shelf-like expansion so that the two wings are continuous. 
Genital and anal openings large and widely separated. Legs 
moderate; ungues tridactyle, dactyles subequal. 
Type species: J. tuberosa n. sp. 
This genus is distinct from all other forms except some of 
the species of the genus Pelops C. L. Koch in having the 
pteromorphe united with a broad shelf-like expansion from 
the anterior margin of the abdomen. It differs from Pelops in 
having stout, chelate chelicere instead of long-drawn-out, 
minutely chelate chelicere; in having all of the abdominal hairs 
setiform instead of some of them being spatulate, as well as in 
other characters. 
Jugatala tuberosa n. sp. 
(Fig. 4) 
Color medium brown; appendages paler than the body. In- 
tegument of moderate thickness, granular. Cephalo-thorax 
almost as broad as long. Lamelle small, of equal width 
throughout their length, about one-half as long as the cephalo- 
thorax; lamellar hairs long, straight, pectinate, extending to 
the tip of the cephalo-thorax. ranslamella almost as long as 
one of the lamella, usually about one-half as broad as one of 
the lamelle; at times it is almost obsolete, being broken in the 
middle. Interlamellar hairs subequal and similar to lamellar 
hairs, but slightly curved, divergent, situated slightly inward 
and in front of pseudostigmata. Pseudostigma cup-shaped; 
pseudostigmatic organ short with a short pedicel and a globose 
head. Two pairs of tectopedia present, one pair for the first 
and one pair for the second pair of legs; first pair long, shovel- 
like; second pair short, projecting, somewhat saucer-like. 
Abdomen depressed, almost as broad as long. Pteromorphe 
extending for about one-half the length of the abdomen, trun- 
cated anteriorly, and each bearing dorsally a single, short, 
curved seta not far from its anterior margin. The transverse 
shelf-like projection which unites the two pteromorphe or 
wings, which I will call the interalar piece, is quite broad; its
