Latindia argentina new species. 



Type: <^; Misiones, Argentina. January 14, 1910. (P. Jorgen- 

 sen.) [Acad. Nat. Sei. Phila., type no. 5231.] 



Apparently closer to L. pusilla Saussure and Zehntner (Biol. 

 Cent.-Amer., Orth., I, p. 112) from Tarma, Peru, than to any other 



member of the genus, agreeing in having the 

 ulnar vein similarly ramose, toward the costal 

 margin, but differing in the pronotum being more 

 transverse elliptical with no truncation to the 

 caudal margin, In the more numerous costal veins 

 to the tegmina, in the subreniform shape of the 

 anal field of the same and in the non-annulate 

 antennae. 



Size small; form elongate elliptical; texture of 

 surface coriaceous, largely short pilose. Head 

 with entire width of vertex visible cephalad of pronotum, the outline 

 of occiput subtruncate; eyes large, interspace between them slightly 

 greater than the depth of a single eye; antennse moniliform. Pro- 

 notum transverse elliptical, the greatest length contained about one 

 and three-eighth times in the greatest width; cephalic margin 

 subtruncate, caudal margin gently arcuate, not at all truncate; a 

 distinct medio-longitudinal sulcus present on almost the entire disk, 

 the latter subimpressed and defined caudad by a subrectangulate 

 indentation, the surface of the disk with about four pairs of oblique, 

 very low strumose ridges; lateral portions of the pronotum sub- 

 deflected, the margins there distinctly cingulate. Tegmina elongate, 

 surpassing the apex of the abdomen by more than a third of their 

 length, their greatest width (at distal third) 

 contained nearly three times in their greatest 

 length; costal margin very gently arcuate, distal 

 margin rather narrowly rounded, sutural margin 

 nearly straight; costal veins about fifteen in 

 number, ulnar vein sending three rami toward 

 the costal and distal margins, anal field abbre- 

 viate, occupying less than a third of the tegminal 

 length, anal sulcus arcuate, oblique adventitious 

 vein and impressed sulcus decided. Wings reach- 

 ing to the tips of the tegmina. Subgenital plate 

 broad, ample, with short lateral styles; cerci 

 elongate, articulate.
