"We first notice that the plant looks sick, it ceases growing, gradually ttirns pale 

 yellow in color and finally withers up and dies. About 25% of all our seedlings at 

 one time seemed to be affected, however, not all of these have died yet."** 



"This is the first time we ever had trouble with this pest. It is entirely new to 

 us." 



"**Nothing else in our Nursery is affected." 



"We have examined hundreds of seedlings and these maggots have been found 

 in the seed only, none feeding on the stem." 



"***A small quantity of seed from the same pit, planted about 15 days earlier 

 than the main crop on the land adjoining, and not more than 1% of these were 

 affected.***" 



No further reports of any additional infestations have been received.

The Stanford Collection of Coccidae. The already extensive collection of Coc- 

 cidae in the Department of Entomology at Stanford University, has received some 

 very important additions dtu-ing the past year. Mr. A. H. HoUinger has gener- 

 ously given to the department his collection of Coccidae from Texas, consisting of 

 approximately 1000 lots. The work that has been done on this collection shows 

 that it contains many interesting and important species. 



Mr. O. E. Bremner, County Horticultural Commissioner for Sonoma County, 

 and Mr. R. S. Woglum for many years connected with the Bureau of Entomology, 

 now Entomologist for the California Fruit Growers Exchange, have both loaned 

 their extensive collections of Coccidae to our Department in order that they may 

 become available for study by specialists in this group. These collections represent 

 the results of many years work and they are especially valuable because 

 they contain so many species from various parts of the world. The Bremner col- 

 lection is of particular interest from the presence in it of type material of numerous 

 species described by Maskell and Cockerell. 



These, with the collections recently made by Mr. Ferris in Lower California and 

 the Southwestern United States, and the material that has been received by ex- 

 change from foreign coccidologists, make the Stanford Coccid collection second in 

 importance in the Uuited States only to the National Collection at Washington. 

 The types of all of the species that have been described (approximately 100) from 

 this laboratory, are deposited here. 



The work of publishing the results of the studies on the collection is being, and 

 will continue to be, pushed as rapidly as possible.

An Unusual Type of Injury to Sweet Potatoes in Texas by a Burrowing Bee. 

 July 28, 1920, the writer received word from a farmer in Ricardo, Tex., that a new 

 insect, which resembled a bee, was injioring sweet potatoes and that the pest was 

 present by the thousands or millions. As the grower had not been able to irrigate, 

 the plants were gradually drying up. The writer, upon investigation, found the 

 field alive with bees, swarming in the air and on the ground. Many were just emerg- 

 ing from the soil while others appeared to be ''digging in." The ground in spots 

 was honeycombed with burrows made by the emerging bees, identified by Mr. S.
