ENTOMOLOGICAL SOCIETY 
3518ST MEETING 
The 351st meeting of the Society was held October 5, 1922, at the New 
National Museum, with President Ganan in the chair and 36 persons 
present. Mr. L. J. Borrimer was elected to membership. 
E.G. Rernnart: The life history and habits of the solitary wasp, Philanthus 
gibbosus. This paper was discussed by Messrs. Bripwett, Howarp, 
RouweEr, and ALDRICH. 
Dr. Baker opened a discussion on the use of the common names “grass- 
hopper” and “locust,” in which Messrs. CaupELL, Watton, Howarp, 
Hystop, AutpRicH, Batt, HEInRicH, Ronwer, BarBER, GAHAN, and Brip- 
WELL took part. The consensus of opinion was that the name “grasshopper’’ 
rather than “locust”? should be used. 
Wo. Scuaus exhibited 5 moths and 1 larva of Zelotypia stacyi Scott; 
Phassus triangularis Hy. Edwards, a female with a specimen of the larva; 
Phassus giganteus Hen. Schaeff.,a male and female. The larvae and pupae 
of these insects move up and down through long galleries. Larvae of Phassus 
triangularis live within the stems of a species of the ash family in Mexico, 
and in many cases trees are honey-combed by their galleries. Larvae of 
Zelotypia stacyz live in a similar manner in eucalyptus branches. 
352D MEETING 
The 352d meeting of the Society was held November 2, 1922, at the New 
National Museum, with Dr. L. O. Howarp in the chair and 47 persons 
present. 
In the first address of the evening Prof. C. P. Lounssury, of the Union 
of South Africa, gave an account of entomological work in South Africa. 
The Imperial Bureau of Entomology with headquarters at London is 
maintained by the cooperation of South Africa, Canada, New Zealand and 
other British dependencies and is a clearing house for determinations and 
entomological information for the British Colonies. Entomologists have 
been appointed to various colonies north of South Africa but these have no 
connection with the Union of South Africa. One function of the Entomo- 
logical office of the Union is to enforce the various quarantine acts and for 
this purpose an entomologist is stationed at each of the principal ports. 
These men play the part of guardians against the importations of dangerous 
insects or plant diseases. Another duty of the division is the general super- 
vision of the insecticides and fungicides, a work similar to that done by the 
U. 8. Department of Agriculture. The Division looks to Washington for 
guidance and assistance and often models its rules, regulations, and policies 
after the U. 8. Federal Bureau. 
The paper was discussed by Messrs. ALpricH, ScHwarz, and Howarp. 
Prof. Utrich DauucRen, professor of biology at Princeton University, 
spoke on the luminosity of insects. He said that luciferene works similar 
to the blood. He is looking especially for the species of fire flies which have 
green lights along their sides and red lights in the head. He is also studying 
the reversing of the light process. The light produced is over 994 per cent 
pure and without heat.
