whole length of the elytra, although rather less distinct posteriorly in the female; each 

 elytron has a spot of dirty yellow pubescence in the basal impression, a short streak at 

 the middle (sometimes broken into two small spots), and a small spot at some distance 

 from the apex. All the underside of the insect is sparingly clothed with short fine 

 pale grey pubescence, which, however, is more dense at the sides of the abdomen, but 

 scarcely forms spots. The presternum is densely and very finely rugose ; finer in the 

 male than in the female. The anterior and intermediate femora are obscure green in 

 the male.

This is a moderately narrow species, gradually attenuated posteriorly. The head is 

 very flat in front and extremely finely granular ; the vertex is unusually smooth, with 

 some extremely fine punctures. The thorax is evenly convex, with an indication of a 

 longitudinal median impression, only visible in some lights ; the posterior ridge is fine 

 but distinct, shining, directed forwards, very slightly curved. The elytra have the 

 subcosta distinct but obtuse, nearly straight, gradually approaching the suture at the 

 apex ; the apex of each elytron is obliquely truncate inside and outside. The prosternal 

 chin-piece is distinctly emarginate. The prosternum is not very closely punctured. 

 The episterna have the outer half clothed with greyish-white pubescence ; the inner 

 half is smooth, with some very fine punctures. The abdomen is finely and not very 

 closely punctured, except at the side of the basal segment, where the punctuation is 

 close ; there is a sparsely pubescent spot near the side of the basal segment. 



The example from Chontales is of a brighter green than those from Cordova. 



59. Agrilus hilaris. 



Supra nigro-seneo-virescens, parum nitidus, subtus aeneus nitidus; capite antice planato, subsurdo, crebre 

 subtiliter punctulato, seneo-viridi vel cupreo ; thorace transversim ruguloso, obsolete punctulato, basi medio 

 leviter impresso ; elytris tenuiter asperatis, maculis sex (vel octo) flavo-griseis ornatis, ad apicem attenuatis, 

 serratis.
