NOTES ON SPIDERS FROM PUERTO RICO1
BY ELIZABETH B. BRYANT
Museum of Comparative Zoology
Recently the Museum of Comparative Zoology received a small vial of spiders from the Luquillo Mountains in the eastern part of Puerto Rico, collected by Mr. Harry Beatty, at about 3,000 feet elevation. It is a section of the island from which Dr. Petrunkevitch had little mate- rial when he published "The Spiders of Porto Rico," 1929-1930, so it is not surprising that among the fourteen species, four are new and three others have never been reported from the island before.
The following is a list of the species found. The aster-
isk (*) denotes the first time the species has been re- corded from the island.

Family THERIDIIDE
Genus Allodipoena gen. nov.
Ceplialothorax almost as wide as long, anterior margin about half the greatest width, cephalic portion high, ex- tending on the same level for more than half the length of the cephalothorax and then falling abruptly to the posterior margin, no thoracic groove or depression; eyes, anterior row recurved, a.m.e. separated by less than a diameter, posterior row slightly procurved, p.m.e. largest of the eight, about twice the diameter of a.m.e., separated by less than a diameter, lateral eyes touching; maxilla about twice as long as the labium and inclined; sternum triangular, widest between the first coxae, almost as wide as long, slightly convex, fourth coxae separated by more than a diameter; legs, 1-2-4-3, quite short, with no spines.
Genotype Allodipcena diance spec. nov.
The genus Allodipcena differs from the genus Dipcena by the small anterior median eyes and the quite different quadrangle. It differs from the genus Theridion by the high cephalic portion, the large posterior median eyes, the convex sternum and the relatively short legs. Allodipcena dianae spec. nov.

The male and female differ in size, shape and color markings, but they probably belong together as they have the same three structural characters that are unusual in the Theridiidae, the posterior median eyes the largest, the convex sternum and the relatively short legs. The female is quite conspicuous with the distinct dark markings on the cephalothorax and the abdomen, and the abdomen much wider than long.

Tetragnatha parva is much smaller than the other spe- cies of the genus found in the Caribbean. Like T. tenuis- sima Cambr., it has no spines on the legs, but the most unusual character is the few teeth on the margin of the fang groove, with the absence of the "large tooth'' usually found on the upper margin. The tubercles of the lateral eyes touch at the base, but the eyes are dis- tinctly separated.

Agobardus blandus is probably related to Agobardus tetuani (Petr.) (Emathis), from Tetuan Mountain, near Jayuya and also from Rio Piedra, Puerto Rico. The lat- ter species has five cusps on the plate of the fang groove, and the cephalothorax has a large pale lateral spot each side. The abdominal dark marks also, differ. It is not impossible, - - that each mountain has a distinct species of this genus.

The male and female Habronattus pretiosus have sev- eral characters in common as do several other species of the genus. Both have the eye area covered with scales, white in the male and golden in the female; the legs have the same dark ventral spots on the femora but only the male has the prolateral surface of the first femur flat- tened and covered with white scales. The lateral stripes of iridescent scales on the cephalothorax that end abruptly on the posterior slope are very conspicuous and are common to both male and female. The flattened area on the first femur of the male has not been seen before in the genus and is very conspicuous.
