PHIL^US MEXICANUS Nov. Sp. 



Plate I, figure 18. Plate II, figure 18. 



$ . Total length 10 mm. Width of abdomen 3.1 mm. 



Cephalothorax: length 4; width 3.2; height 2. 



Legs 8.3, 6.4, 6.4, 7.8; patella and tibia of the first, 3.4; patella and tibia of 

 the third, 2.8: patella and tibia of the fourth, 3.2; metatarsus and 

 tarsus of the fourth, 2.4. 



Ocular area occupying nearly two-fifths of cephalothorax, one-third wider 

 than long; anterior row of eyes very little curved; lateral one-half 

 as large as middle eyes, separated from them by one-half their own 

 diameter; middle eyes sub-touching; dorsal as large as lateral eyes, 

 equally distant from each other and the lateral borders. Clypeus a 

 little inclined, one-fifth as high as the middle eyes. Falces stout and 

 rather long, inclined forward, and somewhat diverging. Maxillae 

 parallel, enlarged and rounded at extremity; labium two-thu-ds as 

 long as the maxillee, pointed. Sternum convex, nearly as wide as 

 long, truncated in front. Anterior coxas separated by scarcely the 

 width of the labium, much the stoutest and longest. First legs much 

 the stoutest. 



Coloration: Cephalothorax dark brown in the thoracic region, and black- 

 ish on the cephalic plate; the lower margin has a fine black line be- 

 tween two fine white lines; there is a wider band of white hairs 

 which passes around the face and extends on the sides, below the 

 second and third rows of eyes, to the posterior margin. Dorsum of 

 the abdomen bronze brown; a httle behind the middle are four white 

 dots, two on each side. Around the base is a wide white band; on 

 each side, opposite the dots, is a large white spot; on each side, near 

 the apex, is a short, wide, ribbon-hke white band, extending from 

 below on to the dorsum, and bifurcating at the end; this makes a 

 diamond-shaped figure of the bronze color, which connects a small 

 bronze-colored region at the apex with the larger region of the same 

 color on the anterior part of the dorsum. First and second pairs of 

 legs darkest in color; all the legs brown, banded with blackish; tibia 

 of the first leg black with a fringe of black hairs below. Clypeus 

 covered with gray hau-s. Falces dark brown. Mouthparts, coxae, 

 sternum, and venter, brown, thinly covered with gray hairs.
