are very repulsive to the sight and afford excellent germinating places 

 for destructive fungi, which are always abundant. The tumors are 

 often scarcely perceptible in height, while many protrude one fourth of 

 an inch. The opening is usually about one eighth of an inch in 

 diameter. The larviB are small, rarely attaining a length of more than 

 one fourth of an inch. They are light yellow or whitish, and have the 

 head, two small spine areas on the dorsum of the prathorax, two similar 

 areas on each of the mesothorax and metathorax, and the tip of the 

 abdomen dark brown. The body is covered with many colorless hairs, 

 which are not visible to the unaided eye. 



The adult moths,- as previously stated by Prof. Baker, are of two 

 distinct sizes, the largest being three eighths of an inch long and the 

 smaller about half as large. The general color is light grayish-brown, 

 with large and distinct dark marking upon the front wings. The body, 

 legs and antennfe are light, as are the hind wings, which have large 

 marginal fringes. Under certain lights there is a bright blue iridescence 

 to the color of the wings and body. 



As there is apparently no way of importing this pest except with the 

 fruit, the danger of introducing it to California is greatly reduced by 

 the quarantine laws which are being maintained against all countries 

 where the fruit flies (Trypetidce) are known to exist. However, the 

 recognition of such a pest by quarantine inspectors may prevent its 

 nitroduction from some other section of the world where these laws do 

 not apply.
