genera and species of Buprestida. 



183 



The head is closely punctured, with a deep shining excavation 

 between the eyes. The elytra at the base are as broad as the 

 thorax, narrowed slightly just below the 

 shoulders, and then subparallel to the ex- \ 

 panded apex. The shoulders are elevated 

 into a short curved costa, deeply impressed 

 within ; the usual costa reaches from the 

 shoulder to the apical declivity. The pro- 

 sternal process is closely and very coarsely 

 punctured. The middle of the metasternum 

 is brassy. The abdomen is not very closely 

 punctured. 



Hab. Brazil, Santa Martha. 



Since the above was written I have 

 seen M. J. Thomson's description of 

 Agrilus omocyrius (Typi, Append., 

 p. 58), and think it possible that they 

 may refer to the same species. In that case, however, 

 M. Thomson's description appears incorrect. The 

 shoulders of the elytra do not project, but are elevated. 

 The elytra have a black fascia before the middle and a 

 second behind, not two behind the middle. The pro- 

 sternum is not striolate, but deeply punctured. 



Omochyseus terminalis, n. s. 



Praecedenti similimus ; thoracis lateribus postice minus angu- 

 latis, plagis discoidalibus elevatis punctatis ; elytrorum costa ante 

 apicem evanescenti, apice haud dilatato. Long. 12 mm. 



This species very closely resembles the preceding. The thorax 

 is, however, less angular at the sides, but especially the raised spot 

 on each side of the front of the disk, instead of being smooth, is 

 coarsely punctured. The costa on the elytra does not quite reach 

 the apical declivity. The apical declivity is slightly cyaneous, 

 transverse, somewhat trapezoidal in outline, not dilated and 

 rounded on the outer side. 



Hab. Mexico, Oaxaca. 



Paradomorphus, n. g. 



I propose this name for Agrilus frontalis, L. & G., 

 and some allied species, which differ from Agrilus in 

 having the basal joint of the posterior tarsi comparatively 

 short.
