Harris's pine hawk moth 

 Laparci honthycoidcs Walk. 

 A grass-green, yellow and white striped caterpillar feeds on pine in the middle of 

 September, the moths appearing the following June. 



This caterpillar is interesting largely because of its peculiar appear- 

 ance, its striking color rendering it inconspicuous on pine needles. The 

 young larva is remarkable because of its large, high head terminating in a 

 conspicuous cone. Just before the last molt the head is triangular, conical, 

 the body thick and stout. It is then green with yellowish and red stripes. 



The full grown larva is green like that of the pine leaves, and has the 

 broad, brick-red dorsal stripe wanting on the prothoracic segments and rep- 

 resented by patches on the two following. This band is bordered with a 

 whitish yellow line. There is a lateral straw yellow line and a broad white 

 line becoming yellow anteriorly, below the spiracles. This larva may be 

 easily recognized by its conspicuous striping. 



White pine tufted caterpillar 

 PaiitJica furcilla Pack. 

 A dull red caterpillar banded with brighter red, with a light lateral line and reddish 

 hairs in clusters, occurs on pine during late August and in September. 



This species is not common. The larva, when full grown, measures 

 about 1 5/^ inches in length. It has been described by Dr Packard as 

 follows : 



The body is black, with sparse, dull, light yellow hairs radiating from 

 dark or pale mamillae. A pair of long prothoracic straight tufts projecting
