ETJPHOEIA. 365 



brassy-green, coppery, and tawny-red with coppery-red gloss; also in the form of the 

 clypeus, which assumes such a diversity of outline in individuals otherwise so nearly 

 alike that no other proof is necessary of the unreliability of this part for classificatory 

 purposes in the group of Cetoniidae to which this genus belongs — it is most frequently 

 rather elongate, curvilinearly or rectilinearly narrowed, with reflexed sub-bidentate 

 apex; from this it rapidly varies to trapezoidal and to semiovate with or without 

 strongly raised margins and entire apical border, and to short and transverse with high 

 and entire margins. The variety rufina will be seen, from the localities enumerated 

 above, to have a more northerly or elevated range than the type-form, and it is often 

 much more densely pubescent above, but insensible gradations connect the two forms. 



6. Euphoria limatula. 



Euphoria limatula, O. Janson, Cist. Entom. ii. p. 585 *. 



Edb. Mexico, S.W. Yucatan (Br. Horn); Guatemala 1 (Salle), Aceytuno 5100 feet 

 (Salvin), San Geronimo (Champion); Nicaragua, Chontales (Belt) ; Costa Rica (Van 

 Patten). 



A good series of examples. The prevailing colour is, as the author describes it, dark 

 greenish-blue, but it varies, and a rufous variety (like that of E. leucographa) is not 

 uncommon. The species scarcely differs from E. leucographa, except in the sparser 

 punctuation and impunctate dorsal vitta of the thorax, and in the generally shorter 

 clypeus, which latter varies in the sinuation of the apex, but less so than in E. leueo- 

 grapha. The transverse chalky spots on the sides of the ventral segments exist only in 

 a few examples of the male, and the metasternum has sometimes on each side, visible 

 under the long grey pubescence, a few large scale-like whitish spots. 



7. Euphoria yucateca. 



E. limatulce proxime affinis, sed differt brevius oblongo-ovata, thorace et elytris adhuc sparsius punctatis, meta- 

 sterno ventreque in S lateribus late cretaceo-albis illo vix hirsute Cyanescenti-viridi-senea, raro obscure 

 cuprascenti-senea, elytris sicut in afflnibus cretaceo-maculatis et thoracis lateribus latius albo - vittatis ; 

 clypeo sEepe Eeneo, obtuse quadrato vel semiovato marginibus parum reflexis, apice interdum sinuato, ssepe 

 maculis duabus cretaceis; thorace sparsissime punctato, medio lsevi; elytris sparse arcuatim (lateribus 

 strigulatim) punctatis ; pygidio maculis duabus grossis cretaceis ; pectore multo brevius cinereo-hirsutis, 

 metasterno lateribus in S fere toto, in $ maculatim cretaceo, ventre utrinque in <S late, in $ maculis 

 tantum parvis lateralibus, cretaceis.

Edb. Mexico, Temax in North Yucatan (Gaumer). 



A large number of examples. According to the description and figure of Gory and 

 Percheron this species must resemble E. bivittata of Guiana; but in no example is 

 there a trace of the two cretaceous vittse of the disc of the thorax which distinguish 

 E. bivittata. 



Obs. — There is an example of E. lurida (Fabr.) in the Salle collection labelled
