having lost an internal flange and with weak serrulations of ventral 

 margin visible only under very high magnification.^^ 



Head with occiput ochraceous-buff, a broad band of prouts 

 brown between the eyes, the ventral margin of which is broadly 

 concave, succeeded by a slightly broader band of white, in which 

 laterad are located the ocellar 'spots and the ventral margin of 

 which is transverse, below this the face is heavily suffused with 

 prouts brown, the remaining portions ochraceous-buff, with flecks 

 of prouts brown below the antennae, which send an oblique ray 

 toward the median portion of the face. Antennae ochraceous-buff, 

 with slight suffusions of darker on the three proximal segments. 

 Maxillary palpi ochraceous-buff, the last joint tinged with tawny 

 and becoming cinnamon brown distad. Pi'onotum with lateral por- 

 tions transparent, very faintly tinged with buff"; disk ochraceous- 

 buff, beautifully and heavily pictured with cinnamon brown, as fig- 

 ured. Tegmina transparent, very faintly tinged with buff. Dor- 

 sal surface of abdomen blackish brown and cinnamon brown, with 

 lateral margins irregularly bordered with ochraceous-buff and three 

 rows of irregular spots of the same color. Cerci ochraceous-buff, 

 ventral surface and dorsal surface proximad suffused with prouts 

 brown, the latter with a fleck of prouts brown meso-distad. Limbs 

 ochraceous-buff, the cephalic femora delicately margined dorsad 

 and all the dorsal spines of the tibiae with flecks at their bases of 

 prouts brown. Abdomen with ventral surface bordered narrowly 

 laterad with light ochraceous-buff, this margined internally with 

 prouts brown, within which is a fleck of the same color on each seg- 

 ment, remaining portions ochraceous-buff, ecxept for a broad medio- 

 longitudinal band of blackish chestnut brown, which expands caudad 

 on the subgenital plate. 



Length of body 7, length of pronotum 2.1, width of pronotum 3, 

 length of tegmen 2.7, width of tegmen 2.1 mm. 



In addition to the type, a large immature male bearing the same 

 data and a smaller immature individual from Ceres, Santa Fe, 

 Argentina, are in the Hebard Collection.

The species has been once previously recorded from Argentina, 



by Rehn from the Misiones. The male genitalia are here figured 



^^ The specialization of the tarsal claws was not recognized at the time the 

 genus Cariblatta was described. It is apparent that in degenerate forms this 

 specialization is much reduced or obsolete. In delicatula and other long-winged 

 species, a flange, minutely but conspicuously serrulate, is foimd, but in lutca lutea 

 and lutea minima this has entirely disappeared, leaving no trace even of ser- 

 rulation.
