TROMBIDIUM. 3 
Body rhomboidal, broadest between the coxe of the second and third pairs of legs; 
scarlet, velvety ; the frontal part of the cephalothorax forming a sort of fleshy clypeus, 
which covers the basis of the palpi; a few transverse furrows run across the dorsal 
surface of the living animal. The coxe are inserted on the sides of the body; the first 
and second pairs, which are grouped near together, widely separated from the posterior 
coxe formed by the third and fourth pairs of legs. The first and fourth (?) pairs of legs 
are longer than the second (?) and third, each thickly covered with short velvety hairs. 
Front tarsi spindle-shaped, bearing two very small claws on the top; the other tarsi 
obliquely truncate, their claws almost simple. The palpi bear long pinnate hairs, which 
on the third and fourth joints are arranged into rows; the appendicula is lancet-shaped 
and bears on its surface several long setaceous hairs, which, however, are rather shorter 
than in 7. mexicanum. 'The mandibles are short and terminated by a short, broad, 
falciform claw, the inner edge of which is denticulate. 
This species is found amongst dead leaves in the forests round Retalhuleu. The 
description and figures were made from the living animal. 
4. Trombidium quinque-maculatum, sp. n. (Tab. IV. fige. 1-1.) 
Corpus oblongo-ovoideum, depressulum, tomentosum; nigrum, maculis quinque albis dorsalibus: harum ante- 
riores pares, magne, triangulares, regionem humeralem utriusque corporis lateris occupantes ; reliquee 
tres macule impares, seriem formantes longitudinalem in dorso medio; ex his anterior parvula, rotunda, 
in dorsi centro sita; huic proxima macula impar magna, ovalis, in abdomine medio sita; in abdominis 
apice macula magna transversa impar. Apex frontalis cephalothoracis lineolam longitudinalem, brevem, 
flaveolam insupra exhibens. Pedum par primum et quartum longa, crassiuscula, secundo et tertio pari 
multo longiora, flavescentia, ab articulo tertio usque ad sextum nigrescentia. Palpi flavescentes, pilis 
nigris sparsis induti; appendicula lata, late inserta. Mandibule? 
Long. 2, lat. 0°75 millim. 
Hab. GuatEMALA, near the city (Stol/). 
Body oblong, a little depressed, with a longitudinal furrow on each side; velvety 
from closely-set, short, thick, quadrifid hairs: colour deep black, with five white 
spots; these spots are arranged as follows—two, lateral, large and triangular, occu- 
pying the region between the bases of the second and third coxe; a small round 
one nearly in the centre of the dorsal surface between the apices of these; a larger 
ovoid one, placed between the centre and the end of the dorsal surface; and a large 
transverse one on the posterior end. ‘The first and fourth pairs of legs are very long, 
about the length of the body, considerably longer and stouter than the second and 
third pairs; their colour is ochraceous-yellow, which from joints 3-6 merges into 
blackish, owing to the short, pinnate, black hairs by which this part is clothed. Palpi 
ochraceous. 
I found one specimen of this richly-coloured species amongst shrubs in a ravine 
near the city of Guatemala; it was running about in the bright sunshine. Unfortu- 
nately, I accidentally lost the mounted preparation of the mandibles before I had drawn 
and described them.
