and greatly produced behind the eyes ; antennae reaching beyond 

 the humeral part of the elytra and somewhat massive, the second 

 joint is only slightly shorter than the third, the fourth quadrate, the 

 fifth to ninth almost quadrate, transverse, the tenth is more trans- 

 verse than the preceding ones, all of them are well separated from 

 each other, and the last one is not equal in length to the two 

 penultimate taken together ; the prothorax is longer than broad, 

 slightly sinuate laterally in the posterior part, the base is arcuate 

 and narrower than the apex, the posterior angles are not as rounded 

 as the anterior, the posterior lateral margin is not impressed, there 

 is a basal transverse impression, and the surface is very deeply and 

 closely punctate, the punctures being divided by a space equal to 

 their diameter ; elytra more closely punctured than the prothorax, 

 and more densely pubescent ; upper part of abdominal segments 

 glabrous, except for a marginal series of remote setigerous punctures, 

 and shiny, except the last one which is scabrose punctate in the 

 male and somewhat pubescent ; third segment of male simple.

MYRMEDONIA GRACILICORNIS, n. sp. 



Head and prothorax testaceous-red, elytra testaceous-red or 

 partly infuscate, abdomen ferruginous with the two abdominal 

 segments black, antennae light ferruginous with the three basal joints 

 and the legs flavescent ; frontal part of male slightly depressed in 

 the anterior part of the vertex, the impression edged by a slight 

 transverse keel between the point of insertion of the antennae,

 part, but not in the anterior, and somewhat densely pubescent ; 

 antennae long, reaching nearly the apex of the elytra, second joint 

 one-third shorter than the third, fourth to fifth elongate, slender, 

 sixth to eighth conical, ninth sub-quadrate, tenth transverse, broader 

 than ninth, eleventh sub-pyriform, sharply acuminate, slightly 

 longer than the two preceding ones taken together, the five ultimate 

 joints are not set close to each other, and they are all setulose at 

 apex, the setic being long ; prothorax as long as broad, narrower at 

 the base than at the apex, plainly sinuate laterally in the posterior 

 part the angles of which are as broadly rounded as the anterior, the 

 outer sides are not depressed, but there is a transverse impression 

 above the base, and the surface is deeply but not closely punctate, 

 and pubescent ; elytra broader than the prothorax at the base,
