Peclcliam — Spiders of the Family Attidae. 283 



spiders. The first row is curved, the middle being less than 

 twice as large as the lateral and a little separated from each 

 other, while the lateral are separated from them by from one- 

 third to two-thirds of their own diam^eter. The second row is 

 about twice as far from the third as from the first row. The 

 dorsal eyes are as large as the lateral and form a row which is 

 plainly narrower than the cephalothorax at that place. 



The genus Phidippiis has many species in I^orth and Central 

 America, and we have one species from South America. It 

 was formed by C. Koch in 1846, the type being variegatus from 

 IN'ew Orleans, Die Arachn. XIII, j)- 125. In our Attidae of 



North America we cited variegatus as a synonym of morsitans 

 Wlk., but since then we have received large collections from 

 Mexico and Texas and are satisfied that it is distinct. Mexi- 

 canus P., and Honmrdii P. (PL XXIII, fig. 5), are also very 

 close to variegatus (PI. XXIII, fig. 4). 



The descriptions and drawings of P. ooscuriis and P. Rau- 

 terhergii, in our paper on Xorth American Attidae, were made 

 from badly rubbed specimens and give but an imperfect idea 

 of these species. We therefore redescribe their coloration from 

 perfect specimens which we have recently received from Texas. 



Mr. Workman's'^ drawing of the type of Thorell's genus 

 Megatimiis (PL XXIII, fig. 2), drew our attention to the fact 

 that this genus strikingly resembled Phidippus. Mr. Yfork- 

 man very kindly sent us a specimen of the spider in question 

 and we find that it conforms in all respects to Phidippus. 



After an exchange of fresh specimens, Mr. Emerton agrees 

 with us that his P. midtiformis is distinct from our P. rufus, 

 P. midtiformis, rufus and richer are close together but their dis- 

 tinguishing characteristics are brought out in the key. 



Mr. Xathan Banks, in Arachnida from Baja California, 

 Proc. Cal. Academy of Sciences, Third Series, Vol. I, Xo. 7, 

 1898, described several new species of Phidippus. He has 

 kindly sent us specimens of these. We think that his P. fune- 

 hris belongs in the genus Parnaenus. P. fraternus we believe 

 to be identical with Philaeus chrysis Wlk., and P. disjunctus 

 is the same as our Philaeus fartilis. 



^Since the above was written aracbnology has suffered a great loss in the 

 death of Mr. Workman.
