Edb. Mexico, Guanajuato (Salle), Cuernavaca in Morelos (Edge). 



I am unable to follow Crotch in connecting this species with E. undulata (Say). It 

 is a smaller, more oval insect, with the border of the elytra neatly yellow from the 

 humeral angle to the apex ; the pale margin is sinuate on its inner side, almost termi- 

 nating at the sutural angle, where it is widened just before the angle, thus representing 

 the apical spot ; and there is one discoidal spot. 



E. elegans is evidently a different species to the one I have recorded here as E. undu- 

 lata, and it agrees well with Mulsant's description 1 . The single example in the Salle 

 collection is a male, with the head yellow ; it was named E. elegans in his collection. 

 E. elegans has not therefore, so far as I am aware, been found in the United States. 



I observe that the lateral margin of the thorax in the single male specimen of 

 E. elegans before me is much narrower than in E. undulata, and that the front margin 

 is not yellow.

This insect is very closely allied to the species here recorded as E. elegans, principally 

 differing from it, in the males, in the absence of a discoidal spot, and in the yellow 

 border of the elytra being distinctly terminated before the sutural angle. The thorax 

 in the male of E. fimbriolata is also very narrowly yellow in front, this not being the 

 case in the single male of E. elegans that I have been able to examine. 



24. Hyperaspis calderana. (Tab. XL fig. 9.) 



Ovato-subquadrata, aurantiaca ; corpore subtus elytrorumque disco nigris, prothoracis disco interdum infumato, 



abdominis apice pedibusque rufis. Long. 3 millim. 

 Mas ? prothorace dilutiore, scutello flavo. 



Eab. Panama, Caldera in Chiriqui (Champion). 



The head is yellow. The thorax is of the same colour (a rich orange-yellow), with 

 the exception that in some specimens the base in the middle and the outline of a 

 roughly-shaped IVI-like mark are indicated, and in these the scutellum is also dark. 

 The disc of the elytra is black, with a ramus extending to the callus, and a second
