ON THE SPECIFIC DISTINCTNESS OF HALISIDOTA HARRISII, 



WITH NOTES ON THE PREPARATORY STAGES OF THE SPECIES 

 OF HALISIDOTA INHABITING NEW YORK. 



BY HARRISON G. DYAR, YOSEMITE, CAL. 



As is well known, two kinds of Hal- 

 isidota larvae inhabit the Atlantic states, 

 differing only in color and in their food 

 plants. Both were noticed by Harris, 

 and the form with black hair pencils 

 was figured by Smith and Abbot as H. 

 tessellaris. In 1S63, Walsh separated 

 the forms as distinct species, indistin- 

 guishable in the imago, and gave the 

 name H. karrisii* to the form with 



*At first he gave the name antiphola to the form with 

 black hair pencils, Proc. Bost. soc. nat. hist., IX, 2SS >

orange hair pencils that is found on the 

 sycamore. In Grote's list of 18S2, har- 

 risii is given as a dimorphic larval 

 variety of H. tessellaris, and so it has 

 been considered. However, it seems to 

 be a fact that harrisii occurs only on the 

 sycamore and tessellaris ne/er on that 

 tree, so that if the former is a variety of 

 the latter, the variation must be due to 

 the influence of the food-plant ; but I 

 have recently observed that the larvae 

 differ in their first stage, and it is hardly 

 to be supposed that the food-plant would
