus ; cornu 

 clypeali brevi, latissimo, apice paullo dilatato, postice concavo-arcuato apice truncato ; cornu frontali fere 

 usque ad cornu clypeale extenso, apice fere verticali vix libero ; tborace postice minus dilatato, passim 

 sat grosse punctato, lateribus late glabris nitidis, margine sat incrassato ante apicem obsoleto; elytris 

 punctulato-striatis ; pygidio sicut in affinibus dense striguloso ; processu sternali brevi, parte mesosternali 

 parva triangulari ; tarsi breves et robusti, posticis articulis l°-4 m longitudine sequalibus.

xlbout a score examples answering to the above-cited descriptions and figure, except 

 with regard to the pygidium, the great peculiarity of which, namely its opaque surface, 

 is not mentioned. The insect is of the broad robust form of the typical C. mutabilis 

 (28-35 millim.), though rare examples occur of rather smaller and narrower outline ; 

 the colour above is dark olivaceous-green, beneath red-coppery, inclined to seneous in 

 Taboga Island examples. It differs constantly from G. mutabilis, apart from the opaque
