 ZYGOBARINTJS n. gen. 



This genus is proposed for Zygobaris coelestinns Linell, which 

 differs notably from the two species now included in Zygobaris 

 and from the closely related species in Zygabaroides. 



CALANDRIDAE. 

 RHODOBAENUS Lee. 

 Rhodobaenus ij-piuiciaius 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 Xanthium commune. Larvae, pupae and adults were 

 found in the stems Aug. 4th and 15th, and adults Sept. nth. 



ANTHRIBIDAE. 



BRACHYTARSUS Sch. 

 Brachytarsus alternatiis Say was bred in large numbers from 

 the stems of Sideranthus rtibiginosus 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.
