136 U.S. NATIONAL MUSEUM BULLETIN 25 6 



In the Uvalde cages, the adults commenced to hibernate in October, 

 were dormant during November and December, resumed active 

 feeding in January, and deposited eggs in February and March. 



Narnia femorata Stal 



A species larger than N. pallidicornis, with greatly dilated hind tibiae 

 and a white cross band across the elytra, specimens were found com- 

 monly on prickly pear fruit at Zacapa in Guatemala, La Union in 

 El Salvador, and Tegucigalpa in Honduras in November-December 

 1927. In Mexico, it was found in San Luis Potosi and Chapinga on 

 0. robusta and 0. megacantha (Bennett 1963). 



LEPTOGLOSSUS Guerin-Men^ville 

 Leptoglossus dentatus Berg 



Identified by H. G. Barber (in litt.) as a cactus feeder, this species 

 has a wide range in the Argentine and occurs in Uruguay. Our records 

 give the following distribution in Argentina, Provinces of Buenos 

 Aires (Carmen de Patagones and the Sierra Ventana), Entre Rios 

 (Concordia), Corrientes (Paso de Los Libres), Santiago del Estero 

 (Anatuya, Villa Angela Bandera), Tucuman (Tapia), Jujuy (Jujuy), 

 Cordoba (Cruz del Eje), Catamarca (Catamarca, Recreo, and Ad- 

 naigala), La Rioja (Chilecite), and Mendoza (Mendoza); and in 

 Uruguay at Salto and Piriapolis. 



Both adults and larvae attack the fruit and more rarely the joints of 

 various Opuntia, including 0. bonaerensis and related monacaniha types, 

 sulphured, quimilo, utkilio, and glomeraia, as well as many forms of cerei, 

 such as Trichocereus and Stetsonia. The eggs are laid along the spines 

 after the manner of Chelinidea, and are not placed end to end as in 

 the case of Narnia pallidicornis. 



Leptoglossus ductus (Herrich-Schaefifer) 



A Brazilian species identified as a cactus feeder by W. L. McAtee 

 (in litt.), it has been collected at Rio de Janeiro and Macae in the 

 State of Rio de Janeiro, Queimadas and Joazeiro in the State of 

 Bahia, and B6a Vista, Belem, and Rio Branca in the State of Per- 

 nambuco. Adults and larvae attack the fruit and joints of Cereus and 

 Opuntia, including 0. monacaniha at Rio de Janeiro and the dwarf 

 0. inamoena in Bahia and Pernambuco. The larvae are gregarious 

 and the result of their injuries on the joints resembles the work of 

 Chelinidea vittiger in Texas.
