In the desert regions of the Northwest a small lizard {Phrynosoma 

 douglasii douglasii, fig. 8), locally called the "sand toad," eats the 

 adult Elateridse in large numbers. A pair of these small lizards 

 kept in the insectary would eat Corymbites infiatus beetles as fast 

 as these could be fed to them. That this is a large part of their 

 natural food is evidenced by the contents of the stomachs of three of 

 these lizards collected at Govan, Wash., on April 24, 1910. In the 

 stomach of lizard No. 1, 60 per cent of the food was ants, 8 per cent 

 click-beetles, and 30 per cent other beetles; in lizard No. 2, 90 per 

 cent was click-beetles and 10 per cent ants ; and in lizard No. 3, 75 per 

 cent ants, 15 per cent click-beetles, and 10 per cent other beetles. 

 Several other kinds of these lizards inhabit the more southern desert 

 lands of the West and are usually called " horned toads " in these 

 sections. 



In rearing cages wireworms are often infested with small mites 

 (Tyroglyphidse). The writer received a shipment of Melanotus 

 larvse from Inman, Nebr., in April, 1912. This material when re- 

 ceived was apparently free from any vermin. When examined again, 

 on June 17 of that year, some of the larva? were found to be badly 

 infested with these mites in the hypopial stage. The mites were so 

 close together on the last two segments of the wireworms' bodies that 

 they gave the impression of an incrustation. On June 24 all the 

 wireworms were infested with these mites. Mr. Pergande also found 

 these mites on larvse of Melanotus communis in his cages at Wash- 

 ington, D. C, in March, 1900. 1 Mr. Banks is of the opinion that 

 these mites are not attacking the wireworms, but merely make use of 

 insects as a ready means of dispersal. He is evidentty correct in
