2. Xylina laticinerea Grt. 



This green fruit worm was represented among the specimens 

 received from each locality, and, in one or two instances, it seemed 

 to be equally as numerous as the preceding species. 



The moth of X. laticinerea was first described and named in 

 1874 from a Massachusetts specimen. The insect is illustrated 

 on plate 2, figures f and g representing the moth, natural size 

 and twice natural size, respectively. It seems to differ from the 

 moth of X. antennata in the ground color of the wings being of 

 a more decidedlj^ ash-gray colo>r and the markings are possibly a 

 little more distinct; a comparison of the figures of the two species, 

 shown on plates 1 and 2, will show that they are very similar. 

 There may be antennal and genitalic differences in the males also; 

 having bred no males of laticinerea, we cannot verify this. 



Nothing has been recorded respecting the life-history or earlier 

 stages of this species; the caterpillar described by- Mr. Edwards 

 (^Papilio, III, 135) as belonging to this insect, was certainly an- 

 other species, probably X. grotei, as we shall see later. Our ob- 

 servations show that the caterpillars appear in May with, and 

 have the same habits as, those of X. antennata. Pupation takes 

 place in earthen cells in the soil about the same time in June. 

 But the caterpillars of X. laticinerea spin no trace of a cocoon. 

 The insect remains in the pupa state until fall, when some of 

 them give forth the moth, but in our cages most of the pupae are 

 now hibernating; one moth emerged September 26th. The fol- 

 lowing table, made up from the recorded captures of the moths 

 this species, shows that they fly both in the fall and spring, many 

 of them doubtless hibernating and others not emerging until 

 spring.
