NOTES ON THE AMERICAN SPECIES OF OLENE HUBNER. 



[Lepidoptera; Liparidse. ] 

 BY HARRISON G. DYAR. 



I have been asked for an exact determination of the pine- 

 feeding species of Olene {Parorgyia) of northern distribution. 

 It appears that the material before me is insufficient for a full 

 comprehension of the subject. Especially material is needed 

 from the Southern States, while a certain well-marked type of 

 larva has never been associated with its proper adult. I have 

 formerly reduced the number of species considerably, admit- 

 ting but three in Bulletin 52, U. S. National Museum. I 

 think that the number will have to be somewhat increased. 

 I will consider the names in the order of Bulletin 52. 



FEEDING ON DECIDUOUS TREES. 



Olene achatina Smith and Abbot. 



I have no material before me agreeing exactly with Abbot's 

 figure. The form shown is like obliquata, with more of white, 

 the brown markings distinct and broken into spots. It may 

 be a southern race of obliquata, or distinct. The larva fig- 

 ured may be wrongly associated. It is very unlike the larva 

 of obliquata as determined by Seifert and others. A larva 

 agreeing with Abbot's figure has been bred by me, producing 

 the form basiflava. 



Olene obliquata Grote and Robinson. 



This form, with its variety parallela G. & R., has been 

 well worked out by Seifert. The adult is characterized by 

 the subterminal markings of the fore wing, while the larva 

 is very distinct, its long, dense hairs showing no contrast in 

 the tufts of joints 5 to 8, only a single pair of hair pencils in 

 front, none behind, and none accompanying the tuft on joint 

 12. The distribution of the material before me is from Maine 

 to Maryland. I have placed this form as a synonym to 

 achatina, which can only be maintained if Abbot's larva is 

 wrongly associated. New material from Georgia is needed 

 to settle the point. 



Olene tephra Hiibner. 



I have no material agreeing certainly with Hiibner's figure. 

 In the male 'no white is shown, in the female only a little 

 around the discal mark. The resemblance is toward obhquata, 

 but the inner line is too distinct and its parts too well marked 

 and separate, besides the distinct markings on the hind wing
