MELAMPSALTA PARVULA SAY. 
This interesting little species has been taken once at Ames 
and this is, so far as I know, the only record of its occurrence 
in the state. It is a more southern form, being credited to the 
southern states as far north as southern Illinois and central 
Kansas. Very likely it may be found occasionally in the south- 
ern part of the state when collectors become more plentiful. 
Any addition to these records will be gratefully received and 
duly credited in future records. 
BIOLOGIC NOTES ON CERTAIN IOWA INSECTS. 
HERBERT OSBORN AND C. W. MALLY. 
The following notes are extracted from Bulletin 32 of the 
Iowa Experiment Station, and embrace such portions of work 
upon certain injurious insects as have a biologic interest. We 
are indebted to the Experiment Station for the use of the 
figures. 
THE GROUND CHERRY SEED MOTH. 
{Gelechia sp.) 
Our attention was called to this insect by Dr. J. C. Milnes, 
of Cedar Rapids, who reported it as very destructive on wild 
ground cherries under cultivation; writing further, that this 
cherry being very prolific and of excellent quality would be a 
desirable garden plant were it not for the great injury from 
this pest. The specimens sent contained the insect in the pupa 
stage. 
Cultivated ground cherry at Ames suffered from similar 
attack, and the pest seems likely to occasion much loss. 
Examination of wild ground cherries in the vicinity of Ames 
revealed a considerable injury from the pest, and steps were 
taken to secure the early stages and determine as fully as pos- 
sible the habits of the insect. 
Out of 1,000 berries examined 130, or 13 per cent were 
infested. All of these infested berries contained the pupae 
enclosed in a white silken cocoon which filled most of the 
cavity of the berry, the seeds being entirely devoured. Near 
the stem end of the berry and opposite the head of the pupa 
was an opening presumably prepared for the emergence of the 
moth.
