shelf-like expansion so that the two wings are continuous. 

 Genital and anal openings large and widelj^ separated. Legs 

 moderate; ungTies tridactj'le, dactyles subequal. 



Type species: J. tuherosa 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 

 pteromorpha? united with a broad shelf-like expansion from 

 the anterior margin of the abdomen. It differs from Pelops in 

 having stout, chelate chelicerae instead of long-drawn-out, 

 minutely chelate chelicerae; in having all of the abdominal hairs 

 setiform instead of some of them being spatulate, as well as in 

 other characters. 



Jugatala tuherosa 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. Lamella? small, of equal width 

 throughout their length, about one-half as long as the cephalo- 

 thorax; lamellar hairs long, straight, jiectinate, extending to 

 the tip of the cephalo-thorax. Translamella almost as long as 

 one of the lamellae, usually about one-half as broad as one of 

 the lamella'; at times it is almost obsolete, being broken in the 

 middle. Interlamellar hairs subequal and similar to lamellar 

 hairs, Imt slightly curved, divergent, situated slightly inward 

 and in front of pseudostigmata. Pseudostigma cup-shaped ; 

 jtseudostigmatic 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. 

 Alidomen depressed, almost as broad as long. Pteromorphae 

 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 jirojection which unites the two pteromorphae or 

 wings, which I will call the interalar i^iece, is quite broad; its
