chamberlin: new spiders of the family aviculariidae. 57 



Integument of cephalothorax and legs chestnut; that of the cheH- 

 cerae black excepting for a reddish tinge ventrally along the fringe; 

 labium black proximally. Pubescence of these parts brown and grey 

 intermixed, the grey showing especially on the ventral surfaces of the 

 femora. Bristles brown, paler, greyish, distally. 



Cephalothorax a little longer than tibia + patella IV but decidedly 

 shorter than tibia patella I. 



Eye-tubercle decidedly less elevated and proportionately broader 

 than in L. klugii. Anterior row of eyes viewed from above procurved 

 in such degree that a line tangent to the anterior edges of the median 

 eyes passes through or very near to center of surface of each lateral 

 eye. Anterior median eyes a little smaller than the lateral (ratio of 

 diameters 13:14); less than their diameter apart (10:13); nearly 

 same distance from the lateral eyes. Posterior lateral eyes with 

 diameter nearly equalling that of the anterior laterals from which 

 they are separated by nearly two thirds their diameter. Posterior 

 median eyes with long diameter a little smaller than that of the laterals; 

 closer to the laterals than to the anterior medians. A line tangent to 

 the caudal edges of the two posterior eyes on each side passing caudad 

 of the anterior median eye of the opposite side. 



Cuspules on labium dense and numerous as usual. 



Stridulating spines of coxa I fewer than in L. klugii and not found at 

 distal end of joint; very long and stout, mostly curving, appresscd, 

 acuminate and not at all spatulate, plumose only distally (Plate 4, 

 fig. 4). Plumose hairs dense on trochanter I and also occurring on 

 mesal surface of femur from base well toward distal end. Plumose 

 hairs likewise occurring on trochanter and femur of palpus. 



Female (type). — Length, cir. GO mm. 



Cephalothorax: length 25 mm.; width, 23 mm. 



Differs from L. klugii (C. Koch) in its flatter and broader eye- 

 tubercle; in its shorter cephalothorax as compared with tibia + 

 patella I which exceeds it decidedly whereas it is shorter in L. klugii; 

 in its stouter legs; etc.
