with the web ; they were kept in a dark cupboard in a room with a 
fire, but far from it. The first larvae were hatched on (3th of April ; 
they are hexapod, with the rostrum rather longer than in the adult ; 
they have the fan-shaped hairs, but not distributed in quite the 
same manner ; there is a row of seven near the edge of the body, 
but only two at the posterior end instead of four, and the two anal 
hairs and those on the mammillary processes are larger and more 
spatula-shaped than in the adult ; those on the palpi are the same, 
but the hairs on the legs are mostly less broadly flabellate than in 
the adult. Each hair of the first two pairs of the back seems to 
have a separate motion and to be moved at the will of the creature ; 
the first joint of the palpi is less massive, in other respects the 
appearance is similar to the perfect form. 
I have not found much difficulty in keeping them alive in glass 
ring cells with a little of material where they were found and a 
thin cover over. They require to be kept in separate cells, and 
supplied with food (for which cheese mites answer), and a slight 
moisture kept in the atmosphere, but not too much. 
I propose to call it Flabellifer, from the fan-shaped hairs, unless 
it shall turn out to have been found before.
