ON THE WHITE EUCLEIDiE AND THE LARVA OF 

 CALYBIA SLOSSONIiE {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- 

 idae). In the earlier days of the description of American species, several 

 kinds were found superficially resembling them, which were therefore 

 described as Liparidse 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. 



The 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 iinmaciilata and Euproctis 

 pygmcea, sent me by Dr. Skinner. There is no question but that the 

 former is Packard's Eupceya 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.
