AGEILUS. 93 



the antennae are very long and slender, even more so than in A. femoralis. The 

 thorax has the posterior ridge very fine but distinct, directed forwards. The elytra 

 have the subcosta fairly well marked and continued nearly to the apex ; the sutural 

 stripe (completely interrupted behind the middle) is of nearly equal width throughout; 

 the apex of each elytron is rounded and finely serrate. The prosternal chin-piece is 

 gently emarginate. The prosternum is densely and finely punctured and pubescent, but 

 the pubescence being rather dark and very fine it is not very conspicuous ; the intercoxal 

 process is flat, with a very faintly raised median line. The abdomen is finely and not 

 very closely punctured. 



71. Agrilus sobrinus. 



Elongatus, angustus ; supra olivaceo-viridis, parum nitidus, subtus aeneus, nitidus ; capite antice sat planato, 

 viridi-aurato, crebre sat fortiter rugoso ; antennis longis ; thorace bic et illic purpureo-tincto, lateribus 

 aureo-marginatis, disco medio linea impresso ; elytris creberrime subasperato-punctatis, vitta suturali 

 parum conspicua pallide flava : femoribus posticis paullo inerassatis, tibiis sat gracilibus, tarsis longis- 

 simis.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith, April 1888). 



The head is longitudinally striolate at the vertex ; when viewed from above it is 

 convex in front, with a slight median impressed line ; the antennae are green at the 

 base, nearly black at the apex, not quite so long as in A. femoralis. The thorax is 

 transversely finely rugulose ; the sides are golden, with a line of coppery above the 

 golden ; the median line is narrow, almost interrupted in the middle ; the posterior 

 ridge is well marked, shining, straight, and directed obliquely inwards. The elytra are 

 scarcely widened behind the middle ; the subcosta is fairly well marked, but does not 

 reach the apex ; the apex of each elytron is obliquely truncate inside and outside, 

 finely serrate. The prosternal chin-piece is gently emarginate in the middle. The 

 prosternum is closely and finely punctured, with scarcely any pubescence ; the inter- 

 coxal process has its margins raised. The metathoracic episterna are finely punctured, 

 slightly pubescent. The abdomen is finely and not very closely punctured ; the basal 

 segment is densely punctured at the sides. 



72. Agrilus cephalotes. (Tab. V. figg. 23, 23 a, b.) 



Elongatus, aeneus, nitidus ; capite antice virescente, creberrime sat fortiter punctato ; thorace convexo, postice 

 paullo angustato, crebre fortiter punctato, transversim subruguloso, disco antice levissime transversim 

 impresso, medio subcanaliculato ; elytris crebre asperatis, postice nigrescentibus, attenuatis, vitta suturali 

 griseo-pubescente, apice denticulato.

Hab. Mexico, Acapulco in Guerrero (Edge). 



This species has the head rather wider than is usual ; the face is rather flat, the 

 lower part covered with very short silvery-grey pubescence. The thorax is coarsely
