CALLEIDA .

colours ; but some of the Actopan examples are intermediate in all respects. Average 

 specimens, constituting the majority, are easily recognizable. Some, with rufescent 

 explanated margins of the thorax, resemble, at first sight, C. metallescens.

Motschulsky's description of C. aurata applies almost equally well to C.jansoni, but 

 with regard to colours fits much better the present species. " Elytris aureo-violaceis vel 



fulgidis " does not apply to the lustreless purple-copper hue, changing into dark purple, 

 which characterizes the elytra of C.jansoni. The sculpture of the elytra, however, 

 suits neither ; and it is possible C. aurata may be a third species different from either. 





22. Calleida tropicalis. (Tab. IX. fig. 5.) 



Elongata, antennis pedibusque gracilibus ; rufo-ferruginea, elytris (nisi versus suturam) viridi-seneis splendidis 



(epipleuris ferrugineis), eapite mox pone oculos angustato, collo distincto ; thorace oblongo sat angustato, 

 apice modice rotundato, angulis posticis subobtusis, margine laterali explanato-reflexo, lateribus trans- 

 versim strigosis ; elytris oblongis, apice sinuato-truneatis, angulo exteriore prominente obtuse dentato, 

 suturali recto, dorso versus basin depresso, callo oblongo marginali-apicali, acute striatis, striis subtiliter 

 punctulatis, interstitiis planis, tertii puncto anteriore paullo ante medium sito.

I have adopted the MS. name given to this species by Baron Chaudoir in the Salle 

 collection. Although thus named, I think it very likely that the species is the original 

 C. dives, described by Chaudoir in 1852 from a specimen in Dupont's collection, which 

 had passed out of the describer's reach when he redescribed the species from a second 

 example evidently not belonging to it. 



The male has two anal punctures on each side, the female three or four. A male 

 from Costa Rica (Cache) taken by Rogers is very puzzling, having only one anal seta 

 on each side (and therefore referable to Section I.), although it presents no other differ- 

 ence of importance from the Mexican examples. Whether it be a mere aberration or 

 a distinct species, cannot be decided until further specimens are forthcoming.

C. tropkali affinis, minus elongata, elytrisque rufo- vel viridi-aureis, versus latera et apicem igneo-cupreis

 plus minusve strigoso ; elytris elongato-oblongis, apice truncatis, angulo exteriore paullulum producto sed
