is a little narrower in front than behind, without any discoidal fovea ; the posterior 

 ridge is very short, and often very indistinct. The elytra are relatively a little shorter, 

 less attenuated at the apex, and wider behind the middle than at the shoulders ; the 

 granulation is a little less even and the granules are slightly separated from each 

 other. The episterna are rather closely rugose, not pubescent. The abdomen has 

 the lateral carina of the basal segment rectilinear posteriorly. The antennae are 

 moderately long and broad. 



ill. Agrilus planatus. (Tab. VI. fig. 19.) 



Niger ; capite thoraceque seneis, hoc basi rufo-cuprea ; elytris confertim granulatis. 

 Long. 3-3| lin. 



Hab. Guatemala, near the city, Duenas {Champion). 



This species is very close to A. planipennis, but is relatively narrower, the elytra 

 longer and less dilated behind the middle. The head is more shining, and the impres- 

 sion is narrower and not so deep on the vertex, so that it is not so noticeable when 

 viewed from above. The antennse are perhaps a little broader (fig. 19). 



112. Agrilus gracilitarsis. (Tab. VI. fig. 20.) 



Obscure seneus; thorace rufo-cupreo, margine antico medio seruginoso, basi foveola notata; elytris griseo- 



nigris, brevissime pubescentibus, confertim subtiliter granulatis. 

 Long. 3| lin. 



Hab. Guatemala, Capetillo (Champion). 



This species is closely allied to the preceding, but is longer and narrower, the elytra 

 being about four times the length of the thorax, whereas in A. spissus they are only 

 three times as long. The head is blackish; the impressions are similar but less 

 distinct ; when viewed from above it appears to have scarcely any frontal impression. 

 The thorax is rather broad in front, gradually narrowed posteriorly, finely rugulose ; 

 dull reddish-coppery with a bluish-green mark in front ; there is a distinct elongate 

 shining fovea in the middle near the base. The elytra are more gradually attenuated 

 posteriorly. The posterior tarsi are very long and slender. The prosternal chin-piece 

 is distinctly emarginate. The prosternum is rugose ; the intercoxal process is obliquely 

 acuminate posteriorly. The episterna are rather strongly and moderately closely 

 punctured, sparsely pubescent. The abdomen has the lateral carina of the basal 

 segment a little more bent at the middle.
