64. Syspira longipes S/m.—A few specimens, about 10 

 mm. long, from San Jose del Cabo, seem to be this species. 



65. Corinna peninsulana, sp. nov. 



Plate XIII, Fig. 26. 



Length 6 mm.; ceph. 3 mm. long, broad 2.4 mm.; tibia plus patella IV 3.6 

 mm. Cephalothorax red-brown, almost black in the eye-region; mandibles 

 dark red-brown; sternum red-brown; legs reddish or yellowish brown; abdo- 

 men dark gray or blackish, darkest above; cephalothorax clothed with fine 

 short white hair. Cephalothorax rather broad, broad in front, surface, espe- 

 cially forward, finely granulate; anterior eye-row nearly straight; A. M. E. 

 very large, less than one-half their diameter apart, a little farther from the 

 slightly smaller A. S. E. ; posterior eye-row barely procurved; P. M. E. small, 

 nearly twice their diameter apart, and about as far from the equal P. S. E.; 

 mandibles large, prominent, geniculate, granulate in front, fang long and 

 stout; sternum very broad, nearly as broad as long, sides rounded, truncate 

 in front. Legs moderately long and slender, with many fine short hairs and 

 a few spines, one above on tibia IV, four pairs under tibia I, besides a short 

 pair at tip, two pairs under metatarsus I. Abdomen slender and short, sub- 

 cylindric, in <5 with a horny shield at base reaching above to near middle of 

 dorsum. 



A few specimens; San Jose del Cabo. 



66. Thargalia venusta, sp. nov. 



Plate XIII, Fig. 35. 



Length 7.5 mm.; tibia plus patella IV 3.5 mm. The cephalothorax and 

 sternum are yellowish-red, rather blackish on the posterior sides of former; 

 mandibles red-brown, with an elongate pale spot on the tip; anterior 

 legs wholly pale yellowish, posterior pair darker, no bands; abdomen black, 

 with a white band across the base, continued down upon the sides, behind a 

 red stripe giving off, before the middle, a projection each side, which is con- 

 nected to the white mark on the sides; the red stripe is terminated by a white 

 circular mark reaching upward from the tip of abdomen. Anterior eye-row 

 about straight; the A. M. E. nearly their diameter apart, much closer to the 

 A. S. E. ; posterior row procurved; the P. M. E. nearly once and a half their 

 diameter apart, closer to the equal P. S. E.; sternum plainly longer than 

 broad, truncate in front. Legs clothed with black hair; tibia plus patella IV 

 a little longer than cephalothorax. Abdomen nearly twice as long as broad. 

 The epigynum shows two oval cavities, more than their diameter apart. 



One specimen; San Miguel. A very pretty species.
