446 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 3 



The senior entomological laboratory is 28 by 72 feet and has tables 

 for 75 students, and the graduate laboratory will accommodate 

 twenty. 



The building is lighted by electricity and heated by steam from 

 the central heat and light plant of the college. 



The building was constructed from an appropriation of $80,000 

 for its erection, and $15,000 for equipment, this sum also including 

 equipment in zoology. 



Though entomology, zoology and geology are at present located 

 in the building, it is understood that when the growth of the subjects 

 requires it, the last two will be transferred to other quarters, leaving 

 this as the Entomological Building. 



The equipment in entomology includes microscopes, microtomes, 

 and all the other apparatus usually required for such work, and an 

 unusually full supply of books, journals and hterature. 



The dedicatory exercises were held November 11, and consisted 

 of an address by Dr. W. E. Hinds of the Alabama Polytechnic Insti- 

 tute on the history of the Departments of Entomology and Zoology 

 at the college, and the Dedicatory Address by Dr. L. 0. Howard of 

 the U. S. Bureau of Entomology.

[We understand that the excellent address by Doctor Hinds will shortly be pub- 

 lished by the Massachusetts Agricultural College, while the admirable resume 

 of the development of entomological work in this coimtry by Doctor Howard 

 appeared in full in the issue of Science for December 2, 1910. — Ed.] 



SCUTELLISTA CYANEA MOTSCH. 



By H. J. QuAYLE, Southern California Laboratory, Whittier 



Scutellista cyanea Motsch. is the most important insect enemy of 

 the Black Scale {Saissetia olece Bern.) in Cahfornia. This insect was 

 introduced into the state in 1900 by the U. S. Department of Agri- 

 culture through Dr. L. 0. Howard of the Bureau of Entomology. It 

 is now well distributed in all parts of the state where the black scale 

 occurs in injurious numbers. The percentage of scales parasitized 

 also runs very high, amounting in many cases to 75 or 80%. But 

 this varies greatly in different sections and in the same section in dif- 

 ferent years. 



In spite of the frequently high parasitization by Scutellista, the
