XT. New genera and species of Buprestidse. 

 By Charles 0. Waterhouse. 



[Read May 4th, 1887.] 



Whilst I have been engaged in determining the 

 Buprestidce of Central America, I have found it necessary 

 to propose several new genera. Some of them are not 

 founded on Central American species, and I have there- 

 fore thought it best to publish them in the present 

 paper, as they cannot conveniently be inserted in the 

 ' Biologia Centrali Americana.' 



Mixochlorus, n. g. 



Antennal pores in a cavity on the lower internal margin of the 

 joints. Scutellum small, transverse, trapezoidal. Sternal cavity 

 formed by the meso- and meta-sterna. Head gently convex in 

 front. Antennal cavities small, round. Thorax a little broader 

 than long, not much narrowed anteriorly, with three longitudinal 

 impressions above ; the central one extending from the base to the 

 front margin, broader at the base than in front; the lateral 

 impressions do not reach the anterior margin. Posterior angles 

 acute, scarcely diverging. The base gently bisinuate. Elytra at 

 the base as broad as the thorax, scarcely sinuate at the sides, 

 gradually narrowed to the apex ; punctate-striate ; longitudinally 

 impressed at the suture. Tarsi short, the basal joint about as long 

 as the two following joints together. Claws angularly dilated at. 

 the base beneath. 



The species for which 1 propose this genus might at 

 first sight be taken for one of the Agrilidce. _ It is, 

 however, clearly allied to Agaocera (Waterh., Biologia 

 Cent. Amer., Coleopt., iii., pt. i., p. 4), and should be 

 placed near Pelecopselaphus. It differs from Agaocera 

 in its narrower form ; the elytra are not costate, and the 

 claws are dilated at the base.
