REPORT OF THE DIRECTOR 1920-21 39 



Entomologist has been keeping records of galls described subsequent 

 to the appearance of the Key in the hope that a revised edition of 

 this bulletin might be issued. 



Publications. Owing to delays, the reports for 191 8 and 19 19 

 have not appeared and the publications of the Entomologist have 

 been restricted to various popular articles relating to injurious 

 insects, such as a special folder on " Corn Borers and Grass Insects," 

 a brief summary of the " European Corn Borer and Call for General 

 Control," issued as Circular 199 of the Division of Agriculture, 

 Department of Farms and Markets, and several technical papers on 

 gall insects, mostly exotic, and published in Indian and African 

 journals. 



Collections. A number of desirable additions to the state 

 entomological collections have been made during the year, some 

 of the best material being reared in connection with studies of insect 

 outbreaks or secured as a result of requests for information concerning 

 previously comparatively unknown forms. Special attention has 

 been paid to the acquisition and preservation of immature stages, 

 since these are very difficult to obtain; this is particularly true 

 of a number of borers similar to the European corn borer and found 

 in corn or in the stems of various plants. The special work upon 

 the European corn borer has resulted in numerous very desirable 

 additions to the state collections. 



D. B. Young, assistant entomologist, donated from his personal 

 collections of earlier years a large series of Coleoptera consisting of 

 648 specimens belonging to 369 species previously unrepresented 

 in the state collections. This large addition has necessitated the 

 rearrangement of many of the Coleoptera and in addition it has 

 involved the study and identification of numerous obscure species. 

 This work has been prosecuted in addition to many identifications 

 for correspondents and other routine duties: 



Office matters. The correspondence the past season has required 

 much attention, especially that in relation to the European corn 

 borer. The usual routine as outlined above has fully occupied the 

 time of various members of the staff. The assistant entomologist, 

 as heretofore, has been in charge of the office and responsible for 

 correspondence and other matters during the absence of the 

 Entomologist. 



The special work on European corn borer authorized by the last 

 Legislature necessitated the temporary transfer, effective June 1, 

 1920, of Mr Young to take charge of the work and the appointment 

 of W. H. Hoffman to fill the temporary vacancy. Hall B. Carpenter
