INSECTS AFFECTING THE ORAKGE. 



'^^, 



plate, liowcvor, is Inrger, and shows two imcloi, and is evidently tiTO 

 plates joiiied toijetlier. Antennae C jointed, and proportioned as with 

 C. Floridcims. Less long; lihiae nearly twice as loni;" ns tiir>i ; dijj^itules 

 of the claw very large. The other tarsal pair veiy long and slender, 



but with a very largo bntton. The skin is 

 seen in jdaces to be furnished with many 

 minnte, ronnd, transparent cellules, prob- 

 ably spimicrets (indicated and so called by 

 Sigiioret in his description of C Vinsonii), 

 and along the liorder are sniall groups of 

 the constricted arrow-sh ipe^l tubercles men- 

 tioned in the last species; but the bristle- 

 .Bha]>ed sphinerets seem to be wanting, as in 

 C. Fainnairii Targ. 



" The E<j(/s. — Length, 0.35™™, rather slen- 

 der, little more than a third as thick as long. 

 Color light reddish brown, rather darker 

 than the e^^ of C. Floridensis. 



'•'•Youncj Larva. — Very slender; dark brown 

 in color; legs and antennae as with C. Flori- 

 den sis. 



" Growth of the Insect. — The growth of the 

 insect and the furination of the waxy cover- 

 ing seems to be very similar to that of the 

 last species. Soon after the larva settles 

 the same two dor.-al ridges of white secre- 

 tion make their appearance, but soon split 

 np into transverse bands. Examined on

nor one being in the shape oi a horseshoe. 

 At the same time the lateral margin of the body was observed to be 

 fringed with stift' spines, seventeen to a side. At nine days the small 

 liorse shoe like mass had extended so as to nearly cover the thorax, and 

 the transverse bauds had lengthened and widened until they i)reseuted 

 the appearance of a nearly complete shield to the abdomen, serrate at 

 the edges. Fifteen lateral tufts, such as were noticed in C. Floridensis^ 

 and such as Targioui figuies in the larva of C. rvsci (Stud. Sulle coc- 

 ciniglie, Plate 1, Fig. C) had appeared, though still small. 



"At this stage of growth, as with the last species, all development 

 seemed to stop, altliongh the specimens lived on for months, the tem- 

 peratue in the breeding-room i)robably not being favorable to the for- 

 mation of the i)lates. 



"The smallest specimen in the collect ion with t he plales already formed 

 measures L""^' long by 2""" wide and 1'"™ high. The color is light brown, 

 and the wax has a somewhao translucent appearance. The dorsal plate
