_ Boll weevil develops on Althea buds under cage conditions.--R. C. 
Gaines, Tallulah, reporting on the development of boll weevils on malva- 
ceous plants other than cotton, says: "Three female boll weevils devel- 
Oped in and emerged from Althea buds during the month--1 on September 
12, 1 on September 17, and 1 on September 19. On August 15, 10 pairs of 
newly emerged weevils were released in a cage over an Althea plant. 
These weevils had emerged from cotton squares collected for parasite 
studies and were not permitted to feed on cotton before being released 
in the Althea cage. On August 29 practically all. buds and blooms had 
fallen to the floor of the cage. These fallen forms, about 40 in nun—- 
ber, were collected on August 29 and placed in a small screen wire cage 
in the insectary for observation. On September 12 the first female wee- 
vil emerged from one of these Althea buds. The second female emerged 
On September 17, and the third female on September 19."

Calhoun and assistants, Presidio, Tex., report observations of Pectino- 
phora gossypiella Saund. as follows: "Four complete generations and a 
partial fifth generation of the pink bollworm had completed development 
on cotton squares at Presidio, Tex., up to September 350, while two and 
a partial third generations had completed development in bolls at that 
date. The average longevity for third square brood females was 8.50 
days and 13.90 days for those of the second boll brood at mean tempera— 
tures of 81.97°F. and 77.58° F., respectively. For males of the. third 
square brood, the average longevity was 7.33 days at a mean temperature 
of 83.88° F. Longevity records on males for the second boll brood were 
not complete on September 30," 
Survival of pink bollworm in Texas flood.—-Mr. Calhoun and assist- 
ants also observed that "Approximately 50 per cent of the larvae in green 
bolls on the cotton plants which were submerged by flood waters from 56 
to 60 hours were killed. Live larvae in floating open bolls were recov— 
ered after the bolls had been in water 192 hours. No live stages were 
found after this period of time, In open bolls that had been submerged 
a few live larvae were found after 96 hours but none after this period 
of time. Live stages were recorded in floating green bolls 240 hours, or 
10 days, after being placed in the water. In bolls allowed to remain 14 
days in water no live larvae were found, Half of the bolls in water at 
the end of 14 days were floating." 
INSECTS AFFECTING MAN AND ANIMALS 
Observations on the "whip scorpion" or "vinegarroon."--0, G. Bab- 
cock, Sonora, Tex., reports that "A live vinegarroon was kept in captivity 
for 262 days. During this time it was fed many soft—bodied insects. The 
hard-shelled sowbugs and beetles were refused. The vinegarroon was less 
active during the winter, feeding only at approximately monthly periods 
until it died on June 30, 1932. The method of protection was by means 
of a gaseous secretion of acetic acid (vinegar) from the tail, hence its 
appropriate local name 'yinegarroon.' I would suggest dropping the name 
‘whip scorpion,' as this arthropod is not a scorpion."
