ON THE WHITE EUCLEID^E AND THE LARVA OF 
CALYBIA SLOSSONLE (PACKARD). 
PLATE V. 
By Harrison G. Dyar, A. M., Ph. D. 
There are in Europe and Asia a number of moths colored white or 
nearly so, belonging to the family Hypogymnidae (Lymantriidae=Lipar- 
idse). In the earlier days of the description of American species, several 
kinds were found superficially resembling them, which were therefore 
described as Liparidae and are still listed so in Kirby’s catalogue, though 
really presenting fundamental differences. However, as early as 1882, 
Dewitz showed that one of the larger species was a Eucleid from an ex¬ 
amination of a cocoon, and, some ten years later, Packard was led to 
the same conclusion in describing one of the smaller species which Mrs. 
Slosson had then just discovered in Florida. 
T. he species are all subtropical, inhabiting regions where not much 
entomological work is being done; but fortunately one of them extends 
into our country and I was able to discover the larva, the characters of 
which confirm the opinions of Dewitz and Packard. They are here 
presented at length. 
I have examined Grote’s types of Phyrne immaculata and Euproctis 
pygmcea, sent me by Dr. Skinner. There is no question but that the 
former is Packards Eupoeya nivalis. Grote’s type bears the cocoon 
and number 229. This particular specimen was not sent me, but Dr. 
Skinner states that it is a female, which accounts for the non-pectinated 
antennae. Two specimens with the same labels “Cuba” and “Dr. 
Wilson ” were sent.
