INSECTS AFFECTING THE CATALPA. 
Catalpa bignonioides. 
AFFECTING THE LEAVES. 
1. The Catalpa sphinx. 
(Plate XXXVIII). 
Sphinx catalpa? Boisd. 
Order Lepidoptera ; family Spiiixgid.e. 
An account of this sphinx by Prof. Riley (with an excellent plate) 
which we are kindly allowed to reproduce, appeared in his report as L\ 
S. Entomologist for 1882, p. 189. 
The caterpillar frequently defoliates the Catalpa, though usually a 
very rare insect. It differs from others of the family in laying its eggs, 
sometimes 1,000 in number, in a mass on the leaves or stems or branches: 
the larvae being at first gregarious. At Atlanta, Ga., there are three 
or four broods during the summer ; the last brood hibernating in the 
pupa state beneath the ground, the moth appearing in March. In sum- 
mer it is six weeks from the time the egg is laid till the moth appears. 
AFFECTING THE PODS. 
2. The catalpa-pod diplosis. 
Diplosis catalpce Comstock. 
The following account is taken from Professor Comstock's report for 
1880: 
In the early part of August the unripe and normally green pods of the Indian bean 
(Catalpa birjnonoides) upon the Department grounds were noticed in many cases to 
have partly turned brown in a strange manner, one-half or more of the pod remain- 
ing green, while the remainder appeared to be dry and of the color which it usually 
has when ripe. Upon opening one of these abnormal pods the mass of seeds was 
found to be fairly tilled with active, footless little yellow maggots, none of them 
more than 3.25 nim long. When disturbed they wriggled from the pod and fell to the 
ground, or bringing the two ends of the body together and suddenly straightening
