NOTES UPON SOME TINEID LARVAE. 
BY VACTOR TOUSEY CHAMBERS, COVINGTON, KY. 
Antispila nyssaefoliella and A. cornifo- 
liella, 
I have had specimens of the imagos of 
both of these species in my collections, but 
not at the same time, and therefore have 
not been able to compare them. Dr. 
Clemens notices some minute differences 
between them, but seems to rely more upon 
supposed differences in the maculation of 
the larvae as indicating their specific dis- 
tinction. But these characters are not 
altogether reliable; for the number and 
distinctness of the maculae differ in the 
same individual at different ages, the num- 
ber increasing with the age of the larva 
until it reaches the last larval stage. At 
least, this is the case with nyssaefoliella, 
of which Dr. Clemens says, ‘‘ dark atoms 
along the dorsum; ventral surface with a 
line of two black spots,” though just what 
‘a line of two black spots” may mean, I 
do not know. In a specimen now before 
me there are nine blackish spots behind 
the cervical shield on the dorsal surface, 
and twelve on the ventral surface. Dr. 
Clemens further says that ‘after the last 
moulting the first segment is black, and the 
dorsal spots become a black vascular line,” 
which is certainly incorrect ; for in its last 
larval stage, when taken from its cocoon, 
I have found the larva to be depressed, fat, 
snowy white with the mouth parts tinged 
with ferruginous, but the larva otherwise 
immaculate. It has a single black ocellus 
about the middle of each side of the head. 
The larvae of this genus are completely 
apodal, and in the youngest larvae that I 
have seen the larval trophi were fully de- 
veloped ; that is, they were equivalent to 
the second form of trophi of larvae of Litho- 
colletis, Phyllocnistis, &c.; and I think 
the larvae leave the egg in this stage of 
development, without passing through what 
I have elsewhere mentioned as the first 
form of trophi of the genera above named. 
I have never found more than two exu- 
viae in an Antispila mine, and am not 
certain as to the number of moults before 
passing into the pupa state; it is probably 
not more than two. 
The larva of A. viticordifoliella in its 
last stage is, like that of nyssaefoliella, 
immaculate ; but it is yellowish white, and 
not snowy white like the latter. These 
larvae crawl but little if at all, after cutting 
out their discs. Indeed, from their struc- 
ture, locomotion would seem to be impossi- 
ble, or nearly so.
