Further Notes on British Oribatidas. By A. D. Michael. 7 



the two pairs of immensely long setiform hairs, which spring from 

 the edge of the abdomen, are also bent down upon the ventral 

 surface, instead of being folded, and there form a diagonal cross. 

 The whole arrangement may be most distinctly seen through the 

 existing skin, pending one of what, for want of a better name, I 

 call the inter-nymphal ecdysis, i. e. a change of skin which does not 

 take place upon any transformation, but simply upon the nymph 

 growing larger. I have luckily succeeded in mounting a specimen 

 in this condition which shows the whole arrangement admirably. 

 I have not figured it from want of space. 



New Species. 



Among the unrecorded species described and figured below are 

 one or two which may be worthy of some remark, although I have 

 not any very striking novelty to record this time. 



In my paper published in the third volume of this Journal, 

 page 186, at the end of the description of the nymph of Leiosoma 

 palmicinctum, I stated that I had brought home what I had 

 supposed to be several very young specimens of that nymph found 

 upon the golden lichens growing upon the rocks of the Land's 

 End, but that, when examined with a higher power, they turned 

 out to be a different species, the shape being slightly longer, and 

 the nervures of the palmate hairs irregularly furcate instead of 

 reticulated. I also stated that they had not attained the adult 

 condition, and that I doubted their surviving the winter; that 

 doubt became considerably stronger as the winter advanced, for my 

 captives became to all appearance dead, and I feared that the only 

 thing to be done with them was to mount them as specimens. I 

 was still unwilling to abandon a hope, however remote, of tracing 

 the species, and my patience was in this case rewarded, for, as the 

 spring advanced, the apparently dead nymphs began to move about 

 very slowly, and finally underwent their last transformation, and 

 there emerged an adult, which was new to me, and I believe 

 unrecorded, and which was moreover quite distinct from anything 

 I had seen, and was a handsome species. The interesting part 

 was, however, that, although the two nymphs resembled each 

 other so closely that it required a careful examination with a 

 moderately high power to find out the difference, and although 

 they were utterly different from all other known nymphs, and 

 notwithstanding that they came from the same place and both fed 

 upon lichen, yet the images were quite dissimilar, and not in any 

 way to be included even in the same genus. Palmicinctum is a 

 Leiosoma, and the present species, although it does not fit very 

 well into either of Nicolet's genera, yet is certainly a Cepheiis, 

 unless a new genus were made for it, which does not seem to me to
