Eijes. — First row a little shorter than the second, the lateral eyes 

 slightly lower. Eyes of second row largest, nearly their diameter 

 apart. Third row widest, its eyes a little nearer the second row 

 than each other. Dorsal eye area about one-fifth the length of the 

 cephalolhorax. 



Form. — Superior spinnerets twice the length of the inferior. 

 Cephalothorax in front one- third its greatest transverse diameter, 

 highest at the doi-sal groove. Sides of head vertical. Chelicera 

 about IJ times as long as the head is high in front. Sternum 

 longer than broad. Legs rather stout. 



Dimensions. — Length of cephalothorax, <S^, 1.7 mm., ?, 

 1.8 mm. 



Length of abdomen, cJ*, 1.2 mm. ; ?, 2.3 mm. 



Length of first leg, ?, 4.8 mm. 



Length of second leg, 9, 4.3 mm. 



Length of third leg, $,4.2 mm. 



Length of fourth leg, ?, 6 1 mm. 



Color in Life, 9. — Cephalothorax black, a narrow white mar- 

 ginal line not extending as far forwai'd as the plane of the posterior 

 eyes; from the jDosterior eyes two brownish lines pass caudad, unite 

 at the dorsal groove, and are continued backward to the posterior 

 end of the thorax as one median band. Sternum shining 

 brownish-black. Abdomen above black, a rather irregular line of 

 5-6 white spots (the foremost two largest) on either side, and 

 indistinct transverse lines of while on the posterior dorsum ; venter 

 dark-gray owing to scattered white hairs on a black ground, a 

 narrow white semicircle around the anterior edge of the spinneret 

 prominence. Chelicera, maxillce and labium almost black. Legs 

 pale-brownish, paler below, a black ring at the distal ends of the 

 first and second femora. Palpi colored like the legs. 



Color in Alcohol, ?$. — Cephalothorax greenish-brown, at the 

 anterior end of the median groove a dark triangular mark from 

 the anterior end of which a narrow yellowish line, bordered on 

 each side by a brown line, passes to the second eye row; a narrow 

 yellow line arises on the lateral margin of the second eye row, 

 passes around the lateral margin of the third eye row, and it and 

 corresponding line of the opposite side converge caudad, border 

 the triangular dark spot, and unite behind the latter as a narrow 

 yellow line which passes to the posterior end of the cephalothorax;
