THE EGG. 



The egg is of a cream-white color when first deposited and from 

 2.5 to 3 millimeters long, with a diameter about one-third the length. 

 It is elliptical ovate in shape, with one end slightly more pointed 

 than the other. Just before hatching the color changes to yellowish 

 white, when, with the aid of a lens, the embryonic larva is visible. 



THE LARVA. 



The newly hatched larva, after consuming enough of the eggshell 

 to liberate itself therefrom, measures about 2.8 millimeters in length 

 and is of a pale white color, with the exception of the head, which is 

 light brown, with the mandibles darker. 



THE PUPA. 



The pupa is white and ranges from 18 to 22 millimeters in length. 

 Later the color changes to light brown, and just before transforma- 

 tion takes place to chocolate brown. When observing the pupa with 

 a lens the dark-colored spines on each segment are very pronounced, 

 particularly on the dorsum. 



DISTRIBUTION AND HISTORY. 



Oncideres futator has been recorded from the States of Arizona, 

 New Mexico, and Texas, and from Mexico. The species is probably 

 more injurious in Mexico than in this country, as it appears very 

 susceptible to cold, and since breeding takes place during the fall 

 and winter months it apparently could never become a serious pest 

 in localities were the temperature drops much below freezing. 



The following note was published in 1912 ^ at the meeting of the 

 American Entomological Society, October 24, 1912 : 



Dr. Skinner exhibited specimens of Oncideres putator and said that the species 

 was probably rare in collections. If there is a single brood, this might be ac- 

 counted for by their late appearance. The specimens were taken by Rehn and 

 Hebard in Sycamore Canyon, Baboquivari Mountains, Pima County, Axiz., 

 October 6, 9, 1910; Palo Alto ranch, Altar Valley, Pima County, Ariz., October 

 6, 10, 1910; Tucson, Ariz., October 3, 4, 1910; and Snyders Hill, Pima County, 

 Ariz., October 11, 1910. 



Exact localities have also been recorded by Bates :^ Orizaba and 

 Jalapa, Mexico; Belize, Honduras; San Juan, Guatemala; Bugaba, 

 Panama. Mr, Schwarz records the species from Arizona, New Mexico, 

 and western Texas, and the writer has taken it in southern Texas and 

 at Matamoras, Mexico, The species is native to Central America and 

 has come into the United States from Mexico. There are very few 

 data to be found on Oncideres putator, while a considerable amount
