374 LAMELLICORNIA. 



Yar. E. sonorce. Angustior, scutello utrinque multipunctato. 



Hab. Sonoea {coll. Bates). 



Allied to E. subtomentosa. The clypeus is short and broad, but not quite so broad 

 or rectangular as in that species. The elytral costse (especially the outer ones) are not 

 nearly so elevated, and the ochreous spots are not arranged in three longitudinal rows, 

 but are in extremely irregular and variable transverse macular streaks ; the apex is 

 broadly ochreous, with a denuded spot in the centre, and there are some transverse 

 streaks on the lateral margins almost as in E. lineoligera. In fact E. histrioniea seems 

 to connect the last-named with E. subtomentosa. The antennal club in the male is as 

 long as joints 1-7, but still not notably elongated, as the whole antenna is short.

 The Mexican examples closely agree with others from Texas. 



CHLOEIXANTHE. 



Corpus elongato-oblongum, supra deplanatum, glabrum. Caput latum; oculi valde convexi; clypeus late 

 quadratus, antice late et recte truncatus marginibus reflexis. Antennae breves, clava <$ $ mediocri. 

 Thorax medio basi valde emarginatus, basi utrinque valde flexuoso juxta scutellum angulatim producto, 

 margine laterali late incrassato. Scutellum elongatum, lateribus longe sinuatis, apice subrotundato. 

 Elytra aequalia, nullo modo costata. Pedes robusti, tibiae 4 posticae extus medio acute unidentatae, apice 

 dentibus 3 elongatis. Mesosternum valde et late productum, late lanciforme, planatum. Tibiae anticae 

 breviter tridentatae, dentibus duobus inferioribus contiguis et conjunctim productis, 3° superiore longe 

 remoto in 3 parvo obtuso, in $ valido et acuto. Tarsi robusti, incrassati, articulis arete colligatis. 



A genus formed for the reception of Euphoria flavoviridis, which, as will be seen 



from the above description, differs in very many structural points from all species of 



Euphoria.

Judging from Dr. Horn's figure and description of the rare North-American
