Long., c5" 18 mm., $ 14 mm. 



cJ . Closely and finely punctured, the concave portion of 

 the clypeus smooth and shining, seventh dorsal segment 

 longitudinally rugose. Antennae about as long as the thorax 

 and median segment combined, the apical joints arcuate 

 beneath, scutellum convex ; abdomen rather slender ; third 

 abscissa of the radius nearly twice as long as the second, 

 third cubital cell receiving the second recurrent nervure at 

 about one-fifth from the base ; inner tooth of the mandibles 

 obliquely ti'uncate. 



$ . Head finely and closely, thorax more sparsely punc- 

 tured, abdomen almost smooth, the second dorsal segment 

 transversely rugose in the middle between two transverse 

 carinse, the apical margin strongly raised ; pronotum pro- 

 duced in the middle of the anterior margin into a rounded 

 lobe, half as broad again on the anterior as on the posterior 

 margin, slightly depressed in the middle. Abdomen beneath 

 closely punctured ; fifth ventral segment coarsely obliquely 

 striated ; sixth dorsal segment very narrow, pointed at the 

 apex, and fitting into an incision in the broadly rounded 

 lower plate of the pygidium. 



Hab. San Bernardino, Paraguay {K. Fiebrig). 



Type in U.S. National Museum. 



I do not think that this is more than a geographical race 

 of Elaphroptera rubescens, Brethes (An. Mus. Nac. Buenos 

 Aires, xx. p. 239, 1910), but in the description of that species 

 there is no mention of the clypeus being emarginate, and 

 the yellow markings on the scutellum and abdomen differ.
