Described from i 9 and 5 , beaten from Xanthoxylum at 

 Logansport, L/ouisiana, June 6, 1906, by the writer. Type $

ZYGOBARINUS n. gen. 



This genus is proposed for Zygobaris coelestinus L/inell, which 

 differs notably from the two species now included in Zygobaris 

 and from the closel} 7 related species in Zygabaroides. 



CALANDRIDAE. 

 RHODOBAENUS Lee. 



Rhodobaenus ij-punctatus 111. That variety or species with 

 the five thoracic spots, and four lateral and two median elytral 

 spots was bred by the writer, at Dallas, Texas, from the 

 stems of Xanthinm commune. Larvae, pupae and adults were 

 found in the stems Aug. 4th and i5th, and adults Sept. nth. 



ANTHRIBIDAE. 



BRACHYTARSUS Sch. 



Brachytarsus alternatus Say was bred in large numbers from 

 the stems of Sideranthus rubiginosus at Dallas, Texas, in 

 August. The eggs are laid in the tip of a new side stem or at 

 the base of a flower head ; the larvae feed in a small space, 

 surrounding themselves with the brown powdery exuviae in 

 which they pupate. The breeding is continuous. 



PARASITES. 



Microdontomerus anthonomi Cwfd. (det. J. C. Crawford). 

 One specimen was bred as a primary parasite by F. C. Pratt 

 from material collected at Mexia, Texas, September 29, 1905.
