COTINIS. 349 



of general form of body; some examples ( <$ ) are small (19 millim.) and narrow, others 

 ( 6 ) remarkably elongate (28 millim.) without corresponding width and with high 

 parallel-sided clypeal horn, whilst others ( $ , 26 millim.) have the broad oblong- ovate 

 outline of C. mutabilis typical form. Male examples also occur with a clypeal horn so 

 excessively reduced that it appears only as a small obtusely triangular elevation. 

 An example from Guanajuato is figured. 



3. Cotinis punctato-striata. (Tab. XXII. figg. 9, 9, a 6 .) 



0. mutabilis varietatibus minoribus similis, sed differt elytris scintillanter punctulato-striatis. Colore variat : — 

 (1) Viridi-concolor (subtus aurato-viridis metallica) ; (2) viridis, elytrorum vitta lateral! usque ad suturse 

 apicem extensa obscure rufa ; (3) viridis, thoracis lateribus vittaque dorsali et elytris toto (sutura et plaga 

 magna triangulari juxtascutellari exceptis) obscure fulvis ; (4) cupreo-aurata, subtus resplendens rufo- 

 relucens ; et (5) purpureo-fusca, subtus castanea haud metallica. Cornu clypeale sat elongatum, plerumque 

 triangulare acutum, interdum truncatum, raro lateribus subparallelis ; cornu frontale interdum angustum, 

 apice haud longe liberum. Pygidium et processus sternalis sicut in 0. mutabili. 



Long. 21-25 millim. S $ . 



Eab. Mexico, Vera Cruz (Salle), Almolonga, Jalapa (Edge) ; Nicaragua, Granada 

 (Salle). 



The shining punctured striae are visible chiefly in the depressed intervals between 

 the suture and the first costa and between the two costee ; they are in each interval 

 two in number, and the space between the first pair is irregularly punctured ; the apex 

 between the callus and the suture is also more or less punctured. The males are 

 slenderly oblong, like the smallest males of C. mutabilis ; the females are more robust 

 and subquadrate. The species was captured in abundance by Herr Hoge at Almolonga ; 

 it is in many points intermediate between C. mutabilis and C. pauperula. 



The single female example from Granada, Nicaragua, differs from all the others in 

 its larger size (28 millim.), and broader, more robust figure. It resembles, in fact, 

 closely, certain Guatemalan examples of C. mutabilis, typical form, which have a broadly 

 triangular clypeal horn, except in the numerous shining green punctures of the 

 elytra. 



4. Cotinis pauperula. (Tab. xxii. fig. 13.) 



Cotinis pauperula, Burm. Handb. der Ent. v. p. 550 \ 



Eab. Mexico 1 , Acapulco (J. J. Walker, Edge), Iguala in Guerrero (Edge), Yolotepec 

 (Salle). 



Smaller in size and more slender in form than any but exceptionally dwarfed examples 

 of C. mutabilis or than C. punctato-striata. It agrees with the latter in the punctate- 

 striate elytra, but the punctures are opaque ; and it also differs in the frontal horn being 

 reduced to a sharp carina, never free, though nearly always vertically truncated at the 

 extremity. The clypeal horn is always very short and triangular, and the sternal 

 process somewhat narrow and rather more acutely rounded at the apex than in C. mutabilis.
