An ExtraS of a letter from the fame hand, May 50« 1671 ^ 
concerning anlnfeB feeding upon HenbaiOj the ho7 rid f melt 
cf which tJ in that creature fo qualified tbsreijf^ as to become 
in fome meafure Aromatical ^ together m^i the €eUur yielded 
by the Eggs of the fame^ fitc. 
Sir, 
YOu may pleafe to annex a late Obfervation to the 
lait I fencyoo: both being chiefly concerning the 
improvement of colours, and from the Infedt-kind. 
There is a Cimex of the largeft fize, of a red colour 
Ipotced black, and which is to be fpund very frequently 
and plentifullyjatleaftin itsfcafonjUponH^w^fl//?-' 1 there- 
fore in my private notes have formerly intitledit, Cimcx 
ruber macuHs nigris d?Jiin^fus fuper jolia Hyofcyami frequens. 
This Infe<St in all probability doth feed upon this plant (on 
which only we have yet obierved it) if not upon the leai^es 
by ftriking its trunk (the note of diftindiion of this kind 
of lnfe(afrom the reft of the Beetle-kinds) into them, 
and fucking thence much of its fubftance , like as other 
forts of Ctmices will upon the body of man, e^r^ yet upon 
the uniluous and greafy matter, with which th^ leaves 
feem to the touch to abound^ It is further Gblervafble,'hat 
that horrid and ftrong fmell, with which the leaves of this 
plant do affedt our noftrils, is very much qualified in this 
Infe<9:^ and in lome meafure Aromatick and agreeable, 
and therefore we may exped: , that that dreadful INarcoJIs^ 
fo eminent in this plant, may likewife be ufefally tzm* 
pered in this Infecfti which we refer to tryal. About the 
latter end o{ May and fooner,you may find adhering 
the upper fide of the leaves of this planr, cerrainob t rg 
Orange-coloured Eggs, which are the Eggs of thislnft<5t» 
Note I . tharihefe Eggs yet in the belly of the Fcmalts 
are white, and are fofomtfjiie after they are layd ^ bur as 
the yourg ones grow near their time of their being 
ha ched, they acquire a deeper colour 5 and are hatched 
€imces^ and not in the difguifc of worn^<.
