METAFECENIA. 307 
1. Metafecenia albolineata, sp.n. (Tab. XXXIII. fige. 16, 16a, , ¢; 
17, 17a, ¢.) 
Type, ¢, in coll. Godman & Salvin. Total length 12 millim. 
Legs 1,4, 2,3. Colour yellow-brown ; carapace with a very narrow line of white hairs running down the centre, 
two short ones on each side of the ocular area, and a broad submarginal band of white hairs. Abdomen 
pale olive-green, paler beneath, with two broken parallel lines of white hairs running from the anterior 
margin almost to the spinners. Legs unicolorous yellow-brown; sternum paler. 
Tibia of palpus with a tuft of long hairs beneath ; one-half longer than the patelle, slightly curved outwards, 
with a short, stout, black, blunt, apical spur, directed almost at right angles to the segment on the outer 
side. Tarsus nearly as long as the tibia; bulb with a stout curving spine, directed forwards, on the outer 
margin ; the inner side of the bulb being produced into a stout lobe, its apex bifurcate, with another dark 
spine lying beneath its apex, this spine also lying within the concavity of a diaphanous white membrane. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
Fam. DICTYNIDA. 
Tarsal claws three. Cribellum present, usually (but not always) divided in the centre by a narrow septum ; 
calamistrum consisting of a long double or single series of curved bristles extending from near the base 
either to the middle point or almost to the apex of the inner side of protarsus iv. Legs with or without 
spines. Eyes in two more or less parallel rows, subequal, varying in their relative position, 
The spiders belonging to this family spin an irregular web over the surface of the 
walls of outhouses, on wooden palisading round gardens, or amongst the leaves of 
shrubs, the heads of rushes and grasses, under bark of trees, &c. The habit of Dictyna 
parietalis is precisely similar to that of D. uncinata, so common on wooden palisadings 
and amongst the foliage of trees and shrubs in England and on the Continent. 
Two genera only have been recorded from Central America, Dictyna and Temecula ; 
but I have also given the characters of Thallumetus, E. Simon, and Ciniflo, Blackwall, 
in the Table, for the sake’of comparison. They may be distinguished as follows :— 
GENERA, 
a. Calamistrum consisting of a single row of curved bristles extending 
from about one-fifth from the base almost to the apex of pro- 
tarsus iv. Legs (of females, at all events) devoid of spines, 
1. Posterior row of eyes slightly recurved . . . . . . . . Dicryna, Sund. 
2. Posterior row of eyes slightly procurved. 
a’, Central posterior eyes nearer to each other than to the 
laterals 2... ww. ek ek kk Temecua, O. P.-Cambr. 
b’. Central posterior eyes further from each other than from 
the laterals. 2. 2. 2. 2. 1, » 2 o+ . 4 . . [THattumetus, E. Simon.] 
6. Calamistrum consisting of a double row of curved bristles ex- 
tending from about one-fifth from the base to scarcely beyond 
the middle of protarsus iv. Legs very spinose in both sexes . [Crn1FLo, Blackw.] 
Nore.—I do not know Thallumetus and have assumed that in the characters drawn from the calamistrum 
and the armature of the legs it resembles Dictyna— cui valde affinis et subsimilis est,” according to Simon,
