SOME ARACHNIDA FROM NEW MEXICO, 

 BY NATHAN BANKS. 



The following list of New Mexican Araclmida is based chiefly 

 on material collected during the past few years by Prof. T. D. A. 

 Cockerell. A few species were collected by his wife and son. 

 Prof. C. H. T. Townsend, when connected with the New Mexico 

 Agricultural Experiment Station, collected and sent to me a small 

 lot of spiders from the vicinity of Las Cruces. The late Mr. 

 Hugo Soltau sent me a very interesting collection from Albu- 

 querque, containing a number of forms not taken by others. I 

 have added the few species recorded by other writers from Nevv 

 Mexico, but not seen by me. 



The total sums up to 148 species, nineteen of which appear to 

 be new and are here described. The leading groups may be 

 tabulated as follows: 



Araneida, 123 



Phalangida, 6 



Pseudoscorpionida, 3 



Scorpiouida, 2 



^. Solpugida, 3 



Acax'ina, 11 



Total, 148 



The spiders are included in seventeen families; the leading 

 family in point of numbers is the Attidoe with twenty- tAvo species; 

 the others are : Thomisida) with sixteea, Thei'idiidte with sixteen, 

 Epeiridse with thirteen, and the Lycosidse with ten species. Of 

 especial interest are the species of Paehylomerus, Meriola, Corlnna, 

 Oxyopes, Fuentes and Taraais. The list shows many northern as 

 well as southern forms. The species of Northern distribution are 

 mostly from Beulah and Las Vegas. The Southern forms come 

 mostly from Mesilla and Las Cruces. Of the species of northern 

 distribution, many of which occur across the northern part of 

 our country, attention may be drawn to the following forms :
