106 SEEEICOENIA. 



disco bi-impresso ; elytris maculis inconspicuis (quatuor ante medium et duabus ante apicem) griseis, fascia 

 post medium vage cuprascente, nitida, ornatis. 

 Long. 1| lin. 



Hab. Guatemala, Calderas 7000 feet (Champion). 



The head is convex, shining, with an impressed median line ; the top of the head is 

 rugulose, the upper part of the face with rather large punctures, the lower part with 

 transverse shining ruga?. The thorax is broadest just before the front angles, narrowed 

 to the base, striolate, the striolse not very close together, the intervals slightly convex ; 

 the disc has a shallow impression in front, which is confluent with a larger one at the 

 base ; the posterior angles and the base are impressed ; the sides (which are rectilinear) 

 are narrowly but distinctly reflexed. The elytra are rugose, smoother towards the 

 apex, with a brownish-coppery band behind the middle ; each elytron has two 

 indistinct spots near the suture before the middle, and another at a short distance 

 from the apex. The prosternal chin-piece is large, with a deep central emargination. 

 The prostemum is shining, very finely sculptured, without punctures ; the intercoxal 

 process is finely transversely wrinkled, acuminate posteriorly (fig. 15 a). The episterna 

 are shining, punctured on the outer margin. The lateral carina of the basal segment 

 of the abdomen is rectilinear posteriorly. 



105. Agrilus parvus. (Tab. VI. fig. 16.) 



iEneus, nifcidus ; capite convexo, fortiter punctato ; thorace lato, convexo, ruguloso, basi impresso, lateribus 



rotundatis, tenuiter marginatis ; elytris rugosis, immaculatis. 

 Long. 14 lin. 



Hab. Mexico, Guanajuato (Salle). 



This insect is allied to the preceding, but is easily distinguished by the evenly convex 

 thorax, which has the sides unusually rounded. The head is convex (the eyes not 

 prominent), finely coriaceous, and coarsely punctured, the punctures forming curved 

 lines at the top ; there is a shallow small impression above the clypeus, and a not 

 deeply impressed line on the vertex. The thorax is broad and convex, somewhat 

 coarsely and closely rugulose (with a very indistinct indication of a median channel) : 

 rather more narrowed at the base than at the front, the sides arcuately rounded, with a 

 small impression at the base near the posterior angle. The elytra are slightly narrowed 

 below the base, a little broader behind the middle than at the shoulders ; impressed 

 or flattened on the disc. The prosternal chin-piece is gently emarginate. The pro- 

 sternum is shining, with numerous punctures scattered over the surface ; the intercoxal 

 process is acuminate posteriorly. The episterna are finely coriaceous, with a few 

 cuneiform punctures. The abdomen has the lateral carina of the basal segment 

 rectilinear posteriorly.
