Ceratinoptera puerilis new species. 



Type: cf ; Misiones, Argentina. July 30, 1909. (P. Jorgensen.) 

 [Acad. Nat. Sci. Phila., type no. 5230.] 



In general form this species is apparently closest to C. otomia 

 (Saussure)-^ from Mexico, from which, however, it differs in the 

 larger size, the more extensive tegmina, which reach to the base of 

 the fifth abdominal segment, the more rounded distal margin of the 

 tegmina, the emarginate supra-anal plate and the different coloration. 



Size medium; form subovoid; surface polished. Head with 

 only the outline of the occiput visible cephalad of the pronotum; 

 eyes separated by nearly twice their width; antennae in length 

 exceeding the body. Pronotum transverse; cephalic- and lateral 

 margins regularly arcuate, very faintly flattened dorsad of the head, 

 caudal margin arcuato-truncate. Tegmina slightly more than one 

 and one-half times as long as the pronotum, reaching to the base of 

 the fifth abdominal segment, broad, the 

 greatest width subequal to the length of the 

 pronotum and contained one and one-half 

 times in the tegminal length ; costal margin 

 very gently arcuate, strongly rounding 

 distad to the broadly rounded distal margin, 

 sutural margin nearly straight; marginal 

 field broad and short, anal field subpyri- 

 form, the anal sulcus reaching the sutural 

 margin nearly two-thirds the length of the 

 latter from the base; venation cHstinct, 

 discoidal vein wdth six rami toward the 

 costal and disto-costal margin. Wings 

 minute. Abdomen from near the base Fig. l. — Ceratinoptera 

 narrowing in width distad; supra-anal plate f^y/j'o'i.^ToTt^pe: 

 transverse, moderately produced mesad, (x 3.)
