83. Dictyna miniata, sp. nov. 



Plate XIV, Fig. 25. 



Length 1 3.6 mm. Cephalothorax pale reddish, paler behind; eyes on 

 dark spots; mandibles reddish; legs and sternum yellowish; abdomen gray, 

 darker above, with traces of pale chevrons. Pars cephalica high, much nar- 

 rower in front; mandibles long, bowed, concave, faintly granulate; legs long and 

 slender, with black hairs, first pair much the largest; sternum nearly as broad 

 as long, scarcely narrowed in front; abdomen about twice as long as broad, 

 pointed behind; palpi stout; tibia very short and with a short tooth above; 

 tarsus slender with a long process around it bearing the style. 



One male; Guaymas. 



84. Dictyna texana Banks. — Two specimens from 

 Tepic. 



85. Dictyna, sp.? One specimen, no locality, with a 

 manuscript name by Dr. Marx, but it is not adult so I shall 

 not venture to describe it. It has a light marginal stripe 

 on the cephalothorax. 



86. Altella polita, sp. nov. 



Plate XIV, Fig. 20. 



Length 4.5 mm. Cephalothorax and mandibles reddish, blackish around 

 the eyes; sternum rather yellowish brown; legs similar, except the patellae 

 which are paler; abdomen dark gray above, with two rows of pale spots in 

 the posterior part, below lighter gray. Cephalothorax rather low, but little 

 elevated in the pars cephalica; anterior eye-row straight; A. M. E. smaller 

 than A. S. E., scarcely their diameter apart; posteriorrow slightly procurved; 

 P. M. E. once and a half their diameter apart, as far from the equal P. S. E.; 

 mandibles geniculate at the base; sternum plainly longer than broad, sides 

 rounded, pointed behind. Legs rather short, with many hairs, one spine 

 below on metatarsus I and II, three below near tip of tibia III, one at middle 

 and two at the tip of tibia IV, several on the posterior metatarsi. Abdomen 

 twice as long as broad, rounded at base, scarcely pointed at the tip, slightly 

 depressed. The epigynum shows each side a dark curved mark, and in 

 front a pale round opening. 



One female; no locality. The genus differs from Dic- 

 tyna in having spines on the legs, and in the smaller A. M. E.
