so have had to omit some of them, but the characters specified 
above will enable this genus to be recognised readily. The 
minute insect on which it is founded is one of the most remark- 
able species I have seen and seems to have no near ally previously 
named, and I am in doubt where it should be placed. <A casual 
glance would at once suggest placing it near Myllena but its 
much shorter palpi and short stout antennz seem inconsistent 
with such a place; I can however suggest no better. Its most 
remarkable character I think consists in the relation of its head 
and prothorax to each other which is almost exactly as in Cory 
lophus, the small head being in repose laid back flat against the 
under-surface of the prothorax so as to be entirely invisible from 
above, and the outline of the prothorax being evenly semicircular 
so that there is no. trace whatever of any front angles. The 
front part of the prothorax moreover is roundly declivous in front 
and when the head is laid back underneath projects freely over 
it exactly as in Corylophus. Another very notable character is 
found in the general form (which is an extreme exaggeration of 
that of Myllena) - the prothorax and elytra are exactly applied 
to each other so that their outline is perfectly continuous and 
forms a wide oval; the slender Conurus-like hind body looks like 
a thin tail and when it is raised upward the body has much the 
appearance of that of a miniature scorpion.
