articulations; 9th with two similar spines near the apex, the rest of the apical hairs 
considerably shorter than those on the remaining segments. Marginal spines (fig. 8). 
truncated forming large conspicusus groups on the thoracie and abdominal segments, 
but coaleseing in front from the insertion of the anterior pair of spiracles. Anal 
orifice with the normal number of hairs; surrounding this organ is a conspicuous 
fold in the integument presenting a ring-like boundary within which are 10 similar 
long hairs. Legs normal, hairs extremely fine and very long. 
löimbryo larva: Hairs to anal lobes about two thirds the length of the body; 
legs and antennae furnished with very long hairs.

The marked features of this coceid are its obtuse form, the spinose character 
of the antennae, the currious arrangement of the spinose hairs outside the anal orifice;

and the truncated marginal spines. ÖOne cannot, unfortunately give any details 
regarding the cereous external covering, as this had completely disappeared in the 
alcohol; but its morphological characters are suffieiently diagnostie to give it 
specific rank.

unnamed plant. | 
The specimens are all denuded, but although the external characters are 
wanting the structural details agree with those of typical D. longispinus. Sanders 
considers that there is no reason why Linnaeu’s name adonidum should be discarded 
in favour of longipinus Targ. 
I have no objection to such a change, but for economie purpose I consider it 
advisable to retain the latter name for all agrieultural purposes seeing that is has 
been in use for so long a time.
