Sitona flavescens Marsham breeds in the nodules on roots of 

 Lupinus pusillus at Dallas, Texas. 



Lixus tenellus Casey breeds in the stems of an umbelliferous; 

 plant, causing a gall-like swelling. Like all other Lixus it pupates 

 in the larval cell. 



Lissorhoptus simplex the rice weevil also breeds on the roots 

 of Echinochloa crusgalli in south Texas. The larva is an external 

 as well as an internal root feeder and makes a pupal cell of mud. 



Hyperodes echinatus Dietz breeds in the roots of Senecio 

 lobatus and Plantago media in Texas and Louisiana. Hyperodes 

 solutus Boheman breeds in the stems and scapes of Sagittaria 

 latifolia at Dallas, Texas. 



No records have ever been published of the supposedly rare 

 genus Pnigodes but the writer has several species, one bred from 

 Ptilimnium capillaceum, others bred from Selenia aurea, Lepid- 

 ium and Oenothera laciniata. They are root weevils and very 

 common in Texas. 



Very little has been published on the habits of the genus 

 Otidocepjialus. It is therefore of interest to note that Otido- 

 cephalus arizonicus breeds in the stems of mistletoe (Phoraden- 

 dron flavescens) at Dallas, Texas, and also in Arizona (as hereto- 

 fore recorded). 0. carinicollis Horn breeds commonly at Dallas 

 in the twigs of Bumelia lanuginosa. The adults appear in April 

 and begin to mate. The immature stages require at least until 

 December for development. Hibernation occurs in the larval, 

 pupal and adult stages. It was found parasitized by Eurytoma sp., 

 Ptinobius sp. nov., and Heterospilus sp. 0. chevrolati Horn 

 breeds in the galls of Amphibolips on live oak twigs at Victoria, 

 Texas. 0. dugesi Champion breeds in cynipid galls on oak at 

 Durango, Mexico. 



Oopterinus perforatus Horn breeds in cynipid galls on roots of 

 oak according to Mr. Schwarz. 



Orchestes pallicornis Say mines the leaves of Ulmus alata and 

 U. americana at Dallas, and of Alnus at Falls Church, Va. Each 

 larva makes a. separate mine and pupates in a cocoon in an in- 

 flated portion of the mine. 



Prionomerus calceatus Say mines the leaves of Liriodendron 

 tulipifera, and Sassafras officinale around Washington, D. C., 

 and in Florida mines the leaves of Magnolia. The eggs are laid 

 in the midrib. Several larvae feed side by side making large 

 mines which inflate when dry. The pupal cells are of silk and 

 clustered together. It has been found parasitized at Clarks- 

 ville, Tenn. This species was first recorded from Liriodendron 

 by Townend Glover. 1
