116 ARANEIDEA. 
Maxille short, rounded at the extremities ; /abiwm short, about half the length of the maxille. These parts 
are yellowish-brown, tipped narrowly with pale whitish. 
Sternum small, and of a reddish-brown hue. 
Abdomen large, the upperside elevated, almost perpendicularly, in a somewhat subcylindrical form, to a great 
height ; it leans forwards, however, over the cephalothorax. The length from its pedicle to the spinners 
is but a little over 2 lines, from the spinners to the highest extremity nearly 7 lines. On the posterior 
side, about two-thirds of the way to the summit, is a strong hump or prominence, with two small 
subconical eminences, one on each side of it in a transverse line. ‘The summit is broad, bluff, and has on 
its posterior edge two subconical eminences, larger than those on the lower hump, and placed also in a 
transverse line. The abdomen is of a pale yellowish-brown colour, clouded for the most part with 
blackish ; it is mottled thickly with whitish on the lower part of the sides, and in parts has numerous 
very short more or less clavate black hairs. The spinners are short and compact. The genital process 
is prominent, not very large, somewhat rounded, of a deep red-brown hue, and with a small, somewhat 
flattened, curved epigyne bending over backwards from its fore extremity. 
Hab. Muxico, Teapa in Tabasco (H. H. Smith). 
Mr. Smith has the following note on this spider :—“I found it struggling in the 
grasp of a wasp which was stinging it; it had let itself down wasp and all from a mass 
of brush and dead sticks near the bank of the river edge of the forest. The peculiar 
form and colour of the spider is evidently a protective resemblance ; when sitting on 
the end of a dry stick of about the same diameter as its own body it would have the 
appearance of a broken end of the stick itself; or if sitting on the side of a stick the 
abdomen would appear like the stump of a dead branch broken short off diagonally. 
I have found several curious longicorn beetles which are protected in the same 
9 
way. ‘The above observation is no doubt a just one, but evidently the protection 
afforded against the wasp was not very efficacious. 
MIAGRAMMOPES, Cambridge. 
Miagrammopes mexicanus, sp. n. 
Adult female, length 43 lines. 
In form and general structure this spider is entirely normal. 
The cephalothorax is oblong, its length nearly double its breadth, the four corners rounded ; the sides project 
over the sternal surface in a kind of flap; the upper surface (looked at in profile) is somewhat flattened 
and the middle of the clypeus is a little projecting. It is of a black-brown colour, clothed with fine short 
grey hairs. 
The eyes are small, four in number, two in a rather oblique transverse line on each side of the caput forming 
a long curved line whose convexity is directed forwards. They are seated on tubercles, that of the 
exterior eye on each side being much the strongest. (Monsieur Simon, Hist. des Araignées, 2nd ed. 1892, 
p- 217, states that both Dr. Berkan and himself have discovered in this genus two or four additional 
_ eyes, exceedingly small and generally only to be seen under microscopic power. I cannot find these in 
the species [ have as yet examined. It is, however, possible, and indeed probable, that these will be 
found in some species and not in others ; they are evidently in different degrees of evanescence, having 
probably passed, or are passing, through the various stages of disuse, atrophy, indistinctness, and final 
disappearance.) 
The legs are very disproportionate in relative length, those of the first pair greatly the longest and strongest, 
those of the third pair the shortest and weakest, and the second almost the same; the first pair are as long 
as or longer than the entire spider, the fourth, which are next in length, a little longer than the abdomen, 
and furnished with a strong calamistrum at least two-thirds of its length on the upperside. The tarsi
