Pabricius appears to have first identified cJiaracias, Bose, with 
urtiem , Lin., but apparently he was not very sure, for he uses the 
latter only as synonym of the former, which he still keeps, with an 
expression of doubt, as a Coccus. (S. 1L, p. 311.) 
Of De Greer’s species the figure is rude and unsatisfactory, but 
the description, as follows, is sufficient to denote our species : — 
“ Ce sont un grand nombre de flocons cotonneux en forme de lames feuillet<5es 
plates d’un blanc eclatant, qui couvrent tout le dessus du corps et le debordent m6me 
de tous les cdtes ; ces lames, qui sont un peu courbecs, y sont placees tres-reguliere- 
ment, se couvrent un peu les unes les autres, ou arrangees comme des tuilleB ou 
comme les ecailles des poissons ; il y en a d’abord une couclie au milieu du corps, 
plus courtes que les autres et ari’angees sur deux lignes, de faejon quo celles de l’une 
de ces lignes xont rencontrer celles de l’autre rang par leur base, et elles represented 
ensemble comme une petite feuille decouple. Les autres lames placees de deux 
cotes de la tete jusqu’ au derriere, et formant deux rangs distincts, sont beaucoup 
plus longues que celles du milieu, comme je l’ai dit, debordant le corps considerable- 
ment, et elles sont toutes un peu courbees et dirigees vers le derriere.” 
Zetterstedt described urticcc in order to point out the differences 
between it and his chiton. 
The descriptions of Coccus uva, Modeer, and Dorthcsia Celavauxi, 
Thibaut, both referred to this species by Signoret, I have not been 
able to see. 
Burmeister ( l . c .) refers “ Coccus glechomce, Pabr.” (without 
further indication), to the genus Dorthesia , as a distinct species, but I 
cannot find the description. 
The male is described as of a light brown colour, smaller than the 
female, elongate ; the head, thorax, and abdomen distinct ; no rostrum ; 
the antennae very long, filiform, 9-jointed ; wings, two (anterior), long, 
pale-greyish, with two longitudinal nervures (Westwood says there 
are also two minute halteres, terminated by a short seta) ; the abdomen 
at its termination with a pencil of long, fine, white hairs. The geni- 
talia are of peculiar form. 
The male, according to the observations of its original discoverer, 
as given by Amyot and Serville, op. cit., p. 623, is polygamous. 
“ It is in the month of September, after the third or fourth moult, that the 
males appear, but only few in number. The author says that it was with much 
trouble that he found four or five of them among a great quantit y of females. More 
slender than these, they arc also more active ; they run with their wings elevated 
from one female to another, and confer their favours according to their caprice. 
After some days of such a course, the male retires to the root of a plant, under a 
stone, where its inactive body becomes covered all over with a very fine cottony 
matter, which has very much the appearance of mouldiness, and there, doubtless, it 
dies. The females have one moult after coupling, they soon after retire into the
