FOODS^ HUMAN NUTEITION". 665 



together information on the Hawaiian sugar-cane insects. Particular attention 

 is given to the biology of, and remedial measures for, 4 of the more important 

 pests, namely, the sugar-cane leaf hopper (Perkinsiella saccharicida), the 

 Hawaiian sugar-cane borer (Rhabdocnemis [Sphenophorus'l obscurus), the 

 Hawaiian sugar-cane leaf-roller {Oniiodes accepta), and the sugar-cane mealy 

 bug {Pseudococcus calceolaria;). Brief mention is made of miscellaneous 

 insects and rats injurious to sugar cane in Hawaii. 



Papers on insects affecting stored products, F. H. Chittenden ( U. S. Dept. 

 Agr., Bur. Ent. Bui. 96, pt. 2, pp. 19-28, figs. 4)- — Descriptions of the broad- 

 nosed grain weevil and the long-headed flour beetle are presented. 



The broad-nosed grain weevil (Caulophilus latinastcs) (pp. 19-24). — This 

 weevil, first described from Florida in 1831, appears to be permanently estab- 

 lished as an enemy of dried cereals and other food materials in the United 

 States, having been recorded or received from Qeorgia and South Carolina as 

 well as Florida, and from Jamaica, Porto Rico, Mexico, Guatemala, and Madeira. 



A bibliographical list of 14 titles is included. 



The long-headed flour beetle {Latheticus oryzm) (pp. 25-28). — This beetle 

 was first described in ISSO, having been found in rice from Calcutta and else- 

 where, including England, and being also known from Arabia, Norway, Italy, 

 and from a London granary in samples from Bussorah, Persia, and Odessa, 

 Russia. Quite recently it has been introduced into this country, having been 

 collected at Houston, New Braunfels, San Antonio, Galveston, Fort Worth, 

 Lyons, Wichita Falls, and Dallas, Tex., and Detroit, Mich. Thus it is estab- 

 lished in Texas, and probably in Michigan, and bids fair to become a pest in 

 time. 



A bibliographical list of 10 titles is given.
