AGEILUS. 121 



Bab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn), Guanajuato (Salle). 



The head is closely rugose, impressed in front. The thorax is strongly and closely 

 punctured, but the punctures are slightly separated on the disc ; the median channel 

 is deep, rather more narrowed in front than at the base ; there is a slight swelling at 

 the posterior angles ; the sides are rather straight. The elytra have the subcosta 

 slightly marked, and between it and the suture there is a less definite, fine, shining, 

 raised line ; the punctures are somewhat cuneiform, generally a little separated from 

 each other, those in the sutural region being finer and closer than those at the sides. 

 The prosternal chin-piece is gently and widely emarginate. The prosternum is rather 

 closely and strongly punctured ; the intercoxal process obliquely narrowed at the apex, 

 where it is deflexed. The episterna are closely punctured. The abdomen is very finely 

 punctured and densely so at the sides ; the basal segment has an impressed line at the 

 sides indicating the division between the first and second segments ; the lateral carina 

 has a distinct curve before the apex of each of the basal segments. The whole of the 

 upperside of the insect is slightly pubescent. The whole of the underside is more or 

 less clothed with yellowish-grey pubescence : it is sparse in the central parts, but close 

 and longer at the sides. 



139. Agrilus phsenicopterus. 



Elongatus, crassus, postice parum angustatus, nitidus, rufo-cupreus, vel viridis, vel cyaneus ; capite rugoso, 

 fronte impressa; thorace subquadrato, fortiter punctato, medio profunde canaliculato ; elytris crebre 

 subrugoso-punctatis, costatis. 



Long. 4J lin. 



Hah. Mexico, Cordova, Tuxtla, Juquila (Salle), Mexico city (Hoge). 



The head is longitudinally impressed in front, and has a transverse impression on the 

 forehead. The thorax is not more narrowed at the base than in front ; the punctures 

 are strong, close together at the sides, but on the disc they are distinctly separated 

 from each other ; the median channel is deep, with some golden pubescence at the 

 bottom ; there is an oblique lateral impression and a swelling at the posterior angles 

 representing the posterior ridge. The elytra are somewhat parallel, narrowed at the 

 apex ; each elytron has two shining costse, which do not extend to the apex. The 

 prosternal chin-piece is rather straight in front, with a slight sinuosity in the middle. 

 The prosternum is strongly punctured, shining, the punctures not crowded ; the inter- 

 coxal process is slightly arched posteriorly, rounded at the apex. The sides of the 

 sternum are sparsely pubescent. The episterna are almost without pubescence, shining, 

 convex, finely and closely punctured. The abdomen is finely and not very closely 

 punctured ; the basal segment has an impressed transverse line at the sides indicating 

 the division between the true first and second segments ; the upper margin has four 

 shallow impressions, which are filled with whitish pubescence ; the lateral carina of 

 the basal segment is interrupted by the first and second impressions.
