terminal segments ; the apex is broadly truncate ; the sides of the basal segment are 

 steel-blue ; the second segment has a distinct whitish spot at the side ; the lateral carina 

 of the basal segment is very slightly sinuate behind the middle, with a white spot 

 above.

 Hah. Mexico, Alvarado \ 



This species has a fine posterior ridge to the thorax, close to the margin, and scarcely 

 visible from above. It much resembles in general appearance A. confusus, Waterh., 

 near to which it might be placed were it not for the ridge on the thorax. 



77. Agrilus nigripennis. 



^Ineo-niger, parum nitidus ; capite viridi-seneo ; thorace cuprascente, transversim striolato, medio bi-impresso ; 



elytris nigris, tenuiter asperatis, ad apicem bene acuminatis. 

 Long. 2|-2| lin. 



Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; Panama, Bugaba, Volcan de 

 Chiriqui 3000 to 4000 feet, Los Remedios (Champion). 



The head is generally green, but sometimes coppery, rather closely punctured, longi- 

 tudinally impressed in the middle, with a very slight impression above the clypeus. 

 The thorax is marked with rather closely-placed, curved, oblique, punctured striolae ; 

 the disc has a slight longitudinal impression, which in some lights appears to be 

 divided into two. The elytra are slightly asperate, and somewhat finely rugose below 

 the scutellum ; the subcosta is only slightly marked ; each elytron has two very small 

 teeth at the sutural angle, then a slight interval between the series of small teeth on 

 the outer margin. The prosternal process is closely and very finely rugose in the 

 middle. The metasternum is rather strongly and moderately closely punctured ; the 

 episterna are closely and finely punctured. The abdomen is rather strongly and 

 moderately closely punctured. 



Two or three examples out of a long series from Teapa have the elytra bronzy. 



78. Agrilus apicatus. (Tab. VI. figg. 2, 2 a.) 



Elongatus, subparallelus, sat angustus, niger, nitidus; thorace seneo, bene convexo, tenuiter transversim 



ruguloso ; elytris tenuiter asperato-punctatis, singulis ad apicem excisis. 

 Long. 2| lin. 



Hab. Guatemala, Dueiias (Champion). 



The head is convex, finely and closely punctured ; with a lightly impressed line on 

 the vertex ; the lower part of the face is aeneous. The thorax is very convex (with 

 scarcely any trace of impression at the sides or posterior angles), slightly narrowed at 

 the base, with the posterior angles somewhat diverging ; finely punctured and slightly
