Several specimens from Sierra San Nicolas, Guaymas, 

 and Tepic, Nov. Readily separated from L. directa by its 

 shorter abdomen. Some from Tepic have the front legs 

 and abdomen more reddish than the others. 



190. Azilia mexicana, sp. now 



Plate XV, Fig. 19. 



Length of <5 7 mm.; leg I 26 mm. Cephalothorax pale, with four forked 

 blackish streaks above; mandibles yellow-brown; sternum dark, with a pale 

 central spot; legs pale, with brown rings at the end and middle of the joints. 

 Abdomen dark grayish, with a paler stripe in the center, and a darker stripe 

 each side broken somewhat into spots; venter gray, rather pale in middle. 

 Eye-region sloping, clypeus extremely narrow, both rows of eyes recurved, 

 the M. E. rather larger, and the P. M. E. closer to S. E. than to each other; 

 sternum plainly longer than broad, triangular. Legs long, especially the first 

 pair, with a few long spines; fourth pair plainly shorter than the second. The 

 abdomen rather narrow, high, and convex, twice as long as broad, pointed 

 at tip. The $ palpus has a quite long blunt projection on the tibia; the bulb 

 is rather simple, with a stout, slightly curved style toward the tip. 



One adult male; three immature from Tepic, Nov. Quite 

 distinct from A. gualemalense Cambr. 



191. Chrysometa alboguttata Cambr. ? 



Meta alboguttata Cambr., Biol. Cent. Amer., Arach. Aran., p. 2. 



One immature specimen from Tepic is probably this 

 species: it hardly agrees with Chrysometa, yet is much 

 nearer to this genus than any other known to me.
