the blades of the forceps (cercopoda), the largest tooth on the 
inside of the left blade being situated nearer the middle. Our spe- 
cies is also smaller. The number of joints to the antennæ in ¥. 
subterraneus are 32; in the Mexican species 40. 
Associated with the Japyx and in equal abundance was a Sco- 
lopendrella, which I at first supposed to be a different and larger 
species, but which, after a careful microscopical examination, I 
cannot separate from S. immaculata Newport. It has the same 
general appearance; and the form of the antennæ and number of 
antennal joints are nearly the same; there being 40-42 joints in 
the Mexican, and 35-36 in a Kentucky individual, The number 
of scutes behind the head is the same (16), and their shape exactly 
the same. The anal cerci are slightly longer than in United 
States specimens, but the fine setae are the same in size and 
arrangement. The specimens are pure white and larger (5™™) 
than any I have yet seen from the United States. 
Campodea mexicana, n. sp—While Scolopendrella immacu- 
lata seems to be common to Europe, the United States, and 
Mexico, and Campodea staphylinus Westw., likewise common to 
Europe and the northern United States, we discovered at Cor- 
Ova, in company with the foregoing Synaptera, a very distinct 
Species of Campodea, which is apparently characteristic of the 
Herra caliente or warm zone of Mexico. 
It is a large species, the body 4™™ or 7™™ including the caudal 
Stylets, being but little smaller than C. cvokei Pack., of Mammoth 
and adjoining caves, but with much shorter caudal appendages, © 
The body is shorter, the three thoracic segments being shorter 
than in C. cookei. The antennz are of the length of the body and 
28-jointed ; the terminal joint is intermediate in shape between C. 
Staphylinus and C. cookei, being slenderer than in C. staphyinus,
