114. Agrilus signatus. (Tab. VI. fig. 21.) 



Obscure cyaneo-griseus, pubescens ; tborace leviter convexo, confertim punctato; elytris nigro-velutinis,

This species is very like A. blandulus, but may easily be distinguished by the 

 episterna being very distinctly punctured on the inner half, whereas in A. blandulus 

 they are nearly smooth. The markings on the elytra are also slightly different : there 

 is an oblique spot near the base, an elongate spot at the side about the middle, 

 margined with grey pubescence, and a slightly oblique fascia at a short distance from 

 the apex ; in A. blandulus this fascia is broader and less defined, extending almost to 

 the apex. The femora are blue. 



115. Agrilus albofasciatus. (Tab. VI. figg. 22, 22 a.) 



iEneus, sat nitidus ; capite obscure cupreo, crebre punctulato, medio foveato ; tborace bene convexo, obscure 

 cupreo, transversim sat fortiter ruguloso, medio subcanaliculato ; elytris purpureis, sat crebre asperatis, 

 medio angustioribus, ad apicem obtuse rotundatis, serrulatis, plaga subapicali cyanea, fascia obliqua ad 

 medium, altera ante apicem albis.

Hab. Mexico, Guanajuato (Salle), 



The head is convex, with an ovate impression in front. The thorax is very convex, 

 with no distinct lateral impression, narrowed slightly at the base ; the posterior angles 

 are impressed, slightly diverging ; the median impression is narrow, moderately deep in 

 front, scarcely noticeable posteriorly. The elytra have the subcosta very slightly 

 indicated, and they are rather broad before the apex ; the sutural area near the apex is 

 steel-blue ; there is a small indistinct white spot at one quarter from the base, an 

 oblique spot at the middle, and a much more distinct oblique fascia near the apex ; 

 there is also some white pubescence on the outer half of the apex. The prosternal 

 chin-piece is gently emarginate. The prosternum is rugose ; the intercoxal process is 

 slightly convex, narrowed to the apex. The episterna are sparsely punctured, with a 

 little pubescence at the base and outer margin. The abdomen is rather closely 

 punctured ; the lateral carina of the basal segment is rather strongly angular at the 

 middle, with some silvery-white pubescence above (fig. 22 a) ; the second segment has 

 a white spot at the side. 



116. Agrilus xanthonotus. 



iEneus, nitidus, supra cyaneus ; tborace sat lato, basi angustata, crebre punctato, lateribus impressis, 

 ochraceo-maculatis ; elytris crebre punctatis, maculis sex ocbraceis ornatis, apice quadrispinoso ; corpore 

 subtus ochraceo-maculato.
