LAMELLICOENIA. 



12. Cotinis olivia. (Tab. xxi. fig. 10.) 



C. polite afflnis, sed differt hirsutie pedum et pectoris vulpino-rufa nee nigra, coloreque olivaceo-viridi vel 

 seneo-olivaceo ; glabra, metallica. A G. subviolacea differt corpore angustiore, comu clypeali nuUo sed 

 clypei margine antice acute rotundato reflexo, medio altiore, carina frontali baud libera, apice declivi et 

 fere ad clypei apicem extensa. Thorax postice minus ampliatus; lateribus ante angulum distinctum 

 posticum smuatis, discrete punetatis, punctis majoribus et minoribus intermixtis. Elytris ingequalibus, 

 subtihssime distanter sublineatim punctulatis. Pygidium subtilissime strigosum, apice fere leeve. Pro- 

 cessus sternalis parte mesosternali lata et brevissima, apice obtuse truncata. 



Long. 23-30 millim. $ . 



Eab. Costa Rica (Van Patten), Rio Sucio (Rogers). 

 Five examples, apparently all females. 



13. Cotinis antonii. 



Cotinis Antonii, Duges, La Naturaleza, iv. p. 170 (1879) 1 . 

 Cotinis senex, O. Janson, Cist. Entom. ii. p. 575 (1880) 2 . 

 Latemnis Antonii, Thomson, Le Naturaliste, i. p. 268. 



Hah. Mexico 2 , Guanajuato 1 (Luges, in coll. Salle), Tupataro in Guanajuato (Edge). 



Wholly violet-black, the pubescence beneath black. The frontal carina is short and 

 elevated, and terminates abruptly ; the reflexed apex of the clypeus is often very 

 distinctly higher in the middle and can never be called truncate. The sternal process 

 is flat, but somewhat acutely rounded at the apex as in C. producta. 



14. Cotinis alboscripta. 



Gymnetis alboscripta, O. Janson, Cist. Entom. ii. p. 301 \ 



Hab. Mexico, Almolonga (Edge), Amula in Guerrero (E. E. Smith), Oaxaca \ 



In this, the most aberrant species of the genus, the frontal carina though distinct blends 

 gradually in front with a slight convexity in the middle of the clypeus, which latter 

 has no trace of dentiform projection in the middle of the front edge; the sides of the 

 forehead and truncated clypeus are equally and rather strongly elevated ; the sternal 

 process has the flat obtusely rounded form prevalent in Cotinis. 



II. Coxae posticw angulis posticis obtusis (gen. Balsameda, Thorns.). 



15. Cotinis cincta. 



Gymnetis cincta, Gory & Perch. Monogr. Cetoin. p. 339, t. 67. fig. 6 1 . 

 Cotinis cincta, Burm. Handb. der Ent. iii. p. 262 2 . 



Eab. Mexico 2 . — Interior of Brazil 1 (locality erroneous, according to Burmeister). 



Our collections contain nothing resembling this species. 



Obs. Gory and Percheron give Mexico as the locality of another species, C. terminata, 

 which Burmeister says is also erroneous, the species being from Brazil.
