Coquillett's observations show that individuals hatehed from eggs on 
the 4th of March cast the first skin on the 23rd of April, and underwent 
the last moult on the 23rd of May. Mr. Koebele also reports a ease 
which bears upon this point, and which is interesting as occurring later 
in the season. He placed four newly-hatched larve on a healthy y young 
orange tree, out of doors, August 5. On ee ember 26 two of t 
passed through the first moált. October 10 one more moulted, and o on 
October 23 the fourth cast its first skin. All left the iem after moulting

HABITS. 
e newly-hatched larvæ settle upon the leaves and tender twigs, 
insert their beaks, and imbibe the sap. On passing into the third stage 
they seem to prefer to settle upon the smaller twigs, although a few are

The species differs markedly from most Coccidæ in bein ng active 
during the greater part of its life, pone most of the travelling is done 
by the female immediately after the third molt and by the male just 
before settling to make his cočöai. At these periods they wander up 
and down the trunk and larger limbs until they find some suitable place, 
when they settle down, the male to pupate and the female to insert her
