Hab. Mexico, Orizaba (H. H. Smith) ; Guatemata (Sarg 3). 
The female is here noted for the first time, and is in general appearance similar to 
the male. For special characters, see the Table and Plate. This species is evidently, 
according to the drawings of the palpus by Emerton, very closely allied to, if not 
identical with, his Z. spherula. The coloration of the female is, however, constantly 
different, and without a more detailed drawing of the spine at the apex of the bulb of 
the male one cannot be quite sure. The greenish-yellow spot on the abdomen in 
LT. spherula is replaced by a black spot in 7. faceta, while in the latter there are no 
lateral spots at all. These characters may, at the same time, be simply due to individual 
variation. 
If these two forms are conspecific, I cannot regard them as also identical with 
T. tricornis, O. P.-Cambr., 7’. quinquequttata, Keyserl., or Z’. triangularis, Keyserl.

If, as Simon suggests (and, unless the males of each of these forms are decidedly 
different, as seems to be highly probable), 7. tricornis and T. opulenta are conspecific, 
‘then the intermediate form, 7. triangularis, will probably also be synonymous. I 
cannot at present, however, agree that 7. sphwrula is identical with 7. opulenta, 
though it may be with 7. faceta. T. nigrovittata is in all probability the male 
“of T. opulenta: if this is the case, then they are quite distinct from 7. spherula and 
T. faceta. But at present these points cannot be definitely settled.
