Ceutorhynclius n. sp. This weevil breeds in the crown of Selenia aurea and is parasitized by Catolaccus incertus. Baris cuneipennis Casey. This weevil breeds in the roots of Helenium tenuifolium and is parasitized by Catolaccus incertus. Orthoris crotcJiii LeConte. This Lower Sonoran weevil breeds in the seed pods of Mentzelia nuda. It is parasitized very higldy by Microbracon nuperus, Eurytoma tylodermatis, and a species of Tctrastichus. TricJioharis texana LeConte. This species breeds very abundantly in stems of Solanum rostratum, and is hence more or less a Lower Austral insect. Its parasites are Cerambyco- bius cyaniceps, Eurytoma tyloder- matis, Microbracon sp., and Sigal- PHUS CURCLXIONIS. TricTioharis trinotata Say. The po- tato stalk weevil (fig. 25) breeds in the stems of many Solanaceae, includ- ing SoJanum carolinense, S. melongena (egg plant), S. rostratum, S. tuberosum (potato), Datura stramonium, D. tatula, PJiysalis longifolia, P. pMladel- pJiica, P. lanccolata, P. heteropliijUa, and P. virginiana ambigua. It is known to be parasitized by Sigalphus clticulionis and Eurytoma TYLODERMATIS. Tricliobaris compacta Casey. Tliis weevil breeds in the pods of Datura stramonium and is also recorded as breeding in Datura mete- loides. It is parasitized by Cerambycobius cyaniceps, Myiophasia -enea, and Pediculoedes Fig. 25.
