Metapocyrtus violaceus sp. nov. Plate I, figs. 9 and 9a, $ . 



Black, with a narrow anterior marginal line on the prothorax 

 and a broad basal and postmedial fascia on the elytra, consisting 

 of violet scales. The fascia in the female iridescent violet with 

 a metallic luster. Rostrum irregularly punctured, abruptly set 

 off at the base by a well-pronounced cross groove. A medial 

 groove in the basal half which extends to the front. The latter 

 with a few scattered scales. Prothorax slightly longer than 

 broad, greatest width before the middle, strongly coriaceous in 

 the female, less pronounced in the male. An anterior and pos- 

 terior submarginal groove. Elytra of female coarsely, irreg- 

 ularly punctured near the suture, confluently toward the lateral 

 margin. Besides the above indicated fascia the female has, at 

 the middle of the lateral margin, an irregular scale spot. The 

 elytra of the female posteriorly, laterally compressed, the poste- 

 rior slope at the suture produced, the latter forming a distinct 

 ridge. Elytra of the male coarsely punctured in fairly regular 

 rows, posterior decline evenly rounded. Apically the margins 

 in both sexes finely setose. Legs castaneous, sparsely punc- 

 tured and finely setose. 



Male, length, 12 millimeters ; width, 4.5. Female, length, 13.5 

 millimeters; width, 5.3.

Metapocyrtus bucasanus sp. nov. Plate I, fig. 10, $ . 



Black, with bluish white scattered scales. Head, prothorax, 

 and elytra similar in form and sculpture to M. violaceus 

 sp. nov. in both sexes, but in form stouter in build, particularly 

 the female, the elytra of which are not compressed posteriorly 

 laterally. Prothorax with an anterior marginal line, the lateral 

 margins of the former with numerous scattered scales. Elytra 

 also with scattered scales, which are condensed in certain places, 

 apparently forming indistinct spots or patches, namely, in both 

 sexes basally and at apical third ; in the female two other small 

 indistinct spots located at the middle, one subsuturally, the other 

 at the lateral margin. Apically, the lateral margins as well as 

 the suture finely setose. Legs castaneous, sparsely punctured, 

 and finely setose. 



Male, length, 12 millimeters; width, 4. Female, length 13.5 

 millimeters; width, 5.8.
