SS8 OUSK iXPtOOPTCBA 



The eggs are drposilcd on the twigs of trrr« in clusters, and are hatched in July. By the 

 flnt uf Septriiiber, or ns Intr a<i the iiiiddlc, the cut(T|>iIliir ae()Bires its full siz4-, wiirn it 

 measun"« nii«>ut two mid a <|iuu-ter inches : it is nalicd, of a grrrn color, nnd ninrltrd l>y 

 aix or riehl •nmll dnrii warts, and is I'urni.shi'd with a pair of .otmple coral-rtd spines for 

 the second and third rini;!i. Then- is a short spine u|>on the lust ring but our, and the last 

 is fiirnished with alvjut »\x short hlack bristles. 



The lilac seems to l>e the favorite shrub to which the prometkeus attaches its cocoon, 

 which is aliout an inch long, and gray like l>aper : it is attached longitudinally to a leaf, 

 that .serves to pn>lect and conceal it. 



This moth is one of the most common in and alx)Ut Albany, some lilacs furnishing as 

 uiany us a dozen c«jc»ons. The cateri>illar, ihoiigh not perhaj'S entirely harmless, yet in 

 this rj-sfiect .scarcely deserves attention. Ilir large moth*, appt-aring late in the season, 

 alter thi« It'uVfs are fully grown, do n<.i s«eiii us injurious as they niiglit U- if tlxj nrrivid 

 when the leaves were ex|>unding and temler ; and trees do not sulfer !>o much tn>u\ the 

 loss of foliage in the early autumn, as in the spring. 



CcRATocAMrA REG.\Lis ( llurris). Rtgal Walnut-moth. 



"Antenna* short, and, in the males, pectinated on both sides ; In the females, thread-like. 

 Wings without h'M.lis : forewings olive-colored, ornamented with several yellow sjiots, 

 and vcine<l with broad retl lines.'' 



This inst-ct I have not yet seen : it is fully descrilx-d by Mr. IIahhis, and, according to 

 his description, it is one of the linest and largest of our moths, having an expanse of wing 

 equal to six inches. The larva; are s]>inous, but harmless ; that Is, they do not sting when 

 handled. Wlien fully gn>wn, it Is four or five inches long and three-fourths of an Inch in 

 diameter, and of a green c<)lor bunded with pale blue transversely*. It feeds on the walnut. 



The moth is said to ujipear in June, and is more rare than the Dryocampa imptrialu. 



From the old family of UoMuvcioAior Salumians, Dr. Hahris has separated the Ctrato- 

 cam}Hi and Dryocampii,SiUt\ a Hw others, nnd has constituted a new family under the name 

 of C'EaATocAMPAUJi;, alter the name of the chief genus contained in it : the niuue signifies 

 homed caterpUlart. On the second, and sometimes also ou the third ring, lhe>e horns arc 

 stifTer, more rigid and curved, agreeing more i)erfeclly with their definition as Acrai. 



All the sjiccies here referred to feed upon the leaves of forest-trees : they go into the 

 grounil where they undergo tlieir tran.-formutions, and this without making cocoons. The 

 chrysalides are notched or toothed, with the design of assisting their uaccnt from the 

 gruuod at liie lime just prior to their final and last change.
