SCOLOCHETJS. 63 



Founded upon a specimen in Clark's collection, and allied to S. curtus, from 

 Cayenne. 



13. Scolochrus Mens. 



Scolochrus fcetens, Suffr. Monogr. xvi. p. 181 *. 



Hab. Panama (Boucard).— Colombia 1 ; Bolivia 1 . 



A specimen from Panama before me belongs to this species of Suffrian, differing in 

 no respect from the Colombian form. The species may be known by its yellowish 

 posterior half, the lateral margin of the thorax and the abdomen being of the same 

 colour. 



14. Scolochrus sulcipennis.

Hab. Panama {Boucard). — Colombia, Bogota \ Ocana 2 . 



A single specimen of this species from M. Boucard's collection does not differ from 

 the Colombian form, a slight variety of which was described by me erroneously as new 

 under the above synonym. The opaque colour of the upper surface, caused partly by 

 the dense punctuation, will distinguish this species from others. 



15. Scolochrus boucardi. (Tab. IV. fig. 8.) 



Below black and yellow, above bright red; thorax with a semicrescent band at each side black; elytra 

 closely pnnctate-striate, the sutnral and lateral margins and two longitudinal bands connected transversely 

 at two places black. 



Length 2\ lines. 



Head closely punctate, red ; vertex, a central spot, and lower part of face black ; thorax with a deep oblique 

 and distinctly punctured groove at each side, rest of the surface very minutely punctate ; disk at each side 

 with a very broad curved band (not extending to the anterior margin, but touching the base) and a small 

 central streak black ; scutellum black ; elytra very regularly and closely punctate-striate, the striae on the 

 disk wider apart than near the sides, the interstices slightly transversely rugose when viewed in certain 

 lights ; a very broad black longitudinal band extends from the base to a little distance from the apex of 

 each elytron, the outer margin of which is concave in the middle, and is connected with the opposite band 

 at and below the middle of the elytra by short transverse branches ; below and the anterior legs black, 

 closely pubescent ; sides of the abdomen and the other legs yellowish, the latter with a black spot at the 

 middle of the femora. 



Hab. Panama (Boucard). 



I am in possession of a single specimen from M. Boucard's collection ; and although 

 it is very probable that the peculiar black markings of the elytra may be subject to 

 variation as in so many other species, yet I know of none with which the present one 

 can be confounded, on account of the close elytral punctuation. T. spadiceus resembles 

 it in the markings of the thorax, which, however, like those of the elytra, are brown 

 instead of black ; moreover the sculpture in the latter species is totally different, as 

 well as the shape of the other markings.
