CETONIIN/E 297 



the male, so that the hind tarsi in this species, which seems to be 

 rather isolated, are shorter than usual; the head is much larger than 

 in any of the forms of atrata and the clypeal horn very different. 

 The form identified by Mr. Bates as nigrorubra G.&P., is evidently 

 not the same as capita, differing in coloration, as well as in its 

 notably larger size. The clypeal process in atrata is always small, 

 triangular or parabolic, perhaps quadrate as an extreme, though 

 I have not seen that development; it seems to be more constant 

 than in some other species, but less so than in lebasi, 



*Cotinis lebasi ssp. panamensis nov. Similar to lebasi in general 

 features but shorter, with more rapidly cuneiform hind body; upper 

 surface densely opaque, very obscure olivaceous green, shading broadly 

 postero-externally into red-brown, the pygidium obscure red-brown, 

 similarly opaque and sculptureless, except near the ends and with the 

 lower margin likewise narrowly metallic and shining; under surface 

 polished, very obscure bronze, head barely a third as wide as the pro- 

 thorax, shining, greenish-bronze, strongly and conspicuously punctured, 

 the suture between the front and clypeus more distinct than in any other 

 species and accentuated by an abrupt depression of the clypeus below 

 the level of the front; frontal ridge more punctured than usual and with 

 its tip free for only a very short distance, the apex feebly inflated; clypeal 

 horn small and triangular; prothorax as in lebasi, except that the green 

 gradually becomes obscure brownish along the sides; elytra similar, except 

 in coloration and in the greater attenuation, the apex being barely more 

 than two-thirds as wide as the base; sternal punctures coarse and con- 

 spicuous, the hind tarsal plate very feebly sculptured in fine sparse oblique 

 wavy lines; anterior tibiae stout, tridentate as usual. Length ( 9 ) 28 

 mm.; width 16.4-16.6 mm. Panama (Culebra Cut), Gaillard. 



The two females at hand have been compared with a single 

 female of lebasi, marked "Chiriqui," which seems to agree very 

 well with that originally described from Carthagena, Colombia. 

 There is no trace of the brilliant coppery-red under surface of 

 lebasi, and the cephalic ridge has its apex very much less strongly 

 expanded; the sternal process is similarly very broad. 



Tribe CETONIINI. 



This tribe includes all the American species classified under the 

 title "Cetonides vraies" by Lacordaire and they were all assigned 

 by him to the genus Euryomia, with the statement that Euphoria 

 was simply a name for the species of a special zoological region. 

 The different forms assumed by the clypeus were enumerated as 

 showing the impossibility of giving Euphoria any definite standing,
